I guess I was watching a bit too much Star Trek with my brother. I decided to make a phaser.
Some of you may know that there are multiple types of phasers. I modeled mine after one of these....
HERE IS A VIDEO, basically this whole instructables.
Step 1: Schematic
And a parts list:
- two NPN transistors
- $1 calculator
- Some resistor
- 1.5v battery and casing
- ATTiny25, 45, 85
- 2x pushbutton
- piezo buzzer
- 3x resistors (one for LED, two pulldown)
- NPN transistor
- LASER BEAMZ
- OPTIONAL - AVR ISP header
The schematic should explain. Attached is the code.
Step 2: Just a Tip on Taking Apart the Calculator
First take the calculator apart. you should be able to find the place where the rubber thing touches the board. Those are two contacts of a switch. Now trace those contacts until you find a spot where you can solder wires to.
You should have four wires after, Vcc, GND, =1, =2.
To find out out where to connect =1 and =2 on the transistor, just test out both ways! It's one or the other.
Step 3: Some Pics of the Phaser
Well, I used an old paper towel roll as the handle, and leftovers from a pin wood derby car as the body.
I cut them to shape, glued them together, and painted them black.
After that I completed the electronics and glued those on too.
