Using an overpowered vape as a secondary display

Last week, we noted that it was possible to run a web server on a disposable vape through its USB-C port, and now I’ve been shown DOOM on an even more overpowered vape acting as a secondary display, which is a bit larger in size than the WeAct Display FS 0.96-inch USB display we just covered. Perhaps I should add a ‘vaporware’ category on CNX Software… The new hack was done by Aaron Christophel (ACT1441) using an Aspire PIXO Vape with a Cortex-M4F MCU, a small color LCD, a USB-C port, Bluetooth LE connectivity, and a battery. Aspire PIXO vape hardware specifications: MCU – Puxa PY32F403XC Arm Cortex-M4F microcontroller @ 144 MHz with 64KB RAM, 256KB Flash Storage – External 16MB SPI Flash Display – 323 x 173 LCD Wireless – WS8000 BLE chip USB – 1x USB Type-C port Misc Heating Coil Vape microphone (designed to detect airflow from […]

Antenna hack more than doubles the range of cheap ESP32-C3 USB-C boards

There are plenty of small ESP32-C3 IoT boards with a USB-C connector on the market, and while they all look very similar, antenna designs differ, and less thought-out ones may severely impact the WiFi and Bluetooth range. Peter Neufeld decided to hack one of those cheap ESP32-C3 boards by adding a custom antenna, and this resulted in the board having more than twice the range and almost three times in some cases. Those tiny boards are cramped, so there’s very little space around the ceramic antenna typically used, leading to poor RF performance. To work around that issue, Peter added a 31mm long antenna made of silver-plated wire, making a loop of about 8mm in diameter outside of the board and soldered on the ceramic antenna’s solder joints, and the rest of the wire (about 15mm) points upwards. As you can see from the photo above, he didn’t remove the […]
