Keychain

KeychainWhen I was doing my CFL Teardown I mentioned that I thought the PCB would make a cool keychain. It does. I have had it on my keys for a little while now and it works quite well at helping me find my keys without getting in the way. I like the side with the components silkscreened on, most people like the green side with the traces.
keychainTo make it work as a keychain I had to widen out one of the holes to fit the key ring through. There are a ton of ways to do this, but I happened to have my Yankee Drill sitting on my counter as I was working, so I used that. Next I wanted to take off the excess solder so all the holes would be visible. I was feeling lazy so instead of using a solder sucker I just used solder wick. Once I was happy with the amount of solder I had left I put the keychain in my toaster oven to round off any sharp bits of solder that were left over. This made the board a bit discolored, but it also kept me from cutting myself when pulling my keys from my pocket.

After a few weeks using it the only problem I see is that I am slowly wearing the hole larger. I figure that in a few months I will wear completely through. I could cover the whole thing in a clear epoxy and it would probably last much longer. Probably I will just take apart another broken CFL and use the PCB again.

Yankee Tools

At work I found a hand push drill from Yankee Handyman. Unfortunately it was missing all but one drill bit, and it was bent and broken. I decided that I had to have one. I went to Rockler with my Grandpa looking for one, and it turned out that they haven’t been made for a long time.
When we got back to the house my Grandpa took me out to the garage and to one of his older toolboxes. He pulled out a Yankee Handyman drill, with four bits still stored in the handle.

This beauty belonged to my great grand father. Both it and the drill from work were dirty and slightly rusty. So I decided to clean and oil them. First up was the work driver.
All it took to dissasemble the driver was unscrewing the threaded bit at the front of the handle. As you can see there was a spring inside and below that a wooden peg that the whole thing spins on. It was all covered in dirty oil so first I cleaned all of the grime off with rubbing alcohol and q-tips.
Next up I oiled all of the moving parts and threads, as well as the bit since it was bare metal and a little rusty.
One neat thing about this drill is the bit storage area. Too bad I don’t have any bits to fill the other slots.
The threads on this driver only go in one direction. When you push it in the bit spins clockwise, on the way back out the bit spins counterclockwise. This probably explains the unique design of the drill bit.
Next up was cleaning my driver.
The shaft of this driver has threads in both directions. It can spin in either direction.
The driver had an amazing mechanism to allow it to spin in one direction, and then release freely in the other.

As you can see there was quite a bit of grime on the inside, and rust on the bits.
Getting inside this one was much harder. First I unscrewed the front like the other driver. Then I had to push in the switch on the ratcheting mechanism and slide down the silver cover. This got me into the ratchet. After removing three bits of metal the gears were loose. Next I had to unscrew the back, and then another bit that it screwed into. Even still I wasn’t able to get the shaft out completely.
After a thorough cleaning and oiling both drivers look much nicer, and work better as well. It is much easier to get the bits in and out. With the gunk and rust cleaned off these fine tools are ready for many more years of use.
