Get one of these fuckers, a deterrent on its own, can become lethal. Can run leftovers

cattle fencing
If they can steal it, chain it down or lock it away.
I also like motion sensitive lights. Crooks hate light. That and cameras.

You could plant rose bushes along the fence.
Natural barbed wire.

>>1170753
Your alarm company could probably add a sensor to your gate for not much.

Traps are illegal, even non lethal ones because they can't differentiate. You could put up a high voltage fence to keep your dog in maybe, or some spikes to keep birds from sitting on top of your fence, or razor wire on top of your fence because it's obvious and usually acceptable, maybe not in a residential area, check local ordinances.

Maybe you're exceeding the input voltage range of your ADC. Try adding a pot between the amplifier and your ADC.

>>1170467
A 500k pot would be enough?

Also, could I put a pot right after the 9V power supply?

I have tested it with a oscilloscope. This is the result:

>>1169981
yes, uv light is dangerous, the fume is dangerous, the heat is dangerous, but if you have to ask you might want to be super careful, and just remember, wear everything all the fucking time

>>1169984
Okay thanks man I don't plan on fucking around I take this very seriously

>>1169981
>My brother said that half the stuff you learn from the safety orientation won't be followed at some jobs
He's right.
So much safety measures are downright ignored for the sake of productivity it's fucking ridiculous.

Friend of mine owns an antique store. She had a store of one time she got a carpet guy to evaluate an old, large rug. The first thing he did was get down on his knees and smell it. He claimed that piss smells are basically impossible to remove and that any carpet smelling of piss was valueless.

Good luck, OP.

Go to the pet store and get an urine enzyme formula like Nature's Miracle. It is your best bet. You can rent an extractor too if you want. This will help to.

>>1169287

soak in enzyme

It looks like crudely cut cardboard that's been shoddily spray painted and slapped on a glove.

>>1169265
Looks like you worked pretty hard on that, Good job :)

>>1169265
it looks shit honestly

>>1168278
please.

Use tungsten carbide to line the outside of the container; inside as well

>>1163403
You can try to convert your bass signal into midi by making some random algorithm with arduino. When it come to experiment and weird stuff, everything is possible.

honestly, probably not.

synths like that are just one big circuit board, so unless you're gonna figure out how those little black blobs of silicon work and wire directly into 'em, then there's no chance.

some synths will do this though; check out Access Virus B (probably other ones too) - they have microphone inputs that let you input stuff like microphones/guitars and let you use all their effects/vocodors n stuff on external sounds (not just the internal sounds)

also try googling "circuit bending" for musical shit

have fun!

I know the fucker comes on here... AvE isn't bad, how about you just admit it, shit head?

Also Paul Sellers, Tubalcain, This old Tony (just for the throwback MASH voice and horrible Dad humor), and I think Myfordboy is possibly the best to watch for sand casting technique.

What is more lethal in an electric current, amps or volts?

>>1157863
current is what kills you. It's why stun guns and tazers do not generally kill people while they run 50k volts through them.

>>1157863
It depends on the situation and your skin resistance, if your body is dry it has about a 300Ω resistance, if it is wet through sweat it will be lower, down to about 50Ω, this is why people in showers die so much quicker than people with dry skin.
Also, when the current past the heart is taken into account, that will kill a person a lot sooner than just a shock to the right hand.

This one being the broken one, I can post more photos if needed

This is the only marks on it, it says 2A 220v AC. Please note that i dont have a voltmeter

Not too hard.

I got a cheap pair of video goggles and used an Arduino to generate and overlay a HUD onto the camera feed.
For sensors I have a geiger counter, compass, GPS, and gas detector.
The only real challenge I had was making sure my code didn't use more than the 4kb of RAM I had available (the video buffer used like 90% of it).

OP here. I have conducted a few tests of the power board. It looks like when I jump the PS_ON and SB_6V pins of the power supply, the logic board is only outputing 1.93V instead of the 12V it should be reading.

I've checked all the pins using the below video, and all are outputting around the same 1.86, 1.93 V when they should be outputting 5, 12 V

More than likely your psu
Only similar problem I've seen was a monitor which would do the on/off thing and that turned out to be a faulty switch with corrosion on it.

>>1172446
not just bulging caps you wanna look for burn marks and such as well. any damage really.

>>1172427
Finish it with sheet rock. And maybe some carpet or tile..

>>1172435
Carpet probably is most realistic, I've been thinking about doing that

>>1172436
carpet is just going to get fucked up, and that right quick. get some of the plastic faux wood flooring. the stuff that snaps together.

drywall it. 1/4" is cheap and you can easily hang all that area in a day.

>>1172302
Practical effects are best, how much pain can you tolerate?

of its a spoof, then you should have it in italian, with subtitles that are completely different to what's said in italian, and then go for proper 70's blatantly obviously red paint fake blood.

>>1172307
Not a lot :/

>>1172317
I do want it to look fake, and I do love the Italian idea, but I do want it to look semi-real. Kinda like an Argento or a Fulci movie

>Would the box survive the fire
probably

Fire safes are usually just drywall and steel, the at the door gap use an expanding material that seals when it gets hot.

The fire rating in usually marketing bullshit: they rate it at a certain temperature for a certain time. House fires can reach 3000 degrees with enough combustible material, but usual stay under 2500. Average time it takes to put out a whole house fire can be about 30 mins.

But the fire ratings are usually low; 1500 for 30 minutes is not comparable to 3000 for 15 minutes.

>>1172257
When fires get really hot and a good fire safe is used, the insides can still get charred from the heat causing irreparable damage despite no actual flame damage.

This is because of the high heat and low oxygen. If it's really Damn important documentation, he should scan to an electronic media and store it in a safety deposit box in a bank.

No offense OP, but it's just the better method than having a buddy make an amateur fire safe.
