I do a lot of projects with Arduino's and breadboards. Often as I work on a messy workbench, the Arduino or breadboard get jostled and the wires pop out of the headers or the breadboard. To solve this problem, I decided to make a simple acrylic stand for mounting an Arduino and a breadboard that would prevent them from moving around.
I used a laser cutter to cut the acrylic to size, to cut the holes for mounting the Arduino and to engrave a rectangle on the base to help align the breadboard. Don't despair if you don't have access to a laser cutter: you could use a saw to cut the acrylic and a drill press to drill the holes.
There are two versions of the stands: one for the Arduino Duemilanove and Diecimila and one for the Arduino Uno.
The photos show two views of an Uno stand made out of clear acrylic and a Duemilanova stand made out of blue acrylic
I made this at TechShop in Menlo Park.
Step 1: Parts
- One 1/4" acrylic sheet (color of your choice) at least 4.5" x 6.5" (the stand when cut out is 3.8" x 5.7")
- Four 19mm vinyl bumpers (available at any hardware store)
- One mini breadboard (approx 3.3" x 2.2") (Radio Shack 276-003 or Jameco #20601 or similar)
- Three 1/4" #6 nylon spacers
- One M2 x 20 machine screw
- One M2 hex nut
- One M2 washer
- Two M3 x 20 machine screws (you can substitute #4-40 x 3/4" machine screws)
- Two M3 hex nuts (or #4-40 hex nut if you use the the #4-40 screw)
- Two M3 or M4 washers (or #4-40 washer if you use the #4-40 screw)
- Three or four 1/4" #6 nylon spacers
- Three or four M3 x 20 machine screws (you can substitute #4-40 x 3/4" machine screws)
- Three or four M3 hex nuts (or #4-40 hex nut if you use the the #4-40 screw)
- Three or four M3 or M4 washers (or #4-40 washer if you use the #4-40 screw)
Step 2: Cut Out the Stand
I used a 45 watt Epilog Helix laser cutter and used the following settings for the laser. You may need to use different settings depending on what model laser cutter you use.
- Raster: Speed 50, Power 80
- Vector: Speed 6, Power 90, Frequency 5000
Step 3: Assemble the Stand
- Assemble each of the machine screws as shown in the first diagram. For Arduino Duemilanove's and Diecimila's use the M2 screw for the smaller hole. Don't over tighten the screws.
- Remove the self adhesive from the back of the mini breadboard and use the engraved lines as a guide to adhere to the acrylic stand. If your breadboard doesn't have self adhesive on the back you can use double faced tape to mount it. Using the engraved lines will ensure you get the board on straight.
- Turn the stand over and stick the vinyl bumpers on the back as shown in the second and third photos. If you use clear acrylic, like I did for the Uno, make sure to place the bumpers under the Arduino circuit board and under where the breadboard goes so you don't see the bumpers from the top of the stand.
Voila! You now have a sturdy prototyping stand for your Arduino projects.
Go forth and make cool stuff!
