So what's involved in making a HDMI to VGA adapter for the Raspi? Does anyone have any circuit designs to do this?
I can't see this being easy (unless there are off-the-shelf IC's to do this)
HDMI is basically high speed digital data, whereas VGA is analog RGB with some timing information.
Any DIY system would be an ASIC or Fast FPGA.
There are existing products to do the conversion for about £50/$50, its not going to be a simple cable and so any £5 cables will not work.
If you simply want to via the 'Pi on a PC screen, then the options are limited;
-VNC/Other remote network access
-HDMI to VGA module
-Purchase a more flexible PC Monitor with HDMI or DVI (this *should* work and you can get cables to change connections..)
(note: small royalty payment required for HDMI products..)
