CS 555

I found a fitting frame at IKEA. With the original passe-partout and a grey background, the CS 555 is now ready for presentation. I drilled holes for the legs through the base and fixed them with hot glue. Now a can run it from outside using alligator clips.

Also with a schematic for a test circuit on the back side.

Now I consider this project finished.

This still needs to be done. I need some nice board to mount it upon. Maybe some medium dark wood to replace the scrap board that I used as jig.

I set up the necessary "external" components to run "blink.c". ;-)

Success!

Then I drilled holes for the "pins" into the piece of wood, connected the circuit to the pins and added the top plane.

I soldered the ground plane separately. To join it with the "circuit" I added some spacers to the jig. I nailed the jig to a piece of wood because it was slightly warped.

To get all the transistors somehow nice and straight and to make life easier, I printed a jig for the transistors and started soldering:

Having the three layers in mind I started planning how to design the circuit that it roughly follows the block diagram:
