Quickstart mounting adapters/brackets.

In the process of building out my robot I designed it with a 0.500" grid of mounting holes for locating parts, sensors and electronics. Problem is that often the spacing on electronics is usually just whatever happens to fit. In this case the Quickstart is 2.75 by 1.75 and while there is nothing wrong with that it certainly doesn't work with my adaptable grid design and the Arduino is worse. All I could do was attach a single stand-off on both boards. So I made a few adapters that I hoped would also be useful in other projects as well. They would adapt to both a 1" and 0.5" grid and have slots to allow for non-square/non precise mounting.

The holes were all tapped as 4-40 except for the ones used to hold it for machining. The slots are 0.195" and would accomodate #4 or #6 screws with washers or #8 screws as well. One set of slots would mount on 1" centers, while the other would mount on 0.500" centers. They were all powder-coated here at home.

I really like how they came out. Worked nicely for getting the boards secured to the robot in a nice solid manor and can be moved from place to place with ease. I have 2 left from the test run I made and if anyone is interested in them you can send me an email at kyle@cranehome.info if you'd like to have one. I'll give these two away for the cost of shipping. If there is any other interest in them I imagine I could make up a small run or two. Colors can be matte black, gloss yellow, or gloss red.

Also pictured is the Arduino Uno version. Both are made from 0.125" AL and weigh in at 0.5oz.

    Very nice, if I didn't have mine QS's mounted in an enclosure I would be first in line!

    Those look really nice.

    I just sent you an email.

    Thank you guys! I'm considering going to Delrin/Acetal for this but some part of me just really appreciates metal parts and powder coat comes in every color you can think of.

    Wow! Those are really nice! And the powder-coating sets them apart from run-of-the-mill brackets. How did you get the edges rounded on both sides?

    Thanks Phil! The backside was just run around with a manual deburring knife. It would be a major pain to flip them for a machined chamfer on the back and a small alignment issue would make it ugly quick. The powder coat just magnifies the small chamfer the knife gives it and tends to round it over a little bit. Nothing beats a 90* pointed end mill for looks though when the machine does the chamfer. It just looks sharp as heck
