Re: VGA

<r>None now or not, I'm still working on a way to convert HDMI to VGA for use with this and other projects <E>:)</E>. Currently I'm busy chasing HDMI decoder chips like the tfp401a from TI and then using a small micro in front to convert the 24 bit color info into the 3 analog RGB, V-Sync, and H-Syn...

Re: VGA

<r>This isn't ideal, but here is NTSC to VGA via an Atmel ATMega16 <URL url="http://tinyvga.com/avr-vga">http://tinyvga.com/avr-vga</URL><br/> <br/> Won't give the same quality as the DVI-D to VGA option, but will give a picture on our VGA monitors!<br/> <br/> Mega16's are CHEAP, and the new version...

Re: VGA

<r>Yeah, the BeagleBoard's use a separate DVI encoder chip so you can grab the bit bang lines and basically abstract them through resistor ladders to get a VGA(ish) signal. Really what one would have to do is look at the DVI-D (I keep trying to type DVD <E>:(</E>, so sorry if one gets through) comm ...

Re: VGA

<t>I'm another one of those automation freaks named Jeremy (not the same Jeremy that started all of this) with lots of 15 and 17" flat screens lying around who would love to hook them up to Pi's. I'm wondering if something along the lines of using a minimalist (read sub $5) ARM, FPGA, or ASIC for co...

Re: Power over Ethernet (Difficulty: Moderate)

<r>My suggestion would be a standard POE interface and then feed the output into a MIC2941AWU low-dropout voltage regulator. With a bit of cheap trickery (read two standard 2n2222's) you could easily add battery backup functionality off a standard 9v batter. Kinda like your alarm clock <E>:)</E><br/...
