Hey guys
I want to make one of these:
http://www.thinkgeek.com/gadgets/electronic/79be/
any ideas on how it can be done, i guess i can get all the bits from RS but what would I need, could it be done with a 555 timer or a simple pic chip and a speaker?
***********EDIT************
I have found this
**broken link removed**
This would surly do exactly the same as the circuit available? simply by changing R1 and R2 and the capacitor?
Thanks
