True Bypass Relay SMD

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% smaller on… Read More »

Using encoders with Arduino

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 to +Vcc or… Read More »

H-bridge motorised volume control

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.  My main goal… Read More »
