Each week I will grab a random electronic component from the vault and build a circuit - this week I respond to a self-challenge (?) to light multiple LEDs from only four pins on an ATTiny13.
Each week I will grab a random electronic component from the vault and build a circuit - this week I look at the oversize AVR ATmega128A, an amazing package that could be the one chip to rule them all.

Each week I will grab a random electronic component from the vault and build a circuit - this week I transform a DIP8 adapter so that I can use the pesky padauk chip (PFS-154) on an existing AVR based project - and it works!

Each week I will grab a random electronic component from the vault and build a circuit - this week I take delivery of a selection of parts, most of which are for projects involving rechargeable batteries, or solder re-flow platforms (18650 and NiMH)

Each week I will grab a random electronic component from the vault and build a circuit - this week I look at updating an old "perpetual light" QX5252 project with a new PCB and hopefully better hot glue skills.

Each week I will grab a random electronic component from the vault and build a circuit - this week I use my favourite IC, the attiny13, to make a "clap switch", activating an LED with sound.
