Tivo Tivo Tivo!

TurboNet card arrived yesterday. It’s an amazing feat of engineering – a tiny little custom-made ethernet card that fits into Tivo’s ISA slot and is powered by the motherboard. Install took 3 minutes (good hearted Tivo engineers included drivers for it with the latest version of software) + 5 minutes to staple cat5 to the wall. Well, and half an hour contemplating Tivo’s insides.

What am I gaining from having an ethernet card in Tivo?

Well, for one, it will not be phoning home every day. 30 calls per month at 5 cents each is not a huge saving, but I will not have to unplug the phone cord during thunderstorms.

I already had a burned out modem once. The nasty thing about it breaking was that it kept phone line “of the hook” so that nobody could call me. I had to send my Tivo to a Texan who goes by the handle Electriclegs. He figured out how to fix Tivo modems by replacing a few parts and even made a repair kit available, but I was not brave enough to solder surface mount components myself. The repair cost me $50 + shipping, but the worst thing was being without Tivo for a couple of weeks. Brrrr.

Things left to do:
1) Install bigger hard drive (not simple because I have a double drive model)
2) Mount the ethernet jack flush in Tivo’s case (cold not do it this time because my nibbling tool broke during cutting a hole for exhaust fan on my computer)
3) Install TivoWeb, other neato hacks
4) Learn to solder surface mount components, install memory kit from Electriclegs
