Each week I will grab a random electronic component from the vault and build a circuit - this week I finally have a CD4026 working, although thanks to the "wrong" 7 segment display I need to invert all outputs to make sense of the resulting signals. A CD4069 from a previous blog plus a transistor NOT gate do the trick.

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.
