About a week ago, I got an email from a friend of a friend, with a couple of ideas for new pedals. The first, less exciting one, was an standard A/B looper, but where, instead of a switch to change between A and B, the switch would be used to swap the order, so you could have A running into B, or B running into A. This seemed like quite a cool idea, and with not much searching, I found a schematic for it over at Beavis Audio, job done.
The next idea was more exciting. Another A/B Looper, but one where the loops are turned on and off alternately via a tremolo type circuit, and with the possible option of an expression pedal to replace the tremolo. This one's still only partially made on the breadboard, but I have got 2 LEDs flashing alternately, with rate, depth and speed controls, so it's all looking good!

I've been pretty busy with other stuff the last few weeks, so haven't been able to do any pedal building, but I got some time this week, so made a friend a ZVex Machine clone. I'd promised it to him a while ago, and it was a circuit that I'd been looking for an excuse to build anyway. After sorting out some issues with it grounding on the box, it works pretty well, and, despite the lack of finish, i think it looks quite cool too.
