Fasten the servo to the inside of the box with double sided tape. Measure the distance from the center of the drive gear to the box. Place little blocks in each corner of the box at the same level of the top of the servo hub. These will serve to hold...
Layout a meter dial using free MeterBasic software from www.tonnesoftware.com. Print the dial on glossy photo paper. Cut a slot for the servo gear drive and place the dial in the box. Make a pointer from a tie-wrap. Cut or file the hub to the same thickness....
Temporarily put a jumper between ground and the input pin on the header under the box. Turn on the system. After a 5 second delay the servo should move to zero then full scale then back to zero. You may have to adjust the mounting of the pointer...
Get yourself a box, and you put that stuff in the box.What I ended up doing here is mounting metal supports to the metal tripod pole. I then used lacing twine and laced the battery to those supports, the plastic bin is basically just sandwiched in there....
Through Hole Technology (THT) versionThis is how I built the Through Hole Technology version Make a double-sided fibre glass PCB (see front- and back- PDF files below). There are several ways to do this. The way I do it is to print the front and back...
Drill two holes in the lower half of theArduino box and fix it to the top of the potentiometer housing. Thread wires through the holes. Add in the Arduino, ethernet shield and breadboard and hook up the parts currently attached to the housing. Open up...
Place the lid close to the bottom and wire everything in, trying to keep the wires short. There is very little clearance at the top of the case so anything attaching to the shield should not have extra height (eg no jumper cables!). After everything...
NaCl Window0NaCl Window and and Mirror – DIY OCWell, I decided to give this a try for the OC of the CO2 laser. A simple gold mirror with a hole in the middle and a salt window. The hole was easy, I simply put a glass drill bit into a battery powered...
After some looking around I got this one for 30 dollars.It was bare, but that is ok. I looked around for a container for it, and could not find one that I liked. I considered building one out of wood, but chose against that as well. One option was to...
After some scrounging around I found a cheap axis laser housing with diode and driver board still intact! For me, this is a mirracle as most of the time, I usually disassemble things when I first get them.After I scrounged up the rest of the parts I...
I borrowed an idea from my friend Mads Hobye for my enclosure. Mads founds these sleek boxes at the container store and used them to make project enclosures for the various musical instruments he's built. These boxes are particularly convenient because...
The starting point for this project was the SparkFun Hatermatic. I bought or already had the items on the Hatermatic wishlist (see links), and went to my local equivalent of Harbor Freight to get a 50 cal ammo box. The eponymous "Craig" works for a military...
Lay out the panel and hole cutouts for the printer, coin receptacle, switches, and if you want, power cord hole. I used a plastic grommet from my junk collection for the wallwart cords.I found the ammo box to be an excellent project case and will be...
