/diy/ - Do It Yourself

Neat.

Does it work?

As for me, I made a crosscut sled for my tablesaw, and it wasn't square, so I gave up and went home. Typical.

oh, just stuff.

>Does it work?

Yes, but it isn't instant and you need a torsion wrench of course, these pics are just showing the rakes.

Anyone doing any DIY today?

Dumping some MOT Welder pics.

This one came from here,

It seems the big copper secondary winding is a copper tube with copper wire inside.

Man, I wish I had all those transformers!

Nice looking build here, but I'd be afraid of overheating.

Looks like this instructable uses the capacitors from microwaves too.

Damn, I dumped in someone else's thread. lol sigh...

fixed and put in proper thread: >>143661

I made some soldering tips today. They seem to work fairly well. I need to make some more for my smaller-tip soldering iron. Pic related.

What is this?

>>143977
Not to be a dick, but I pick a lot of locks and have been doing so for a couple years. A lot of your rakes seem like they will get stuck in the lock. Nothing sucks more than putting a new pick in and getting it stuck in a lock and having to leave it there or break it off. To fix this make sure your slopes between peaks are not to steep. I would recommend not making them any more than 50 degrees from the horizontal.

It is one layer of a mechanical filter assembly for a grating spectrometer.

>>146023

exploded pic of the individual parts for the whole thing

>>146013
Noted and thanks. It's my first set of picks and the metal would sometimes jitter and the Dremel would take more that it should have. So, it was a battle of simply learning the material and how much could stick out of the vice to prevent jittering. I have like 500 strips of that metal, so I can just whip up more if needed. I haven't had them stick yet, but I've only picked like 10-13 locks with them.

I need to actually print out the templates I have, but I haven't got around to that.

>>146023
Ah, I missed what the stuff was on the left side. I take it that diffracts light then.

>>146031

Naw, it's just the filters for the incoming light so I can split out a clean first order diffraction by band. Hoping to test some of the setup with a real grating tonight.

>>146034
Damn dude, a fucking spectrometer. You should hook that shit up to a telescope, mount a nice and powerful green laser on it and point it at rocks to figure out what they're made of from far away.

Nice to see a use for that toothbrush other than sex-toy for girls. It sucks as an actual toothbrush.

I finished building my Zvex Wooly Mammoth clone today. It's a guitar pedal. Tomorrow I'll be painting the enclosure and putting on the decal.

Pic related, it's the shitty decal I made.

>>146214
Just sayin' - Why don't you bind the encolsure in faux fur, you know, like a friggin mammoth? That will give the word FUZZ-BOX a new meaning (inb4 YIFF IN HELL). Long-shaft pots are a must though, you don't want any tangling.
Also, do you have a metal shop in your area? you ccould get your logo in aluminum or plate steel. That'd look really badass.

I'm in the process of making a vent hood for soldering, plastic welding, Dremeling, etc. Basically, for anything that causes fumes or smoke. This is what it looks like right now. The box in the window has a fan from a microwave which sucks air out of the big box and spits it outside. The electric cord for the fan runs through the venting. That's a dimmer switch I have currently hooked up. The brown metal is the case top off a huge microwave.

I plan on adding a 24" shop light in the top of this and boxing it in the rest of the way. The front will have plexi glass. The light will have a rocker switch and there will be one plug in outlet on it for electric tools. My hands will go under the plexiglass on the front. It's kind of like a blast cabinet without the gloves. I plan to make the plexiglass slideable and adjustable. That way it can be fully closed, fully removed, or partially open. I may end having a second piece of plexiglass with rubber glove attachments so i can do some small sandblasting or whatever. Once done I'll paint it all one color and maybe put up some often used charts and diagrams inside.

Nightly bump.

Fixed an alignment problem in the adjustable slit mechanism, I can mate it to the filterbox now.

Head formed.

Now we lay out some optics on the dining room table and see if the optics math is ~ correct before building the next few pieces, but have to wait until the housemates are done with dinner

Nice dude. Keep it up.

Working on this sonofabitch with my team, if that counts.

>>147685

Oh yeah, that counts.

>>147688
Cool.

>>147690
Is dat some Torg and Riff?

>>147696
... no, that's a partially constructed robot.

Optics just laid out on the table, nothing encosed; one of the lenses kept rolling off while I was trying to take the pic. But... the math looks like it's correct.

Compact fluorescent spectrum.

Got the kalman filter on my quadrotor working and in the process of trying to find some decent PID values.

>>148038
That's awesome.

>>148048
pics?

R2D2 style droid to wander around my desk while i work. Most of the drive systems are out of him, i'll prolly start a thread next time he's in a more assembled state

..really should get a working digicam and get better than mobile phone quality snaps too..

oh, and a wireframe C-130, but this has been kinda neglected for the bot

>>148297
Damn cool.

>>146767
I missed getting stuff to finish this since all the stores are close, so I just whipped up some cardboard, plastic wrap, and a CFL to hold it over until I get the stuff to finish it. I've been do all sorts of work in it and it's been a dream at removing the fumes from anything I put in it. I can't wait to get a good light and glazing. working with it now allows me to redesign a few aspects to make it far better.

How are you guys preventing the chassis from twisting? It looks like it'd be easy to bend if another robot smacked into it or it fell off the bridge.

>>148038

Just working on understanding the math tonight... random pic while playing with objectives.
