Stingray Grommet Tip
Hey Stingray folks,
I found a grommet that fits the large hole on the Stingray Chassis plate. It is available at O'Riely Auto parts stores. It is a Dorman Help! #42317 PCV Valve Gommet for GM Vehicles - See http://www.eautopartstore.com/auto-part/795856-help-42317-pcv-valve-grommet·and attached picture.
For the small holes in the·sensor·mount plates, Radio·Shack's Vinyl Grommets (assortment) work great. It is part number 64-3025. See·http://www.radioshack.com/product/index.jsp?productId=2103392 and attached picture.
Let me know what you think.

Are they all charged up and ready to go at all times? Run them all simultaneously and video THAT!
PS: I've used the Shack's grommet collection to hold my Heathkit Hero robot panels as well.

My wife would say too many!
Actually, it is not that many. Beside toys and some·little starter kits·- I have the Solarbotics' Herbie, the ChiBot Alpha that you sold me, a Boe-Bot, a Prop Proto Board Bot on a Boe Chasis,·two good Scribblers (and one damaged Scribbler) and the new Stingray. I keep them (battery-less) till I play with them, so they are up at all times.
I kinda play with them one a time and just go back and forth learning different things. I just really enjoy playing with them all. I get excited about something new on one and work on that and then work on something else a while - it is not very efficient, but fits my schedule.
@Chris
Can't wait...

Great video!
I was not leaving out the 12 Volt Motor and Wheel combo, but they are not a part of a complete robot yet. I also have a Homework Board, a couple of Propeller Proto Boards and the Propeller Professional Development Board.
My earliest robot and robot-like things were BEAM bot made from kits or old electronics junk. My misguided-ness, electronically speaking - began as an adult.

Have any of you had experience with using VeX robotics parts with it? I'm hoping to be able to build on to this thing using some of the metal hardware (might have to drill or cut?) and maybe even the VeX servos and sensors.

Thanks
I use 7.2 V NIMH batteries in mine. These batteries are available at any RC hobby shop for a reasonable price (mine were ~$35 for 3000 mAh). It comes with a Tamiya connector however. To make it work I created a male tamiya to male barrel jack adapter, and plugged directly into the barrel jack input. For my charger I bought a cheap Turingy charger online that can charge multiple chemistries of battery. So in short, rechargeable batteries can be had either locally or online.

Looks really nice, and came with a bunch of extra electronics bits I wasn't expecting (like leds and ir and such, similar to the boe bot). I guess I should have looked more closely at the pictures.
Anyway, I'm sure I'll be back with questions later.

Thanks for providing your solution.· I would be interested in hearing what Roy does for power on his new Stingray kit.· I am also curious how long the (or your) batteries last.

Initially, I plan to attach it to the Stingray using a hold-down strap thing I got for use with the VeX, and I'm going to put it on top along side the board (where one of the handles currently is).
Here is a link where you can see the stuff I am using: http://vex.innovationfirst.com/vex-power-products.shtml, they also sell the Battery straps alone for $5. The connectors are fairly standard R/C car/toy stuff, so you can also buy batteries and I am sure straps and clips at any hobby store or electronics store that sells R/C stuff. Here's a link to a Radio Shack part that is what you'll need to make the adapter: http://www.radioshack.com/product/index.jsp?productId=2062132·They also sell 7.2v batteries and chargers for a cheap price of ~$20. (here's a link to a online seller that is much cheaper for the connector: http://www.allelectronics.com/make-a-store/item/CON-210P/2-CONDUCTOR-RC-BATTERY-PLUG/-/1.html).

I wouldn't buy the battery holders from Vex unless you have to. I am using some very nice one piece velcro straps that I bought from home depot (or lowe's, don't remember) for about the same price but for a roll of 10 or so. And not to be too negative here, but unless you are in Vex (and the rules require it) I would transition away from NiCad batteries. The memory effect is generally considered to be a pain.
I will comment though that I like what Vex is doing in the world of introducing younger students to robotics.

I have some MiMH 7.2v batteries I got from other places, because they are better than the NiCads. I'm all too familiar with the memory effect issues (going back to my R/C 10 race car from many years ago).
I've got my Stingray assembled along with the 3 PING kit installed and tonight I'll be hopefully writing some code to make it run around and avoid bumping into things.

I haven't been out to purchase the proper connectors for making a "good" adapter, so the stuff in the pictures is just a temp hack wiring so I can test things.
In that last pic I show where I used some of my VeX hardware (the standoffs) to mount the servo for my 4th PING (for reverse)·that is using the bracket/servo kit Parallax sells.
The two sensors in the breadboard are the two-axis accelerometer module and a compass module.
