Wirelessly Powered PiBook

thingiverse

This is the Wi-Fi Enabled PiBook running on the Raspberry Pi 2 Model B, with the Sainsmart 9" touchscreen display and Anker 10,000mAh battery. It wirelessly charges from the power transmitter installed under a table equipped with a transmitter. This is similar to my previously designed Wi-Fi Enabled Tesla Desk Lamp. A lower violet LED lights up when it receives a 6.5MHz signal, while an upper violet LED shows that it's receiving a steady supply of 5VDC. If wireless charging is not used, the PiBook can be built without any issues. Its normal operation and construction do not rely on this feature.

To assemble the PiBook, follow these instructions: This print was built around a Raspberry Pi 2, the Sainsmart 9" touchscreen display, and an Anker 10,000mAh battery. The system charges wirelessly using its built-in receiver coils (images 3-5). Power is transmitted through the table below where it receives power. Materials required for assembly: 1. One Raspberry Pi 2 Model B. 2. One Sainsmart 9" touchscreen HDMI display with driver board. 3. One male to male USB cable (12 inches long, but not critical). 4. One 1/8" stereo audio cable (12 inches long, not essential). 5. One male to micro male USB cable (18 inches, crucial). 6. One ultra-thin HDMI cable (12 inches, ultra-thin, and necessary). 7. One Micro-USB male to female OTG cable (6 inches, essential). 8. One male to female USB extension cable (6 inches, essential). 9. Anker Astro 10,000mAh E3 external battery. 10. A voltage boost converter from eBay, one that matches my setup. 11. 12 M3x4.5mm screws 12. Two M2.5x25mm bolts 13. Two M2.5 nylon lock nuts 14. Two silicone O-rings (6mm in diameter) 15. One small momentary reset button 16. A 1/8" stereo audio jack (from Radioshack) For optional additions: 1. Wireless keyboard with dongle, preferably using a 2.4G Mini Wireless Keyboard. 2. Wi-Pi WiFi adapter If wireless charging is skipped, these materials will create a fully functional PiBook. For adding wireless power features to the system: Materials required include four DPG15I300PA power switching diodes, Two 1N5400 rectifier diodes, One 2200uF 50V electrolytic capacitor, 2. SMD LEDs in your preferred color, specifically designed for this use case, A 1k resistor, A 10k resistor, An additional 120 resistor, A 5k potentiometer, LM338 voltage regulator, 0.1 uF ceramic capacitor, One 1uF tantalum capacitor, Three feet of copper tubing (commonly found in car accessory stores), A high frequency capacitors - specifically a 3.3 nF capacitor, capable of handling voltages at 6.5MHz
