Ultimately, the goal of the reels is to spin and match up win or loss combinations for a player&#39;s payout.</p><p>3. &nbsp; &nbsp;Processor: The processor is the backbone of the slot machine. It controls all the game&#39;s rules and functions and generates random outcomes for each spin.</p><p>4. &nbsp; &nbsp;Bill acceptor: This is an essential slot machine component that rejects fake bills and accepts valid currency as payment for playing the game.</p><p>5. &nbsp; &nbsp;Audio System: The sound system consists of speakers that produce upbeat music, beeps, jingles, and other complex musical arrangements to create an exciting and engaging gaming experience for players.</p><p>6. &nbsp; &nbsp;Display screen: These are screens such as liquid crystal display (LCD), organic light emitting diode (OLED), 3D technology, and a light emitting diode (LED) that showcases various symbols and animations to provide vital information that informs the decisions of the game players and enhances a visually appealing gaming environment.</p><p>7. &nbsp; &nbsp;Buttons: The primary use of the buttons is to allow players to control the game by selecting the &quot;spin&quot; button to start the game, the &quot;bet max&quot; button to place the maximum bet possible, and the &quot;cash out&quot; button used to retrieve any winnings and end the game.</p><h2>Applications of SBCs in casino slot machines</h2><p>As technology revolutionizes the gaming industry with advanced and innovative gaming features, <a href="https://www.okdo.com/smart-world/automated-fruit-slot-machine-preventative-maintenance-solutions/?utm_source=wevolver&utm_campaign=rock&utm_medium=affiliates&utm_content=casino_slot_machines" target="_blank" rel="noopener noreferrer">slot machine</a> manufacturers turn to single-board computers (SBCs) as an efficient computing solution. SBCs are compact, energy-efficient, and versatile computing devices that integrate a computer&#39;s necessary components onto a single circuit board. [2]</p><h3>How SBCs are utilized in casino slot machines:</h3><p>1. &nbsp; &nbsp;Game Control: SBCs control the game logic and mathematical models that can be put into a program to generate random numbers required for spinning the reels and the payout calculation.</p><p>2. &nbsp; &nbsp;Player Interaction: Through the implementation of features such as motion sensors, and touchscreens via the I/O ports and HDMI ports, SBCs can help to manage the user interface by controlling the buttons, enhancing sound effects, and driving high-resolution screen displays. By incorporating SBCs, casinos can create a more exciting and immersive gaming experience.</p><p>3. &nbsp; &nbsp;Seamless Communication: SBCs have Bluetooth and Wi-Fi connectivity features that enable them to communicate, interact and transmit data with the backend systems of the casino.</p><p>4. &nbsp; &nbsp;Multi-functionality: SBCs have powerful processors that simultaneously implement multiple threads, tasks, and programs in casino slot machines. With its versatility, more casinos are adopting the SBCs technology to enhance their gaming offerings, such as keeping track of spins, offering bonus rounds, detecting malfunctions, and preventing fraud.</p><p>5. &nbsp; &nbsp;Protection and monitoring: SBCs can greatly enhance a safe and more secure gaming experience by implementing advanced security features such as encryption, authentication, remote monitoring, and access control. These measures help detect and alert operators of any suspicious activity, prevent unauthorized access and tampering with the software, and ensure the integrity of the games.</p><h2>Using single board computers (SBCs) to develop cutting-edge casino slot machines</h2><p>In enhancing the features of the new types of <a href="https://www.okdo.com/smart-world/automated-fruit-slot-machine-preventative-maintenance-solutions/?utm_source=wevolver&utm_campaign=rock&utm_medium=affiliates&utm_content=casino_slot_machines" target="_blank" rel="noopener noreferrer">casino slot machines</a>, SBCs offer several distinct advantages over computing systems like the Field-Programmable Gate Array (FPGA), microcontrollers, and other traditional computing solutions. Let&#39;s take a look at some of the advantages of using SBCs over other computing solutions for casino slot machines:</p><p>1. High Computational Ability: Single-board computers (SBCs) are becoming increasingly popular among developers due to their high computational ability. Unlike microcontrollers, FPGA, and other traditional computing solutions, SBCs have expandable-storage capabilities, graphics capabilities and high-speed processors typically based on x86, Arm&reg;. This advanced technology allows developers to create complex gaming algorithms and features such as multi-level bonuses, free spins, 3D graphics, and better sound effects previously impossible to achieve with other computing solutions. With SBCs, developers can achieve high-performance levels previously out of reach.</p><p>2. &nbsp; &nbsp;Flexible and Compact: Modern casino slot machines require cutting-edge hardware and software to deliver exciting gameplay experiences to users. One of the biggest advantages of using Single Board Computers (SBCs) for these machines is their small form factor. Unlike traditional computing systems that require bulky hardware configurations to accommodate cooling systems, power supplies, and hard drives, SBCs are compact devices that offer a range of input and output options. This makes it easy for game developers to modify or incorporate new features without worrying about physical constraints. &nbsp;Another inherent advantage of using a computer consisting of one board is reliabilaity vs. traditional computing devices. &nbsp;A slot machine is exposed to extensive vibrations and temperature fluctuations, an SBC is immune to various duaghter boards becoming lose over time.</p><p>3. &nbsp; &nbsp;Reduced Energy Usage: Unlike traditional desktop computers, which require a lot of energy to operate, SBCs are designed to run on low power, making them generate less heat and extending the lifespan of the casino slot machine. &nbsp;This efficiency is multiplied as the HVAC system isn&rsquo;t required to work as hard to remove exess heat from a casino full of PC powered machines thus saving the establishment considerable costs in energy and a reduction in global warming.</p><p>4. &nbsp; &nbsp;Customizable: Another advantage of using SBCs for creating modern casino slot machines is their high degree of customizability. Slot machine manufacturers or developers can choose from various SBCs with different clock speeds, processing power, memory, and connectivity options and configure them to meet their specific requirements. This level of flexibility allows manufacturers to create innovative, unique, and engaging gameplay.</p><p>5. &nbsp;Cost-Effective: Another significant advantage of SBCs over other computing solutions like FPGA and microcontrollers is their affordability. Compared to traditional computing solutions, which require many components, such as electronic modules, cooling systems, and power supplies, SBCs are compact devices that require only a fraction of the hardware components. This reduction in hardware components reduces production costs and helps minimize failure rate, reducing downtime and maintenance costs. &nbsp;Another advantage of using Linux or Android powered devices is the wealth of software engineers available compared with the relatively niche skillset of FPGA programmers.</p><h2><strong><em>About the sponsor: ROCK 5 Model B single-board computer powers new Casino Slot Machines</em></strong></h2><p>Gaming technology requires sophisticated algorithms, graphics, real-time communication, and secure storage for sensitive player data.

Developing flexible vehicle tracking systems with SBCs

<p dir="ltr" id="isPasted">It is no surprise that EV charging is at the foundation of the automotive industry&rsquo;s transformation to electric vehicles. Whether it is public charging stations or wall chargers in our garages, EV chargers are in increasingly high demand today, with more and more electric vehicles on the roads.</p><p dir="ltr">A&nbsp;<a href="https://www.pwc.com/us/en/industries/industrial-products/library/electric-vehicle-charging-market-growth.html" target="_blank">PWC study</a> projected that the number of electric vehicles in the United States alone is to reach 27 million by 2030 and no less than 90 million ten years later. To accommodate that, PWC analysts estimated a 775% growth rate in the number of charge points to hit 35 million in 2030.</p><p dir="ltr">Across the pond, a&nbsp;<a href="https://www.gov.uk/government/publications/electric-vehicle-charging-market-study-final-report/final-report" target="_blank">2021 report</a> by the Competition and Markets Authority in the United Kingdom suggested a ten-fold increase in the number of public charge points by 2030 to reach at least 280 to 480,000 locations.</p><p dir="ltr">But the trend is not merely about EV charger installation. The technology behind these chargers is also developing quite rapidly. Be it for charging speed, power consumption, connectivity, or portability, what lives inside the charging unit is what makes or breaks the adoption of electrification in the automotive industry.</p><p dir="ltr">This brings us to the computing device inside the charger, otherwise known as a Single-Board Computer (SBC). An SBC is a full-functioning computer mounted onto a single circuit board. It includes the microprocessor(s), memory, input/output&nbsp;peripherals, and other elements. It is an embedded device that is preferred for a wide array of applications, one of which is EV chargers.</p><h2><span style='font-family: "PT Sans", serif; font-size: 26px; font-weight: 700; background-color: transparent; color: rgb(0, 0, 0);'><strong>Why are SBCs so important for EV charging?</strong></span><strong><br></strong></h2><p dir="ltr">While EV charging is a demanding application, SBCs provide several important benefits that indicate significant potential in this market. From computing power to low design effort, portability, and supply chain minimisation, the technological and commercial advantages brought forth by SBCs are what push the adoption of EV chargers forward.</p><p dir="ltr">Certainly, the most important attribute that underlies all the others is reliability. These embedded controllers have a long track record of steadfast performance, which is crucial to the functionality of EV chargers. Whereas desktop computers, for instance, are promoted for their adaptability based on user preferences, SBCs&rsquo; simple and robust structure results in much fewer issues and minimal downtime, rendering them the preferred option for devices that require constant activity and reliability.</p><p dir="ltr">Here are the top 5 advantages of SBCs that EV chargers can make use of:</p><ol><li dir="ltr"><h3 dir="ltr">Portability and customizability</h3></li></ol><p dir="ltr">SBCs are compact in size. They are ready-to-use controllers that are embedded in and integrated with any EV charger system no matter how limited the space is.&nbsp;</p><p dir="ltr">As EV charger designs vary in size based on where and how they are used, the space inside can be quite confined. SBCs&rsquo; compactness can help solve a lot of design challenges as they can fit in almost any functional design.</p><p dir="ltr">In addition, SBCs can be customised to fit not only any design but also any functionality. With a fully configurable design, a user can choose what components to have on the board, how small the SBC should be, and how they connect to the end application.</p><ol start="2"><li dir="ltr"><h3 dir="ltr">Compatibility</h3></li></ol><p dir="ltr">SBCs are typically designed to work with different types of hardware and run a variety of operating systems and software applications. This compatibility enables their use with any system.</p><p dir="ltr">Whether it is operating systems, such as Linux, Windows, or Android, or software applications, such as web servers or programming languages, SBCs can be designed to provide such compatibility and enable easy operation. As for hardware, SBCs have a variety of options for processors, storage, RAMs, and peripheral input/output interfaces, such as HDMI and USB ports.&nbsp;</p><p dir="ltr">While not all SBCs fit all applications, there is always an SBC for an application. And this compatibility is important for EV charging units running on different systems.</p><ol start="3"><li dir="ltr"><h3 dir="ltr">Low cost and power efficiency</h3></li></ol><p dir="ltr">It is trivial to realise that SBCs are cost-efficient. Their minimal size and compactness lead to a lower cost than relatively larger, traditional computers. Combining multiple components of a system on one module is a massive step towards minimising the cost of materials and manufacturing.</p><p dir="ltr">But lower cost does not come at the expense of efficiency. SBCs are required to be at high efficiency to provide sufficient serviceability in EV chargers. That is why they are designed with efficiency in mind, supporting both public and domestic EV charging units.</p><ol start="4"><li dir="ltr"><h3 dir="ltr">Connectivity and Monitoring</h3></li></ol><p dir="ltr">Connectivity is at the core of network and remote systems. EV charging requires such a feature, especially in networks like smart grids. For instance, SBCs can be used to communicate with smart grids, enabling chargers to adjust their charging rates based on grid demand and the availability of renewable energy sources. SBCs can also communicate with connected vehicles, allowing for automatic charging initiation and the transfer of charging data between the vehicle and the charging station.</p><p dir="ltr">With such functionality, SBCs in EV chargers would be able to help with handling complex tasks such as real-time monitoring for preventive maintenance, data collection, and analysis. This enables EV chargers to offer a variety of services, such as remote charging management, billing, and payment processing.&nbsp;</p><p dir="ltr">With the use of SBCs, EV chargers can collect and analyse data on energy consumption, charging patterns, and user behaviour, creating more efficient charging solutions.</p><ol start="5"><li dir="ltr"><h3 dir="ltr">High performance and low power consumption</h3></li></ol><p dir="ltr">Applications that include embedded systems like SBCs require a certain level of power efficiency, in which the ratio of performance-to-power consumption is as high as possible. EV chargers are no different. In fact, the EV charging speed is highly dependent on the processing power level.</p><p dir="ltr">SBCs have the capacity to provide that, given their cutting-edge components and architecture. In fact, researchers have studied&nbsp;<a href="https://www.sciencedirect.com/science/article/pii/S0167739X1833142X?via%3Dihub" target="_blank">the performance of SBCs and SBC clusters</a> and found that recent developments in SBCs have seen an increase in performance followed by an increase in energy efficiency and value for money.</p><p dir="ltr">For a demanding EV charging market, SBCs are a strong fit as an embedded processing solution to provide sufficiently high performance while saving on energy consumption.</p><p dir="ltr">Yet, with all the advantages SBCs offer, they still constitute a growing industry. This means there are always challenges to be tackled. From processing power to limited storage and memory capabilities, heat dissipation, and security risks, the challenges ahead of SBCs may still need to be solved. However, the constant development of SBC technology shows a huge potential in overcoming such challenges and playing an increasingly important role in the development of smarter, more sustainable EV charging solutions.</p><p dir="ltr">&lt;image&gt;</p><h2><span style='font-family: "PT Sans", serif; font-size: 26px; font-weight: 700; background-color: transparent; color: rgb(0, 0, 0);'>An SBC to help push electrification: The ROCK series from OKdo</span></h2><p dir="ltr">The all-new <a href="https://www.okdo.com/c/rock-shop/rock-sbc/?utm_source=wevolver&utm_campaign=rock&utm_medium=affiliates&utm_content=ev_charging" target="_blank" rel="noopener noreferrer">ROCK series</a> of SBCs from global technology company <a href="https://www.okdo.com/?utm_source=wevolver&utm_campaign=rock&utm_medium=affiliates&utm_content=ev_charging" target="_blank" rel="noopener noreferrer">OKdo</a> has hit the market with cutting-edge features that can help engineers <a href="https://www.okdo.com/smart-world/ev-charging-stations-smart-ev-charging-solutions/?utm_source=wevolver&utm_campaign=rock&utm_medium=affiliates&utm_content=ev_charging" target="_blank" rel="noopener noreferrer">develop innovative EV charging solutions</a>.&nbsp;</p><p dir="ltr">Here are some of the most prominent features you can find in ROCK series of SBCs.</p><div align="left" dir="ltr"><table><tbody><tr><td><p dir="ltr"><strong>Powerful SBCs</strong></p></td><td><p dir="ltr"><strong>Flexible and Compact SoMs</strong></p></td><td><p dir="ltr"><strong>Fully Customisable SBCs</strong></p></td></tr><tr><td><p dir="ltr">High-performing Hexa-core Rockchip RK3399-T processor</p></td><td><p dir="ltr">Compact size for easy integration into different designs</p></td><td><p dir="ltr">Develop low-cost and efficient applications for embedded systems</p></td></tr><tr><td><p dir="ltr">Wide OS compatibility, including Android</p></td><td><p dir="ltr">Reliable &amp; Powerful Rockchip RK3566 SoC</p></td><td><p dir="ltr">Fully configurable design</p></td></tr><tr><td><p dir="ltr">Expandable storage capability</p></td><td><p dir="ltr">Quad-core Arm&reg; Cortex&reg;-A55 CPU</p></td><td><p dir="ltr">Add or remove components</p></td></tr><tr><td><p dir="ltr">Supporting 4K &amp; 8K displays</p></td><td><p dir="ltr">Flexible storage &amp; wireless connectivity</p></td><td><p dir="ltr">Your board, your way</p></td></tr></tbody></table></div><p dir="ltr">With OKdo&rsquo;s mission to &ldquo;deliver imagination, creativity, and technical expertise&rdquo; to help product developers generate new ideas and turn them into commercial reality, the ROCK series is a clear representation of what <a href="https://www.okdo.com/?utm_source=wevolver&utm_campaign=rock&utm_medium=affiliates&utm_content=ev_charging" target="_blank" rel="noopener noreferrer">OKdo</a> does.</p><p dir="ltr">Choose between ROCK 3 Series, ROCK 4 Series, or ROCK 5 Series, and customise your board to fit your EV charger.

We are all set to make our first Formula Student Electric Vehicle this year. Our battery pack is a 100S5P of Molicel INR-21700 P42A cells. It is divided into five segments of 20S5P. The battery pack is designed to be 81 kW peak power, 420 Ah capacity, 350V, 250A discharge current, and 20 A charging current.&nbsp;</span></p><p dir="ltr">Lithium-ion cells require constant monitoring for proper charging/discharging. After looking at multiple off-the-shelf BMS, our team decided to make a BMS of our own. The BMS monitors every cell voltage and at least 30% of the cell temperatures., in compliance with the FSAE rules. The designed BMS should provide additional protection to the cells during charging and discharging by using passive cell balancing controlled by the BMS onboard controller, which controls the bleed FETs.&nbsp;</p><p dir="ltr">The BMS will be organized in a master-slave architecture with five slave boards for the five segments of the battery pack. The master board will be connected via a CAN bus to the 5 slave boards and will perform State of Charge (SoC), State of Health (SoH), Range, and Power Estimations. It will also perform diagnostics on the battery pack to determine overtemperature, under-temperature, overcurrent, under-voltage, and overvoltage faults and would open the Accumulator Isolation Relays through a relay driver if the fault is critical.&nbsp;</p><p dir="ltr">Otherwise, in case of a non-critical fault, it would derate the system by communicating with the Vehicle Control Unit (VCU) over RS-232 or CAN. The master board also passes certain management commands to the VCU and its slave boards via CAN or RS-232, as applicable.&nbsp;</p><p dir="ltr">The master board also acts as a data logger for the BMS. It logs all cell voltages, temperature, segment currents, and pack current on an onboard micro-SD card. This data can be used for analysis and to design a better battery pack for the upcoming iterations of the car.&nbsp;</p><p dir="ltr">Each segment will contain 33 thermistors placed on the negative terminals of the cylindrical cells. The thermistors are optimally placed in the battery pack so that no cell can go undetected beyond the temperature threshold of 55 degrees (image attached). Each slave board contains 6 LTC6813 18-Cell Battery Stack Monitor chips for monitoring the 100 cells. LTC6813 communicates with the Rockchip by using an isoSPI interface. The LTC6813 implements passive balancing using external resistors and transistors to remove excess energy from the most charged cell. The BMS Slave contains 100 sets of the same components since each cell needs its own circuitry.&nbsp;</p><p dir="ltr">The BMS will have to deal with 500 voltage readings (with a precision of 2 mV), 165 temperature readings, and 6 current readings (5 x segment, 1 x pack). It will have to use this data to diagnose each cell and estimate SoC, Range, SoH, and power requirements. It is imperative to large a high main memory to perform these many operations. Rock 5B comes equipped with 8 GB LPDDR4x SDRAM which is ideal for dealing with the volume of data that comes through it.&nbsp;</p><p dir="ltr">The project would satisfy the following objectives:</p><p dir="ltr">&bull; Build a custom BMS solution for TeamKART Motorsports</p><p dir="ltr">&bull; Add a foundation for the state of charge measurements</p><p dir="ltr">&bull; Reduce the number of wiring failure points</p><p dir="ltr">&bull; Optimise for cylindrical 21700 cells</p><p dir="ltr">&bull; Improve charge and balance time</p><p dir="ltr">&bull; Add integrated temperature sensing board</p><p dir="ltr">&bull; Improve overall system robustness</p><p dir="ltr"><span class="fr-video fr-deletable fr-fvc fr-dvb fr-draggable" contenteditable="false" draggable="true"><iframe width="640" height="360" src="https://www.youtube.com/embed/JSdIKUr9uXM?&wmode=opaque&rel=0&enablejsapi=1&origin=https://www.wevolver.com" frameborder="0" allowfullscreen="" class="fr-draggable" data-lf-form-tracking-inspected-kn9eq4roawkarlvp="true" data-lf-yt-playback-inspected-kn9eq4roawkarlvp="true" data-lf-vimeo-playback-inspected-kn9eq4roawkarlvp="true"></iframe></span><br></p><h3>Jeffrey Higgason</h3><p dir="ltr"><em>Accessible drone technology</em></p><p dir="ltr"><span class="fr-img-caption fr-fic fr-dii" style="width: 758px;"><span class="fr-img-wrap"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNjc2NTU0MzEyMDU1LTE2NzY1NTQzMTIwNTUucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" width="602" height="524" class="fr-fic fr-dii"><span class="fr-inner">Image credit: Jeffrey Higgason</span></span></span></p><p>Our team at Charity 1.0 is a 501c3 non-profit that is looking to make technology accessible.

The camera also allows for avoidance-based algorithms to make the drone incredibly easy to fly in a small area.</p><p dir="ltr">Later versions of our project plan on introducing a 360 lidar and 3D printed frame for the sUAS.&nbsp;</p><p>Based on our current research, cost-effective sUAS solutions do not exist that gather information and promote safer initial response efforts while providing valuable intelligence.</p><p><strong>The project&#39;s primary objectives are:</strong></p><p dir="ltr">&bull; Design, build, test, and demonstrate sUAS solutions that address the primary need associated with flying a sUAS in an indoor and constrained environment.</p><p dir="ltr">&bull; Develop innovative solutions that further enhance the first responder&rsquo;s ability to gain situational awareness of the indoor environment.</p><p dir="ltr">&bull; Develop a product at an affordable price that meets the budget of a public safety agency.</p><p dir="ltr"><strong>Use cases:</strong></p><p dir="ltr">&bull; Collapsed buildings</p><p dir="ltr">&bull; Operations under dense canopies</p><p dir="ltr">&bull; Indoor barricaded suspect</p><p dir="ltr">&bull; Indoor hostage situations</p><p dir="ltr">&bull; Indoor active shooters</p><p dir="ltr">&bull; Structure fires</p><p dir="ltr">&bull; Partially flooded buildings</p><p>Operating sUAS indoors in a constrained environment (e.g., limited lighting, compromised structural integrity, lack of global positioning system, or GPS-denied environment) presents many challenges for first responders who may be responding to an ongoing incident. Before inserting first responders into an unfamiliar environment, assessing the risks and obtaining better situational awareness could be critical to mission success and the safety of victims, survivors, bystanders, and first responders.&nbsp;</p><p>While there are sUAS solutions available in the market, these solutions typically cost more than what a local public safety agency might be able to afford. Additionally, it may be too difficult to operate a UAS in a small room or building without visual line of sight (VLOS), autonomous capabilities, and additional sensors. Also, information provided to incident command may not have sufficient fidelity or interpretability to be actionable. The objective of this project is to provide user-friendly, affordable solutions for first responders to accomplish their missions involving indoor environments.</p><h3><span style="background-color: transparent;">David Tischler</span></h3><p dir="ltr"><em>Running&nbsp;</em><a href="https://www.wevolver.com/profile/edge.impulse" rel="noopener noreferrer" target="_blank"><em>Edge Impulse</em></a><em>&nbsp;on the Rock 5B</em></p><p dir="ltr"><span class="fr-img-caption fr-fic fr-dii" style="width: 758px;"><span class="fr-img-wrap"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNjc2NTU0MzE4MTM0LTE2NzY1NTQzMTgxMzQucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" width="602" height="465" class="fr-fic fr-dii"><span class="fr-inner">Image credit: David Tischler</span></span></span></p><p dir="ltr">As the Community Developer Manager at Edge Impulse, I would like to demonstrate the Rock 5B running an Edge Impulse machine learning model!</p><p dir="ltr">I suspect that for now, we will need to simply use the CPU (which is of course very powerful anyways) to run our Linux CLI and perform inferencing, as opposed to the onboard NPU.
