Flashing Joule thieves finished

I've (almost)built seven flashing Joule Thieves and two regular ones in the past weeks.They are a mixed bunch :one is a robot,two are bare bones,three are boxed up and the last one will also be boxed up.One of them is rather special I think: it has four capacitors with two switches so I can change the flash rate.All of them have green LEDs(to honour the month of Ramadan in which they were built).
Now that I have finished those it is time for my next project which is remaking or changing some of my Pummers and Magbot pendulums some of which don't work very well or at all.
