If you’ve enjoyed Guillermo Amaral’s electronics projects such as the Canon DSLR WiFi Remote, Raspberry Pi PSU, UARTMatic 3000+, Keypad Submodule and many more, then please consider giving to his cancer treatment fund:
Gamaral’s Cancer Treatment
I’ve unfortunately had to flip the bill for my two past surgeries and my on going cancer treatment… and as you can imagine, I’m running out of cash.
If you like my content and/or have found my published projects interesting or useful, please consider sending me some spare change and I’ll be ever so grateful.
Here are couple great project videos by Guillermo on YouTube:
