This project evolved out of an old weak stepper motor that I had laying around. I first tried to create a robotic arm with the stepper motor. The motor was barely able to lift the arm, let alone an external load.Then I tried to build a 3d printer with the stepper. Clearly I wasn’t thinking straight – the stepper couldn’t lift thermocol and I wanted it to print objects in 3D. Not too smart.
The end of this project was to attach the stepper to an ATMega328 with a ULN2003 darlington array and just keep making it spin around. I used the stock stepper code on the arduino website and used my Leonardo to program the ATMega. The only use I found for it was to create a panaroma capture device. However, as whimsical as it might sound, it genuinely does take better photos than a handheld device. Enjoy!
My first woodworking post here! And its actually something I made quite a while back, but never really got around posting plans for. This is a really simple custom table lamp you can make in very little time and also one which doubles up as a USB charger. The only power tool you’ll need is a drill!
1/2″ wood – 30″ x 5″ (You won’t get wood this size, but this is all the half inch ply you need for this project)
1/4″ wood – 10″ x 5″ (The same for this as well, you can use scrap wood if you have some laying around)
A USB charger
A bulb holder
A small LED bulb
Female and male AC plug
Cut 3 pieces of 10″ x 5″ wood (two from the half inch and one from the quarter inch)
Like the template below, draw up a scaled version of of the text and place holes in roughly the positions of the text. The holes shouldn’t be too close, otherwise the drill bit will keep slipping into the adjacent hole (unless you have a drill press, which I don’t). It doesn’t matter if the text doesn’t look readable, it was the same for me, but it takes shape better in the wood.
On the piece of 1/4″ plywood, make a hole roughly the size of a usb port. Use a cable to measure it out.
For the side pieces, cut out 5″x5″ pieces of 1/2″ plywood.
Now, mount the bulb holder on one of the side pieces. Make sure you mount it at the centre of the piece so that the top piece can fit on well.
Now, mount the usb device so that it is aligned with the hole made previously. In case your charger has a curved edge (like mine did), find a corner to mount the usb charger. Then use a USB female connector to extend the charging port.
Finally, wire up the AC plug to the bulb and use the female AC plug to the USB charger.
Glue the entire thing in place! This is the boring part – waiting for that glue to dry so that you can look at your beautiful creation.
After its dried, I suggest you use a stain to make the plywood look nice. I used paint, and it just hides the grain of the wood completely.
