    I just spent the last 40 minutes building that, but the main problem i had was, the 555 requires > 5volts to run and the CMOS chip requires 1.5 - 3v max, so I had to add a Voltage Regulator so it took a lot longer than expected.

    Meanwhile i'm annoying the crap out of everyone in the house with this thing lol

    Do what I did, build it semi permanent and give it to a 5 year old! Then deny, deny, deny!
