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...

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...

a lot of AC devices will work fine with a DC input coz they're just gonna rectify the AC anyway. so you can use your bench supply, no harm will come to the amp.

although you will need to adjust the DC voltage to about 1.4x the AC voltage to get the same effect, so use 18Vdc.

TELL US OF YOUR PROJECTS!

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.

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...

How would you made pic related from an old dentist's chair?
6 replies and 1 images submitted. Click here to view.

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.

I've never worked on a refrigeration system before, but why WOULDN'T this work? I've got a friend who does plumbing so he has most of the pipe bending and fitting tools I'd need.

Obviously excluding the fact that it isn't time or money efficient compared to buying one prebuilt. I have a feeling there's some major flaws with my design but I don't know enough to spot them.

DESU I'm probably not going to do this in case I fuck up the seals and asphyxiate myself.

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.

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.

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?

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

Buy a five rack and slice off four racks.

Also, be sure that you are aware of your local display laws. In Canada, the weapon still ahs to be secured somehow, and not displayed with ammunition.

>>924533
Most of how they're designed means it wouldn't look very pretty (even if I did a very good job of cleaning up after) - plus it'd be wasting money buying a large rack to chop it up

The martini as its so old counts as an antique so it can sit there quite freely - until I load ammunition for it but that's a different matter

Make a gun rack from a deer rack. Deer antlers are pretty cheap and look classy. Here's a rack on ebay that's a matched set. It currently has no bids, and is only 15 dollars.

One word of warning though deer antler stinks while you're grinding it or using high speed saws. Apart from that, antler is a perfecy diy material, and would look great with that rifle.
