Etching PCB resist with an LS3020 laser cutter

This time we tried making a PCB with no “filled plane” between traces. Normally we flood fill all the spaces between traces, just so that the ferric doesn’t have as much exposed copper to etch away. But out of interest, we made up a PCB with no ground …

Meet the sponsors: Create

Brighton Mini Maker Faire is only made possible by the community of visitors, volunteers, makers and sponsors that support us. We’re particularly grateful to our early-stage sponsors; people who enable us to do important things like securing a venue, which … Continue reading

A Real Code Retreat

A real code retreat would be a month of slow hacking + tea brewing. No one would speak. We’d lake swim. We’d delete all the code at the end.

ARPIE – Arduino based MIDI arpeggiator kit

Since I made my first Arduino-powered MIDI arpeggiator a couple of years back I have been meaning (and promising) to get a kit together so others can build their own. Today I listed my first “fundraiser” on Tindie. Hopefully that will raise enough cash…

Soldering fail

Our laser-cut pcbs were certainly quicker to make than using laser-etching (we converted the pcb image to vector and cut out from around the traces rather than using the laser to etch a rasterized bitmap image) and the ferric chloride made a great job …

Contact etching pcbs with lasered paint mask

It’s cold and wet and the nerd cupboard seems such a long way away, and we’ve a pcb here that needs etching. Making up a batch of ferric seems like a bad idea, and storing it in the house could be a pain. What to do?On one of the instructables pages, s…

Laser etching PCBs instead of CNC routing

Well, our last post created a bit of interest – although some of it was just asking for clarification: we’re not really etching the PCB with the laser cutter – it’s still a copper clad board and the laser cutter still can’t cut through anything metalli…

Laser cutting PCBs

Laser cutting? That’s right! We’re not laser etching here, we’re laser cutting!We took our PCB design and using Inkscape converted all the strokes into paths. Then, joined all the paths together using the union tool (it took about 45 seconds for the co…

Back to a modular pcb-based board game

Having tried a non-pcb based board, and found it too fiddly, we’re now re-visiting the idea of a pcb-based module for our board game. But we need to address some of the issues that made us think abandoning it was the right approach.The first thing is t…
