There is an old Ic which I think is still around, which can be used as a V to F or an F to V - now to remember it's part number, I think it was an LM something - used to be used a lot for rev counter projects.
Found it! http://www.jaycar.com.au/images_uploaded/LM2907.PDF

Re: Trying to debug a timeout error
Should the 169.254.0.0 entry be there? Seeing as how that is an MS provided fall back when it can't resolve to a DHCP or manual IP address.
That looks to be the routers gateway address, which doesn't look right to me - but I'm not an authority on this.

FS: FPGA Course Module from Elektor
Never used! The only assembly required are the edge connectors for the FPGA module and LCD to fit onto the baseboard. It consists of two parts - the main peripheral module board - TV, Audio, PS/2, Keyboard, USB, Ethernet, connections, and the FPGA board which is an Altera Cyclone 12,060 elements, 4M...

Not sure how relevant this is to the US hobby market but if you intend to use lead free solder, make sure you get an iron that has enough heat capacity and comes with so called lead free bits. Sadly, bits do not last very long in the pb free environment, If you can afford it, then I quite like the M...
