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... Comment too long. Click here to view the full text.
>>889798 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 http://www.digikey.com/product-detail/en/324/1528-1062-ND/5022791
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... Comment too long. Click here to view the full text.
>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.
>>886628 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.
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...

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
>>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
