[Wizard] Heat and Power
Fri Sep 5 16:17:32 2003
I recently had my Wizard sitting on for about a day or two (just idling, early on I was dumping mp3s onto it), when I opened it... the heat was a bit more than I expected. Has anyone else noted the significant heat build up? (not to dangerous levels, but still painful to touch - it was just idling).
I've done some bending of the cables to completely uncover the heatsink/spreader, I'll see how that goes. (unfortunatly, no proper temp. measuring devices are on hand)
For those of you with Compaq iPAQs or similar with an car power adapter, these little cigerette lighter adapters are a 10V-30V 1.5A DC to 5V 2A DC. Slightly wrong plug size, but that is fixable.
The 8250s are rated at 8 watts (8w/5v=1.6A), the HDD at 0.5A. That gives you a total of 2.1A at peak... it MIGHT be a viable solution to those of you looking for a handy (!=cheap) car adapter.
I'm not entirely sure what Nokia phone's take in, I -think- it's 5V DC, but the amperage on their PSUs/car adapters are way too low for our purposes. (~500mA)
I am currently looking at some biscuit PC suppliers, I'll make some calls on Monday. [I have seen a PC104 car power transformer/regulator in the PC104 form factor, designed to plug into the PC104 bus - it would sit below/ontop(?) of the 8250. Not sure of cost.]
