Sulaiman gorgeous work there.
I guess I could ramble about some of my home-made efforts but I'm sure it bores alot of people here to tears. All of these are posted on the boards
somewere.
I recently made a dispense only syringe pump (retract coming soon when I have time)
Made a rotary evaporator
Classic ATX AC->DC power supply
I also made mini-glascols for test tubes with nichrome and sheet fiberglass (not very useful) powered by a cellphone charger.
Made a short and medium wave UV Photochem-TLC lamp&housing
All sorts of stuff. I'm sure I'm forgetting more of it.

Very clever burette holder, Sulaiman. Are those zip ties?

Oh my, this one brings up memories...
My current hot plate I got from a community college discards pile.
Before I picked that up, however, there was this fire hazard

Where did you finr that regulator for the Gas bottle Magpie?
Is that a camp stove Reg.?
I love the creativity on this thread. Now I feel Much better about re- purposing items.
They tried to have me "put to sleep" so I came back to return the favor.

I found it in the BBQ section of a Ranch & Home store. I haven't seen one since. Avogadro's Lab Supply sells one like it (at an outrageous
price.)
Yes, I think its intended purpose is likely for a camp stove. Mine was about $15 ten years ago.

Smaerd, I love to see some pictures of your work. You say that they're trivial but i'd beg to differ 
I'd love to see all of those, especially that rotovap. I was just recently thinking to myself "how do I get me one of those?".

My latest haul. A mason jar (love those graduations), plaster of paris(shouldn't be here.. but my god this is so hard to find in my country), and a
hamster drinker, which is basically a test tube any how. It even has a glass protrusion making it ideal for generating small quantities of gas.

The qualitative analysis kit looks so cool, a list of reagents would be great!

Yeah, I have been trying to find one as well. I tried to see where Avogrado purchased theirs, but there was no getting around them.
For now, when I need a burner I just attach the burner's latex gas feed tube to the end of a propane torch, turn on the gas, and then light the
burner. It works, for now.

Click on the picture, and you
can read all of the labels. And yeah, I want to make one of those now too.
I have something slightly similar, in that I bought a rack of 25 centrifuge tubes for a few dollars and use it for storing small quantities of a lot
of different reagents.

What you first need to get is a book or manual of the qualitative analysis procedures. Qual analysis used to be a standard course in college
chemistry - I don't know if it is taught anymore because most professional analyses are done with instruments.
My procedures are in the college chemistry book by Holtzclaw et al. It's a separate section in the back of the book. Not all editions have it.
Once you have the procedures the list of reagents will fall out of those. Without knowing how to use these reagents you are just collecting - but
that's alright too. 
On the regulator for propane bottles - I tried to find a source for it too. The only information I could find was a company name in Mexico, which led
nowhere.

It's funny you should mention this - I found a book at a rather nearby library system called Quantitative chemical analysis, which was a textbook.
When I do end up checking it out, I'll look more into the above analysis kit.

That's a different course than Qualitative Analysis.
Quantitative analysis deals with procedures like titrations and gravimetric procedures that give the %, ppm, etc of a chemical specie.

A forum member asked me about small fiberglass blankets for insulating flasks during distillations, etc. Here's a link with a picture and linked
directions for making one yourself:

I just purchased 8 sq. ft from Amazon for $8.99 with free shipping from Rain Writer, one of the alternative sellers.

(others available in new condition)

EDIT: Be careful not to purchase the fiberglass mats that seem to not be braided, which I assume would not be very coherent and difficult to keep a
uniform covering.

Interesting. Is the use of Asbestos a totally bad idea? I know it's use isn't promoted now, but is it actually super dangerous, or just
treated that way?

Mostly treated that way. Personal opinion only, no data to back my thoughts up.
Do not breath its fibers and I think it is good to go.
I am too tired to research to back up my thoughts

It's actually not that terrible. There are still many older floor tiles that are made out of asbestos, the real issue arises when you inhale it.
Most wire gauzes still use asbestos, as I believe that it has rather superior properties and is cheap. As most chemicals, being exposed to asbestos
dust a few times is not the end of the world, it takes a chronic exposure to get asbestosis.

I have a friend that fought abestosis for decades. It sounded horrible.
Take that for what its worth. There is a shipyard around here were a lot of people were exposed.
If you get it, its pretty bad.

Interesting. Modern textbooks describe it as death incarnate. Vogel appears to have used it a lot. I'm pretty sure he lasted a long time.
