I would suggest putting this project together on a breadboard first and then soldering it up on perfboard if you enjoy it!
Step 1: Do You Have The Parts?
* Small wires for making connections
* Female RCA (TV cable) adapter. I use these for power input on all of my soldered-up projects.
* Female headphone jack (1/8 in. / 3.5mm.)
* Phototransistor. THIS IS NOT AN LED
* 10,000pf ceramic capacitor. #103. This is the same as 0.01uf or 10nf
* 4 different valued resistors. 4.7 Kilohm, 10 Kilohm, 22 Kilohm, and 10 Megohm
* NPN transistor
* 555 timer IC (integrated circuit)
* DIP-8 (dual in-line package - 8) IC socket
****If you don't know where to find these things, head on over to MOUSER.com and search for them! make sure to look at the datasheet of each item before ordering!****
****Note that both the DIP-8 IC socket and the female RCA adapter plug are unnecessary for building this project on a breadboard.
Step 2: These are NOT LED's!
These are PHOTOTRANSISTORS.
Don't mistake these for LEDs. They look essentially identical, but they work in the opposite fashion.
LED's emit light, whereas phototransistors absorb light to control the flow of electricity.
The phototransistor is what makes our Tight Light Theremin work! Tightly!
