Re: Reliable SD cards?

From what I understand about Kingston, anything in a retail package is fine but anything in bulk or non-packaged is suuuuuuuper suspect. Those ones aren't necessarily shipped to kingston and thus are never checked. They've been trying to reel this in but it's a problem of their manufacturing partner...

Re: I return from a robotics competition!

Ha! I wish I saw any of it! :P It all goes back into paying for the club to do bigger and better things next year. We got some nice new cameras and we're currently trying to build the housings for them, but passing firewire through wet-mate bulkhead connectors is no fun at all! Matched impedance sig...

I return from a robotics competition!

Hey everybody, Jut thought I'd tell you guys that I'm not dead yet and now have some time to work on Scuzzbox in earnest, but the reason why I was so busy, I thought I should share: One of the things I do is that I'm on a robotics team at the University of Maryland and we just took third in the 13th...

Re: Arduino-like Uzebox

I would think that if you were trying to cut down on pins used (which I don't actually know if that's significant or necessary) you can just tie the not-CS pin low. Since there aren't any other devices on the SPI chain you don't ever have to worry about deactivating the SPI peripheral. The only thin...

Re: Arduino-like Uzebox

I'm pretty sure you only need to use the clock pin, the MOSI, and the MISO and you would use SPI which would be more stable than the UART. The address and data pins are only needed if you're interfacing to the module using an external memory interface (like pretending that the chip is RAM to a chip ...

Re: Arduino-like Uzebox

Ack! Don't aim for that one! It uses rs-232 voltage levels! That means that the signal wires are, at best +5V to -5V (if it's EIA-232) or as bad as +12V to -12V! This can't be connected directly to your Uzebox without doing some pretty serious damage to the internal circuitry. Unless you feel like d...

Re: Multiple 12v ~2.5A output power supply

If it were me, I'd probably rally up some ATX power supplies (pretty easy to do cheap, especially considering how many people are throwing away old machines), and then grab something like this and (if I hadn't found any being thrown away) a supply like this . You'll have to do some legwork to do thi...

Re: Arduino-like Uzebox

Well, I assume that you're going for having serial output from the Uzebox to an ftdi ft232rl, but from what I understand the uzebox itself has issues with the stability of the serial port due to the overclocking, which may be a problem. That issue aside I think that adding the second chip to do in-c...

Re: Rbox 32

This is really cool! The only big downside as far as I can see is that the programs have to be very small or very memory saavy because in order to get the execution time up to snuff he had to load everything into RAM instead of flash, and he only has ~2k-8k of RAM. But neat! And :shock: CHEAP! I hop...

Re: Scuzzbox arrives!

Thanks for the encouragement everyone :D It's always funny to see how electrically inclined people get how big a milestone this is, but of course it's entirely uninteresting to everyone else :P Anyway, I have a question about something rather fundamental to the console: what kind of standard library...
