Chasis

I won this on eBay earlier today, it's a carpet sweeper just like I need but I have a little concern that it IS made of wood. Should be ok, a little heavier but generally speaking I assume it is going to be somewhat easier to work with. Looking at a photo of the underside it has four wheels that are fixed in position, so I don't know how I am going to play this, I may wind up attaching new wheels to the side. I also picked up 6 infrared LEDs to project infrared in front of the thing and four IR transistors to pick up the bouncing infrared off an obstacle, at least that is the plan. This thing will arrive in a few days from Frankston, Victoria (WTF is someone in Frankston Victoria doing selling (just the head of) a carpet from the 1950s on eBay?). The PIC programmer I bought (for $17!!! w00t!![+7p/h]) will take longer because it's coming from Bulgaria. I might tool with the infrared leds tonight and see how they work, I'll rig the emitters and see if I can't make a light light-up connected to a receiver - good to test range too.
