1MHz External Active Oscillator driving ATTiny85 Clock
Each week I will grab a random electronic component from the vault and build a circuit - this week I hook up an active crystal oscillator to an ATTINY85 so I can make an OLED display clock.
Each week I will grab a random electronic component from the vault and build a circuit - this week I throw in an LM358 OpAmp and an LM393 comparator to demonstrate hysteresis, the so called Schmitt Trigger.

Each week I will grab a random electronic component from the vault and build a circuit - this week I look at a small collection of things, four very useful, two very useless (except to teach me a lesson).

Each week I will grab a random electronic component from the vault and build a circuit - this week I look at simulating (logic.ly) and then building a regular SR Flip Flop followed by an "ALL NOR" gate version for the win.

This adapter makes prototyping on a standard breadboard easier, as it organises your components on one board for easy access and use. You can solder on any 1206 format components such as resistors and capacitors in any combination. You can even build up mini circuits such as a resistor/LED combination or a low pass filter.
