yea i thought id seen that symbol before for a specific type of clipping, like bilateral r whatever.
huh. well itd be a LOT easier to understand if hed just said 4148 or whichever one he used. obviously the diodes he used didnt say "Si" on them.
He also left out the Vcc +&- for the tl0621 etc
well, Thank you-I appreciate it. I coudlnt find it by searching, just came up with "Si Units" which are, apparently, some unit of measurement also used in schematics.
Just FYI, I left the diodes completely out of the circuit and it worked fine..so just fyi if anyone builds it. |

It is not uncommon to label non-critical diodes or transistors with just Si.
In elektor schematics you'll also find DUS, TUP, TUN - where D = Diode, S = Silicon, T = Transistor, U = Universal, N = NPN, P = PNP.
BTW, not all diodes are labeled, so when you pick one from the heap it is not always clear what exactly it is - when a quick check with a meter reads 0.6V - 0.7V it must be silicon. _________________ Jan
also .. could someone please turn down the thermostat a bit.

ah now I get it :
Silicon is a nonmetallic element (number 14 on the periodic table) found
in the earth’s crust. The element is a major component in semiconductors,
and its high conductivity makes it useful in solar power cells.
Silicone is a class of silicon-based chemical compounds used in paints,
adhesives, lubricants, and breast implants, among other applications. _________________ "My perf, it's full of holes!"

Yup, and silicium is Latin
It is funny tho, in English a lot of Latin words are used where we use Dutch words, and the other way around .. or something _________________ Jan

Having a chemistry background, I can usually work out what is meant, even if names are misused (e.g. silicone instead of silicon). I do draw the line at spelling sulphur with an f (now the official spelling):

SI units cover the whole of science and technology - not just electronics

Don't know if this helps anyone - I just felt like saying it...

Just now seeing this, Si si hombre, it should just work
The idea is that it distorts a bit softer on overload with the diodes in, but you may actually like more clippy clippings.
Otoh if you'd want even softer clippings at a lower level you could put in Ge diodes. _________________ Jan

thanx guys, def. the more info im armed with-the more dangerous i am.
fr whatever its worth, the gargletron isnt really all that impressive, i normally throw in lm324-based lopass filters in stuff all the time-its an easy circuit that runs on 9v and is really effective..so, fr whatever its worth-i dont think this particular project is worth the relative time/effort involved for the outcome.
some one else might disagree but i tend to want MORE effective filters, not less, but then im hardly ever using for, say, vocal, or non-distrted guitars. |
