Oops, I did it again

[UPDATE] silkscreen and the upside-down side of things

An after midnight board, how classic [don't] [just] [don't]. I could have breadboarded this as well first, to check if it actually works. Damn. Now I'm hesitant to reorder, I should try it first. - Wait, what am I talking about?

This is a shield for the Wemos D1 mini, that features a TXB104D, a level-shifter with auto detection for direction. The picture seen here is the corrected version, after ordering the failed PCB. By accident I've mirrored the game boy connecter, because I tried to rotate it in my head. This version has numbered pins, to make it more easy to check. Otherwise I'm pretty proud of it. I can still use it as a breakout board for the TXB104D and check if the connector gets a clean cutout, even use the Wemos D1 mini to talk to 5V stuff.

There are "rumours" that the ESP is 5V tolerant and the Game Boy might be happy with 3V3 volts of the ESP, but I'm not eager to try. By rumours I mean, I thought I have read that somewhere.

Here is that ear worm you're trying to get rid off. Gremlins and ear worms, classic Dave.

I recently re-discovered the "view from above/view from below" button in Fritzing, which greatly helps with this kind of problems. Now I just have to remember to use it.

Are you sure? yes | no

Most of the time I use OSHparks generated preview for that, but a button seems more timesaving :)

Are you sure? yes | no

good rule! don't order after midnight, or if you've had more than 3 beers!

Are you sure? yes | no

The title alone put that song into my head... I thought maybe you just coincidentally named the project log after a terrible song without realizing it, but no, scrolling down reveals the video... Making it even more stuck in my head

Are you sure? yes | no

the title really came first, but the idea to post that video came right after that - I'm an admirer of her early works :D

Are you sure? yes | no

Seems like it still is upside down :D oh well...

Are you sure? yes | no

it has to stay this way, routing it upside - down is just punk... gotta add some more silkscreen.

Are you sure? yes | no

This slowly turns into an everything game boy project
