Huh, I thought "recently finished" or similar threads were frequent here?

A thread to post whatever /diy/ thing you've finished.


I got an audio recorder for my camera a while ago, and today I found an old ikea lamp just lying around.

Remembered I had an old tiny cheap tripod being useless as well.

Voilá, a desktop mic stand!

I need to get my hands on some more material so I can have the small tripod head rest in a rubber mount for further isolation. And then another tripod head at the bottom of the stand itself, so I can mount it on an actual tripod, the whole thing without the heavy foot.

I have to add a proper volume control, audio input and the screws that fix the top to the enclosure.

I had to shield the cables with a steel mesh from a coaxial cable (from tv cable) to avoid the AC noise.

I just finished a micro lathe made from trash. It is powered using an electric generator I made from an old exercise bike (that I use for many things). I use a Dremel to mill the wood instead of chisels. I'll be using it for making very small fishing lures later on.

The Dremel does the cutting instead of using chisels. Thus, there doesn't need to be very much torque on the lathe motor. However, the harder I pedal the more torque is applied. I could make a set of micro chisels that would work with it. Using the Dremel cuts time to mere moments for micro lures and I don't need a rail to rest it on.

This need some small improvements, like frequencymeter doesnt read lower than 2V amplitude.

There's a lot of nice stuff ITT, /diy!

>> No.1114900

Have you considered using an acetone vapour bath instead of sanding down the 3d prints?

It smooths out the printing lines really nicely with little effort.

>find a container large enough to go over the top of your 3d printed thing
>stick an acetone soaked rag to the top
>put it in a tray with a few cm of water to seal in the acetone vapour
>pull out your print when it looks about half smoothed and leave it to dry

Just make sure you print in high quality abs plastic and a see through container would really help so you know when to open it. A small fan to circulate air would be good too, just make sure the fan and the container aren't made from abs plastic for obvious reasons

Started this old lump before Christmas, then ran out of abrasives and polishing compounds halfway through doing it with all the stores closed, so I couldn't get back to it until recently. Pretty happy with it overall, I murdered about 2kg of potatoes and onions with it which took some of the polish off the blade itself as it began to form a patina from the acid, but a good result- holes break the vacuum holding the food to the blade and nothing stuck to it which makes me really happy after ruining 2 shitty drill bits on making them...

Also took the time to do some Engine Turning on the stainless bolsters, something you don't see done very often any more but it has a nice refractive effect.
That took a bit of experimenting to find something that would work, ended up using a modified, mini steel polishing brush (hooray, found a use for the fuckers!) with a sleeve put over it to hold it together a bit better and automotive diamond cutting polish. Stuck it in the drill press and ground away.

Looking at all your guys stuff is so inspiring. I always have some project ideas kicking around but what I've found is I usually never get to them because lack of funds. Considering I'm a university student it tends to happen more often then I'd like.

How do you guys fund your projects, is it just extra disposal income or do you guys make mini budgets or have a pile of potentially useful parts?

i actually finished the lamp 2 days ago and started a dwarf tomato plant seed the same day, it only sprouted yesterday and will be moved to the black container today, its basically a kratky system, meaning the roots of the plant will be submerged in the nutrient solution and as the plant grows and drinks up some of the solution the water level drops and top part of the roots are exposed to air while the bottom roots stay submerged, making it unnecessary to have an airstone constantly aerating the water.

Well its an LED bulb and while it does get hot its never so hot that i cant touch it, so i doubt it'll burn anything, also the woven cover is just a plastic pot from ikea that has that straw weave glued on the outside, so theres no real risk there.

For lowest budget project ITT. Only thing that cost money was the packing tape, alligator clips, filter (could just use old sock), wood clamps (not really needed,) and two 1watt LEDs. Everything else was salvaged from old electronics or from trash. Most of the electronics are reusable for future projects too.

Such things are great for prototyping. Starting your project is more about inspiration and the will to actually start it. The only things you really need are tools. Some of which are used to make other tools.

Those modules are great. I've got the 15+15w out in the garage, with my old Rasberry Pi playing a continuous rotation of about 30G of mp3s through some shitty speakers I threw together.

I've also got bunch of the 3+3w waiting for me to figure out what to do with them. I'm tempted to try a wifi streaming thing using an ESP-32 -> DAC -> amp and have whole-house sound.

Here are the shitty garage speakers.

I'm poor and I move a lot for work. So I wanted furniture that could stand up to the moves. Having to rebuy walmart stuff was getting expensive. So now I save up to build nicer things at a higher cost, but they'll last longer, plus my furniture specifically fits my needs. The downside is is that it takes a lot longer to unpack because I've not built everything yet, but it should be easier come the next move.

P.S. I'm the one that built the DVD cabinet.

i was about to buy the 3+3w module, but it cost almost the same than the 15+15w.

I still need to make the speakers. I'm thinking about buying VW speakers or using two speakers from a Yamaha synth + two tweeters

I will need something for my workshop so i might build another one with bluetooth so i can use my phone to play music

I think I got the 15w amp for 60 cents and 5 of the 3w were a dollar or something like that. I bought a whole buttload of cheap crap all at once a few months ago, so I can't remember the exact prices.

When you don't need it right now, aliexpress is a gold mine of stuff.

Yeah, sadly the motherfuckers of customs here the charge you everysingle possible tax that they can. So in the end is no so cheap and/or they won't give you your package if you're suspicious of "comercial activities" which seems to be anyone.
