WiCAN is a powerful CAN adapter based on ESP32-C3 that can be used for car hacking and general CAN bus development. It is available in two form factors: OBD-II and standard USB-CAN. The original firmware can interact directly with RealDash using Wi-Fi or BLE, which allows you to create custom dashboards with beautiful graphics. It is available for Android, iOS, and Windows 10. WiCAN connects to your existing Wi-Fi network and any device on that network, and it allows you to configure Wi-Fi and CAN settings through a built-in web interface. Both versions have a power saving mode that detects when the voltage drops below 13 V or other preset values. When this power saving mode is enabled, WiCAN is able to enter sleep mode, reducing the current consumption to less than 1 mA.
This is a fun electronic toy car that features power-ups! The author uses color sensors and magnetic switches to trigger fun tricks like acceleration, deceleration, and rotation. It draws a lot of inspiration from Mario Kart.
After a failed Kickstarter campaign, the author has now open-sourced the software, hardware, and mechanics.
Despite the growing demand for larger battery cells, battery prices remain quite high, constituting the most expensive component in an EV or PHEV, with a typical price tag of around $10,000 for a battery that supports a range of a few hundred kilometers. The high cost can be mitigated by using lower-cost/refurbished battery cells, but such cells will also have greater capacity mismatches, which will reduce the available runtime or driving distance on a single charge. Even higher-cost, higher-quality battery cells will age and mismatch after repeated use. There are two ways to increase the capacity of a battery pack with mismatched cells: one is to use larger batteries from the beginning, which is not cost-effective; the other is to use active balancing, a new technology that can restore battery capacity in the battery pack and quickly increase power. Full series battery cells need balancing When each battery cell in the battery pack has the same state of charge (SoC), we say that the battery pack is balanced. SoC refers to the current remaining capacity of an individual battery relative to its maximum capacity as the battery is charged and discharged. For example, a 10Ah battery will automatically equalize the state of charge between parallel-connected battery cells over time as long as there is a conductive path between the battery cell terminals. It can also be argued that the state of charge of series-connected cells will vary over time for a variety of reasons. Temperature gradients across the pack, impedance, self-discharge rates, or differences in load between individual cells can cause gradual changes in SoC. While pack charge and discharge currents help to minimize these cell-to-cell differences, the cumulative mismatch will only increase unless the cells are periodically balanced. Compensating for gradual changes in cell SoC is the most fundamental reason to balance series-connected cells. Typically, passive or dissipative balancing schemes are sufficient to rebalance the SoC of cells with similar capacities in the pack.
This reference design board supports the NXP® MM912_P812 engine control IC, which combines an MCU (S12P) and an analog control chip (MC33812), and is suitable for motorcycles and other single/double-cylinder small engine control applications.
The analog control IC consists of three integrated low-side drivers, a pre-driver, a +5.0 V voltage pre-regulator, an MCU watchdog circuit, an ISO 9141 K-Line interface and a parallel interface for MCU communication.

The NXP® 15 W multi-coil transmitter reference platform is designed for AutoSAR automotive wireless charging applications based on the NXP MWCT101xS controller IC family. The platform uses automotive-grade components and other critical automotive features, including AUTOSAR software and drivers, to ensure the system can be integrated seamlessly. Complies with the latest Qi® specification from the Wireless Power Consortium and is MP-A9 transmitter type certified.
The aim of the design was to replace the existing mechanical switches for ventilation position, blower speed and temperature control with an interactive LCD based system to extend the life and robustness of the system. The system can handle events via a capacitive touchpad interface (controlled via NXP's proximity capacitive touch sensor controller PT60), an infrared remote control (available for the convenience of rear-seat passengers) or microswitches.
This valve controller system uses SB0800 octal valve controller IC with MCU and two power MOSFETs. The system can drive proportional and digital valves as well as system pumps. Monitoring and protection features protect the system from hazardous events such as short circuits, overcurrent or overvoltage, and other abnormal conditions.
