Who knows how to wire a lamp?
I'm thinking of making an actual lamp out of popsicle sticks, but I have no idea how to make the part that lights up. I know I need a lightbulb, but that's about it. Any sugesstions?
Pic is me. Robots can get past your captcha now.
>lamp out of popsicle sticks
are you 12?
anyhow, you need a bulb socket, a switch, wire and plug
I'm not 12. You're about seven years too low. But these lamps can go for up to 5000 dollars at auctions and I thought it was a cool project to try.
Thanks!

Hey /DIY/ I'm looking to make a hand crank power hammer, now this is my first design so be gentle, but I just need something that will save me time working metal while also giving me quality results
>>1043518
>hand crank power hammer
You mean a normal hammer?
>>1043528
A hammer drill if you will, hand cranked instead of electric powered
>>1043518
What is this supposed to be?
Only hand cranked hammer I could think of would be a spring loaded hammer with a ratcheting crank that releases the hammer at some point.
My son is designing a hover craft the size of an air mattress for school. He has two leaf blowers installed to it. Both are electrical and need to be plugged in to wall outlets, one is a 3-prong and the other a 2-prong. He wants to make or otherwise buy a power source for the leaf blowers to run off of so that the hovercraft won't need to be plugged into the wall in order to run.
Car batteries are out since they are too heavy. We had considered doing something with lithium ion batteries, for example hoverboard batteries that have a 36V charge, but I don't have enough electronics knowledge to be of any real help and apparently his teacher is far less helpful.
Any ideas?
>>1043479
>hoverboard batteries that have a 36V charge
get three batteries
hook in series
connect to leaf blowers
>check blowers first to assure will operate from dc
>>1043479
Does it absolutely have to be cordless for a school project?
And why are gas powered blowers not an option?
get a second hand walk behind blower off craigslist for cheap.
It will have more than enough power to lift a hovercraft, and when your kid is done with it, it will be useful in the fall
So /diy/
I came up with this idea to put a solar panel inside a cone to not only harvest energy from one side of a solar panel but from both sides
Maximizing the total energy harvested
what do you think?
Won't the sides of the cone cast a shadow?
>>1043476
not if you're pointing at the sun using the solar panel as a guide to point to the sun you can also automate this by programming a sensor the follow the sun.
>>1043475
so instead of using one side of a solar panel exposed to the sun you use both sides + a cone so you get half power on both sides?
Hey /diy/!
I'm searching a method to etching my pcb...i'm in italy and ferric cloride can't be sell...any soluion?
Sorry for bad joke at end lol
You can use hydrogen peroxide and hydrochloric acid to etch
>>1043458
Copper chloride. By far my favorite. It's extremely cheap, works well, and never needs disposal.
http://techref.massmind.org/techref/pcb/etch/CuCl2.htm
Would this work, or will the efficiency be terrible since the charger requires 100-240v?
>>1043449
Entirely possible that the charger simply won't work. Most switching supplies like that require a minimum of ~80V.
Just get a 6V/12V charger and us that instead. Just make sure it's switchmode, not linear.
>>1043451
So you're saying a higher voltage charger will have a lower minimum input?
btw, thanks for the fast reply
Hey, so I've got no talent for this.
I had to get my front wheel off, it was stuck and I didnt a rubber mallet or anything decent to knock it out with, so I used a screw driver and a wrench to punch it out.
The screwdriver ended up damaging the threads of the axle and I couldnt get the nut on anymore.
So I bought a thread file and cleaned it up, however it only goes half way in now, I've repaired most of the damage but on one spot on the far end it's slightly thinner, the outer part of the nut can't get past it by hand strength.
Any ideas how to fix this? the thread file isnt really fixing that minor fault, the inner part of the nut goes past it but the outer just wont.
Trying to put the outer nut part in first, it wont turn more than half a turn, right when it'll pass that thinner area.
Any advice is much appreciated!
>>1043415
go buy a die of the right size & pitch
>>1043429
tried to look for one that fits at the locally, none of the stores got one in the right size. would need to order and prefer to ride this weekend.
wouldnt it work taking a file and lowering the first line of the thread, where the nut wont pass by?
>>1043435
i'd clean off the thread, put marker all over the thread, then put on the nut as far as you can. take off the nut and do your work with the file carefully where the marker is worn
Hi /diy/ - is it safe to plug two surge protectors into an extension cord? I was told not to plug a surge protector into another surge protector, so I was wondering if I could instead plug them both into an extension cord. Would this be safe?
>>1043399
The problem with plugging a surge protector into something besides a receptacle is that it might result in too much load on a single circuit, which may result in the wire heating, melting the insulator, and causing a fire.
>>1043399
yes its safe... but you can simply plug the extension cord into the surge protector and achieve the same result
It depends entirely on what you're plugging into it. If it's all low-power stuff, you can load up a bunch of shit into it. If you want a fridge and five microwaves next to the pool outside, you're gonna blow the breaker/fuse
Post your most recent projects.

hey i'm actually trying to build something like this for rear surround sound speakers right now, but it can't it can't get it even so it doesn't wobble; it stands up okay but it's uneven as hell and ugly - any insight?
>>1043393
My first one did sway quite a bit actually. I opted for MDF over the scrap particle board I was using which made the bases a bit more sturdier. I'd recommend you sand the bottoms and the tops of your bases and both the tops and bottoms of your inner posts to make sure they're flat. It's also vital that the posts are all exactly cut to length. If you're using screws, use more than one on each post as it just creates a pivot point otherwise. Eventually I opted to glue the posts which I probably should have done in the first place. Since these speakers are about 10 kg each, you can imagine that it swayed quite a lot. Hope that helps.
Wouldn't it fall due Vibration and stuff?
Not sure this is the most appropriate place but here it is anyway.
For several days now my toilet has been clogged to some degree (voilently ill for days, unable to plunge it sooner) and now it's completely unable to drain no matter what I do.
Plunging endlessly is beyond hope and can't accomplish anything other than putting a vile liquid on my floor.
I have a bacterial drain cleaner but it does nothing because I can't flush it to get it to the clog further down.
I got my hands on what I'm fairly sure is a toilet snake but either it's not working or I have no clue what I'm doing with it. I just can't force the damn thing down where it needs to go and I REALLY don't want to have to stick my arms in that completely full bowl.
Would something like drano work even though I can't possibly flush it without overflow?
As for the clog, the bowl has a fair bit of fecal matter but I'm fairly sure there's a wad of toilet paper further down somewhere, possibly along with some amount of seeds. (I flushed a pound or so of poppy seeds over 3 or 4 flushes and didn't notice any trouble at the time.)
Basically I need any way to get this done without calling a plumber. I'd also appreciate advice on (SANITARY) ways of getting some of that water out of the bowl so I can work more vigorously without splashing.
In the meantime I'll see if I can get my hands on a better plunger. Turns out I wasn't using proper technique. pic unrelated
Do you have a wet/dry vac? I think I'd try sucking everything out, then removing the toilet bowl to get rid of the bend, and either pour cleaner right into the drain or try to clear it with the snake or vacuum.
Something seems kinda off about your whole situation, though (Poppy seeds? Can't call a plumber? Uh huh), but that's none of my business.
Trying to keep the people I'm living with (my parents because I'm disabled) from knowing I made poppy seed tea (basically a legal narcotic) a couple times recently because it would cause problems even if they realize I'm not an addict.
Not to mention that it just plain stinks soon after you're done with the seeds.
I don't look forward to the smell it would put out while working but using my Shop-Vac is a great idea. I'll go buy a better plunger before I try that because I think my cheapo one isn't getting a decent seal.
Part of the plumber deal is not wanting them to find out about the seeds that may or may not be in there, but I also don't want to burden them more than I already do, especially for a problem of my own doing.
If nothing else I'll rip out the toilet myself on one of my relatively good days.
>>1043379
I'm all about DIY. but when it comes to this, just call in the pros. Theyll get it done faster than you ever could.
For fucks sake the other anon is suggesting removing the stool completely. Thats a lot of work you can fuck up if you don't know how to or can't fix it afterwards.
Not to mention youve been sick, the last thing your immune system needs is to be fucking around with the sewage parts of your home.
Dad bought a used shaving brush in some flea market from a stranger. Was in shit condition, I peeled and sanded down all the varnish from the handle and put a dark + clear coat of new varnish and it looks great now, I'll give it back as a present (pic unrelated, camera broken ATM).
But how do I really sanitize it? I always bought new, myself. Hot water + soap + vinegar isn't enough for some stranger with possible AIDS and anthrax or whatever; will tiny diluted amount of bleach risk the varnish and/or whiskers? How about alcohol? How far can I push these? Any tips from craftsmen/shavers would be welcome.
Also, it's not badger, maybe boar (or something else). My dad just liked its shape and it cost him like 3 Euro.
Soap and water. Are you a lunatic hypochondriac?
>>1043368
>Are you a lunatic hypochondriac
Yes.
But also, would you pick up a stranger's shaving brush, just dip it in hot water and use it on yourself as-is?
If he only got it for the shape of the handle, just completely replacing the knot(the hair part) is your best option. The Golden Nib sells a few grades of badger, and I believe the have boar if you want to stick with that. Badger is softer, doesn't require soaking before each use, and works better, but some people like a stiffer brush, so they'll take the time to break in a boar hair one.
Alternately, hot water, soap, and vinegar is fine too clean and sanitize it. Even the real nasty shit can't survive out by itself for more than a couple weeks. You could probably check if Barbicide is safe for the hair to work in, or if that or alcohol will check up the finish you gave it, but I don't know if it's even needed.
Bought a couple engines on busted pressure washers. Will be mounting 24V and 12 volt automotive type alternators. I have watched all the youtubes (knurlgar prolly most intelligent) anyone done this? Is there a direct mounting option that will last? IE; a claw coupler rated for 3600rpm high torque or is belt drive the only way to go? Is ther a site you use for pulleys, woodruff keys etc? Pic related, (the ONLY commercially manufactured gas powered DC charger). But its 800 bucks and long lead time (from Oz)
I need high amperage as possible doing LiPo battery research (have patented BMS under my belt)
>>1043351
>the ONLY commercially manufactured gas powered DC charger
heh i saw a $20 800W gas powered generator with a 12V 30A output this weekend. must have been 20+ years old.
>>1043351
Belt drive. 100% easier to make and maintain.
>>1043372
Would agree. You could use a shaft coupler but it would be a lot of work to set up and you would need to make a shaft adaptor for the alternator.
I'm looking for project ideas in which an x-acto knife is the primary tool. I remember hollowing out book when I was younger in order to store my prized baseball cards. Anyone have any suggestions?
You can carve wood.
Or cut your femoral artery.
you can carve wood, soapstone, make a chess set for example, i remember when i was a kid i made a chess set from soapstone, though you should be careful not to drop it cause it's very brittle and soft, also you can make miniature ships with balsa wood i believe they sell kits like those but you can just buy the balsa strips and build your own design
>>1043301
I like the idea of carving balsa. I loved balsa wood airplanes when I was a kid
Get a new fridge.
Plug it in and listen to the soft hum as it comes to life.
Suddenly a low inconsistent scratching/sucking/rattling noise begins.
It just keeps going and it starts working on my nerve. Manual says that it could be the gasses and is normal. Usually settles. Fridge is leveled.
Been 3 days now and is driving me insane. Can hear it throughout the entire apartment. People tell me it's so quiet, but it works on my nerves like listening to a dripping tap.
Didn't think something so inconsequential would annoy me so much. Do I cut my losses and just return it or wait it out and see if it eventually goes away?
After 3 days i wouldn't wait for it to disappear. Do you have any warranty anon?
>>1043237
Check the freezer drawers and see if something is loose, I had a terribly noisy fridge until I shifted the cold packs I had in the freezer around.
>>1043237
get a white noise generator, make your own, and/or get a mic and speaker setup near there and cancel out that noise.
Hey /diy/
I have been wanting a Raspberry Pi-like for a while, but since it's so fucking expensive where in my country I decided to make this a personal project and build my own. It obviously doesn't need to be as powerful/beautiful/compact as the Raspberry Pi itself.
The issue is that I don't exactly know where to start. I am not a total layman, I got some electronics knowledge, a robotics background (mostly doing simple stuff like line followers etc) and am majoring in EE (first year though) but it seems that this is some other kind of monster.
I would appreciate any tip regarding the path I should go, the things I should learn (I love to learn stuff by myself!) and the stuff I should do. Even if your tip is "/diy/ might not be the place for that, you should try ___", or some suggestion of website that I could visit.
Thanks in advance and (the usual) sorry for my english. I might not have that many errors but sometimes I don't know how to express myself properly.
>expensive in my country
Auto fix'd.
Going to cost you more to make than import.
But if you still want to, start with the requirements.
Obviously USB.
HDMI?
Ethernet?
WIFI?
Linux?
And no idea how you're going to solder any kind of decent chip manually without experience.
Unless by "Raspberry Pi" you mean a generic dev board in which case it's a whole lot easier.
>>1043115
This will cost more than its worth by several orders of magnitude.
If you cant afford a raspberry pi then get an orange pi. And if you cant afford that then you got some serious problems mate.
