LEAP#266 The BoldportClub Cuttle

The Cuttle is a bare-bones Arduino-compatible kit from The Boldport Club. But not just any clone .. this must be the best looking board I have! I now have three of them for prototyping with style;-) As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub hero_image

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! As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub hero_image

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. As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub hero_image
