Seeed Studio has even more spare PCBs than we do. They’re donating some of them to PCB sculptor Steven Rodrig for his work (see above). If you’re Seeed’s 20,000th order, you’ll get one of Steven’s sculptures for free. Soon Seeed will start selling extra PCBs too, just for the cost of shipping. Scrap PCBs are […]

Surface mount layout practice
Eagle class at [NSL] shows you how to re-route Evil Mad Scientist’s through-hole ‘Larson Scanner‘ into a single-sided surface mount PCB.
Soldered prototypes
A big box of PCBs arrived earlier today. Here’s the current progress: 3 PIC USB LCD backpacks, 2 Bus Pirate v4, and a USB POV Toy. Still waiting on a couple parts, but these boards are almost done.
Big box of circuit boards
A box of PCBs just arrived from Seeed Studio’s Fusion PCB service. This batch includes: Bus Pirate v4 USB POV Toy Through-hole IR Toy PIC USB LCD backpack version We’ll be flinging lead today, watch for prototype updates later.
Bus Pirate v4, IR Toy update, 3EEPROM PCBs
A big box of PCBs arrived from Seeed’s Fusion board service today. Here are a few of the boards that have been mentioned on the blog or in the forum: An updated 3EEPROM explorer board USB Infrared Toy manufacturing update Bus Pirate v4 prototype for developers Most of these boards won’t be available for months, […]
Lazy Saturday free PCB
There’s a lot going on in the lab this morning. Instead of writing a post, we’re going to give away a couple PCBs for an all through-hole version of the USB Infrared Toy. This is part of a kit that probably won’t be made because the through-hole version of the PIC18F2550 is four times the […]
DesignSpark freeware PCB design
We’ve been meaning to check out DesignSpark. Free from practical constraints on board size, pin counts, layers and output types… Multi-page schematic designs are supported…. supports the importing of Eagle design files and libraries… It’s not open source, but it could potentially be a favorable closed-ware alternative to Eagle. Eagles’s board size limits don’t usually […]
Adding custom graphics to PCBs in Eagle
Do you want your next PCB to be pretty? Here’s how to add custom graphics to a PCB using Eagle. Via Make.
Easy vias on homemade double sided PCBs
Double sided home-etched PCBs require a lot of patience and luck. Both sides need to be aligned properly, and via wires have to be soldered between the layers so top and bottom are connected. The usual process for connecting the layers is to insert a small wire in each via hole and solder it. This […]
