HARDWARE DEFINED SOFTWARE
My FUNcube Dongle Pro arrived today (via FedEx). Ingenious tool, the first tests after the firmware upgrade were very promising; even with the “universal”-antenna which I ‘stole’ from my trusty Yaesu VX-3E… 😉 Using windows, the usage of the ‘FCD’ is easy. Even though I am able to change frequency under Linux, it is a matter of demodulation software there. More about working with the FCD hopefully soon, now some exclusive images… 😉

Some of you might remember my little Tweet on Nov. 16. about the PCB layout being ready for production. The pic isn’t actually the file I sent out for production; mainly because I found this bug… So *surprise* the finished PCBs arrived; all 10 (I acutally got 11) were $29.90 shipped (to germany – I think I love you, ITead…)… (click for bigger image) Beauty, aren’t they?! – so I got down into my lab and… Har! Beauty 🙂 So. What is this anyway? CNCc is a CNC peripheral controller using an Atmel AtMega644 clocked at 20MHz and connected to the PC via USB (FT232). Features: USB 2.0 to serial using FT232 3x 10A / 250V Relais

Read moreFor a little nightflight-illumination-project I needed a small 12V DC-to-DC step up converter. I searched and found one on ebay for about $13 including shipping. Not that bad a price, considering the shipping from the USA, but looking at Wikipedia, it turns out, that these devices are in fact dead simple. So:Â Tiny25 + transistor + diode + inductor + elkos = step-up-converter. But, having a tiny on the board you can do some fancy stuff. Here is my design; 40mm x 27mm with regulated and adjustable output voltage, STABLE-output or ENABLE-input and I2C interface. I’ll supply the design files as soon as there is source code and it turns out the baby actually works. Please note that the PCB Design and schematic are released under a CC-BY-3.0 license.
