Hey kiani I see you just taken a whole load of your circuits offline (they were informative so don't know why?). I need to ask you a favour and please bring your circuit 'IRF740 charge Q. Measurements' back online if possible. On it there was a question I had put to our 'most popular user' and was waiting for his reply, if you know what I mean ;)
This is just the same circuit as previous:

But the 7segment are now wired like this for a different effect:
64
16 32
8
2 4
1
Thought its worthy of a repost cos the letters effect looks nicer :P
