I recently received the custom printed circuit boards I had made by OSH Park!
This one is for a 6x voltage multiplier based on circuits I studied online. Since it's a test unit I included screw terminals so I don't have to solder to use it. For the version that goes inside an actual amp chassis I will design another slightly smaller one with solder pads.
After designing it I created the board layout in Eagle. OSH made it so easy, too. No need to generate all the various gerber layers, just upload the ".brd" file and they do all that and show you nifty previews to check over before finalizing the order! They are now going to be my fab house for the indefinite future. :)
Portsmouth Citybus Leyland Atlantean Alexander 289 (XTP 289L) on 26th October, 1989. I think this was during a period when PCB was in common ownership with Southampton Citybus?

In late 60'S, Multi-layer PCBs were very rare and expensive... Here is one sample, incredible when you think that it was hand-designed, Orcad was not invented yet...
Here's a completed pair of the etched copper earrings I've been making.
You can't quite see it here but there's a thick layer of hardened clear coat protecting the face.

I recently received the custom printed circuit boards I had made by OSH Park!
This one is for a small voltage doubler. It rectifies 12v AC current for the tube filaments of a couple of 12EL6 tubes, and doubles the voltage for the plates. I'm not yet sure how well the 100μF caps are going to smooth the current since I don't have a scope, but we'll see..
After designing it I created the board layout in Eagle. OSH made it so easy, too. No need to generate all the various gerber layers, just upload the ".brd" file and they do all that and show you nifty previews to check over before finalizing the order! They are now going to be my fab house for the indefinite future. :)

The pcb for the prototype board for one of my hardware related jobs arrived. So I spent all night hacking with Martin at Metalab :)
A lasercut frame for mounting the stencil.
This is a prototype of Stackduino v1. Please visit the GitHub project page for the completed first revision - including pcb files, parts list and code.

I finished the first draft of the pcb last night. Out of interest I got a quote for fabrication with Fritzing... 84 Euros!!!! Either I find somewhere a lot cheaper or looks like I'll be sticking with the perfboard version!
Single layer PCB IR detectors and a few others. Card format 100x160mm. I just have to cutting the different smaller PCB's.
The boards are now ready to solder the components.
DIY PCB (motor driver for tennis machine)
After etching. Toner and Green TRF still on where it protected the copper.
Early attempt at designing PCBs using ExpressPCB. The green is the back of the board, the red is the top, and the yellow is the silk screen (in case I can find a cheap enough place to make me a small batch).
