hey /diy/ ive go some EPS foam (kinda like the stuff in the image) and have to make 4 miniture sculpture like peices/models that represent hierachy, chess pieces ar out of he quesion, I was temted to do differnt stormtrooper helmets,but they would be hard to carve with only a file and sme sandpaper, pls help guys??
>>920501 pick up a hot wire foam cutter to get a rough shape of what you want to make and then go from there. You can get one for about $12 USD that takes 2 D batteries, but it is limited on how deep you can cut and how big of the piece of foam you can cut. I use one for when I cut stuff out of 1" to 3" pink insulation foam for molds when i cast stuff out of aluminum.
So my family tugged on the hose out the front of our house one to many times and the copper pipe the tap is connected to developed a tiny crack. To save myself the trouble of a plumber I decided to borrow one of those little propane torches and redo the joint that cracked.
Propane wasn't hot enough and only just melted 10% silver braze so I went and got MAP gas for the torch instead. As I understand this should be hot enough. The braze melts fine but solidifies as soon as it touches the pipe and refuses to wet it.
I've had this thought for a while of just going off and buying some land and building a small house just to get away from everything. To live almost completely off the grid. I don't need much, just the basics. How would I go about doing this?
Just loosely thinking about it I would require the following:
1. A stable/robust residence. (I'm personally thinking a log house of some kind)
2. Something to generate power. (A bike generator + solar. Know it doesn't generate much, but I don't need massive amount of energy to run lights and a computer, do I?)
3. Something to eat. (Potatoes are easy to grow I hear and can be cooked in a few different ways)
Is this unreasonable to achieve, am I missing something essential?
Please share any tips, tutorials and videos on the subject.
I recieved a Tokoyo Flash RPM a couple of years ago and over time it's accumulated grime underneath the glass covering. I really want to send it back to the company to get it repaired and what-not, but they won't do anything since I don't have the original order number.
Have any of you dealt with a watch like this? I'm afraid to take it apart because It's not exactly the conventional watch. I've looked online for other people taking it apart, but cant seem to find anything on the internet.

Well, I went out a few hours ago and sat on a massage chair. The way the chair put pressure on my calves made me wonder if you could make artificial "muscles" which worked with air. Once I got home I googled "pneumatic muscles".
I've been reading about them a bit but I'm not an engineer, so, /diy/, tell me about em. What are they commonly used for? I also read the proper term is PAM in wikipedia, is that also used as the common name? And finally, would it be possible to make a prosthesis which felt closer to an "actual" leg with them?
If I remember correctly, those are really hard to control accurately, which is necesary for any type of artificial limb. Plus, you need a compressor to move them, making a PAM prosthetic very unwieldy.
>>921066 human muscles work in pairs, your brain has a feedback loop that controls proportionally the extension of each muscle to move and hold in the right position.
if you fill an air muscle with air it would go from one extreme to the other. you would need to control dynamically the pressure in the 'muscle' to set the position and then adjust it continuously as you change the outside loads and forces.
sup /diy/, I've been through some parents stuff and found some audio equipment I remember we had when I was a kid.
I found this soviet Vega 323 stereo turntable among other things. I'm wondering what to do with it since it doesn't work properly. Dad says it's a piece of junk anyways because it's rough to the LPs. The audio quality isn't very good either because low quality needle (although this could be replaced). But apart from top acrylic cover it's in great shape visually, nice wood and lacquer, plastics are nice and solid too. I thought I could build a home media center in there after I gut it.
It also comes with a pair of speakers which are shitty, maybe paper membranes. But same nice wood and lacquer and textile front mesh. I thought I could replace the speakers inside with something of higher quality.
As a product of era that didn't plan obsolescence, it comes with complete schematics so it could be repaired to original state... possibly even upgraded to produce higher quality output if some components are replaced but I wouldn't have use for LP player anyway.
Sup diy, I have a solar 2135 mig welder that belongs to my dad, he bought it new 18 years ago but it has set in storage for the last 8. I want to get it working because it will do up to 1/4 inch which is impressive for a portable welder. But I have two problems. 1) the charger was lost a few year ago when we moved (24 volt charger unknown amperage) and I have no idea what condition the battery is in. I have included a pic of the welder and I was hoping if anybody knew of a site that sells new chargers or how to make one. Pic related, the welder
any 24V SLA charger will do the job. a used e-bike/mobility cart charger for 10 bux is more than enough. cut the end off, splice on a cig plug and off you go.
it probably needs a new battery, after sitting flat for so long it'll be unrecoverable. open it and see. you'll probably find it's very simple inside, basically it's a spool gun grafted to a jump start pack.
>>920550 Can you explain? Is it possible to somehow link two displays together like a dual display monitor setup for PC, and offset the main signal enough to one side so that half is displayed on each? Then just lengthen the controller cables?

I do metal work with a little wood work but my dream is to run treasure hunts. I've done a few before that ran from one single website but I wan't to create something different, something you have to solve on the move.
I want to do scenarios like kidnapping and people have to follow the clues to find the victim, it'll all be light hearted, but I need ways of getting across clues, the move basic is QR codes, which... Comment too long. Click here to view the full text.
>>919999 Can you describe the problem any better? Does it do absolutely nothing, or just not what you want?
Your code doesn't look right. The LCD only has 16 characters per line but your text strings are 26 chars long with more than half of them as just as white space. The text is only going to be visible during the first half of the printing loop, and this goes by really fast. (250 microseconds per character)
Hello. I have been trying to get a respirator. I also need a mask as I will need to protect my eyes from metal and wood shavings and stuff. So I was looking if there were masks with respirators built in but not like a full face respirator. It would also be nice if it looked cool.
