Day 1
Today, I started some research about how I could do this, and I think I want to try and make a Attiny85 dev board thing (or something like that!). Andddd I found some resources:
- https://www.microchip.com/en-us/product/attiny85
- https://github.com/tomasr8/attiny85-dev-board
- https://github.com/SpenceKonde/ATTinyCore/blob/v2.0.0-devThis-is-the-head-submit-PRs-against-this/avr/extras/tinyNeoPixel.md
Weeeell, lets just say I didn't really understand the datasheet... Still, I did some googling and found some examples. I guess what they usually have is like, the chip, a voltage regulator, a bunch of resistors.. diodes... etc.. looking at the example though, it made me understand more, which was awesome :D
The Plan
sooo here's what I'm gonna like add;
- battery
- built in neopixels or some led
- usb-c?
Day 2
I did the schematic!! I kind of just followed an open source board but I used a usb-c and used smd components. I also added some neopixels :3 There's this tp4056 to charge the battery through the usb and i hope it works.
(I wrote this on day 3 tho)
I looked at an open source board I found on github, yea.. and I think I want to try to use a hot plate so I guess there's like smd components (?) Btw tysm acon, I got on a call with acon and she help me with my usb c :3
Day 3
Today, I finished the schematic and added footprints.. uhh I will add to this a bit later cuz I need to do some stuff :( Here's the pcb thing! without the wires connected tho
I don't know what to write here, but I guess... it looks pretty.. nice?
Day 4
I spent around 2h routing the pcb! This is the end result and its like 4 layers. While routing the pcb, I kinda selected the wrong footprint for resistors so I had to redo some stuff.
But then like there's this problem at the usb-c so idk how to fix it...
