LEAP#265 Doodling on an Oscilloscope
More of my minor obsession with digital potentiometers!
The MCP42010 dual digital potentiometer is pretty nifty. And two channels means it is possible to control
two inputs for an XY plot on an oscilloscope. So time to get drawing!
Of course, the first thing to try is the classic Christmas Tree.

LEAP#264 MCP42010 Digital Pot
More of my minor obsession with digital potentiometers!
This time the dual 10kΩ version of the MCP42010 with SPI control.
I really like this unit - cheap and very flexible. I ended up using it in a few applications. Stay tuned!

LEAP#263 Boldport LigEmDio
A USB-powered LED tester kit featuring a classic BJT constant current source.
Another beautiful board from the Boldport Club - the embossed patterns are truly marvelous.

LEAP#262 Bazz Fuss Chocolate Noisette
The Bazz Fuss is about the simplest distortion circuit I’ve ever seen that in fact yields pleasing results.
After a few experiments comparing configurations on a scope I ended up using two S9013 in Darlington configuration.
The result is decidedly luscious, so the final build went in a suitably sweet chocolate noisette box.
