That is not normal, why do you buy wobbly chair when everybody else except you doesn't have this problem?

The problem is you, stop wobbling the chair

those batteries will provide far more current than your adapter, either replace the batteries/charging circuit or get a much bigger adapter

this are the internal bat's
1.2v each connected in series.. so im guessing the motor eats 3.6v. the charging adaptor is 5v dc 300mah.

a friend of mine told me this things need a lot of mp's to work..so i tried connecting it directly to the 3v and then to the 5v line. first with the rotation swtich on then directly to the motor. but it never turned.

what can i be doing worng? what shoukld i try? can i have burned the motor? the screwdriver was working before dissembled

damn, sorry for explaining bad, i missed a line and it was that i tried using a pc power supply as a power source for this unit as they give a lot of amp's, thats why i said i tested the 3 and 5v lines..no luck though, and thakns for the fast reply!

They're gold plated. Nicer circuit boards use a process called ENIG to plate exposed copper to improve corrosion resistance.

In cheap, mass-produced electronics, sometimes bare pads are used as contacts for membrane switches, which is what you have here.

Note that the amount of gold on the entire board is best measured in micrograms, so it's not exactly worth much.

>ENIG
PO here, ima repo guy and ive saved about 200 of these boards, and i come into contact with out 30-50 a day. Is it worth processing if in bulk?

>>1206892
Older cellphones have a larger amount of gold there is ways of buying scrap board and recovery with acid

Some more pertinent info.

What is the hot water used for?

Electric boilers are a massive waste of electricity.

What kind of heat? Forced air? Radiant?

Prop structure held by pole
Cut post
Remove post
Clean concrete somewhat
Remove small amount of dirt from hole
Pour coffee can's worth of mixed quickCrete
Smooth while wet
Place post on concrete
Attach new post to old structure

Oops, also let the concrete dry first

Support the weight elsewhere, cut about a half inch off above the concrete, and hammer in a half inch thick welding shim under the pole.
Easy.

How do get rid of these sick ads at the bottom of the page that have no place on a blue board?

>>1204670
depending on the topology it can limit your operating range. that is to say, you'll only have zvs under certain conditions so you may end up having to design for full switching losses anyway. also it's more harder.

If you can't get an apprenticeship you're effed. You could try moving to an area in need of electricians, but it sounds like you're a poorfag either unable or unwilling to move away unless someone else flips the bill - and paid relocation isn't really a thing anymore since it's cheaper to hire within and train them over the internet whereas in the 90's and prior it was sometimes cheaper to hire and relocate than to hire within and send them away for training.

You're retarded. You should be paying him more.

Your fan not running has nothing to do with a condensation line. If your fan motor was bad he probably should have replaced it same day, unless it was after 5 or something, but sometimes A/Cs have odd fans you have to order.

You don't have the know-how to find out if the fan is powered or not, and that's the important part. You can't do it. If it's getting power but not spinning, you may have a bad motor or a bad capacitor. If you don't have power to the fan, you may have a bad relay, transformer, breaker, etc.

Window units? Don't they only last like 7 years and only cost like $150? No point in dropping another $120 on two busted ACs. Just get new ones. Or, save up your pennies and invest in a house size AC of some type. Central, split unit, whatever. Something that will last more than a few seasons. If you rent, well, just kill yourself and get it over with.

Bait surely? Anyway I'll bite.

>Highly illegal.

>You will be in deep,deep trouble if you attempt this - you cant go around violating airspace without expecting a whole shitstorm of problems, and most likely long terms of imprisonment.

>>1202530
It's legit not bait, I have built prototyles and flown them to a different city and back and never lost a drone except for when one crashed nearby but I found it and got my phone and salvaged the parts back.

I seriously want to do this, even flying it to France and back is a good starting point, I am from the UK.

>>1202531
If you violate another country's airspace you are committing a number of serious offences, probably even terror related.

if it falls on a populated area in another country you will be in deep deep shit.

Security services take this stuff very very seriously, don't do it anon.

The first place to start is real machinist forums. Practical Machinist is educational, then hit home shop machinist forums.

>I don't mind getting an import knee mill or bench lathe and converting (or building from scratch) new ones that ride on air bearings and then probably CNC.

You have too much to learn for one thread and you fucking need to study MUCH more. Fuck bench lathes and tiny import junk. They exist to piss off owners.

The best way to go is get smart about a variety of industrial machines so you know what to look for. Everyone hears about Bridgeport but Excello, Wells-Index, Tree and others are excellent.

Forget conversions until you know a LOT more. That means doing a lot of fucking reading, following links to yet more reading, and learning how to move machines without paying a rigger (which besides saving you mad cash can let you move machines from places no forklift can reach.) Google "moving a Bridgeport" to see the principles of moving many different machines.

You also need to abandon /diy/ for machine tool questions. You'll be glad you did, so do it.

Pic is how I've moved several milling machines, grinders and lathes. The wide outriggers are a touch I've never seen elsewhere so I spread the word because my method is exceptionally stable, safe and cheap. Orange channels are bolted to machine base by dropping all thread through the base and holes drilled in the channel. Green outriggers are then attached to the orange channel. You hold the allthread (use quality Grade 5 or better allthread) with visegrips and tighten the top nut to raise the machine off the floor. When all four corners are snug I winch the machine. onto a trailer and tie it down securely. It can't tip and is easy to handle. When doing a mill I usually cut two four foot sections of four inch angle and bolt underneath the mill so I can also fit a pallet jack beneath it for final positioning.

>>1201997
Thanks alot, I've been lurking around there for a couple years. Just poking DIY to see what's going on here.

I on;y want an import to mess around with, Don't want to mess up a decent bridgeport and have to shell out cash for parts, Imports can just be scrapped for parts however.

Not sure if I'll get more of a response here or the QTDDTOT but meh. I am in need of some machinists tools. Need some taps, a level, square, straight edge, and a dial gauge. Which of these things do I have to spend on and which can I buy cheap? Any recommendations for brands or specific tools? Where's the best place to buy?

My thumb and index finger.

A shot load of water pipe.

You're not going to have much of a selection. The Home Depot and Lowes and Ace Hardware all have pretty much the same options as far as ladders and hand trucks go. And as far as tools go, you'll have to buy each one individually. One tip you need to keep in mind when it comes to tools is ou get what you pay for. If it's something you want to make a career out of, spend the extra few bucks. If it's just to do a quick job, then buy whatever you want, but if you want to start a shop or something, you want quality. Trust me.

>>1208694

Thanks, I guess I'll continue with the Home Depot selection. So far I landed on this handtruck http://www.homedepot.com/p/Cosco-Shifter-300-lb-2-In-1-Convertible-Hand-Truck-and-Cart-12222PBG1E/205430398

I think this one is medium. Decent price and very very good reviews.

>>1208695
Yeah those are really popular right now. I've never experienced any issues with them, but there are so many pieces and things that could go wrong, that I'm weary of them. If they have anything else go for the solid ones that are just one piece. I guess it depends on what you're moving tho. If it's boxes n shit, that one you showed would be ok. If it's like a bucket of copper parts or something, you'd want the solid one. Just my two cents.

Yes you can make a press using a jack and wood, but be aware that if it fails it can seriously injure you.

You can borrow pullers for free (refundable deposit) at places like auto zone, but if you do this sort of work you should eventually buy your own.

Also, you will probably need snap ring tools and special tools to align things; quite often you can rig up or do without special tools, but be aware that you might hit a road block and have to carry the pile of parts to a pro.

Get a manual. If you don't have a really good manual you will probably screw up.

Good luck. I rebuilt similar but simpler transmissions years ago. It's fun if you know what you are doing (or can figure it out) and you have adequate tools. If you lack either it's an exercise in frustration.

I suppose everybody here already knows this, but if part 206 is a pressed in bushing there is a cool way to remove it. Pack it nearly full of grease, and place a rod in it that is a good fit. Then hit the rod with a large hammer, and the grease will partly spurt out around the rod, but will also push the bushing out a bit. Repeat as needed.

>>1207944
I've got all the hand tools I think I'd need and have professional experience as a mechanic (not automotive but there's a lot of overlap). I'm looking for a shop manual now.

Heat?

>>1207398
Should I blow a fan on it?

>>1207396
Perhaps you didn't let what's under it dry well enough? Dunno. Bumping for interest, though. I was thinking about using that stuff next time i finished a project.
