Modifying a Hotplate to a Reflow Solder Station
Versteeg Mar 16,2025
This is a project to modify a UYUE 946C model hotplate and convert it to a reflow soldering station.The UYUE 946C hotplate is modified by replacing the original controller and by adding an additional heating element. The new controller is ESP32-based and has a TFT color display. The selection of an ESP32 is because it will allow a much more responsive display than an Arduino can accomplish. Hardware SPI is used to communicate with the TFT display and the K-Type temperature sensor.The software al...

ESP32 Analog style VU meter with GC9A01 Round Dispalys + Peak Meters
Pavleski Mar 13,2025
 A typical VU meter measures audio signals and displays them with a visual indicator. In the classic VU meter design is used a moving needle (actually a sensitive galvanometer) that points to a scale on a calibrated range. The needle moves left or right depending on the strength of the audio signal. I recently acquired these small round TFT displays with a GC9A01 chip. Its basic purpose is for making smart watches, but in fact their shape is ideally suited for making a retro-look VU me...

Wall Box Mount for Waveshare ESP32-S3-Touch-LCD-4
Gardner Mar 10,2025
Lets you mount a Waveshare ESP32-S3-Touch-LCD-4 into a standard UK 1 gang wall box or pattress. The LCD screws into the mount using 4x M2.5 screws, and uses the existing M3.5 screws from a standard pattress to fix the display onto the wall. Uses keyhole slots, so the display can be removed by pushing upwards.

Motobot-with-Robotic-Arm-Schematic_PCB_Motobot-with-Robotic-Arm-Schematic_2024-10-14
Ndukwu Mar 07,2025
The RC car robotic arm is simply an RC car on wheels. The arm is a 4DOF robotic arm, meaning it has four moving parts.I used Mg90s servo motors since they are metallic, but the plastic Sg90s should work also. As seen in the schematic diagram below. I used two separate power supplies, each made up of 2S lithium ion (Li-on) batteries, one for the MCU and the other for the motors. This was to prevent interference of the voltage fluctuations and electrical noise generated by the motors from disrupti...

SuperBruce (v2.4)
37 Mar 07,2025
SuperBruce is a PCB that allows you to use all the main modules of Bruce (cc1101, nNR24l01, PN532, and IR module) together in one neat and compact package. This is the easiest way to get yourself one, and I even earn a small commission! For more info, look for it on reddit or ask me. Feel free to ask me anything!*Note: There was some bad tracing I did with the transistor on all boards before v2.4, If you have anything before v2.4 IT WILL NOT WORK. Very sorry to anyone who ordered before v2.4 but...
