With a servo drive.

Hall effect encoder? If you just want speed, and not position, go for Hall effect/optical, and impulses per rotation depend on what you mean by "accurately".

Copped this at costco for $10 for lunch, but has come in very handy for transferring things that are sensitive to heat (I live in California, car heat up like crazy)

Mostly use it for keeping sunscreen, lotion, and food of course (also handy for keeping condoms and lube fresh)

Forgot pic, its expandable and so far it's worked very well

I also used it for transferring film for some vintage cameras I have, works great for films with humidity proof packaging

I'm also strongly considering getting an ankle kit for hiking/work

What lightweight absolute essentials would you reccomend?

One-Way

Robertson and Allen

JIS

Are you going to design your own preamp after you're done turning the copper?

>>1237082
I have no idea how to do that, can you recommend something to buy?

>>1237097
You're so hilariously out of your depth it's just tragic.

It'll be expensive, your results will be shit, Blackouts are already cheap enough second hand (Livewires even cheaper if you hate tone).

Why wind active pickups?

Shopvac and air filter

>>1236901
>air filter
I kinda already had that idea xD Any suggestions on which model or brand to get?

>Shopvac
Won't the greater majority of the DE slip passed the bag and end up in the filter? I mean, TWO FRIKIN POUNDS!! If it ends up in the filter... $35 a pop for a HEPA filter, that'll be expensive as fuck

once it's wet it stops being a problem. so maybe spray it a bit every now and then. blame it on summer humidity if asked.

>>1236484
The AC air is very low humidity so it will dry out the duct just by running the system.

>>1236484
How about a rug on a wire?

>>1236484
Ask hvac guy for duct plugs. They are the size of a shop vac hose. They are used to plug holes made to allow cleaning of forced air ducts.

Key hole cut duct.

Vacuum out.

Plug holes.

???

Profit.

Look into how fursuits are made. Be prepared to wade through some horror.

theres a lot of cool cottage industry viable manufacturing that goes into one

good luck op

Consider esp8266. Now u can have a wifi enabled trackball. 2 bux each.

>>1236471
>serial-to-ethernet adaptors
ethernet is a NETWORKING PROTOCOL
serial is a TRANSMISSION METHOD
Neither of these is what your trackball 'uses', perhaps you mean RS232 which is a PROTOCOL?

if you think you can connect ethernet to rs232 with a simple adapter then you are wrong.

You need an embedded system that can not only receive and decode state of the trackball in both hardware AND application(?) layers as well as host OR push messages onto the network while dealing with the overheads and bookkeeping.

of course it's possible, anything is possible.

>>1236566
I've done this with Ethernet to serial adapters. Just has to be able to handle raw data, and those are hard to find and they are expensive. More expensive than a trackball anyways.

OP how the fuck did that thing plug into a pc with a 10 pin? Pic of the plug?

>>1236435
Just add a shot of black!!!11!1!! XDXD

>>1236435
Super glue, baking soda, shot of black

Don't use it underwater. You'll die.

No, you'll fuck 99% of drills by putting 200kg of force onto it. Drill presses are designed to minimize the stress on the motor, and they are damn good at it.

>>1236350
Ok friend. How many wats should I be looking for? Cheapest ones start with 350w

>>1236352
No, its mechanical advantages that make drill presses work. But even with that you want at least a 3/4 horse power motor to do anything decent. That alone will run you $100 for a used one.

>in downtown Manhattan

cool. whereabouts? I own several properties in Central Park South, live in one about half the year when I'm not in the Hamptons or abroad, and rent the others to pay the bills.

We should do lunch sometime when I'm in the city.

If there is a gas line near the stove area, there will usually be a valve and pipe ready for a stove. Pull your stove out and look.

Electric stoves make clicking sounds. This is normal. It's the sound of relays opening and closing so your coils maintain the temperature you set them to.

Home Depot and other places will deliver for free within a certain distance of the store. This sometimes will include appliance removal also. A sales person at your local appliance store will be happy to let you know.

If you need a gas line installed, I would recommend hiring someone. NY probably has some strict codes around gas lines since large cities tend to fear fire.

>>1235965
Even if you're made of money no need to waste it, you'll probably want to replace the kitchen soon anyway. So why not just replace everything at once.

Then you can abandon the unergonomic placement of the oven under the hobs as well.

Lol. Easiest way would just be some buckets or cans filled with piss and a pulley that would tip the cans / buckets off the end of the truck. Don't know how easy it would be to keep them from falling over on their own, but that's for the engineers in China to figure out, right?

>help me /diy/ I want to squirt urine on passing motorists

Kek, but that's a lot of work. Just fill up a water pistol and drive by them with your pee pee poo poo fluid mix.

>>1235885
Alternatively, a leaf blower and a bucket of piss would also work. You'd just need to rig something up to cause the leaf blower to blow and then you could just have it sit in the piss bucket and spray on command

Good job, I like the knurling.

>>1235798
Pretty good lathe work for four months in. For something like that you should have put more work into the milled parts, those gashes in the clamp aren't acceptable. All you needed to do was flycut like .002-.003" off each side.

Did you thread the screws or use a die?

I mentioned small-engine repair because I thought that might be a good starting place.

A good place to start would be looking on YouTube for diy go kart builds. I would recommend t-mans garage or red beards garage(although rbg uses kits a lot it's still some good content) or just look around at some various channels. My personal favorite is bignickthegreat.

If you want to get into go kart making its a lot more mechanically inclined than computers, obviously. You're likely going to need to know or learn how to weld if you want a gokart worth its weight. On top of this, I recently salvaged a lil 196cc engine from a generator, although I wouldn't advise getting them from generators if you can manage, I had to buy a replacement crankshaft because the kind that was there for the generator is crappy for gokarts. i.e. tapered versus keyed. If not you can acquire a relatively cheap but reliable engine from harbor freight for about $120. It's 212cc engines and it's considered one of the best engines for diy gokarts. And for the most part it's basically plug and play. Good luck!

Pic related is the steering wheel for the kart I've been working on for the past few months.

pumps have 2 ratings, head and speed.
head is how much pressure it can impart to the fluid (measured in feet or meters, literally how high will it go), speed is how fast the fluid moves.
but its not just two numbers, its a whole curve.
at its absolute minimum head the flow speed will be the maximum, typically the same speed as the outer tip of the blades in the pump, you can work that out from rotation speed and diameter.
at the pumps absolute maximum head, where it literally cannot pump any more consider that the speed will be 0. between these two points there is an infinite range of head heights and each one has its own corresponding flow rate.

the pump manufacturer may show you a pump curve on a graph where you can trace the intersection of x and y to find the flow rate for your given head required, or they might just give you a maximum head and maximum flow rate, both are unrelated and don't go together but thats how they get you. sometimes it will give you one single point on the graph. if you ask them nicely they should give you the graph because a pump without a curve is no use to man nor beast.

everything you add, curves, bends, loop-de-loops, restrictions, valves etc all have an inherent resistance to flow, ideally you find what this is, convert it to head and add it to what you require when sourcing the pump. thats the tricky part. if its straight up or a single bend you might just kind of not worry about it just make sure you have a little wiggle room.

that skims the surface, if your feed is pressurised, fed from mains, dirty from a well, etc etc its more complicated

thanks for the info, but I wanted to do something simple. I have a set up with an electric water pump, I wanted to change that water pump with a manual pump, that way I wanted to simplify maintenance. The system has two tanks, the lower tank is of 150lt and the higher tank is 500lt (I know, it's not optimal it's an improvisation). Water has to go up for at least 6 to 8 meters, that's from a second floor to the roof of a third floor.

Any ideas? My doubt is if a manual water pump has enough force to pump water one floor up.

Sorry, english is not my native language.

Eight meters means a pressure of 0.8 bar or 80 kPa. This requires either a diaphragam pump or a semi-rotary pump. Both are expensive.
