Hi All,
I've been breadboarding basic 555 timer circuits, experimenting with different component values. I found a set that gave a decent hz rate for the LED.
R1= 1kohms, R2= 10kohms, R3= 120ohms, C1=100uf, 9V.
I don't have perfboard and I wanted to practice my soldering skills for BEAM projects that I want to try out down the line. I decided to freeform the circuit, soldering components to the 555 timer.
Please take a look at the photo. I know the soldering is sloppy and it is really ugly. I used a metal paperclip as rails for ground and + voltage.
For some reason, the LED lights up, but it does not blink. I've swapped capacitors several times, testing them on the breadboard afterward, and the components seem to be working. I've also taken a second look at solder joints, desoldered, and reheated with a fresh coat of solder. Could the IC be fried from all of the soldering and heat?
Any suggestions would be great!
Thanks!
