Online PCB routing software
Kelvin writes: I was designing PCB using Kicad recently. For slightly more complex board, I was lazy to route them and instead use the in-built autoroute feature. Kicad autoroute feature seems inadequate. This is when I found the free autorouting tool at FreeRouting.net To use the tool, one needs to export the PCB design to […]

3D printable PCB stand-offs
We recently ran across another 3D printable PCB accessory on Thingiverse. This time it is a stand-off that slips on the edge of a PCB and the edge of a piece of plywood. This is a quick way to mount your PCB on the side of a project or into a project enclosure.
Tutorials for KiCad
KiCad is an open source PCB layout program. It’s not as well loved as Eagle, but there’s no restrictions on board size. Curiousinventor’s KiCad tutorial covers many of the common issues new users will encounter. Thanks Kelvin! Via the tips line.
Quirks of PCB manufacturing at ITead
Itead posts a reaction to EEVblog’s list of PCB manufacturing quirks: Now we remake the boards again with the same gerber file. Today the boards return, we can not wait to start checking the board, and the result make us very disappointed – the factory seems change the gerber again and the boards still not […]
Easy toner transfer PCBs with hacked laminator
When you make PCBs with the toner transfer method, you have to spend around 10 minutes per board sweating over a hot clothes iron while the toner melts to the PCB. Ahmad Tabbouch though a laminator might be an easier solution, but the default temperature is too low. This tutorial shows how to hack a […]
Flexible PCB, self-adhesive, component adapters
Protoflex is a set of flexible circuit board stickers for SMD development. Peel off a footprint, stick it on 0.1″ protoboard, and solder surface mount parts directly on the sticker. Brilliant use of flexible PCBs. Thanks Kelvin! Via contact form.
Quirks of PCB manufacturing at ITead
Flemming has a list of tips for PCB manufacturing at ITead. Seeed Studio uses the same PCB shop, so these tips apply to their Fusion board service too. I do all my PCB production at ITead Studio the price is low and their published specs are nice, but there are some quirks that you need […]
27C3: File – Print – Electronics
In this presentation from the 27C3 conference held recently in Berlin, Germany, Jeff Gough demonstrates the next step in hardware development, the circuit board printer. As an alternative to dependence on prefab dev boards and kits, Jeff outlines his efforts in reverse engineering an Epson inkjet printer to build a rapid prototyping machine for circuit […]

SparkFun BatchPCB marketplace
MichaelZ tipped us to BatchPCB: SparkFun BatchPCB Marketplace has some interesting boards for sale. Most of them are undocumented but some have some sort link to more info. Thanks McZ! Via the forum.
74F138 Xmas demo
First of all Merry Xmas to everyone! We found some time to whip up a new demo to show the Digital IO mode (DIO) of the Bus Pirate. This mode gives us full control of the pins and acts much like the binary mode. We used it to interface a 74F138 and a couple of LEDs. The 74F138 is a […]
