How hard would it be to build a "space suit" I don't necissarily need it to be so tight it can operate in the vacuume of space, Just enough to keep the Canadian winter off my face. Climate control like heating and cooling and ventilation would be a plus but not totally necissary.
as for heated clothing, this is something i have actually researched pretty extensively and it's not really viable unless you have a ton of money to drop on expensive Li batteries or you're also using a vehicle like a bike or a scooter. If you have a powered scooter you have an essentially infinite power source from the alternator / generator. Otherwise you're going to be lugging around huge batteries or paying out the ass for Li-ion and still having to carry quite a few of them to get any decent heating time. The heated jacket itself...

hel me out here please DIY dinosours i found a misteri on a metal forum from spain and i cant find this company and what its the disc for. aditiona information it come in a box of stuff when buy a lathe, the disc is hard bery hard so any one ?
Hey /diy/, I am troubleshooting these old speakers that look like hubcaps. Right, so their sound started cutting out at maybe a third of their max volume right after the house circuit it was on had some difficulty grounding itself. Pretty suspicious, so I thought that the power supply had been damaged. I wanted to test the system with my bench power supply but found out that it takes 13VAC 5A.
I have not seen many electronics that take low voltage AC so this is new. Where do you even buy replacement transformers? All I found was Ebay has this a halogen transformer at... Comment too long. Click here to view the full text.
>>918518 Ye but as of now I have no idea how to go about it, any ideas as to how I could spray paint designs without it getting sticky? I was thinking regular spray paint with some stencils then using a final coat of matte spray to make it smooth and shiny. Dunno how well the plastic would look and feel though
TELL US OF YOUR PROJECTS! TELL US OF YOUR EXPLOITS!
in other news I have a wired programming question.
I have a rotary encoder that'll be reading tens of thousands of revolutions at a time and a device which will send signals at irregular intervals. I need to record and export the number of revolutions(to the single or half revolution if at all possible) between signals(and between startup and the first signal) onto an Excel spreadsheet.
does anyone know of a good Arduino to Excel interpretation and recording software?
Do you need the spreadsheet to be filled out in real-time? If not, Excel is capable of reading text-based files just fine. I think if you give the file a .csv extension it might just work automagically.
Does the Arduino have a counter circuit? You might need to buy one to work with the encoder.
I want to build a waterproof diy 3ft ship hull out of wood with an integrated camera to livestream my local coastline, how feasible is this? What can I do about range? And will an electrical engine work with such a big hull? What kind of electronics can I salvage at the local dump?
>why not a rc heli/quad It wouldn't feel the same especially on still waters like at the lake The build needs to be able to be controlled with high waves and bad weather so it doesn't get lost
It's all about the waterproofing. Wood boats have very tight joint tolerances, so I wouldn't suggest that unless you are an experienced woodworker. Consider carving a block of styrofoam, then sealing it with bondo if that does not describe you. Range will be affected by the drag of the hull, the capacity of motor+battery you put in it, and the efficiency of the propeller you use; so find an RC boats guide and research best methods. RC boat expert does not describe me, so I stop now.
>>924053 >how feasible is this? It's not exactly rocket science >What can I do about range? It depends on a multitude of things, but you shouldn't expect more than 2km for controller range. It mostly depends on how you want to solve the streaming though, if you want to stream from the boat directly via 3G or some form of Wimax, you're not likely to get the 3km range. If you stream video using conventional 5.8G methods, then you upload the feed... Comment too long. Click here to view the full text.
I would consider my skills and available tools/materials, come up with a construction, and use google and the stupid question thread when issues arise. I'd go through several design iterations, considering various advantages and drawbacks of different methods. Eventually I'd settle on 2-3 variants that seem promising. Only after that I'd present my plans to /diy/ and make a thread asking for feedback and posting pictures of my progress.
But I don't have a dentist's chair, so it's more of a hypothetical thing.
>>922744 I'm not a fridgie, but that seems legit to me. Why not mount the hanger for the evaporator assembly between the fans though? It's dead space anyway in terms of airflow and will make for a much more compact unit.
"Digital thermostat + Display" = some sort of remote controller?
>>922747 I've got a digital thermostat that runs off 240V and has a 240V relay controlled by some kind of microcontroler with a thermister. Basically it just lets me set a temperature range (HiLo or LoHi) with a digital readout rather than relying on the analogue thermostat.
I originally bought it to put in a fridge that was misbehaving, but now I've just got it laying around.
The odd offset design for the window unit is to minimize the length the pipes have to be and the distance the window has to be... Comment too long. Click here to view the full text.
>>922744 do you already have any components? the design seems fine but the details are in the physical characteristics. what size evaporator? what size condenser? what size compressor? Are your condenser fans sized correctly to maintain an adequate high side pressure? why are you running 24v fans when you have 240v supplied? are your evap fans sized to maintain proper suction pressure and superheat?
also, you don't need a 'moisture trap'. they are used mostly on refrigeration systems and not necessary on... Comment too long. Click here to view the full text.
Dunno whether to post this on /k/ or /diy/ but basically very soon I'm coming into possession of a Martini Mk. III
I want to hang it up but all the 'gun racks' I find on the interweb are either for like 5 rifles or tacticool. Considering I want just the one rifle and it is an antique I'm thinking of some kind of wood and/or brass hook wall mount thing - but I don't know what to get or make one from scratch
