This is the finished circuit on veroboard – just plug in the audio cable to the jack, and clip on the battery and it will work fine! I extended the photoresistor with some more cable and heatshrink tubing to give us more reach and the ability to position it a bit better.
There’s two sitting in Andreas’ locker to use, I finished them off a bit with some bits of a plastic lid and lots of tape to protect the circuit. Raz said they look like triffids. They definitely do now….
Thanks for a great session today I’m getting very excited about all this…
