RS Components. Bloody great service and professional as fuck, and although they cater mainly to industrialists, they're always happy to deliver stuff to small buyers.

Oh yeah, there's also some russian guy who does all of this with a piezo element under the neck pickup and a 386 driver,

Fernandes and Sustainiac are a ripoff, and a compressor or a fuzz pedal will only give you limited sustain. Basically what you have to do is a small speaker to drive the strings infinitely, cased into a really slim pickup. Oh yes, you'd have to be willing to gut some pickups, these will only work as the "feedback" pickup after modding it.

This guy has made perhaps the most comprehensive tutorial on the net on sustaining pickup configurations:
http://projectguitar.ibforums.com/index.php?showtopic=24211
Single coils are recommended here (which is what I also made for a friend), but I guess a humbucking one is also ok, given you do it conciously enough.

At some point you'd have to make some calculations for the pickup itself, here's a great calculator. It's already configured for a sustainer:

p;ends=round&wd=0.2&id=0.22&show=on&avt=100&adj=ohms&avo=8

The driver amp can be way simpler than the ones offered by kit sellers. I tried several circuits and the Fetzer Valve worked best for me, your mileage may vary:

Other drivers that report success around the net are the Ruby (also at runoffgroove), or some kind of pulse width modulating 386 based amp.

Some older tubes had cesium or radon, which are gamma emmiters and that might or might not seriously fuck you up. But such tubes are rare. Most tubes which have radioactive elements (which are the least) contain low beta emmiters, which shouldn't be much of a problem if kept inside the glass. I think microwave oven tubes used thoriated filaments, but that's negligible, too.

Then again, pretty much everything produces ionizing radiation, so you'll die of cancer anyway.

Tomato, tomato. It pinches stuff, resembles a member of the Eusuchia clade and has prevented electricians to waste their roaches since the beginning of time. For what it's worth, they could even be named Gharial clips.

This. Do not trust your life to a $0.10 component. Always check the filter caps have bled througly, and build a bleeding tool as well, which is basically a couple of crocodile clips and a huge ass resistor.

Shit, is that for transmitter amplifiers? How many amperes to drive one of those tubes?
I am left only to guess how deadly the filtering stage for those tubes might be...

>> No.13275 [View]

>>13179
I'd be more worried of the radioactive elements in some of them, and that's already saying a lot.

And voltages, of course. Crazy high, ungrounded voltages. You don't get a respect for tubes until you have at least seen the sparks 350VDC produce. Beware of big electrolytic caps when putting your fingers into the chassis and you should be fine, and consider adding safety features to the circuit (removing the "death cap", mains ground connections., etc).

How about gutting a moderate quality meter and replacing the display circuitry with that of the nixie? Sure, recallibration would be as painful as bulkyness, but that thang would look dandy next to an oscilloscope. Large numerals are a big plus, too!.

Wow, are those fully discrete kits, or are they PIC based? Anyhow, it amazes me some for-profit kit vendors just throw away pcb patterns. Schematics are okay though... infosocialism and shit.

I guess the greater appeal is to design everything by myself, therefore I'm leaving it on hold. Tube related stuff is too expensive/precious to just randomly experiment with it.

>>12958
Well, yes, I thought of expressing +/-dB values in numerical form through the nixies. I wouldn't be aiming for much resolution (no decimals), but the expense of the whole deal makes me think i should better just stick to magic eye tubes and buy an oscilloscope with the rest (let alone finish the mod synth...)

Do you mean variable capacitors in trimmer format? Those are fairly common, although the ranges they cover are not too great and usually measureable in pF-nF, from what i've found. Now, air variable capacitors, like the ones used in regen radios... those are fairly uncommon, though with a fair ammount of patience, knowlege, and googling skills they could be homebrew.

A similar effect could be achieved by using a potentiometer, some resistances and capacitors, although I have no schematics at hand right now. Nevertheless, shouldn't be too hard to design.

>> No.12895 [View]

I was looking forward to design a fully analog/discrete/tube based nixie VU meter, but I'm guessing all that work would be too much of a hassle.

Might take upon that project again sometime, perhaps after completing a fair ammount of stages of the modular (i've been planning to make a tube based filter array for that, too, because tube VCOs sound just too squeaky for my taste)

Obligatory Cake Beaton.

Although that idea might not be so far fetched... it's sort of silly. It would be great to see actual steam powered diy nonsense in this board, like coal operated steam motorbikes, or steam boolean logic circuitry. Just a thought.

The P1 is a great starter project for tubes, and delivers amazing tone at a moderate price. Do not look down upon its 5 watts, it's more than enough to rock anyone's cock.

Other relatively cheap, simple builds (ie: good enough for people who barely know how to solder and have basic troubleshooting skills), as well as being well documented, would be Fender's 5F1 and Marshall's 18watt and Plexi. These have been particularly visited.

With all due respect, there's an unavoidable halo of faggotry around both laptop music and circuit bending. Perhaps because of their inherent replicability and lack of originality and blind faith upon randomness. But discussing such statements would fall within the purview of your conundrums of phillosophy.

Nope, let's get practical. I'm all for analog synths. From 303 clones to those humongous walls of modules. In fact I guess I'd like to get 303-ish sounds with modulars, my main problem is sequencing. I am building a couple of square/saw wave oscillators as designed by Rene Schmitz, Three Phase LFO, some vca's, korg MS20's and moog ladder filters, some 555 ADSR, resonators, and a dualb Baby 10 sequencer as made by Fonik. All in all, a moderately ambitious project.

Would it be possible to get nasty sequences using boolean logic and sequencer routers (eg., Yusynth's), or is midi control really necessary? Maybe more sequencers will be needed?

LEGOROBOT?

Anyway, why not start with something smaller in scale, like a simple dome filled with air sustained to the bottom of a sand bank with weights. You could reach it through swimming or diving, and if it's not terribly deep, you could put some plants in there in order to recycle air. That way you wouldn't have to bother with air pumping or solid constructions, or it could be a sort of first base for any other operations.

Anyway I'm kinda drunk right now so I might be babbling a lot of incongruencies.

Minecraft is for fags. And it ain't circuits, it's just boolean logic. If you want to play with boolean logic like a real man, play Dwarf Fortress.

If you want learn about circuitry, noodle around in pspice, or any other circuit sim. Hell, even better, get youself a breadboard and some components. No soldering, no harm done!

>> No.5318 [View]

oh, yeah, and I've been awarded lots of cannabis and sex for menial tasks like soldering cables. Is that profit as well?
