Third Project: Creating a Sound Circuit

After reading the schematic, the necessary components were gathered. Unfortunately for me there were no 100K left to complete my circuit, so I improvised. I at first considered using a combination of a 15K and 82K resistors, but in the end I just used 120K resistors. I also redrew the schematic to make a more realistic representation of the terminals of the 555 timer.

After receiving a copper plate, I made an outline of where I wanted to manually etch the circuit paths.

Due to the dremel at the Interaction Station repeatedly losing power, I went to the woodshop and used a drill to etch the rest of the plate.

Soldering with the original 555 timer provide to be quite difficult, so I replaced it with a larger 555 timer that was easier to handle.

Final Project: Personal Circuit

––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––

Awhile back, I saw a video on Youtube of someone chemically etching their water with vinegar and a few batteries. I was amazed by this, and still am. I intend to recreate this chemical etching circuit, and somewhat tweak it to be more efficient if I can.

For my final exhibit, I formed a group with Tiffany Wederfoot, who is working on creating a personal tattoo gun. Since both of our projects are based on DIY / creating tools, we decided that the title of our group should be along the lines of Recreating Tools or Re:Tools.
