Does anyone nknow of any code I could use to turn a digital tuner into a spectrum analyser – Ive pestered Hauppauge and a few other companies but none are willing to let controlcodes for these tuners out – For the I2C part thats well know but id love to control it by direct commands/code in Linux/windows etc to provide the capability – ie put mixer in front of vcard and sweep frequencies and monitor level out.

Craigslist is your friend.

I’ve picked up free working eletronic items (oscilloscope, etc) from there.

@Ian, thanks! I’m still waiting for mine, I’ll make sure to check it out as soon as I receive it :)

@therian True.
@Natrix You made my day

Like this project, maybe I start reverseengineer that isa 3d Card without driver cd. and I need a
logic analyzer… Thx hackaday “friends”.

@ Danial Reetz & Eric – There’s a bunch of I2C demos in the ‘parts’ category:

There should be one for an I2C EEPROM just like this one. You can also check the manual on the Google Code page.

STOP REFERRING TO WINDOWS AS “PC”
it plain stupid and annoying, and to here this on hack a day make it 10 time worse. If you want to refer to operation system call it by its name not hardware. By the way macs pars made by same manufacturer on the same factory as other Chinese junk hardware parts

So “real hacking” is anything involving reverse engineering?

I like a lot of the non-reversing stuff here. This isn’t a reversing site, and hacking isn’t exclusively reverse engineering.

This is cool and all but the ‘finally’ comments are kind of annoying. Are we going to hack banks across state lines next to appeal to this demographic? ^^

@Mike Szczys, I understand you need to use the right tool for the job. I do like the option of modifying source and fixing problems instead of waiting for the next service pack, just no desire to do it. :)

Less of an issue with Linux/Windows/Mac but more of the lack of testing or support on the periphial side.

@The Cheap Vegetable Gardener: I’m not ‘trying’ to be a jerk here, but I use a PC as well. I just choose to use a superior operating system like Ubuntu because there about are about fifty times as many things about those other operating systems that drive me crazy.

Hmm, maye this is why I use a PC, I don’t have to use a logic analyzer to get your tuner card to work :)

Awesome!

I bought a hvr-1600 recently for mythtv and have been a little put off by it’s tuning.

Thanks again Kernel labs for all you’ve contributed!

Awesome. A real hack, without using a silly Arduino! Great work!

I agree with Daniel Reetz!

As dan said, I’m pretty sure I’m smart enough to do lots of things, but since I haven’t done them yet I don’t know where to start :)

now we’re hacking! :D

@saimhe, you probably don’t use a logic analyzer much simply because you don’t have it. I used to say exactly what you are saying… until I got mayself a cheap logic analizer and a cheap scope from a garage sale… noww I use them everytime I can and they also helped me get into some new projects. go ahead and buy one from say… ebay… one of the cheap usb ones. you’ll notice how much more you can do once you have proper tools.

PS. I still love my $4 multimeter ;)
