You're Best DIY Project Thread

Show off your best DIY project! Or link to ones that you would like to try. Or anything like that.

Feel free to blow your own horn and what not, I want to see some cool stuff (does not have to be bicycle related, though I guess that is preferred.)

I do most projects myself, whether it be residential or commercial repairs/building with work, or fixing my own car. Can't really pick a favorite.

I built my own headlights for my bike - it was kind of a mix of a few plans I had seen. Did some research on battery drain times so that I could have a three hour run time of 2 - 20W halogen bulbs at 30 degree below. Man a 12V, 7.2ah battery is really heavy!!! ( carried it on my rear rack).

I'm thinking of building this bike light next:

I also built a spiked tire for winter riding. Used sheet metal screws on the side knobs, and an old tube as a liner. Works awesome, better than any 'studded' tire i can find. Drawbacks - I have to install the tire wearing gloves so I don't stab myself, and the spikes can get caught on things. I'll see if I can find the link for the plans.

Oh, where do I start?

My CNC conversion for my milling machine is probably the pinnacle of my DIY career.

I gutted my bathroom to the studs 2 years ago. It took 1 year for me to remodel it mostly by myself. 1 year since I finished it and I am barely getting the desire to do anything else.
Redoing a bathroom involves tiling, plumbing, dry wall, carpentry, electrical know how, and a few other disciplines. I now know why many folks pay someone else to do it for them.

Wire Game

I made a sprial wire carnival game from a barbeque motor, vacuum cleaner belt, phone untangler (for the rotating electrical connection), a turnbuckle, some nail punches, a key ring, some speaker wire, some big wire, some sanding drums, and a bunch of junk from Radio Shack. To play it, the spiral rotates away from you at about 5 rpm and you chase down the spiral with the wand/keyring without touching the spiral (red light and buzzer if you touch). To win, you have to get past the spiral and touch the chrom cup at the bottom (green light and bell goes off). Just finishing up with chroming the wire and gluing the box together.

These were a giant step for me, but a small step for mankind.

The timer on our old oven quit. A replacement was not available. At Radio Shack I got a digital timer that runs off of a AA battery, but switches 120 volts AC. I plugged a 120 volt AC to 12 volt DC timer to it and plugged it into the timer. I ran clear speaker wire under the cabinets to the built-in oven. The speaker wire connected to a 12 volt relay capable of switching 250 volts. The oven has a new timer. We saved about $1500 because we did not need to install a new oven and countertop burner set. (You cannot one without the other, or so my wife says.) The new timer is accurate to the minute.

We have a flashing LED from Radio Shack to tell everyone when another phone is in use in the house. It runs off of a 9 volt battery and goes through batteries too rapidly. I replaced it with a nickel-cadmium rechargeable battery and connected a wire to the power supply from the phone machine. I added resistors in-line with the wire to reduce the current flow to 1/100th of the ampere hours rating of the battery so it is always charged, but never over-charged. We have not replaced that battery in over three years.

I wanted a Xenon tube power timing light for tuning my car engine. I borrowed an AC power timing light from a friend to use. While I had it, I opened it and made a diagram of the rather simple circuit. I went to an electronics shop and bought the components. I built it and put it in a wood case I made. It works very well. At the time the gophers often left mounds in our yard that dried very hard in the sun. When the lawnmower blade hit the mounds the engine stopped abruptly. Frequently it stopped so hard that the flywheel partially sheared the soft key to the shaft. That changed the spark timing so that the engine might not start. I filed notches in the engine shroud and the flywheel cover. I could connect my timing light to see if the engine was still in time and without going through several steps to remove shrouds and check the flywheel key.

For my bicycle I have made a torque wrench from a bar of steel and a fisherman's scale. I ground an 8" adjustable wrench down to 2.5 mm thickness to use as an infinitely adjustable cone wrench. I made a headlamp from a 3 LED set for a two AA cell Maglite flashlight and a battery holder from Radio Shack.

I wasn't the only one to work on it, but I restored a GT40. Sorry for the pics, they are from scanned photos, I did this a long time ago.

A friend and I rebuilt a 63 Chevy II Nova from the frame up. Took us two years to do it. Took him a month and a half to crash and total it.

I think that's really cool, but I have to ask: of all the things in the world that you could have built, what inspired you to make that thing? Did you plan on using it at a carnival? Did you see one and think, "hey, I can do that"?

I'll have to see if I can dig up pics of my college senior project when I get home. Me and a partner built a small electronic car, powered by a Motorola MHC11 microcontroller with embedded code. The uC was connected via DIO ports to infrared sensors which were placed on bottom of car frame in front. The programming was such that it would read the input from the sensors and keep the car following a black line on a light colored floor.

It was spec'd after one of the IEEE contest cars from a few years previous. We used their contest requirements as your design goals.

Yep, that's it. I saw one at an amusement park, and it had the appearance of one of the few games of skill instead of a game of chance. Since I didn't want to pay $500 ($2 at a try, three for $5) to learn how to do it, I concluded I should go make my own. So I figure by this time next year I'll be able to impress my friends and family by winning on the first try, and then I'll get to walk around the park all day carrying this stuffed toy that's bigger than me. Of course, I now live 600 miles away from the park where I saw the game, but they have to be everywhere, right?

It took a long time to design my home version (thinking of cheap or free components) and build, but I'm almost done. I find some satisfaction in small projects all the time anyhow, here are a few more . . . Austin Healey 3 liter engine, battery box for my bike, UPS for my basement water pumps, 10 foot diagonal front projection movie screen . . .

It's not much but I built a hard tonneau cover for my new pickup back in the late 80's before they became all the rage. It looked pretty sweet and was very functional.

I've also built two trailers. One 5'x8' utility trailer and a 16' flatbed car trailer. I sold the car trailer last year for about three times what I had in it...minus the labor. I worked on building it all one winter....with no heat in my shop. I was sick more than I was well that entire winter.

THIS PIC shows both the cover and the car trailer I built.


One DIY project I will never attempt again is replacing all the windows in our house. That certainly did suck arse.

That's cool. I'm sure they are at pretty much anywhere. I've also seen one that looks like two parallel coils on an even horizontal plane. With this one, you have one vertical rod that you navigate in between the two coils to reach the center. I tried it once, with no success. The only reason I ended up doing it myself was because I saw the girl that ran the thing do it and she made it look so easy

When I was a wee lad in the mid-1950's someone marketed a hot dog cooker that was little more than nails connected to a 115 volt cord. Of course it was enclosed for safety. It cooked half-a-dozen wieners at one time. It worked, but the hot dogs smelled a little like burnt houseflies while cooking. Leaving them "on" too long was not a good idea. We used it only a short time before sending it to that great refuse bin in the sky.
