LEAP#253 ATtiny Programming Shield
I covered programming an ATtiny with the Arduino ISP in the
ProgrammingWithArduinoISP project.
Since I’ve been programming a few more ATtiny processors, and simplify the processing of programming an ATtiny with ArduinoISP, I wired up a strip of protoboard to serve as a custom programming shield.
As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub

LEAP#252 Message Waiting
This is a variation of a bi-polar LED flasher circuit that uses two single LEDs. Since that’s not very interesting, I free-wired it with surface mount components to make a little “message waiting!” indicator. Putting a card in the slot turns on the LED flasher.

LEAP#251 The Lady
A fine specimen of Coccinellidae Boldportus, a new type of ladybird discovered in Bermondsey, London.
“The Lady” is Project #4 from The Boldport Club. It is a really simple circuit, and functionally nothing ground-breaking ..
but that really isn’t the point. It is just a stunning bit of PCB design. Yes, this is more art than electronics!

LEAP#250 AudioDSP Library for the pedalShield UNO
When I built the pedalSHIELD UNO and a clone,
I started collecting my code in an AudioDspDriver class library.
I’m liking the encapsulation and reuse it provides over just hacking sketches based on
the pedalSHIELD examples.
So this project is an exercise in implement the equivalent of all the pedalSHIELD UNO examples.
