My project is not something tangible, but pure knowledge spewed about into paragraphs of information.
Link2

So, any errors, mistakes, or things I should probably add to this before I publish it I'd LIKE to win a 3-D printer, to make cheap encasements and parts for electronics, and hope that this guide does a decent enough job of doing so....

Thanks for the criticism!

Is this a contest or something?
Get a REP RAP device or a vertical NC mill.

Ahh a mistake!

Your diagram of the 'totem pole' has a mistake, the pnp's emitter is in the wrong place!

Tis a contest for a 3-D printer my friend.

A few things I noticed while skimming through:

wrote ...
Schottky Diodes are a very special type of diode, formed not by doped silicon, but by contacts created by two metals.
It is contact between a metal and semiconductor, not just two metals.

wrote ...
Galena
It's worth pointing out that this is a semiconductor.

wrote ...
These diodes due to their construction also have no recovery limit, meaning they can rectify just about any signal, hence the ability to rectify 100 + megahertz radio waves.
No reverse recovery time, and schottky's are used up to 100's of GHz, not just MHz :)

wrote ...
TRAN-SEEST-URR
Everyone I know pronounces it TRAN-SIS-TERR, i.e. the "i" is pronounced as it is in "is".

wrote ...
There are also two types of transistors; PNP and NPN transistors. Each one has a different property, and therefore different uses, as explained in step 8 and 9.
There are much more than PNP and NPN, MOSFETs are transistor (metal oxide semiconductor field effect transistor) not to mention MESFETs, HEMTs and other less common varieties.

I've never heard of different types of transistors than NPN and PNP, and the transistors I've listed (i.e JFETs, MOSFETS, IGBT's,) What other ones are there?

Asides that, this guide was intended to show things that a hobbyist, or someone interested in electronics would use, not some obscure parts that a hobbyist would never use, or come across in a normal circuit.

And MOSFETS are technically transistors, yes, but they operate differently than bipolar transistors. Hence the different category, but I get what you mean.

Yeah, I'm just pointing out that you can group NPN and PNP under "bipolar transistors", but you can't group just those together under "transistors" since there are so many kinds of transistors.

Other interesting types of transistors are MESFET's and HEMT/MODFET, and HBT's which are made with group III-group V materials like GaAs, InP, and GaN. They are used mainly in radio applications, also power electronics and extremely high speed digital circuits. HBT's are also made with group IV elements, i.e. Silicon/Silicon Carbide alloys grown on top of each other.

Huh, interesting. I don't think I'll or anyone on instructables is ever going to come across those types of transistors unless they plan on building high speed digital circuits and stuff.

I'll keep it as it is, but thank you for your suggestion. smile

And what about the ISFET? Link2

My chemistry major roommate mentioned that. It is certainly a transistor!
