Step 1: Materials
-A piece of paper
-A flux pen
-A 555 IC timer
-A 330ohm resistor
-A bc548 transistor (any NPN transistor will work)
-An IR LED
-2x 680nF capacitors
-A 5k pot
-An 1k resistor
Step 2: The 555 IC timer
All the components are preferably flat, or in smd package, so i had to bend the 555 leads.
Once done, i cutted the tape and made the circuit, i had to think it carefully and it was the hardest part.
Step 3: The tape circuit
The flat IR LED you can see in the first pics was not bright enough, so i changed it for a 5mm one.
Step 4: Soldering the traces
I had some tab wire left from a solar panel and a flux pen. I tried them and i realized that is was the best choice.
I applied flux to all the joints and soldered a small piece of tab wire i each one. The result is marvelous but is enough for me.
Step 5: Soldring the components
As you can see, i changed the IR LED because it was not bright enough, and i didn't use the second 330ohm resistor, but i left it soldered in the circuit.
