Re: Bobcat " Skid-Steer" Loader.
Thats great! Perhaps a tele-handler would fill out a pwd car wheelbase better? Good work!

Re: Finishing weight gain?
I set up pre-paint weight to 4.9oz. Only 2-3 coats of color and an electrical tape racing stripe put both cars this year right at 5.0oz.

Re: RaceMaster 4 DIY from Bosworth??? Anyone have success bu
Things got hectic as usual, but I was able to complete this project. Only lost 1 nights sleep and a smal bit of my sanity. Total time invested was well over 30 hours between the breadboard build and final build. Using this and a computer with an MS-Excel tracking matrix made our event run like a cha...

Read up a bit. There are low cost DIY options and plenty of help on this board. Ask around the parents in your pack if anyone is good with electronics.
Passing the hat never hurts either.

best end of block to use as front?
I've been reading quite a bit and still confused over which end of the block to make the front. After looking at plenty of designs, it seems that most "speed" designs use the longer end forward (standard wheelbase). As long as the COG is in the ~3/4" forward of the rear axle, does the...

Testing completed. Wish I would have laid out the LED drivers a little better... would have made for less wires. Otherwise it works like a charm.

Re: RaceMaster 4 DIY from Bosworth??? Anyone have success bu
I have also modified the plans to run off standard 110AC power rather than a battery pack. I assume that you mean an AC to DC power supply. I certainly hope you aren't supplying 110V to that circuit. :eek: haha.... yep. 110VAC to 5VDC power supply. Don't have to worry about batteries dying and a po...

Re: RaceMaster 4 DIY from Bosworth??? Anyone have success bu
I don't want to throw water on anyone's creativity or desire to reduce expenses, but I think the MicroWizard kit timers, which tell you order of finish without a computer, are pretty affordable in the ~ $50 - $60 territory (have to check current pricing). How much time/money is the Bosworth option ...

Re: RaceMaster 4 DIY from Bosworth??? Anyone have success bu
The fact that it is not reliant on use of a computer is what I liked about that setup. Our derby will only have about 40 entries... so we don't need anything too sophisticated. We have always used paper to track results, but this year we are going to try using a spreadsheet to track, and with the he...

I found the following drawings for a Lane Judge titled "RaceMaster IV"... http://home.simplyweb.net/bosworth/timers&.htm" target="_blank It seemed pretty straight forward until I started putting it together. I started with the 555 timing circuit to dial in the frequency... th...
