This is an Instructable to make a very low tech timer switch. mine goes off once every 12 hours for about 3 minutes. I made this because i not really that good with electronics but still wanted a cheap timer. This is just the prototype and i hope to make a much more permanent one when i have the time, the plan is to use it to automatically turn on my solar powered irrigation system in my greenhouse. That might be my next instructable.
Oh and by the way, this is my first instructable so any comments would be welcome.
Step 1: Tools and Parts.
The tools and parts I used where what I had lying around. This made this project free and also green as i recycled some parts
soldering iron holder
solder sucky thing (don't know what its called)
multi-meter (although i don't actually think i used it but thought i might so took a photo of it)
Paddle lever switch or something similar
c.d. or d.v.d
motor or LED
Step 2: Remove the switch from circuit
The idea of this timer is for the hour hand of the clock to hit the switch as it passes and completes the circuit. The switch i used was from an old cd player. This meant i had to take it off the circuit board. To do this i heated up the solder with an soldering iron and sucked it away with the sucking tool. The the switch would just fall out. After i got the switch out i then sanded a tiny aounf off one of the corners.
