I bought an AD9833 DDS module from China – you know the one:
I wanted to control it from an Atmel ATtiny and my weapon of choice was the ATtiny44. Now I could just have easily used an ATtiny2313 (both devices are 14-pin), but I didn’t – and I went on and built a […]
We don’t do much SMD (surface mounted) work here at Stompville. When it comes to the True Bypass Relay however, smaller may just be better, so we designed and built a surface-mount version to see how small we can realistically make it – and the answer is about 30% smaller.
That is 30% […]
I’ve been looking at using an encoder as a front panel control. Encoders are industry standard devices made by ALPS, Panasonic, Bourns and CTS among others. They come with and without a push-button switch and (not-counting the switch) have three terminals, labelled A, B and C.
We can connect the C terminal […]
I came across Ian Johnston’s project to modify a Pioneer surround amp to incorporate a motorised volume control and decided to use his design as the basis for a small project. For his part, Ian hacked his design from parts he had available, whereas my design is fully realised and value engineered. […]
UPDATE 8th May 2012: I have now posted a library for the AXE133Y on the Arduino website
I bought the AXE133Y from the Picaxe store. It’s an inexpensive and easy to assemble kit which gives you a serial-controlled 16 x 2 dot-matrix OLED display. I wanted to connect it […]
