Build your own garage shelf for under $30.

7 Comments
A garage without storage is a pitiful thing. It gets cluttered, messy, and soon, it becomes impassible. Ive been looking for cheap storage options for my garage, but havent had much luck finding anything (I even googled how to build garage shelving instructions, but didnt readily find anything suitable). Home depot sells storage racks for way more than I would have paid for them…$60 for a 36″ x 18″ 72″ resin flimsy storage rack, and target sells a smaller wire rack for about $40. These didnt seem like suitable options, so I decided to save some cash take the DIY route, and make my own heavy duty storage rack instead.

I wanted my rack/garage shelf to fit the space in my garage just so, so I measured and calculated the figures. I would need ten 2′ x 4′ x 8′ studs to make a rack that was 70″ x 19″ x 72.” I ran to the nearest Home Depot and purchased the studs, and came across some small metal casters…little wheel attachments to make my shelf mobile. These were about $3 each. The total came out to be just shy of $30, and that was fine with me considering I would be saving a lot more if I wanted to buy a heavy duty shelf of this size.

1. First item on the list was to cut the four legs of the shelf to six feet tall.

2. Next I cut the shelf supports (the crossbeams) for which I needed six. These needed to be 66.5″ as the legs of the shelf would add 2.5″ to the width.

3. After, I cut the short links which would connect the front and rear portions of the rack. I wanted my shelf depth to be 19″ so I cut these to 16.5″.

4. After all the cutting was done, I needed to drill the holes to where I wanted my shelving located. I drilled 4 holes, with two holes alloted for the crossbeam, and two for the links. I made three sets of the four holes on each of the legs of the rack. One set for the top, middle, and bottom shelf.

5. Now for the assembly. I assmbled both the front and rear of the racks first, by laying them on the floor and screwing in the crossbeams. I then attached on the front of the rack the links so I could attach the rear portion of the rack to the front portion after. I installed the casters after this was all done.

6. The joints of the rack look like this:

7. Next comes the shelving platform. I didnt buy any plywood or material to use for the shelving. Instead I scrounged around my wood shed and found some 1/4″ board of sorts, and some old pieces of 5/8″ plywood. I had to cut pretty creatively to utilize all the board and cover the shelf platforms.

1/4" board for the upper shelves (where lighter things will be placed)

5/8" platform (where heavy things will be placed)

5/8" plywood (where heavy things will be placed)

8. After finishing my rack, I noticed that I had enough space to add another shelf. I added this one above the middle shelf, and found some messed up 2 x 4′s in the wood shed. They were not in the best shape, but would work for this application. I installed these sideways as the shelf was not going to hold a lot of weight, and would allow more clearance for putting things on the middle shelf.

With extra shelf added.

The shelf took a few hours to build, but the satisfaction of making something and saving money (although with the time trade-off) is to me, definitely worth it. an added bonus are the casters which make my shelf mobile. After piling on the clutter in the garage, it was really convenient to be able to roll the shelf around and into different positions. I also realized that the casters have the extra benefit of keeping the wood off the garage floor where it might someday come into contact with water (washing the garage floor, flooding washing machines, etc.).

I did add one final touch to the shelving, in that I added an eye hook to tie some rope through which connected to the wall. Living right next to the San Andreas faultline, I wouldnt want to find my shelf and all its contents laying on my car after an earthquake. Now for the best part…when my wife pulled into the garage and saw all the clutter neatly organized onto the shelf, she was delighted…and finally realized I could build something that I always say I could for less. Score!

How to replace your address number light with a solar powered LED system

0 Comments
A while ago, I picked up a solar panel from a Volkswagon dealership when my friend purchased a Volkswagon Jetta. On the way out of the dealership, I peered into one of their closets, and saw a bunch of these panels just sitting in boxes and piled on a shelf. The salesman told me they shipped with the new cars for use during transportation so the batteries would not drain out. They hooked up to the OBD sensor port and mounted on the windshield with suction cups and directly charged the battery from there. Pretty cool, and so was the salesman as he gave me and my friend one panel each.
The panel had been sitting around collecting dust till I scored some replacement UPS batteries (smaller 12v sealed lead acid batteries). But the only thing I could think of doing was cutting off the OBD sensor plug from the panel, and wiring it directly to the battery in order to give it a recharge. It was only until I noticed that our address number sign was missing a bulb and was wired to a small transformer above our water heater, did I begin to dream about a better life for the poor, lonely, solar panel.

I work at a computer liquidation company, so finding LEDs was no problem as many computer peripherals, server cases, and the like have these things mounted in/on them. I found three bright white LEDs (I figure they pull about 3.4volts drawing 20 milliamps each after googling), and found an appropriate resistor for use with the system (I used the LED resistance calculator at http://ledcalc.com/), by taking it from an old cisco router powersupply (its actually a 240 ohm resistor and the calculator called for a 100 ohm one, but it doesnt seem to affect it much).  I also upgraded my battery to use my old car battery that died from my car…I just charged it for several days with my solar panel till it was 12.7v.

As illustrated in the diagram, I wired my LEDs in series, attached the resistor to the positive lead on the LED chain and tested it with my battery. It worked!

I then unmounted my address number sign and had to pop out the female plug which the bulb would screw into. That gave me a nice sized hole to thread the LED string through.

In this picture, im using one of the UPS batteries to test it with. Now, I needed to unhook the original wiring which went from the address number sign to the transformer and reroute that with some wire to my car battery/solar panel setup. I went into the garage, and unscrewed the two wires from the transformer.

I then ran some speaker wire that I had laying around to those two wires to act as an extention, and connected it to my car battery.

I then reconnected the wires from the original address number sign out in the front of my house to the string of LEDs I tested earlier. I remounted (two screws) the address number sign, and replaced the hood which fit over the LEDs.

I was pleased that it was still working, and waited till dark. I did have to adjust the direction of the LEDs, as they were extremely bright and would streak a beam of light over only certain parts of the sign making it difficult to read. I ended up taking off the hood, lining the inside with tin foil, and oriented the LEDs towards the center of the sign and pointing towards the hood. The tin foil reflected and diffused the light so it was more evenly dispersed.

Im happy with the results, and the idea that I wont be spending any electricity on powering up a stupid address sign at night. It also makes my house easier to spot as the light from the LED is sort of bluish white, and looks completely different from the other houses in my neighborhood.
