Finishing the solar powered thermometer (-40 ... +99.9°C) with supercapacitors. Talking about prototyping boards, putting it into a plastic box, showing some supercapacitor calculations, ice bath temperature sensor test, waterproofing it for outdoor temperature measurement. And most importantly, no Arduino, no hot melt glue, no Li-ion battery and only 1 zip tie used!
