2 MB,
I picked up this broken psp that was listed as not charging. At first i wired a tp4056 circuit to the battery terminals but it would not charge. then i read sony batteries have a chip inside so i wired an 18650 cell to the board. i have a charger on the way but it won't power on so is it worth doing anything with? or what should i do next

buy a new battery? even if the old one still have some juice left you will end up needing new one.
If it still doesn't charge, check up the charging circuit on board - starting from the connector and up until the battery lead.
the led on the tp4056 board went blue so indicated the psp battery had full charge but it read almost 0v on meter and the same when I opened it up and measured the lithium cells directly. Is there any way to test it out before i spend more money on it? I soldered the 18650 to two pins directly without the board in the picture but it would not power on either.
so you saing wiring the PSP directly to a power supply doesent works either?
I'm not sure but shit might have resistance measurements like the apple crap has that stops them charging from "non-genuine" chargers...
if that's not the case, try measuring values from the battery to the power button.
In the end, the shitty button might went bad from the previous nigger's greasy fingers

Hi guys

With geology in the shifter I need to be coming up with a Plan B. Where should I start with welding if I want to get into a shipyard?

My CC offers as evening courses
Oxy acetalene
EN certified manual metal arc

Just need to catch the recruiters eye with a course

Doing what in a shipyard? I've worked on board, and if it's just doing basic work in a drydock arc welding is common, but oxyacetalene is used for bigger jobs and fabricating stuff.

I should note I wasn't involved with it personally, that's just what I've gathered from the crew and engineers doing stuff.
As an apprentice boilermaker, I'll tell you what u done to get here.

When i was still im high school, I worked for free for periods of time, it's called work experience. This allows the employer to assess you and somewhat train you. Do what they say and what they tell you to do.

I'm guessing you're out of school now so your best bet would be to go to TAFE (Trade school or equivalent) and get the certificates in welding, be a sponge and learn everything your instructor teaches you.
I'm a ex welder now I'm a welding inspector / welding engineer go to your local collage get qualified and coded and then you will be sorted depending were yyour from get into refinery and power station work

Best bet is to find an old analog scope. I bought three just in case someone was an asshole and sold me a broken one. IIRC I paid $16, $40 and $60 for each of them and they all work.

Hey /diy/ :)
Looking for a practical method of cleaning these seashells - pic related. I want the one on the right to look like the one on the left - I assume its jadeness / discolouration is a result of some sort of chemical reaction with the salinity of the water - obviously its a bit scratched up, so it's not going to look EXACTLY like the one on the left, but I just want something to bring out the colour and disolve excess scrub.
I have tried using a file already and found it just disintegrates the shell completely. Looking for something a bit more efficient,...

Woops, the picture was rotated for some reason, probably got to due with the import on my phone. Sorry about that. I want the one on the left to look like the one on the right. Thanks folks

before peroxide, soak in citric acid and baking soda in alternate sessions to get rid of anything that is caked on the surface, then peroxide, that will give you a good surface, but if it is rough by nature, there is no way you can make it like right without heavy sanding and polishing
I figured out when I was filing it down that the colouring is just on the outermost layer of shell, that is, too serious a file/sand/grind/scour will probably just remove the colour clean off. I really like the idea of polishing though, what material should I use?

what size and what kind of distance are we talking about? i would think a raspberry pi is more suited in your case
The robot is small you can fit it in a box of 10X10X10 cm
for the distance I would say about 70 to 80 meters.
What kind of communication? Telemetry? Video? Commands? What interface are you using to connect to Arduino and laptop currently? Also what terrain? You could achieve everything with a simple 2.4GHz WIFI or RF link.

Traditionally you'd use rods, joined in the middle of the 'X'.

As you've observed, flexible cables are not much use in compression.

If it absolutely has to be cables, then a wooden brace across the back would make the member a full box, and then the only movement you'd have to worry about is where the legs stay parallel and move away from square. Cables can help now, because whichever direction this happens in, one of them will be in tension.
the other option is to make the shape trapezoidal, so the angle fights compression, and use cables to keep them from spreading.

I have this kind of kitchen faucet i am trying to teach young kids not to turn it on full blast when doing dishes and use less water Any idea ....

Get a dishwasher.

Any solution that relies on everybody in the entire world doing something is not a good solution, particularly if that thing is annoying or inconvenient.

If you want to save water and energy washing dishes, then get a dishwasher. It can wash dishes better than you can, because it filters and recirculates the water instead of pouring it down the drain.
Maybe a switch that will actuate an electric fence unit if lifted too high?
Copper plate what mains positive hooked up screwed to wall behind faucet so lifting it too high completes the circuit to earth?
Bear trap screwed to wall in same position?

Possibilities seem endless, OP. Where's the hard bit?

Hey /diy/
I have a few questions and I'd appreciate some help on these:

I recently bought some InstaMorph and another brand of polymorph Plastic along with a Dremel rotary tool.
End goal is shaping a rough prototype for my idea.

What are the best materials/tools for prototyping in the early stages?
I want to eventually just print off of 3d printers but for now I need to get the first design to size.

I was thinking of shaping out wood to the pieces I need then molding the plastic but that seems like so much work.

Buddy it's all depends on what you're making.
If you're making a housing for a device that's as big as a TV or a microwave, you can go with wood, since its secure long lasting relatively light.
If you're making something the size of a cell phone wood would be bulky. maybe use aluminium sheets if you know how to shape them. these are somewhat sturdier and look more solid but are a bitch to put together if you cant weld.
If your set on plastics, use a polyester resin and fiberglass and...

Hi /diy/. /mu/ /gg/ here.
I tried asking multiple people about this issue, and all of them had different answers:
>1. I need to know about soldering for guitar modifications. /mu/ was not much help on this. I want to replace the neck pickup of my red strat with a Seymour Duncan Hot Rail. However, I also have heard that it may be smart to put it in the blonde strat instead and use the Gold Lace in the red strat neck posistion instead. I have no idea how to solder, and I know that doing it myself would save me money. I've googled some instructions,...

you'll need a soldering iron, soldier, flux, and a safe place to do it minimum..

practice soldiering wires of similar size together before you try it on the guitar...

once you can make a nice shiny looking soldier joint reliably then try swapping the expensive pickup out...

also the increased tension pulled your bridge up... it will increase the action towards the higher frets on the neck... probably not fantastic for your neck since it changes the angle the strings pull at slightly...

+1 to all of this. Congrats on having a go. Put it in whatever guitar YOU want to.

For later, ignore 99.9% of advice about guitar related tone chasing. Just practice more. Can't say that enough.

One day you will remove the duncan pup and either put the stock one or a lowish output pup in.
+2 this. Also, if you didn't want the bridge to be up just tighten the screws holding the springs in the back.

Hey guys, hope you can give me some advice.

I got this old Dremel tool from my deceased grandad. So I don't have a manual or anything. I use it for a lot of stuff and love it, but lately it's started to give off a high pitched whine using it. It sounds like it just needs to be lubricated.

Do any of you know where i can squirt some of the lube into? I don't want to ruin this thing if i can avoid it.

Don't oil it. Use thick grease like lithium bearing grease. You can get it from bike stores for 1$. That said, get it on the armatures or brushes and you're fucked. There's probably a bearing kit or it could be failed electrical. What kind of whine?
Just right down in there? Just put a couple drops in there and run it?

So would I have to take the whole thing apart?

Thread thickness is dependent on the needle, not the machine. So get a needle that can handle thicker thread.
