I have made another batch of the LivingColors Arduino (Genduino ?) shield. The PCB’s are by DirtyPCBs.
I made an adapter board so i can use different CC2500 modules without having to change the boards.
Drop a line in the comments if you want one.
Stuff I design and build and take apart
Designing, making and having PCB’s made.

A while ago i made a popular post about having cheap PCB’s made. Some things have changed so it’s time for a new post.
BatchPCB is now OSH Park.
EuroCircuits have broadened their range of services to better cater to prototype runs and hobbyists.
Seeedstudio have a PCB prototype service.
Where there are lots of suppliers and customers shopping for the best price, sooner or later someone is going to set up a price comparison site like : PCBShopper.
The most interesting manufacturer for me is now DirtyPCBs (from the people behind Dangerous Prototypes who made the Bus Pirate), my last 3 batches were ordered there.
The first batch was a new run of the LivingColors Arduino shield.
The second batch was a breakout board for the NiceRF SX1276 LoRa module. Here i experimented a little with contour routing.
The third batch was an adapter board to use no-name CC2500 modules in boards designed for the Quasar QFM-TRX1-24G. The boards are small (about 20 mm x 25 mm) and the minimal size for dirtypcbs PCB’s is 100 mm x 100 mm. Here I experimented with breakout panels, putting 4 PCB’s in one design.
The end result worked out nicely, two things I’d do better now are :
As seen on the stand of the dutch electronics forum Circuitsonline at the VERON Fleamarket : a home built modular synthesizer.
It’s hard to find more information, all i have found is the forum post (in dutch : translation here).
The setup is similar to the Elektor Formant and Compact and the modules from Doepfer. Of course those are all inspired by the Modular Moogs.
The use of PCB as frontpanel is innovative. It’s a clever solution: PCB can be made cheaply and easily, in all sorts of colors and with text. Mikes electric stuff explains how and why.
I hope to find more information about this machine, a kit like this needs to be heard as much as seen.
Quasar UK have changed their 2.4 GHz module.
The pinout is the same but it is now a SMD device.
No need to change the layout. The crystal is thu-hole so there are solder bumps on the back.
The different iterations of the shields..
Clockwise from top left, the V05 shield with socketed module, the original protoype, the V06 shield new with new CC2500 module and the V05 shield with external antenna.
