It's a shifting spanner.
Many of the 19th century ones had a hammer function built in (any tool can be a hammer - a hammer can be any tool).
My father had one that wasn't symmetrical like OP's. It was hammer one side and spanner the other.
If you look up Adjustable Spanner on Wikipedia, the first pic is OP's "French Key" and the second is my Dad's "English Key".
Thanks, OP. I learned something today.

Isn't it better to monitor current and voltage characteristics to see if one light source is about to blow? Tricks like that are used to monitor magnetrons so that you can replace them before they blow.

In that case you could install a KiwiSDR with a long antenna that would emphasise the lower parts of the HF band, probably well into LF. Might need traps to reject MW broadcasting stations swamping the ADC though.

Guys, I need to make a machine to practice table tennis without playing against a human opponent. I want to beat all my friends in actual matches eventually but don't want to let on about my growing skills, hence the need for not practicing with people. So far all I can think of doing is playing against a wall or maybe a taut latex sheet to create a little more delay and variety in the return compared to a hard surface. I'm trying to replicate this style of play: https://www.youtube.com/watch?v=vIOn7F6o7NA
My question is do you guys have any better ideas than what is essentially a stretched out balloon as an opponent and if not where do I buy large sheets of latex. Thx in advance.

So I'm in the very basic planning phases of building a hidden bunker beneath my house. I'm a not limited with equipment because the main thing is I don't want anyone to know it exists. I'll go over specific plans in follow up posts -and please point out problems with the plan so I can correct as I've never done a project anywhere near this scale.

But my main issue is air. I need to figure out a way to get air down there (more than ten feet below ground) that would be completely hidden and inconspicuous. I've seen a fee underground air filters but they're all in the 10k range which is definitely a purchase large enough that there would be a record and would tell any interested party I built an underground structure at somr point.

Ideas? It wouldn't be as simple as rigging up a ton of pvc pipes with fans inside them would it? I feel like that solution would probably require a complicated powering system and there must be some obvious reason it wouldn't work. What cpuld I purchase to put inside the bunker to monitor oxygen levels?

>on craigslist

failed.

with enough resources "they" can figure it out. Subpoena craigslist server records, correlate IP addresses from the block owned by your regional ISP, or even subpoena the ISP for all of the IP addresses in your city.

Its easy enough and can be narrowed down based on time.


The safest way to deal with this is hacked Wifi + proxy list. I suppose you could use TOR, but the problem with TOR is that its basically a system of chained proxies utilizing widely publicly available servers that are already major magnets for law enforcement.

Your best bet is to get software to do your own proxy chaining and to modify the proxies you use constant.

Couple that with, ideally multiple, cracked wifi or public wifi and you are probably OK.

>>1463951
"don't choke the fan down" yea it's a bit more complex than that. You need to match the air resistance of the filter to the static pressure ability of the fan. Propeller style fans produce almost no static pressure. You need a squirrel cage or centrifugal blower.
Shop vacs are NOT meant for continous use and WILL overheat and burn out VERY quickly.
The redundant breaker thing was a good idea.
>>
>>1470189
Public proxies are shit for privacy. Rent some VPS's and set up your own VPN's with modern obfuscation techniques. Also use tor but set up your own guard nodes on some VPN's. Connect to all of this with an isolation proxy, one for tor and one for the VPN.

Yagi antennas are easy to build. It does take attention to detail though, since the elements have to placed with 1/10 millimeter accuracy
>>
>>1470189
What if a burner phone bought with cash was used to set up the transaction to buy a separate cheap laptop specifically for use with proxies which would also be bought with cash never giving your name to the person it was purchased from and most future purchases would be made at places like Home Depot with cash but what few had to be purchased online would be done only using bitcoin and purchased through proxy on that specific laptop which wouldn't be your main one so even if people came looking they could be given a different computer to search which never even used proxies.

I have +-60V, drive signal is there, i get output on amp (sine wave, gain and everything works) but one mosfet is getting hot and second one is cold, what could cause that? Drive signal is around 3.3V, gate resistor is 4.7ohms, both signals are identical. Is it becouse i didn't put all 8 mosfets in? Each mosfet has its own gate resistor and diode. Should i maybe get different mosfet or modify mosfet driver?

I'm in england man, all of our exterior walls are brickwork, when we frame walls the roof is already on and covered in and you're marking on a nice dry concrete floor, we just lay our sole plates down and space them off the nearest brick wall with the tape or do the layout with a straight edge and pencil.
The roofs we do are a mix of truss with hand cut hips, jacks and valleys, the truss timber is normally 3 x 1"1/2, depending on the roof the hips and jacks are normally 5 or 6 x 1"1/2. Was always taught to hand nail birds mouths as it's stronger than gun nailing.
True, a hammer will do it, but in certain situations it's just easier to pull timber into place with a hand nail rather than, hit it into place, hold it and spike it.

I'm currently a NEET that dropped out of university since it really wasn't my thing. This was about 1 or 2 years ago I don't remember.

I'm 24 and I thought about learning a trade to have something to look forward to as a means to an income. The problem is that I don't know what trade would suit me. I'd like to balance out my interest in a trade, the average income it provides and how much exhausting it is.

I'd like it if you guys could recommend me some good trades, I'm quite intelligent and a bit OCD so if you know from trades that benefit from this, tell me.

Some of my traits are:
>attention to detail
>good managing resources
>like diy in general
>very focused if I'm doing something I enjoy
>can improvise
>good following procedures and improving them
>introvert
>assertive

Being a car mechanic is very good once you really get going. It will always have high demand, you get to work with very few people, or even alone and it also pays relatively well. Working as an electrician or plumber like some anon mentioned is also a good idea and given the nature of these jobs, maybe a bit better for what you described.

Looks like they have both a transmitter at ~315MHz and a receiver at 125kHz, anyone know what the receiver is for? The host car telling it when to send data (>>1469743)? Programming?

It says 5-8dBm, but since it has an external antenna there's nothing stopping you from whacking a BJT on there and amplifying the signal, ± impedance matching. But I'd give up on reprogramming it, I think you're stuck with the temperature, pressure, acceleration, and battery voltage sensors. Which isn't necessarily a bad thing, all that alone is perfectly fine for putting up on a high-altitude balloon if you boost the output power and manage to hide it from the feds.

All welding machines have a duty cycle. It may be 100% at full output, but that is still a duty cycle. And "duty cycle" is a general concept that applies to other machinery too.
>>
>>1470434

There are ready-made kits to do exactly that. I mean, you still need the gas bottle, hoses, torch, fittings, and all you get is the most basic TIG rig with no pedal, HF start, or any of the other fancy features an actual TIG machine will have, but it works.
>>
>>1468285
>Downslope, Upslope, 2T/4T
Irrelevant if you're using a foot pedal (because you're doing it all manually then). Upslope doesn't matter much (it can give you a bit of time to get the torch in position before full heat kicks in), but downslope needs to be long enough to prevent cratering or pinholes if you're using an on-off remote (buttoning works too, but a long enough downslope is usually preferable). With an on/off remote, 2T/4T determines whether or not you have to hold down the button (or MIG trigger) to maintain an arc. Generally, 2T is better for tacking, while 4T is better for actual welding.

>Pulse
Can help increase productivity and/or ease of handling. Not critical, but can be nice. High frequency pulse is good for increasing penetration, low frequency pulse is good for avoiding blowouts on thin material

>HiFreq or Lift
HiFreq is very nice if you can afford it, and necessary for AC TIG (aluminum) unless you get a true square wave machine, in which case you're paying a lot anyway. However, it can interfere with electronics.

>Arc Force
Can be nice for stick, but isn't necessary. Makes it a bit easier to avoid sticking, and affects the relationship between arc length and heat input.

>Pre and Post Flow
Most cheaper machines do a decent job of this automatically, but manual controls for this can save on gas or help in situations that need extra-long gas coverage.

Over 15 years I've taught myself how to play a bunch of different instruments. How do you teach yourself how to sing? Are professional lessons just vocal exercises or is there more to it? I'm pretty musically capable but I'm a trash singer and would like to improve.

Sorry if wrong board, it concerns developing a self taught skill so i guess it's fine.
>>
>>1469836
I learned how to sing as a church choirboy. I was already pretty decent because I had a lot of practice from singing along to 8-tracks of Van Halen LOL. But classical voice training will teach you useful tricks like singing from the diaphragm and holding notes on vowels.

I do think there are some people with hopelessly bad pitch, but clearly that isn't you if you've taught yourself a bunch of instruments.

Mind if I ask how you taught yourself keyboard? I'm in the opposite situation from you. I think my singing voice is about as good as it's ever going to get, but I can barely play anything.
>>
>>1470048
Not OP, but playing keyboard relies on music theory much more than instruments like the guitar, so making sure you know the basics can really speed up the process.

Just learn to like the functionality of the stock ones, if your actually using a dual sport bike for off roading your handguards are going to get beat to shit, fragile electronics will not survive, plus it's nice to be able to take off the plastic guards once it gets above 70 regularly, hell on both of my bikes I run them without the plastic more than with.

The beauty of the positioning of the stock turn signals is they're tucked away between the wheel and bar end when the bike is on it's side so unless you take a rock right in that spot they're pretty much going to be fine, if you move them onto the guards it'll be the first thing looking at hitting pavement.
