Re: Sumo Bots B/C [Trial]

Congratulations. There's a new 4 channel radio system from GWS compatible with the rules. It's 2.4GHz (meaning you don't need crystals) and is only $42 for the transmitter/receiver. Supposedly binds quickly, but I don't have specs on interference resilience. http://www.robotmarketplace.com/products/...

Re: Sumo Bots B/C [Trial]

Each channel of control is encoded into one signal and sent over the radio link to the receiver, where it's decoded and broken up into separate PWM signal channels which can run servos, motor controllers, etc. The "channel" of the radio link is another term entirely. The radio spectrum is broken up ...

Re: Sumo Bots B/C [Trial]

Well, you're also pointing out the cost of the event while commenting on the discontinuation of a Vex product. There's more than one axis of ironic beauty to that statement.

No, that's just asking for abuse. Think about it.

Besides, the posts that use such a box might as well not be sarcastic in the first place if it needs to be made so obvious. Sarsly, it's sarcasm. Learn to do it.

Re: Computer Science Event

Perhaps the best thing would be events where you are required/encouraged to program. I believe Electric Vehicle was like this. The intent of EV was to provide a problem with a wide range of solutions. Microprocessors were intended to be one option while an electromechanical solution would also be v...

Re: Post disappears?

Ah, we were running a script on the forum to look at the best way to archive abandoned threads and to see about next year. Might have touched a few buttons that nuked a few recent threads because the script's user had incorrect timezone settings.

Thanks for the PM!

Re: Computer Science Event

Maybe something with Arduino? Arduino (== hippie hacker culture physical computing BS, btw). The Arduino project exists for all the right reasons. Yet in almost every amazing project in which it is used, the Arduino itself is a hobbling set of crutches that the project designer clings to like a hip...
