Re: 1.1 Pump (am-3227) Really an improvement?
There's actually pictures of it here on CD I think if you browse the photos section a while. We did something similar to this on our 2011 bot, but we just mounted one of the 120mm fans next to the...

Re: 1.1 Pump (am-3227) Really an improvement?
I'm partial to the 100% duty cycle compressors myself, those light-duty compressors heat up way too much.
BTW, this is a good place to compare and find different compressor options (as well as other...

Re: Where to purchase wire?
When we first went to zipcord style wiring, we were able to get some (limited selection) locally from RadioShack (back when it was a thing), since they sold it as "speaker wire". More recently we...

Re: FRC Team 1296 New Car Raffle (2017 Mustang)

Even at 1 in 2500 those odds aren't bad for a prize like this, and it looks like you can still make a pretty good return even if you have to...

Re: Cooler Master Keyboard Giveaway
What's the latest date (approximately) that anyone could expect to receive a "surprise keyboard"? It would be nice to at least know if we're not getting one.

Re: Robostangs 548 2016 Offseason Rocker- Z6
Sometimes flexible is good though. Aluminum will deform when it takes an impact which can be difficult to fix without replacing the part, whereas polycarbonate will just flex and return to its...

Re: Graphics Cards for CAD?
To be honest it doesn't take much to run CAD/CAM comfortably. I personally am using an nVidia GTX 970 on my desktop at home to run Inventor, but I have also run it on a GTX 760 and 480 in the past...

Re: Robostangs 548 2016 Offseason Rocker- Z6
Don't get me wrong, I don't have a problem with using polycarbonate (we've used it extensively throughout our chassis for years) but it looks like you're using maybe 1/8" at the most?
On our drive...

Re: Robostangs 548 2016 Offseason Rocker- Z6
Interesting Chassis! I am a bit curious as to what its intended purpose is though.
The only reason I could think of to use what appears to be thin polycarbonate on the side plates (and nowhere else)...

Re: 3D Printed Parts on an FRC Robot?
I can't speak for everyone else, but I do know that Autodesk Inventor has a tool that allows you to generate standard sprockets/gears/pulleys of various sizes and tooth counts.

Re: 775pro .5" Hex Output Shaft
Why not just use a 1/2" Hex versa-planetary (http://www.vexrobotics.com/versaplanetary.html) with no reduction? The tolerances will be much better and you'll have the added bonus of standard mounting...
