Recently I started learning how to repair videogame consoles, and even though I already repaired a ps1, it was just by luck, I'm very inexperienced, does anyone know any page where I can learn?

repair of consoles is basic electrical engineering 101, ohms law and shit. If you see a cyllinder with 100 uF 25V written on the side and can't identify what part it is, then you should get a book on electrical stuff.

/ohm/ has a cluster fuck of resources, but I recommend Getting Started in Electronics by Forest Mims. Train your imagination and draw some electrical problems as you go through the book and try to build/understand what the circuits in the back are doing. I've gone through 1/2 the book so far and it's very good at understanding pretty much every electronic component used today and the past. It may take like a month or two to rly get what's going on, but you'll be able to understand shit. but it's basic electronics.

if you wanna skip all that shit:
an MIT hacker(Andrew 'Bunnie' Huang) has a book called Hacking the Xbox. I'd say if you want deep knowledge i'd get an xbox off craigslist and go through the book. its free to google

some chapters he has is:
Building a USB Adapter
Replacing a Broken Power Supply
etc.

Arduino containment thread

The last thread died some time ago, so let's start another one.
I don't have the OP pasta, so someone else can post it.

This thread is for Arduinos and arduino related ICs (ESP32, Blue pill etc)

Hello /diy/ I am in the middle of replacing the screen on my honor 8 phone and it seems as though the white cable connecting the mother board to the daughter board is broken. I cannot plug it back in to where it was placed. It looks like when I have unplugged it the connection point was ripped off too.
I was wondering if it would be okay to solder this cable to the board but I am scared I'll fuck it up beyond repair. Any advise you fellas can give me? Pic related is the cable in question. Will provide more pictures if that helps

That looks like an antenna cable, anon. If you have a micro iron, you *might* be able to solder the center conductor and shield to the appropriate pads to get by. If you can get the old connector out of he cable you might be able to reuse it, or, you can probably find the appropriate connector on an old laptop wifi card. Again, you need to solder it either with a micro iron, or hot air. Here's an important question: did the copper pads on the board get lifted when the connector ripped off? If so, you're fucked, new phone time.
>>
>>1625757
That's an antenna cable. It's a simple coaxial cable, so you only need to worry about two contacts. As >>1628980 said though, pray to Kek that your solder pads are still there.

should be fine to solder it right back onto there

I've got this year-old gas leaf blower which was working until 2 weeks ago but won't start anymore. I can't get to the spark plug because everything is cased in plastic, which is held in place with deep T-star bits and I don't have a long, narrow T-star screwdriver.
Anyway my question is, how long should I wait before trying to choke/start it again? The manual says to not pull the crank too many times, but doesn't explain why that is...

Hey guys,

I purchased a chandelier, and I tried setting it up, but only 3 of the 8 bulbs seems to be working. The bulbs are fine, I checked them with another lamp. On the pic you can see how I tried connecting the wires together. One thing I don't understand: as you can see on the picture I will post right after this one, there is a black cable coming out of lower part of the lamp, but at the upper part it looks like the previous ownder didn't need to connect that. What could be the problem? Thanks!

thanks, I think it could be pre-WW2, and it's in Hungary. I'm not sure about the black wire tho, since it's connected to some stuff inside, as this pic shows...
>>
>>1632187
> 3 of 8 are working
so the fault might no be the black wire. Follow the wires of the 3 working bulbs and check how they are wired compared to the 5 that aren't.

Can you post a full picture of the lower part
>>
>>1632218
basically the brown at the top should be line, blue should be neutral

assume each lamp (bulb) needs a line and a neutral.

two wires from each lamp should be in the bottom part (one blue one black?) (one line one neutral)

so you should have 9 lines connected together and 9 neutral connected together.

if the brown wire at the top goes to only 3 wires and the black wire at the top goes to 5 wires and the blue wire goes to 8 wires then you need to connect the black wire to line to light up the 5 lamps.

if you want 5 instead of 3 swap brown and black at the top. if you want all 8 connect them together.

if its the blue at the top that only goes to 3 wires then connect black to blue or swap as required.
>>

I rearranged the wires and now it's working, thanks. it's a bit embarassing that it was so easy to fix but I'm a bit afraid of repairing stuff connected to electricity...

It's the insert for a Delta brand tub spout.
The O ring is the seal inside the spout.
Get a Delta spout
Remove the new insert from the new spout
Swap the new O ring to the insert in your pic
Screw the new spout on and you're good to go.

Teflon tape or pipe dope is not needed for the spout to insert threads.

I'm invested into the milwaukee m18 and m12 tool line but I am afraid 10 years down the line, they would discontinue or change the battery interface that my tools don't work, does anyone else have the same concern?

Precisely, everyone is dumping money into making lithium better, nobody wants to gamble a billion dollars and 10 years of time on an unknown and potentially unsuccessful battery chemistry.
Lithium is the sure shot right now.

>an unknown and potentially unsuccessful battery chemistry
And since lithium is the most energy-dense element for making batteries, a substantial improvement would actually involve something other than a battery, like an air fuel cell or a gigantic improvement in capacitors.
>>
>>1632289
There's still a lot of progress to be made with lithium cells, were nowhere near the theoretical limits of the chemistry

I finished assembling a greenhouse and this part (actually two of them in total) were left over. They were packaged together with door handles but they were not part of the door handle/lock system. The big round end is a strong magnet. What are these for? I would use them as a door stopper (when the door is open) but I have no idea what they were actually intended for. Any ideas?

Makes sense if it's a swing door, bolt it to the wall or roof and the magnet end holds the door.
Not much use for a slide door unless its auto close.
There is also often some kind of trickery in a greenhouse to do with windows opening when it's too hot for example, but a magnet alone? Not much use I doubt you would come near its curie point just in a greenhouse!

>Makes sense if it's a swing door
Yeah, there are swing doors, one on each end of the greenhouse.

I live in an old ranch style house in California. The roof has a double pitch; a conventional slope near the peak that flattens out to a shallow pitch over the porches (which cover about 60% of the perimeter of the house, front and back). I've just been told that I might need to get my roof replaced. The previous roof was install before I bought the place and it seems they didn't do a good job because it leaks in one of the valleys. Picture related. I've had the place looked at by 3 different local outfits and they all say they valleys need to be redone at the very least. There are two valleys. We get a lot of sun, some high winds and some rain here. We get a light dusting of snow once a decade or so.

So, what kind of ass raping am I in for? They say quotes are in the mail. The total roofing area is about 1,400 square feet of standard 3 tab asphalt shingle and rolled roofing. How much could I save if I rented a container and stripped the roof myself? Would that even be worth my time?

easiest/cheapest way to install lock on bedroom door?
7 replies and 2 images omitted. Click here to view.

>>1631937
Most bedroom doors have knobs with "privacy" locks on them that can be opened fromt he outside with a "key" that is really a small screwdriver. Is this what you seek? What do you have now? non-locking doorknob? no knob? no door? Do you want a keyed lock? Replace bedroom doorknob with exterior locking knob. At this point your lock is far stronger than your bedroom door, which is probably hollow. If you want good security from druggie housemates, replace door with steel-sheathed exterior door. Replace the frame with the one that came with the door. It should have steel reinforcement too. This is a lot of work from a first time DIYer. Put quality deadbolt on door, and suddenly you are the least desireable person to steal from, as long as the window isn't too easy to bash in.

Something like this.

Should be cheap because locks like this are quite shit really.

Should be easy because really, all you need to do is screw the parts onto the door/frame. Might want to pre drill for the screws if you want to be really clever.

Hello /diy/.

I want to settle a communication using RF. Thing is that the transmitters will have to be movable and the receiver must be static. It will have to work + 100 meters. The transmitter will have to be like a market RFID sticker.

The receiver can have current input, wifi internet, sim paid access.
What electronics do you recommend.

The information from the receiver should be send to the server.

I own a fairly early Starrett 3M and whilst very similar I don't think OPs is by that maker.

That said all the early mikes are hard to tell apart if they don't have a visible maker's mark, all being modelled after B&S's design with minor variations.

It looks like a real early Browne and Sharpe.
They had that frame shape, and they had the screw holding in the anvil.

A pre-WW2 metric B&S must be very rare. Is the seller asking silly money?

I've got a gorgeous Starrett 127M set in complete and perfect working condition. Picked it up for a steal on eBay. Box needs a bit of tlc but it's such a great conversation piece and totally usable.
>>
>>1629853
I'm gonna come back and say that it is most likely a Brown and Sharpe. After looking at a few other examples, almost all of the older B&S micrometers I have seen have two patents on the back just like that one. Also note that the patents only use their date, not a patent number. That means it is a very early patent. I can't read the entire date to track it down but they appear to have 190X in the date. Picture related is a B&S patent from 1902.
