Bluetic Posted November 22, 2005 Report Share Posted November 22, 2005 I am a total electronics idiod. Could somebody put this Black Ice mod into total laymans terms for me? I would like to try it but I totally dont understand the schematics in the tutorial section. You say Schotty diodes? Are there any specific values on these? Where do I solder them to? Does this replace the cap already there? I am truly sorry for being so ignorant on this subject. But would like to learn more. Thanks in advance for any help on this.

rhoads56 Posted November 22, 2005 Report Share Posted November 22, 2005 come on mate, the info REALLY is already here. Trying searching again, its all there.... and you'll learn more by searching in this case. Also search for strawberry ice. Quote Link to comment Share on other sites More sharing options...

Don't be an idiot, listen to rhodes, get off your lazy butt and do a search. That American enough for you? Quote Link to comment Share on other sites More sharing options...
Samba Pa Ti Posted November 25, 2005 Report Share Posted November 25, 2005 i was lookin at the black ice mods and decided i didnt like the idea, going to build a treble booster instead Treble booster Schematic (old but i found all the parts) Quote Link to comment Share on other sites More sharing options...

My question --is there a way to get a similar effect WITHOUT resorting to a battery driven device? Quote Link to comment Share on other sites More sharing options...
Samba Pa Ti Posted November 25, 2005 Report Share Posted November 25, 2005 i doubt it would work without a battery, im just trying to get the queen sound, although it works for other styles of music just depends on the pickups (shame i cant afford a vox Ac30 =/ ) Quote Link to comment Share on other sites More sharing options...

rhoads56 Posted November 27, 2005 Report Share Posted November 27, 2005 well now you should share that info, so the next guy doesnt have to complain when it isnt all handed to him on a silver platter. Thats what the forum is about, and what you expected... right? Quote Link to comment Share on other sites More sharing options...
BJPUC Posted November 27, 2005 Report Share Posted November 27, 2005 (edited) can someone simplify the schematic for the treble booster thingy? Its gonna be my first electronic build. Im basically clueless on what the symbols mean, i guess what im asking for is a current list of parts i need to purchase and can i get them at radio shack? and if some one is could make a simple drawing or something to that effect of the how to assemble that would be great. I have looked at the schematic over and over and just can't get going. any help???? Edited November 27, 2005 by BJPUC Quote Link to comment Share on other sites More sharing options...
Daniel Sorbera Posted November 27, 2005 Report Share Posted November 27, 2005 (edited) Umm... It says exatly what parts you need in the box that says "components". Just print out that page and bring it radio shack and they'll know what parts to give you. and the picture under the schematic even tells you where to layout the components and how to wire it up. You can't get more simplified than that. With that layout and the schematic if you still don't know whats going on I sugest you check out the info found in this pinned thread...

Samba Pa Ti Posted November 27, 2005 Report Share Posted November 27, 2005 ahh i might post a schematic when i finished it the transistor was hard to find but not impossible not sure if radioshack will have it Quote Link to comment Share on other sites More sharing options...

Samba Pa Ti Posted November 28, 2005 Report Share Posted November 28, 2005 Original my version sorry for the rushed ms-painty-ness and if there is any visable mistakes point them out since i havent made this yet. this is my interpretation of it anyway.

rokeros Posted November 28, 2005 Report Share Posted November 28, 2005 This i probrably not linked to what all you guys are saying, but it is still conserning the black ice. As you know, there is a tutorial of the black ice on pg.com that is ez as pie. 2 diodes neg-pos, pos-neg grounded, you know which one. Not bothered with the link, but anyways I was wondering if it is possible to use 1N4148 instead of the recommeneded ones they suggested. Its becos I want to try it out quite and those are the only ones I have spare left over from my TS-808 project. Are there any retrictions, or should I give it a try?

Samba Pa Ti Posted November 28, 2005 Report Share Posted November 28, 2005 id look up the specs of each diode and the suggested ones... i was thinking of substituting some transistors but when i looked at the spec sheet they were 100's out.

lovekraft Posted November 28, 2005 Report Share Posted November 28, 2005 ...I was wondering if it is possible to use 1N4148 instead of the recommeneded ones...It's extremely unlikely that you'l get any results at all with 1N4148s ( or any standard silicon diodes) unless your pickups are invredibly high output. The reason for using schottky diodes is their low forward voltage, which allows them to clip at much lower levels. Quote Link to comment Share on other sites More sharing options...
JohnH Posted November 29, 2005 Report Share Posted November 29, 2005 The reason for using schottky diodes is their low forward voltage, which allows them to clip at much lower levels. ← All true. Theres another effect as well. I made a rig to measure current and voltage across a Schotky at very small signals. Knowing those, you can work out an effective resistance for the diode ()R = voltage/current), which changes with voltage. It turns out that as the voltage reduces to zero and becomes negative, the Schotkys resistance is continuosly changing. From +20mV to -20mV, resistance changes from about 70k to 40k, and continues to change with larger signals. Those resistances are right in the money zone for changing the tone of the pickup. Hence the schotky is changing the sound in a non-linear way all the way down through the decay phase, and way below their forward voltage. By contrast, as silicon diodes approach zero voltage, their reistance is several mega Ohms, which has no effect on the signal, and they only clip as their forward voltage is approached.

Anti-Idiot Posted November 29, 2005 Report Share Posted November 29, 2005 i used a Ge diodes (1n34 or replacement) and i worked pretty good. i have generic chinese humbos, sound horrible, but w/this diode, the sound got more crunchy, overdriven. I used 1 for asymmetrical clipping. Quote Link to comment Share on other sites More sharing options...
lovekraft Posted November 29, 2005 Report Share Posted November 29, 2005 It turns out that as the voltage reduces to zero and becomes negative, the Schotkys resistance is continuosly changing. That's pretty much true of any diode, since the forward voltage varies with current and the relation is nonlinear. http://www.ortodoxism.ro/datasheets/SGSTho...ics/mXyyrst.pdf Take a look a figs 6-1 and 7-1 for an idea of the I vs V properties of a 1N5817 - they're not a lot different from the curves for a 1N914, but at a much lower voltage.
