Hey /diy/
What are the actual limitations on making myself a powered exoskeleton? I realize its not really all that feasible, otherwise it would be done more often, but I am interested in finding out where the bottle necks on development are.
I'm mostly doing this just to get more familiar with robotics in general and my robotics club at my university are on board if I can get a decent idea for one, which I don't think is a given.
Power could be inelegantly solved by a two stroke motor. Its going to be whiney and annoying but it would work. Could...

>What are the actual limitations on making myself a powered exoskeleton?
Learning machine code and making powerful motors, then programming them to move in tandem with your body without breaking any of your bones.
>>905128
This is completely relevant and an important part of what I'm looking into. Are there any preferred programming languages for robotics in general or could python do it?
>>905131
Try to stick with C. Also, machine language may be very important to be familiar with here.
How do I reach Richard Proenneke's level?
>>905057
>implying you can
>you can't
he was on a level above us mortals, he faked his death so he could start over somewhere even more inhospitable. he's probably living in an ice castle somewhere deep in the interior of antarctica
>>905057
You dig about 9 feet into the ground
To get above his level, you don't hang your snowshoes over the fire place, use stainless steel to cook with not aluminum, put your cheap junkie rubber boots away from your bed. Then get a chubby native woman to cook and keep the cabin in shape.
Stop what you are doing.
Post a pic of your breadboard, now!
No shortening of the jumpers for the photo!
mine is lost lel

i mostly just solder on protoboards.
i hardly ever use my solderless breadboards.
Grow lights? I live in a cu.ckshed in the city and need the Oxygen and cheap vegetation. Any thoughts or tips for a noob?
i just use shop lights, works well if you keep within 8 inches of the plant
>>904218
Get yourself a few COB LEDs, reflectors, computer heat sink + fans and make yourself a light.
>>904218
What are you growing?
You can grow plenty of indoor plants without any supplemental lighting.
Spider plants
Philodendron
Palms
Ferns
Ivy
Snake plants
Dracaenas
ZZ Plant
All of these plants are happy to live their life inside with whatever light they're given.
Dracaenas like the Cast Iron plant and Corn plant can only be hurt by overwatering. The ZZ plant is also very indestructable.
Vining philodendrons do just fine in poor soils and need only water and a light feeding once or twice a year.
What the cheapest way to get fleas out of my house and off of my dog?? I'm a poor fag and can't really afford the expensive exterminator
>>904046
Torch it. That's always a cheap option.
>>904046
to start with, get either a flea collar or other flea treatment for your dog.
then, treat anywhere the fleas could be with borax, then vacuum.
Vacuum really well, and tie off in a bag so that any eggs don't hatch. keep vacuuming daily for the next week, and possibly reapply borax, and you should eventually kill them all. Obviously, you'll need to wash the bedsheets etc. if they're in there too.
Option two, is wait for winter cold, drain the water in the house pipes and flush toilets empty,...

I will give this a try, will borax hurt my dog?
I want this dining set but it's almost $3,000.
Is it possible to build it for less than $500? Can I take the picture to a carpenter and have them cut all the pieces I need? I have zero woodcutting experience.
The steel frame will be much more complicated then the simple wooden top. You need around $1000 worth of tools to build this.
>>903823
Yeah, but if op already has a welder, hacksaw, and angle grinder, plus a table saw for the wood, he could build a similar one for ~200, depending on what wood he uses.
>>903823
Lets not shit on it just yet..
OK, you gonna need someone who can weld, for starters - as >903823 noted, this bit is not for beginners, nor cheap to start with. Then, we need a bill of materials:
FRAMES:
2” steel profile
Table needs about 300" ?
Bench (x2) needs about (220" x 2) = 440"
so, 750" 2” steel profile
WOOD
1 x 60" x 30" Maple (Table top)
2 x 54" x 14” Maple (Benches)
FEET
4 rubber (Table)
8 x height adjustable (benches)
FIXINGS
?
- Just getting you started OP, go google up the raw material prices, and, post links.
No finishing costs (wood, metal) there either, mind - maybe, time you are done, $3,000 aint as bad as it looks..
Hey /diy/
Was looking for some guitar pedals to buy at first, but I tought it might be nice to build one myself.
Is anyone experienced with those kinda electronics here or have some tips on where to start?
>>903606
are you completely new? as in no soldering experience and no electronics know how?
buy a compete kit in that case.
meaning pcb with components and a detailed guide.
pedalparts.co.uk is good for that.
that said, many effect pedals are stupid simple, many of the "classics" have less then 20 components.
I've built many pedals both on pcbs and protoboards.
many guitarheads learn as they go, but i have an electronics background.
>>903618
I can solder pretty well, and I've a basis of electronics, but more in the direction of simple circuits to controll dc motors in arduino projects. That's kinda all I made.
Thx for the site btw, the only diy pedal boards I found online where overpriced.
Do they also explain what circuits do what with the signal from the pickups?
>>903624
I would like to understand how the circuits deform the signal the way they do, haven't found a good source on that online.
Black and Decker Matrix. Will it fly into pieces of shrapnel when used a lot? Do the snap on tool ends work enough for home DIY and random sorties of light work?
>>903590
>Black & Decker
You know it's going to be bad, but it's just so much cheaper that it might be worth it.
Here's the deal, if you buy from a bad manufacture, you are buying bad tools.
If you want quality tools that you won't ever need to replace, don't buy a multi tool system.
>>905002
>Black & Decker
>bad manufacture
Yeah, buy DeWalts... but don't look up who owns them.
>>903590
I bought a Matrix corded drill when it was on clearance for 15$, just to have around as a beater drill or to drive light screws.
I test drove some 1 1-2 inch wood screws through cheap plywood into a 2x4. Clutch seemed to work alright.
I will probably never buy any more attachments though.
FWIW the Lithium one is identical to the rebaged Craftsman Bolt On which has been clearanced out. You may be able to find them cheap somewhere.
If you want to use the stupid multi tool thing, youd be...

Are there any carpenters? Tomorrow is the first day on the job as a Carpenter helper. I've never had a job similar to this and have no knowledge of the trade. I have a proper shirt, pants, and steel toe boots. What else should I take. They never described what to take.
>>903059
Have some PPE gear. Safety glasses, hard hat, gloves, ear pro, and a safety vest. May be overkill, but you'll be about as prepared as you need to be minus the tools. Tools being hammer, cats paw, measuring tape, carpenter pencils, speed square, and torpedo level. Basics of the top of my head. Next level is a worm drive skill saw and a nail gun. Then your own compressor. Really you just need safety stuff and basic tools for now.
>>903059
Good luck btw. It's kind of a shit job, especially this time of the year, but I do remember those times fondly. Work is much more complicated now.
>>903059
Bump.
Looking for advice, just started researching today on youtube but would appreciate some advice from some anons .

You'll need more ventilation than you think. Humans transpire a shitton of water, and it will make your van smell like a gym sock from a hooker's ass.
Why are you living in a van? Why wouldn't you live in your house?

Who /silkscreen/ here?
Sorry about the terrible pics. I'm not a photographer, but I've got a little empire going in my kitchen if anybody wants tips or tricks to do this efficiently and economically as a fun a profitable hobby.
>>900378
I'm a relief printer.
I tried screen printing with disastrous results this summer.
Does not take a whole lot to get started, and you can make art prints, stickers, t-shirts, and practically anything else flat, hundreds of copies in the course of an honest day's work.
I want to make my 4 year old son a wooden sword. For playing silly buggers and not much else, what would be a good wood for this?
>>896838
poplar or tulipwood as yanks call it.
cheap, hard enough for silly buggers, and you can sand/ carve it easy and itl take a paint finish if thats what you want to do.
you could go onto maple/ash but that is probably a little overkill and doesnt carve or shape so easy.
>>896838
Hopefully he won't split his friends heads open.
Woden swords can cut, break little bones and stab.
You're a bit of an unfit parent if you think this is a good idea.
Use vinyl or soft plastic for the blade and pommel. You know, bendy stuff, still he could put an eye out.
>>897207
you are a massive pussy
who generally electronics here?
>I'm new to electronics, where do I get started?
There are several good books and YouTube channels that are commonly recommended for beginners and those wanting to learn more, many with advanced techniques. The best way to get involved in electronics is just to make stuff. Don't be afraid to get your hands dirty.

How much voltage do I need to drive this power mosfet

Honestly the datasheet makes no goddamn sense to me.

Any advice on how to drive it with 3.5v
So, I'm one of those who got drawn into electronics via drones, and I've found that there's a lot about soldering and the various connectors to learn about.
I do believe that this is a deep enough and different enough topic from general electronics to warrant it's own thread.
Anyway, here's one of the better writeups I've found on the topic if you're learning.

>>890703
Weller irons are already less than $20, how cheap are you looking to go?
My understanding is that cheaper soldering irons sacrifice temperature accuracy. If you're not working on anything too delicate (thin PCBs or tightly packed sensitive components) then any old soldering iron should do the job.
But I don't solder much. Take that with a grain of salt.
>>890707
>Weller irons are already less than $20
I'm more talking about things like:
http://www.amazon.com/WTCPT-Temperature-Controlled-Soldering-Station/dp/B00004W463
got a bargain on a wsp81 on ebay. i think the model is discontinued but tips are plentiful and the unit is real sexy.
weller is pretty much universal
other brands definetly depends where you live.
e.g. i never heard of hakko before /diy/
Thread that contain small insignificant questions that don't need their own threads, here is a thread where they can all go.
>>895059
Can /diy/ tip me some methods to destroy a fair amount of letter-papers without having a paper grinder ?
Any lawnmower or something ? Letting it under autumn rain ?
>>895061
Burning is obviously the easiest. If you have a good fan over your oven you could throw them in there on self-clean.
>>895061
Burning it ? It'll probably be annoying depending where you live but we ain't in summer anymore.
People in my area burn fallen leaves in late Autumn. Pretty sure it shouldn't be a problem
