PCB Rig on Rails by sketchpunk
by Thingiverse
Last crawled date: 3 years, 1 month ago
Awhile ago I started messing around with arduino and I made a testing rig with one camera articulated arm to hold my prop while i wire it up to the breadboard. It worked out well but now Im getting ready to start doing a little soldering which lead me to look up third hand/helping hand type things on amazon.
Didn't like what I saw, then look at thingiverse for ideas and found lots of great projects that inspired me to making something for myself. I really wanted to play around with rails to see how well they work and this was a good project to try it out.
So here is my evolved Arduino testing rig, now its a full on pcb work station. Using 1/4 inch rods (really wish there was metric rods at homedepot) i created rails that can be connect together easily. So i can make my rig any size I want. I went for 12x6 inch design since its a good size for me, but I can always buy more rods and just make it bigger down the road. Its not that hard to cut the rods, i spent 8 bucks on this little hand saw and walla, i was cutting rods like no one's business.
So list of features
Rail design, each side can attach together. You can be creative on how you might want to create you're rig's base and build vertically if you get some long 1/4 inch bolts or threaded rods to make a multi level rig.
With rails I tried to have snap on parts that can slide around and be locked into position with thumb screws. It works, but not as good as I hoped because tightening with the thumb screws causes the plastic to push out since there is no bottom support.
Beyond the standard two rod connectors there is single rod connectors. This allows to create snap on bits that are longer then the side rails. Allows more customization for me in the long term.
Using the single rails, i created vice walls that can be stacked one after another. There are PCB grooves cut into it so you can hold boards. There is quite a bit of space so the under leads on the board does not touch the rails. I didn't want to ruin my boards or give myself a shock.
On one magic arm I put together a pcb vice. In case I want to hold boards in some other manner then just being on the base vice. Besides, it looks pretty bad ass connected to the arm.
Snap on slider bit that you can easily screw on flexible water pipes onto. No point in 3d printing this since you can get 6 arms for $7 bucks on amazon. Using a 1 1/2 inch #8 screw, I was able to attach alligator clips onto it. Works pretty well. On top of that, you can run wire through the hose and out of the bottom of the rig if you wanted to make some arms do things beyond just holding bits.
So its a work in progress. When new needs arises I'm sure to create new bits and post them here. I really wish I can get some really long stainless steel rods in metric that I can cut to size but so far I've only been able to get up to 300mm length stuff on amazon. So when I get myself some good rods I might redo this in metric. so far only the pcb vice on the arm uses metric rods.
