I've been doing some design lately for my DS Lite AIO. I realized that if I wanted to change the form factor of my board, I'd need to rewire everything manually on the new PCB despite it having common components. That's why I'm designing everything on small modules that can be rearranged and put ont...

I don't need a voltage divider. I'm not sure why I thought I did. I've not touched this for a while, but I'm reconsidering having all the circuits implemented on the board. It would be much easier to design a "hub" to which separately purchasable boards can be soldered. It saves soldering effort and...

I'm fascinated with displays like this because they're incredibly cheap. I've noticed that a lot of them with high pin counts support 16 bit 8080 parallel interfacing. Ideally, I'd like to be able to connect one of these to a Pi in parallel mode. SPI is too demanding on the Pi and results in slow di...

Holy $#!%. That is some incredible surfacing you've done! I'm tempted to reprint my custom designed GB3 just so I can try to get a finish like that! What kind of durability are you getting out of that? It looks absolutely gorgeous. A+

Awesome, thanks! I just ordered some of those boards (should make testing much easier).

I should mention that I'm not using a driver board on the LCD. I have the pure LCD panel and I've soldered some wires directly to the pins on the ribbon connector. Because I can't find datasheets for these displays, I've just been going off of the pinouts provided by the sellers' pages. However, I c...

Hey guys, I'm developing a board to connect an arduino to an ILI9341 touch screen . To make things simple, I'm using the same 18 pin screens Helder uses. I've encountered one problem, though. As I'm testing on a breadboard, I don't know what to do with the SDA/SDO lines. I know I'm supposed to conne...

This MintyPi is a bit special. In addition to the button deck being wrapped in carbon fiber, it has a custom designed slim bezel that allows it close perfectly flat. It's been fully tested and works entirely except for a single stuck pixel. The altoids tin has been CNC'd for cleanliness. I will only...

My MintyPi is entirely complete, but the Pi stopped booting last night. I suspected it was the SD card, so I replaced it and it worked for another boot. Again, it stopped booting. This time, I disassembled it and did a continuity check. I noticed that the SD card was extremely hot. I haven't tried a...
