 Teams must bring their own water. Water must consist of a low viscosity and at it's maximum width must not be larger than 12 in. - Bkeeneykid [more] |

Re: IR board improvement
Mike.
I agree that a diode across the regulator with the cathode at V in is appropriate with a larger output capacitor. Not sure if that needs to be the case here. However, I would recommend a 10 mfd near the chip just to protect against transients when the LEDs turn on. I like the use of the RC 5 volt rail but the you should then keep the big cap in place to filter the power. One team at Boilermaker had a short on the board pull down the RC 5 volts. Perhaps a small fuse is in order as well. |
