Esp32-fan controller
merlindorin/esp32-fan-controller
A small KiCad board to keep my home server cabinet cool. 4 PWM fans, 4 temperature probes, one ESP32.

PCB with vintage camera looking footage. A microphone and a fisheye lens.
Fishy8 is an open-source printed circuit board by EmanuelKrabNL, from the EmanuelKrabNL/Fishy8 repository on GitHub, published under the MIT licence. It is a 2-layer board of 100 × 100 mm with 15 parts on 8 nets, routed with 48 tracks and 0 vias.
It is built around the MF-R050. Its parts include 4 connectors, 2 capacitors, 1 resistor, 1 diode and 1 fuse. It belongs with the audio and music boards of this library.

Okay, name explained first FISHeYe lens + hi8 = FISHY8! Original name was FISH8 but FISHY8 sounds more jolly.
Those old sony handycams are increndibly hard to get. Except if you live near the old camera market in barcelona (I still hate that it wasnt open when i was there.), so, why not make one that costs a one time payment of max 120 bucks, and doesnt require extra additions like those 100 dollar converters. but has a 15 dollar converter inside of it! SSo its basically an old camcorder replacement, that i made myself!
The caddx ratel 2 (camera), is analog, thus producing cvbs footage. If we add a cvbs to usb c converter, we can make it 'act' like a webcam, and get that old, fissheye looking footage directly on our phone!
this project does not require any firmware, and gets over the 30 dollar limit. I will pay for it with my own money, therefore, the 30 bucks will help, but it wont be enough.
Well, basically just put all the cables where they belong (lol), use another usbc - usbc cable to plug your phone into the gracetop converter, and then use an external android camera app that can detect other sources to acutally film the footage. The included 'joystick', can control if you want your video to be ntsc or pal, and other on screen information, like time etc.
For the Bom file, please go here! Read the Bom file for this project.
(I dont really know how to link files, but i think it needs to be done like this)
I got a fpv camera with fisheye built in, for easyness: footage looks like this:
so, allat of yap. what does it look like?

ehh not the pretties, but gets the job done LOL!
I am planning to make a 3d print later on, zo the additional components can snap on! It doesnt need any firmware, since android supports the gracetop cvbs to usb c natively.

HeyPCB/hello-8051
HELLO: a tiny 8051 computer shaped like a 1984 desktop. AT89S52, 32 KB SRAM, 128x64 ST7920 LCD, USB-C. 112 x 158 mm 2-layer KiCad 10 board, DRC clean, firmware that writes hello. Built through HeyPCB's MCP server.
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
15 parts, built around the MF-R050. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the EmanuelKrabNL/Fishy8 repository on GitHub, at the commit this page was made from: the board is project files/FISHY8.kicad_pcb and its schematic project files/FISHY8.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
