FPGA Oscillator

This has turned up from WaveShare. It is really very reasonable as I don't think that I can buy the FPGA device for that. I plan to bash out a something themed on the ShapeShifter. It won't be as sophisticated (or any where near as expensive). I always enjoyed a bit of VHDL coding but the requirement for it is sadly thin on the ground these days. I was a bit surprised that Cyclonix really just bolt an Altera evaluation board onto a bunch of DAC/ADC and analog interface device on a panel. From the reading I have done, they use the NIOS soft processor -- I was going to skip that bit and stick an ARM in beside the FPGA as the compiler/debugging is generally a bit ropey on an environment with such a small user base. That will leave more space for Audio processing and waste less resources on the FPGA.

From the Verge

When Walking to work recently I discovered quite a nice Audio Generator in the yearly rubbish collection beside the reoad. I had to replace a binding post and put a new power plug on it but it seems to work nicely enough...
Later in the week I found a fairly old Yamaha Electone B-4BR. So as not incur the wrath of the wife it mostly stayed there except for the reveb spring...
