[homemade wk6] Lora Walkie (Alpha Build)
Continued working on my Lora prototype. Made a (probably inaccurate) schematic and Eagle file. I was very surprised that I managed to stuff most of it in a 12-pin chip!! Apart from 2 SPI modules, I could fit 3 buttons and 1 LED with the rest of the free pins. Designed my first double-sided board. … [read more]

[homemade wk3] Marquee Letter Design
This week, we were each assigned a letter for a collective Marquee Sign project (> ERROR COMPILING ). We are to use Autodesk Eagle to create circuit schematics, and turn them into PCB designs. My letter is “R”. The third R. The circuit is similar to what we made last week, with an ATTiny85, capacitive … [read more]
[homemade wk2] ATtiny85 Application
This week, we learned about ATtiny85, created a jig (to upload code from an Arduino) on a perfboard, and made a sensor-LED application. ATtiny85 is an 8-bit AVR microcontroller that comes with 8-pin interface. It can use Arduino code and can operate on minimum power (3V-5V). For my application, I decided to do a capacitive … [read more]
