oh, this thread again.

Internet ist full of sites for diy pedals, but nvm...

if you want to clone just a pedal, use google for the schematic. if you want to modify a pedal, youre welcome.

if you really want to create a new pedal, lets go - thats the real stuff.

i guess you got all the tools and the skills (soldering etc.) too.

my first own - created pedal was a digital lowfi one; i took a vocoder - ic in dip-housing, created a buffer, soldered all together and voila.

most analog pedals are created yet, fuzz, dist, overdrive, buffer, boost - there is little to no room for innovations. so what do you have in mind?

>>942968
I've made a fair bunch of pedals, but nothing like that.
can you name the IC?
sounds fun.

>>943538
IC is HT895.

Haven't you been paying attention? Rock tumble quartz into dildoes.

Very interesting video op but you'll probably have to be more specific. All of them have very different techniques used to build them. It would probably be easier to hit up a junkyard and make your own than to try to recreate his instruments.

>when I measured amps the multimeter went through the roof

Never do this. Your multimeter measures current by checking the voltage drop across a resistor of a few milliohms. Putting the probes directly across your battery is almost the same as shorting it which can cause overheating and explosions.

> Is there a risk for the batteries to explode in my pocket or backpack?

The LiPo and LiIon batteries used by hobbyists often have built in overcurrent protection to stop meltdowns, but it doesn't sound like yours do. Without protection power wires just lightly brushing against each other can weld themselves together. I had some batteries glow white hot and burn through my workbench before I had time to grab safety goggles and wire cutters. I was planning on putting those batteries right next to my skull in an LED helmet.

if you mess you LiPos, you can get a fireball in your pocket. just disassemble everything and throw it away, then thank Zeus you're still alive.

So if those 2 solder points from pos ans neg wires from picture were to touch each other everything will go to shit?

>>942131
I don't think I have ever seen tools quite like these. You are probably the type of person who should try metalworking and welding as a hobby.

>>942131
I made a ghetto shank out of a hack saw blade and some hockey tape, but that's really not worth a picture

I also made a thing that we call "the tool", its a piece of quarter round taped to a piece of baseboard for extra length, about 18' long total, for cleaning eaves troughs that I can't reach the end of

Comming here because i don't know where else to ask.

My Xbox360 wireless receiver for PC recently died after a few years of use. I searched around and it was most likely a fuse. So i soldered across it, and now it works again.

However, i dont want to fry my USB ports.

Would it be better to plug it into a USB hub -> PC? Do most standard cheapo hubs have a fuse?

our company took on a job of reconditioning an old SCR control system for an oilrig a few years ago.
really old shit. diode matrix cards, relays and everything.

we bought a small batch of metal cap lm741's
they where all good and legit national components, so we ordered much more from the same supplier.
like half of them failed in circuit because the offset pin did nothing, and we had issues all over.
a colleague pulled the cap it, it was a smaller brandless metal op-amp with national cap stuck on top. almost like in the OP.

So I did what I should have done originally and put this on a breadboard before trying to solder it all together, and figured out how to get rid of the high frequency oscillation. Instead of trying to fuck around with a bunch of caps for local feedback in the voltage gain stage, all I needed was one from the op amp output to the inverting input (C6). -3db fall off is right before 20 kHz, but since it's a bass amp wired to a big woofer it's unlikely I'll need nearly that high response, even. I also had some pretty heavy DC offset on the output (150 mV), but that was solved by lowering R17 from 100k to 10k. It's going to be driven from a crossover with more 5532 op amps, so lower input impedance shouldn't be a problem.

providing its from at least last financial year they wont give a shit.
just tell them your mother sent you the shirt and it had the tag on it or some bullshit.

Nice try, Tyrone.

Thank you /diy/no

If you don't need the shelves to move that is an absolutely rock solid way to do it and you should have no qualms about using that technique.

Fuck that. Just make a pinhole camera. There are lots of tutorials, and all you need is something to put the camera inside of or behind. Here:

On second thought, after rereading your desired specs it seems what you need is a wireless webcam. Put some tape over the light that comes on when it's recording, and put the receiver in your computer (one of the unseen USB ports in the back of the computer). Log into your profile (or the hidden admin profile if you're running WinDon't), get it all set up, then jump back out to the login screen. Tada! Not exactly /diy/, but I'm sure if you hang out a bit longer someone with discrete component knowhow will pop in and help you out. This place is a treasure trove of valuable-idea-people.

Heres the side i tried all the stuff on. So far the sanding worked the best

>>944861
Fill it with water
Put in a bucket full of water
Let it soak overnight
The label will fall off, like the labels on cheap shampoos in the shower.

Or get some goo gone.

And for gods sake stop sanding it.

Spray with baking non-stick spray.
Wait 24-48 hrs
Remove label, wipe goo with paper towel.

For small jars, I've had success with putting them in an airtight container (like a ziplock baggie) with a little rubbing alcohol. (1/8 cup or less). Wait a couple days.

There's another geology/mineral related thread here, everyone >>941473

Fuck no.

The blade geometry is completely wrong. Chainsaw teeth are very aggressive. They are designed such that they actually want to pull themselves into the wood (this is also why so much as grazing a chainsaw blade will land you in the hospital for stitches at best), and if you look at the links, there are small protrusions that keep them from trying to bite too deep.

You don't want this kind of tooth for stone. Trying to use it will get you nothing but some jagged nicks in your rock and a lot of carbide fragments You want far, FAR less material removed per tooth. something more akin to what you'd see on a hacksaw. Theoretically, you could make a custom chainsaw blade that had such teeth, but that would be horrendously expensive. Even if that weren't an obstacle, you run into the issue of stone getting into the blade's track and ruining both it and the blade in what will likely be a fairly short period of time. Not to mention the load of shit that will end up in the rest of the saw.


Literally everything about the chainsaw is wrong for cutting stone. Just isn't going to happen.

you'd need a rock chainsaw. and rock saw are usually used in sedimentary rocks since they're softer. 4-5 on mohs scale.

rock chainsaw are huge and mounted on rail.

otherwise you can buy a rock saw with a diamond blade and you can cut yourselve pieces of rock but they would be 1cubic feet max I believe..

might as well try carving your carpet

>>944979
No it´s not. Carving and stamping leather bases on the fact that water softens the leather and drying hardens it somewhat. Can´t do that with faux leather or with chrome tanned leathers. Only vegetable tanned leather is good for carving.

>>944979
Any embosing on faux (PVC) leather is possible by hotstamping it. But you need acurate temperature control and it's very easy to scar the first layer.
