Idea for a new thread: "What can I build with XXX transistor/IC?"

[Will.mendil]

Hi, I hope I won't be disappointing anyone who would be looking for what I am as well.

Is there a category, in this forum, that   lists all kind of transistors or ICs and what one can do with it? If not, don't you think it ought to be made.

Maybe a website already exists, in which case I hope someone can give a link.

The idea would be to have a thread for each type of transistor (i.e. 2N3906, or 2N6520 etc...) and examples of what could be built with it. The reason is that I have been harvesting semiconductors from every all kind of equipment I could get my hands on and most of them I don't know what to do with them.

I am sure I am not the only one to deal with this, but I cannot find any reference! I am not sure such a thing is on this forum.

Anyway open for discussion! I'll just list below all the components I have got so far ( not all stomp box related, some surely useless), and maybe we can start from there. If this takes up, I'll might put a blog together are at least start listing the ideas you guys have.

This is a long shot, but I am looking forwards for you insight

Cheers
( I've written everything that is stamped on the component, so I do realise that there are doubles and so on. It's just a crude list to start from)

Note: I am not looking for a list of data sheet links, nor a list of what every one here has, obviously , otherwise, this list will just end up being a list of odd numbers)

There are probably as many circuits as you have components, not to mention all the variations and mods. Plus a ton of them are replaceable with another type such as a bunch of opamps, 201/MFP102/2N5457, etc.

Maybe it would be helpful if you organized your list at all - delete duplicates and start a classification or organization system so people wouldn't have to look at a gigantic list of capital letters and numbers! Organize them so that like components are grouped - you might have to do some googling and looking at data sheets to figure that out.

[Will.mendil]

There are indeed, but maybe I was misunderstood, I do not want you guys to list I ( personally) could make with what I have, the idea would be to list different effects according to what semi conductors they use.

I guess I ll put up a blog and start listing. I'll post the link when I have a a bit of content.

It's more link a beginners guide I guess.

Not what you asked for but this may be of some help as far as transistors go (cross reference): http://www.alltransistors.com/  
Would sure love to find a site like this for op amps. Anyone?


"Is there a category, in this forum, that lists all kind of transistors or ICs and what one can do with it?"
You're mad! Mad as a hatter I tells ya! There must be thousands of transistors that can be used to build any particular transistor circuit, if one can be bothered to do a little math and adjust the biasing resistors, and so forth. Ditto for ICs (op amps anyway). (ditto? what the hell?...)

...the idea would be to list different effects according to what semi conductors they use.
Ah, perhaps it was a momentary lapse of reason.  That could work....

There's this mic preamp I built that uses an AD797 (schematic in The Audiophile's Project Sourcebook by G. Randy Slone)
I built a 1-2 watt amp using an NJM2073 (schematic in the data sheet - BTL application)

Was that helpful?

I think this is a classic case of "Google is your friend". If you've got a component number and a rough idea of what you'd like to use it for, that's your search right there:

2N3906 guitar
2N3906 synth
2N3906 robot army
etc...

[Will.mendil]

I guess MaxPower got the concept. Of course there are thousands of different type of transistors, and thousands different type of schematics/ mods. But just like site such as madebean, tagsomething or tonepedal (pod... I can't remember). I just list common transistor and link them to schematic. And add more exotic ones.

So basically, even if you have already posted it somewhere else. Just put the kind of transistor, the type of pedal, a  name and a schematic( and other layout documentation) I'll do the filtering.

[Will.mendil]

oh, but i can't really put anything from books now can I.

[duck_arse]

I rekon you might be going at it backwards. I've collected a shirtload (that's a metric measure) of circuits, and sometimes I'll think "what was that thing with the overhanging doo-lappers?". of course, I never can remember and have to search all the overhang circuits and anything that may have a doolap of any description.

and so I always end up thinking "I should go through my collection, and describe each circuit into a database af subsections, difficult parts, odd methods etc". what you might be better doing, and it would SURELY take less time, is to database all the semiconductors in the circuits you come across.

[Will.mendil]

I agree with you duck bottom, and that's what I am doing. I am putting a blog together right now, it has nothing on it yet, but I am going to try and post the schematics I can find on ( making sure I am allowed, of course) which will be a start, but since I have not a tone of experience, It is going to be slow. That's why I am  hoping to get some of you to send me some of your stuff. The message would be:

the name of your pedal
where did you get it
link to the schematic
what type it is
what transistor it uses

I am not expecting you put everything you have ever built, but maybe your last working project. I'll put the database together.

I am looking forwards to get some feedback/submission from you guys. The more people chip in, the faster it will be

[Will.mendil]

Ok, so Ii've just started, there are only 3 schematics for now, but I intend to keep adding as much stuff that I can find. Hope you find it usefull.

I woke up this morning wondering if I came off sounding like a dick in my previous post. Didn't mean to.

Axis Face (fuzz): PN2369A, BD139
Arbiter Fuzz Face: (pnp, germanium): NKT275, AC128. There are variations.

A couple of sites with the Big Muff Pi schematics/parts:

The list goes on and on. Google is your friend as anchovie posted.
EA Tremolo
The creamy dreamer or dreamy creamer, or whatever it's called, is another one that comes (ha!) to mind.

[bukas]

you need database to do that, so if you have lets say a tl072 and do a search on it, you get back results with effect names and schematics. i would add a filter like "what circuits can i build with this part as a replacement" think that could be helpful

[Will.mendil]

I am doing it on wordpress. Indeed the database would be better, but this way is easier and less trouble. I'll look for your stuff max. Thanks.

I'd rather not do the replacements since it is going I be an impossible task. Especially since I m not that an expert with transistors. I might do that much later

[Jopn]

My thought is that you'd want to start stockpiling schematics with nicely formatted BOMs.  Then you could search through the BOMs for your part in question.

I've had a similar thought in the past when I've received a care packaged from Tayda or Futurlec 45 days after placing the order, and found myself scratching my head trying to remember what on earth I was planning to build with the odd ball components in my parcel.

[Will.mendil]

Bom?

[Will.mendil]

Oohhh. Yeah. That might be easier. Did you say you started a list too? I'll do that when I am done building this new pedal i struggle doing
