on the epilepsy hack... i read more about it here: http://www.news.com.au/technology/story/0,25642,23460969-5014239,00.html
seems wired covered this and more people have looked into it since. there seems to be a lot of blaming being tossed around on who did it so at this point it's impossible to tell. it's aggrivating that everyone has been blaming anonymous since the fox news garbage, and i wouldn't put it past scientology to be the actual culprits of the attack.

this is the same idea used in the Blue Ball mic (fixing impedence issues with an integrated amplifier through phantom power)

I have a copy of his FET buffer amplifier in my stereo homemade Touch Guitar.

Even the 9-Volt version works well.

Oh man. I'm one of the CoS protesters, and I really don't understand how people could be blaming us for this thing. Anyone can be Anonymous, you need to take a look at the *chans these griefers operate on. Like Jack says, the whole CoS raid is actually looked down on by lot of the *chans. Scientology looks down on its members taking medication to stop them from getting seizures, for example, Tory "Magoo" Christman - http://www.entheta.net/archive/personal_story/tory/affidavit.html

Jocelyn Dorfmann died from an epileptic seizure in Scientology care in France - http://www.whyaretheydead.net/others/Jocelyne_Dorfmann_34.html

Heribert Pfaff died from an epileptic seizure in a Scientology hotel in Clearwater - http://www.whyaretheydead.net/room758.html

James Stewart committed suicide after CoS put in him in a Condition of Doubt for having epileptic seizures in public - http://www.holysmoke.org/cos/kult-epelep.htm

Is there a reason that the guitar hack comments section has turned into an epilepsy victims support section?

Granted, it was not a really nice thing to do.. But honestly, my
question is, what kinda retard would sit there and watch the
"flashing images" long enough to cause any type of reaction knowing
that they had this disorder.. Unless of course they had some kind of
java scrip that not only caused flashing images, but also a total
paralysis of viewer preventing them from manually moving their mouse
to click the X in the upper right corner.. Then.. yes.. By all mean..
DAMN THEN TO HELL!

Anonymous really did it you guys, I think you are giving them a bit too much credit for not being douches. This is not the first time they have pulled stuff like this either, harassment is what they do. The whole CoS raid is actually looked down on by a lot of the *chans because it is destroying the name of Anonymous. They don’t call themselves “Internet Terrorists” for nothing.

IIRC the epilepsy forum either allowed raw HTML or javascript. Saw the damage from a thread on 7chan myself.

"hacker" is hardly an adequate description for those that participated, not that I support their actions.

about the epilepsy thing connected to Anonymous –

it turned out that it was people from the church of scientology framing the *chans. admins from a few of the boards talked about it.

Sweet hack, even though I don’t play the guitar.

Personally, I think the assholes who attacked the epilepsy forum weren’t actual Anonymous at all. I’m sure we all know about how Anon is attacking the Church of Scientology, and a number probably know about CoS’s “Fair Game” policy (if you don’t, Wiki it, it’s scary shit), and I’m pretty certain that everyone that reads this site can put two and two together… After all, who could possibly be easier to impersonate than Anonymous?

@vivi

It’s called ‘phantom power’. It’s 48v sent down the signal line to power things like condenser mics and active direct boxes.

Wouldn't leeching power from the audio line distort the signal ?

As for this epilepsy thing, hurting people for fun seems to be a growing and worrying trend in our society. I really hope the culprits get caught.

Nice hack,will try it soon ^^

Chris –
The point is to lower the impedance as close to the pickups as possible so that the cable doesn’t have a chance to load down the pickups (which cause reduced treble and bass). This is especially important for piezo pickups (which need a MUCH higher input impedance).

I’ve built one of these, but I never thought of submitting it to hackaday.

the griefers at that forum are douches.

As for sticking the preamp into the cable, phantom power is on any mixer that costs more than a few hundred dollars.

It'd be nice to not have to carry around a separate preamp box. I'd imagine that personally I'd use this cable for bass more than guitar, I probably wouldn't be DI'ing my guitar unless I was playing clean exclusively.
