Hi,
here’s an incomplete list of hardware I already own:
- 3x ESP32-S3-N16R8
- 1x OV2640 cam
- 3x ESP32-NodeMCU
- 4x Raspberry Pico 2W (RP2350)
- 1x Arduino Uno
- 2x Raspberry Pi Zero 2W
- 5x 2-channel optocoupler relay modules
- 1x 1-channel relay galvanically isolated
- 5x Logic Level Shifter 3.3V <-> 5V (I2C compatible)
- 2x LoRa Hats for Raspberry Pico 2W
- 1x OLED Display Hat for Raspberry Pico 2W
- 1x eInk Display Hat for Raspberry Pico 2W
- 1x LCD Display
- 2x 3,5" Resistive Touch Displays
- 5x IR-Sensor
- 5x IR-Transmitter
- 1x Waveshare Solar Power Manager D
- 1x Solar Panel 18V10W
- 3x 3300 mAh batteries
- 1x RTC-module
- 2x Temp sensor
- 1x NFC-Reader + Cards + Tags
- 1x Dual GPIO extender for the Pico 2W
- 1x Motor
- Resistors
- Capacitors
- microUSB / USB-C wires
- Multimeter
- A solder station
- Jumper wires
- Breadboards
Is there anything I’m missing? I usually like to do stuff with encryption, machine learning, transmission of data, controlling devices.


Off the top of my head
You can use a Pi Pico to make a pretty decent 24 channel USB logic analyzer if you don’t mind ordering a PCB and soldering it up.
I was looking for something around 10$. I saved it to my bookmarks if I ever need something larger. I also noticed that (ready-to-sell) 24 channel logic analyzer are extremely expensive, pheeew. This could be a business idea! :)
Do you have any specific recommendation?
I was looking into:

I’d probably do the last one. Not sure how reliably it will be but will certainly be better than nothing
