The circus of the sub-projects continues !

I couldn't wait to complete this project and #ScoPower was hacked in one hour. So why bother anymore ?

Well, ScoPower led to #Active scope probe with no dedicated power supply and at one point I'll have to check the frequency response, so I need a frequency generator that is able to sweep though low and high frequencies.

There is a problem, though : this frequency generator can only output a square wave, up to 40MHz.

Now I have different solutions:

• get a DDS module (Nooelec has one for 15$)
• Use a FPGA to do the DDS thing, my Actel chips can go pretty high if well designed, and I can learn to control the PLL. There would be a 8-bit output (representing a sine stored in blockram) going to a fast/video DAC
• Do it the hard way with discrete parts (but it would not have the same performance)
