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
>>927043 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.
>>927054 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
>>926965 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
Can we have this one? Tools that doesn't cost as much as your kidneys on the black market, even tho they are good for hobby/day to day usage.
For example a good Fluke Multimeter costs 200$+, while you can get a so-so one from China for 50$.
Pic related - my multimeter bought from ebay for 40$ Good, fast reaction time on diode check, "hold" button just holds the current value on the screen (kind of pointless imo). Doesn't have min-max which kind of suck. Test leads are rated for CAT III for 1000V (20A)/CAT IV 600V (20A) and look like... Comment too long. Click here to view the full text.
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,... Comment too long. Click here to view the full text.
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
>>926846 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?
Hello there. So i'm working on an autonomous hexapod and I need a gps, an ultrasound or a camera and some module to ensure communication between the hexapod and the laptop. I'm working using and arduino. I'd really appreciate your suggestions on the matter. The cost plays a major role but I won't go too cheap
>>926842 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.
so help me with these braces. I am retarded and dont own a drop saw, only a circular saw. also, I have chisels and a mitre guage and ruler things but I always get like a degree off and shit doesnt mate properly. so i am struggling to make timber braces. can I prevent the legs from sliding apart using steel cable? I'd rather not build some epic system of levers around this. its the legs of a loft bed frame. I am trying to keep it as minimalist as possible. if all else fails I will just disguise the bracing at the back with book shelves.
is there something more simple... Comment too long. Click here to view the full text.
>>926798 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.
>>926797 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?
>>926780 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... Comment too long. Click here to view the full text.
>>926806 I didn't want to be too specific and have people bag on me. I want to eventually make a bluetooth solar interior lighting system w/ app for entertainment lighting. I plan on using those new flat LED styling lighting. I'm keen on plastics because I want to be able to remold and remodel new designs if the first doesn't work.
I've never worked with fiberglass or any resins before, what tools would I need? I also plan on making my own cosplay gear this year so I'm building a small... Comment too long. Click here to view the full text.
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,... Comment too long. Click here to view the full text.
>>926757 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...
fwiw... Comment too long. Click here to view the full text.
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.
>>926747 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?
