DIY through hole plating of PCBs

Monday, October 30th, 2017

Jan Mrázek documented his experience experimenting with DIY through-hole plating of PCBs: I’ve been thinking about though hole plating for several years. The general procedure is simple – you have to activate non-copper surfaces (make them conductive) and then you apply standard electroplating procedure. You can find many tutorials on...

Pimp your PCB businesscard full color

Wednesday, July 26th, 2017

Here is a nice PCB businesscard @ smdprutser.nl As a good electronic hobbiest tradition I started to design a businesscard from PCB material. Downside of all the businesscards (and PCBs in general) is the limited number of colors you can use: FR4, soldermask (with or without copper behind it), silkscreen...

Printed Circuit Board V-Groove cutting machine

Wednesday, January 11th, 2017

[embed]http://www.youtube.com/watch?v=Ca99QRu6AQA[/embed] This is how V-Grooves are cut into PCBs. V-Grooves are half-cuts into the PCBs that allow them to be snapped apart easily. Minimum V-Groove cut length in generally 8cm due to machine cutting length. V-Grooves must be cut across the entire PCB length, it is not possible to make...

OTGW panel

Friday, August 12th, 2016

Onno designed and built his own OTGW panel with Dirty Board PCBs: Added all together and had a working gateway. This gateway has also connections for status LED’s. However, I didn’t find anything about getting the LED’s connected and build in the housing. So there started the first idea of designing my...

Dirty PCBs review from Big Mess o’ Wires

Friday, June 3rd, 2016

Dirty PCBs detailed review by Big Mess o' Wires: Now for the key question: were the boards any good? From my inspection, I’d say mostly yes. I spent a long time examining the boards under 10x magnification, and comparing them to my original EAGLE files, and to the Gerbers using gerbv....

An Android TV-stick baseboard

Saturday, May 7th, 2016

Necromant designed and built an Android TV stick baseboard: The idea was dumb simple. I needed a USB hub, since TV sticks don’t have many USB ports included. I needed GPIOs, so I threw in an attiny2313 that occupied one of the HUB’s ports, I needed a few relays and...
