What you will need:
No. 2 Phillips Screwdriver
Vacuum Desoldering Tool (Not strictly necessary, but incredibly helpful)
47 uF/16V Electrolytic Capacitor (QTY: 2)
*Note: These can be rated for higher than 16V. The originals are 16V, but a higher voltage rating (25V, 35V) is fine. However, these MUST BE 47uF so that the timer delay (RC Timer
) in the timer circuit is preserved. These can be purchased at RadioShack.
Something that can give you at least 12V (2 9V batteries, One 12V Battery, 12V Power Supply, etc.)
