So, I’ve been trying to build a Polywhatsit effects processor from the December 2001 issue of EPE Magazine. I ordered the PCB’s from the magazine’s US website, sourced all of the parts (even the weird one), bought a new USB PIC programmer board on eBay, and started looking at unique housings. Flash forward two weeks: [...]

Well, not exactly a datasheet, but I did find some interesting information about the Panasonic EVQ-WTEF2515B encoder currently listed at Electronic Goldmine. I scoured the web looking for data on this item and finally found it in an old Digikey catalog. Digikey was kind enough to publish data about the encoder in their catalog and [...]

Would you pay $30.24 for this part? I don’t want to, but since the only place I can find it is RS Electronics in the UK and I need it to build the Polywhatsit, I might have to bite the Euro-vs-US Dollar bullet and spend money I don’t want to. Where did $30.24 come from [...]

Well, most of the parts for the Polywhatsit are a breeze to source with the exception of one: the 8-position BCD rotary switch. The originally specified part is a weird one. I’ve only found one supplier who lists the exact part and they are in the UK. If anyone is curious, here is a link [...]

I was browsing through some old copies of EPE Magazine and came across a project from December 2001 called the PIC Polywhatsit. It is a PIC-based effects processor that offers some interesting sound effects such as Pitch Multiplying and Reverse Tracking. EPE still has the circuit boards (one for analog and one for digital) available [...]
