power resistor

i made this little guy up today, though my psu worked without the load on the 5v rail, when i put this buy on i got just a hair more voltage out, enough to notice it any how. but i just did some digging today and found that heatsink.

 so i drilled it out and bolted it on, and now it feels allot cooler, it was borderline hot without it. now it is just shy of 40c after 5 min, so i am doing allot better with that.

on a little side not, i got this keypad LCD shield today and i got it working with a one wire temp sensor, though my programming kinda sucks, i want to try to get it to save a hourly average throughout the day so i can then transfer them onto my computer and chart them out. there is allot more i would like to do with this project but every time i try to do more than the most simple things my brain just goes blank, its not very helpful for making progress on things.
