Hi /DIY/. I was wondering if you can offer a little advice on my costume. Basically I'm doing a classic robot, complete with cardboard boxes and that flexible aluminum tubing (basically like pic related). I'm building a couple of things to make it a more realistic robot, eg flashing LEDs, robot voice box, etc. I want to include a couple of motorized functions, which is where I need your help. I already have an arduino uno and two motor sheilds.
First motorized function is to make the head spin all the way around. Keep in mind this is basically just one cardboard...

IMO easiest way to achieve the spinning head would be to mount the motor on top of a hat or helmet, and have the robot head be attached to the motor and not attached anywhere else on the costume.
>>889800
That's a pretty good idea. I can mount the electronics, including the motor, on top of a helmet. How much motor, and how much battery would you think is required? I was initially thinking of wiring 2 big 6 volt lantern batteries to make 12 volts that would last all night. I was thinking mount the batteries in the chest and run a pair of wires up the back of the neck to the helmet. I was thinking of a motor like

Does this seem like enough?
Tig Welding student here. 1st month, I have 3 to get the trade. Any suggestions you guys can offer would be appreciated.
yeah, Aluminum over heats too quick. Keep a rotation of practice pieces going so you do not keep practicing with a too hot piece and you get a different weld each time
I'm currently trying to walk the cup and its a bitch
patience... seriously.
Rotate between 3-5 pieces you have set up. If your instructor says anything... explain why. You will actually spend more time welding rotating pieces than to stop and let shit cool.
When you get fucking pissed...which I am sure you will; take a break. Smoke, get a drink, do push ups.
If you are doing fine precision work avoid stimulants....like coffee.
Smile.Take you licks and fuck ups in stride and bury them.

Don't know if I should post this on /g/ or here, so I'll try here first.
In this hypothetical scenario, let's say some people do some really bad shit with a raspberry pi. "Bad shit" meaning hack a bunch of banks, remotely set off some bombs, run a massive child porn distribution network, or anything else you can use a small, cheap disposable computer you can buy with cash for.
What are the consequences for the other legitimate users of the raspberry pi and similar tiny computers?
Do you think we'll see some outright bans...

>sensationalist news articles about the
stop right there. nobody in the news is going to know or care what that circuit board is or does. I think the closest historical analogy is GPS units which what, get banned in 3rd world countries worried about spying? another similar situation is lab glassware: there are a few unenforced restrictions but it's trivially easy to buy whatever online.
The Pi isn't suited to any of those tasked you described. However what it is good for is attacking wireless networks. Get a small container, add a PI and a battery and you have a mobile hacking machine that costs less than $50. Produce a ton of them and drop them all around the target you want to hack. Government has already explored this and as such they're invested in it. They won't place a ban.

let us not forget clockmed. "misunderstood genius" will come to mind. although if they are discovering rpis then I assume that they will go off as successfully as the unabombers many shitty bombs that never did anything or only took a few fingers.

why do hams get so buttblasted when i fart and burp into my baofang handheld transmitter during their sunday meetups.
Bonus- is there any group of hobbyists more autistic than hams?
>>886467
4chaners. Read yr post, it should be pretty obvious why....if I was trying to talk to someone and kept getting cut out by some dumb shit....
keep doing it though, fcc might come to your birthday party. I've been listening to hams look for a couple of guys around my city, got a couple last year, turned them over to the fcc.
diy anons, I need some ideas.
I bought a house with gas furnace and electric water heater
I'll switch to a gas water heater quite soon
The furnace's intake is a short pipe drawing air from inside the house and I'm pretty sure the water heater is based on the same principle
First step would be to route both intakes through a wall to make them take outside air
I'm sure this will improve the efficiency a bit and (lack of) humidity a lot in the winter
Because I have some time before the cold weather comes I started thinking about improving...

Problem with your idea is it will not pass inspection
>>886444
don't they make int/exh combo tubes?
>>886444
what inspection?
terrible news gang, i "accidentally" punched a hole thro my wall.
imma gonna hit up the home depot and truy the "California fix" (according to yt)
if anyone has advice or tips on this id apprecuate it a lot
gonna bump with TES morrowind photos for a few post, will dump if yall help me out big time
>>886289
gonna selflishly bump with a few morrowind pics
>>886291
c'mon guise
just a little pointers would be appreciated, porb one bump after this then i'll just give up and go to home depot
Cut hole.
Cut drywall same size as hole.
Tape, mud, sand.
Paint when dry and flat.
Watch paint dry.
done.
Hey /diy/! Any sample code for Arduino light switch?
https://lmddgtfy.net/?q=arduino%20sample%20code%20for%20a%20light%20switch
Try Github?
Hey /diy/, how would you recommend I cut this where my fingers are? I have access to a metal shop but haven't been in there for about 4 years. It's stainless steel.

/thread
With a hacksaw.
so.. I just found this but the charger doesn't work and I was wondering if I could make it usb any tips? warnings?
also this I think it might be important
Probably the easiest thing would be to just cut the wire off the charger and solder it to a male usb to make a cord.
>>885812
Charger is 5.2v, usb is 5v
Should be no problem with just cutting the lines and splicing them together
i need a good idea on hween costume for school contest
believe me this doesnt have to be a 100$ + costume all i need is somethign original
the school isnt very original most of the costumes are bought in regular stores
last year a kid that had costume made out of boxes and foil as well as metalic tubes for arms and stuff made out to look like a robot won
so you can see that much materials dont have to be needed like iron man suits and shit ya know?
comment ideas if you can thatd be great
>>885770
What the fuck is hween.
>>885771
Halloween
how do you not understand that?

Hi, my bike is kind of broken
When i use it the pedal falls of, i foud out that the nut fell of and i put it on again but it keeps falling of
Im thinking about soldering it directly but im not sure i give your advice
Here's a pic of the nut
Take the nut up to your local hardware store and grab a matching size locknut
They have a little insert that grips on the shaft to prevent it from backing off
>>885590
Are the threads undamaged on the nut and the bolt? If they're not, replace or repair the threads.
Alternatively, get a lock nut, or pour locktite all over your nut. Not sure how long that last solution will last.
what are these used for? can I strip paint from wood with them?
also give me general advice on renovating my room by myself.
>>885534
yes they can
general advice: wear safety
>>885534
grinder brushes are for removing stuff from metal. they will damage wood. (you may *want* that damage for a weathering effect, but anyway)
the normal way that you strip latex paint from wood is with a heat gun. you heat the paint up a couple hundred degrees (until it begins to form small bubbles on its own) and it softens enough that you can just scrape it off without any chemicals
>>885534
You're better off using a heat gun and sand paper.
Wire brushes would scar the wood a piece of piss.
sorry if there is a better place for this, never been here before
Is there an easy way to get the picture on the wood?
>>885378
Works on wood.

>>885379
thanks! I'll pick some up and try on some scrap wood first
Any welders in da house?
how much would you charge someone to fab and weld this frame???
Have you figured the cost of materials?

Material supplied.
Only interested in fab costs.
