I've been working on a small project to create grow lights -- i have some small LED panels with different wavelengths (660nm, 630, green, blue, deep blue), and a full spectrum PAR sensor to measure irradiance. I'm wondering about an economic way to mount these panels (they're small about 6 x 3 inches) but can produce a high amount of irradiance. I also have a big roll of reflective material.Planters etc for the soil I can source easily but i'd like to have an enclosure of some kind around the plant. Not interested in a tent-like setup I want something sturdy like a box. currently hunting around for junk like glass and plastic panels etc, pvc pipe, but thought i'd ask here. I'd like it to be fully enclosed so i can manipulate temp and humidity
>>2891603i only seed start indoors but my grow lights are mounted on eye hooks from the ceiling and i use 10x20” trays in 6cells with plastic humidity domes on topthey make big zip-up grow tents for dudeweeders
>>2891603I made one a few years ago from a piece of 1/2” mdf and scrap pine boards. Just a big box, lid and front hinged to give full access. Self adhesive radiator foil on the walls to retain light and heat and keep moisture away from the mdf. Also put a clear acrylic window but it needs a curtain of sorts or you’ll have weird coloured light leaking into your house all the time Anyway the lights I got have eyes on the top to run a cable through, it’s very useful to be able to lift them up with the cable as the plant grows. I guess you could put some self adhesive cable tie mounts on the top of your panels and then put cable ties through to get the same thing for very cheap. Then run some steel wire (or stranded electrical cable) through the cable ties and screw a few eyes into the ceiling

I coulda sworn there was such a thing as a speedometer that worked solely mechanically, no mags, weights or springs or air current.just translated speed of turning shaft into needle position.was I high and is that impossible, or is it possible but no one uses it for practical reasons.I want to be able to adjust suspension on vehicle in relation to speed, but also do so purely hard-parts mechanically, with some force.
>>2891439all seem magno, going back to 1900somehow I think it might be possible with something like thishttps://www.youtube.com/watch?v=mWJHI7UHuys

>>2891437>Thats how both the 80s dumpbody 3500s i had worked, think it was how a lot of the old chevys didThere are magnets and springs in old speedometers. Although those are both mechanical things, so I dunno exactly what OP is smoking...

>>2891433>I coulda sworn there was such a thing as a speedometer that worked solely mechanically, no mags, weights or springs or air current.Not really. The two closest would be the centrifugal speedometer and the chronometric speedometer.Centrifugal were mostly used on train locomotives. They used a set of spinning weights like a speed governor. They were relatively simple, but required regular lubrication and maintenance and basically fell out of use as soon as alternatives were available, outside of some niche roles (combined speedometer/governor systems).Chronometrics were basically a complex clock with additional escapement mechanisms. They can be extremely accurate, but they have a bit of lag. They can be built to be extremely resistant to vibration as well, which is why they were used on motorcycles up until the 1970s. But they quickly went away once magnetic designs improved, as they were far more expensive.Modern style magnetic speedometers were invented/patented in the early 1900s (1902?). They aren't as accurate as a chronometric, but perfectly adequate for most applications. And they're much, much cheaper.>I want to be able to adjust suspension on vehicle in relation to speed, but also do so purely hard-parts mechanically, with some force.It could be done, but it is going to be vastly more complex and expensive than using an electronic sensor to drive the controllers.
Are used compressors worth buying, or it'll probably be a ticking timebomb? I have an option to but an operable 50 liter/13 gallon 2 piston 3HP compressor for the equivalent of 80$ plus shipping. Alternatively I could buy a new 24L 1HP one on amazon for a bit cheaper, but the air supply capacity is only 55L per minute at 7bars, so I won't be able to use air tools. I don't want to spend more, because it's not gonna be used that often and I already have a 6L cordless 36V 8.5bar compressor for the airgun or the nailer
>>2891877https://www.amazon.com/ZHSYMX-200PSI-Suspension-Compressor-SILVER/dp/B0CQX1B6ZT?th=1&psc=1replying to myself this looks identical to the viair compressor but much cheaper. viair is likely just upcharging for doing extra qc on chang

>>2891889those bags really shouldnt use any significant amount of air. that just has plain old semi leveling valve for ride control?those wilmars are tanks. pretty well built and reliable. theyre a little too top heavy though especially when roading fullyou going to set it up with guidance?
>>2891908>those bags really shouldnt use any significant amount of air. that just has plain old semi leveling valve for ride control?>those wilmars are tanks. pretty well built and reliable. theyre a little too top heavy though especially when roading full>you going to set it up with guidance?Yeah I'm thinking once I get the leakage all stopped it won't really take much of a compressor at all to inflate what little bit it does need when needed. There is no current ride control on it at all. In fact it doesn't currently even have any onboard air. Just schrader valves. I'd like to plumb it all up and make life a bit easier though. I have read about guys using those air leveling valves to make them perform better. I think I just need to get it all functional first, then maybe add something like that at a later date after I get it in working condition. I doubt I'll put any guidance on it. Honestly it's probably overkill as a sprayer for me and way more than I need for my farm, but for the price and with it being somewhat local I couldn't pass it up. The cost of the sprayer was about half of what it would cost to have my farm sprayed once by airplane... I don't spray a ton right now and am getting away with using a 30' wide 3-point sprayer, but when I do have to spray I hate it. If I even just get the foam marker setup going again on the old Willmar and make it comfortable to use I will probably spray a bit more and not hate my life so much.

Hi /diy/,I'm thinking of making a potato cannon, but i have no access to PVC pipe ends. If i make a wooden lid, will it work? Does wood seal gas? I don't think i can make a very tight seal either, and i want to be able to fill it up and use it a few minutes later
>>2884688MAKE IT OUT OF STEEL AND LOAD IN AN ENTIRE CAN OF BLACK POWDER AND BALL BEARINGS LIKE A MAN. BROTHER
>>2887343Hairspray also gums the fuck out of the thing. If you're doing it for real, use gasoline in a body spray bottle for the true fuel injected experience and power.
>>2884688I've built a PVC potato cannon. use the thickes pvc you can get, do not exceed half the maximum pressure of whatever pipe you use. pvc will shatter and you will be a pin cushion if it bursts.mine uses compressed air and a irrigation valve as it is instant on. making one based on explosive vapors is for morons.
>>2887338I have an SCBA setup my dad got from fire department surplus store. when he passed away I kept it, it was in my shed for 5 years. one day I was messing with it, and that mother fucker had 2500psi of air in it. it was fully charged. I had no idea he had it filled. it took 15 minutes to empty.
>>2891655The worst part about those combustion based potato cannons is getting a proper stoic ratio so it actually sets off right.
Do i have to do this manually on every corner, every crack, every screw, every hole, every panel?seems like too much work, couldnt i just tape it or something?
>>2889003> what does it mean? RPM?It’s plaster. It’s softer than you can imagine. When you’re doing touch-ups, make sure your fingernails are short or you’ll gouge it. One single full rotation would probably cut a 1/16” into it.Most of your sanders are designed for wood.In addition, it doesn’t use sandpaper. It uses an open abrasive mesh so the dust can flow through.we get back a couple of pounds of dust.the vacuum has special multiple-layer filters.
>>2889003> should minimize the risk of doing a lot of damageYou wouldn’t use a sander unless you were doing something like removing a popcorn ceiling, and even that is going to be 99% scraped off by wetting it first.The finish plaster can be re-wet, and just scraped off in case of major fuck-ups. sheetrock 60, less so, but still that’s the way to go.

I want to remove the grip from this knife to either refinish or replace it, but I'm not sure how to get it off. Is there some way to remove these fixtures cleanly, or will I just have to drill through them?
>>2891064those are rivets, they'll need to be drilled and replaced. they also often use a coat of epoxy under the wood to seal the gap
>>2891064remove the wood first, those are not salvageable and need replacement anyway. Then you'll be able to tell whether just clamping and using a punch will do the trick for those rivets or not. Various sizes of brass or stainless steel rods are available all over the place to replace them anyway.
>>2891064As the others said, best to just drill them out and replace. Brass rod is cheap and easy to work with, basically just cut to length and hammer the ends
>>2891064>I'm not sure how to get it offimagine failing, before you even started.
>>2891064Try sanding and refinishing them first. If you are happy with the results you saved a bunch of time. If you hate it than remove the wood by prying it off or using a chisel to break it off. Than saw off half the rivet and press or hammer it out. Hammer it with a drift pin.
I'm looking for something make out of a pen blank (I have a bunch). Asking for some creative input! Ideally a puzzle or something like that, because I'm not good at drawing or painting, and those things wear away pretty easily from repeated handling.
>>2891303Yeah but then how do you make the pieces move the way they're supposed to?I suppose I could move it by hand... do people still make manual chessboards?
>>2891160Those look like nice hardwood. You could make good dice with them. Or do a locking puzzle like pic rel
>>2891303I'm thinking more about things that are three-dimensional, like the blocks in OP that wrap around the block.A chessboard isn't a bad idea if i combined the pen blanks side-by-side, but each one is a different wood (it was a sample pack) and it would look a tad strange.
>>2891413Maybe you could drill some thru-holes and cover the groves with glass to make a 3D ball maze puzzle
>>2891160Pens? You could make them into pens.

I'm also applying to a lot of defense industry positions, so it's not even like the jobs are being competed for by foreigners because it's all held under ITAR. The only people I know who are actually getting offers are the black people and the women (and my background is objectively stronger than any of them), so what the fuck.>>2886848this too. I don't recall ever having an interview and not being offered a position afterwards, but I can't even get to the interview stage at this rate.

Hi diy, I posted this before in /adv/ >>>/adv/32636875 and someone there gave me a tip to search for tutorials and post here, here's the issue:>I live in this place which was a warehouse of my relative, he moved out of the city so he let me stay here for free, and gave me freedom to break/repair stuff.The place is made of bricks and cement, and I got people to make some basic living stuff (some water connection service and electricity stuff), it was cheaper than paying rent somewhere else (and this place is near my current job). Recently some tiles suddenly started popping out violently (like if some giant worm was walking under the earth), and I'm not sure what should I do. This doesn't seem to be the first time this happens (there were some broken tiles in the attic), and I'm not sure if I should just let them be or what. I asked before and it seems they have been there for like 30 years, but there are other tiles in the restroom which haven't popped out at all, so I guess there was some "bad quality work" there or something (I'm not sure anyways, I don't know stuff about construction). What would be the best course of action to do here? I'm not sure if I should try to remove the pyramids formed by the tiles. I can clearly see the cement under them now.I got this image from the web, but it kinda looks like what happened.Some anon told me it was due "expansion" and that's something new to me (I'm really ignorant about construction and haven't tried reparing stuff before). I'm not sure which kind of tutorial would be good for something like this, and I have seen some just using some tube thing with some glue like stuff, and I wonder where should I actually start, for example, I don't know if it'd be the best to remove just the loose tiles, or somehow try to remove every tile to "make it all over again".
>>2891588They popped out because they were installed wrong and there's humidity coming from your foundation. there's no easy way to fix this
>>2891593Thanks for answeringI suspect that's the case, there's humidity coming from the walls whenever it rains (at least it doesn't come into the house, it used to be united to another buiding, but the owner decided to separate it, but the ones who put the wall may have done it wrong because a waterfall forms on the other side whenever it rains.So, now I know it won't be easy but... Are there any chances I may be able to fix it without knowing a thing about construction?I guess I also have the option of "removing the tiles and leaving them aside" if it's way too much, and somehow search for "professional help", but from what I heard, most of the local people working in this kind of stuff, do it wrong (like in this case), and I'm worried this may repeat soon, so I want to know which knowledge I may need before doing anything so I start cramming it up to try to fix this.
>>2891596maybe try and get the water away from the building - eavestrough, a bit of grading etc...
>>2891598there's not actual water coming inside, or in that part (as far as I know, it was fixed somehow because some dentist rented the place so it got fixed because it was an issue), but maybe it was already there since long ago. It has been kind of cold these days, and I'm not sure if that may be related to what happened. I'll try to get some tools recommended in the other post ( hammer and a wide chisel) and try to remove whatever I can (not all the tiles moved). I'll try to update my progress if this thread is still alive after I try that.
Looks like the perimeter expanded (wood?) and it got warmer causing the tiles to expand too.Needs an expansion gap between the edge and the tiles at a minimum.Also, you could use caulking instead of grout, possibly every second or third course to act as an expansion joint.
