I have a Samsung Young 2 (G130H) that i plan have permanently connected to a power supply. It's manly connected to a car so it powers on when the car is on and powers off when the car is off.

However in the long run this will not be good for the original Li-ION battery, so i am thinking in replace it for an alternative.

I only need that the phone runs at least 2 minutes after the power goes off so a capacitor should do the trick.

However i am not sure what kind capacitor should i use to replace the 3.7V Li-ion (4.81Wh): charge voltage 4.2v

Can someone help?

Thank you

>> No.1216327

BTW i've mooded the phone, so now he can power on when the power is connected and turns down 1 min after the power is unconnected.

The thing here is to give the phone the ability to safely shutdown using other power source.

Hello /diy/. I'll be moving out soon and I want to get rid of my old broken bed. I'm planning to build a plataform bed. The thing is I don't want to use nails or glue. I have at my disposal files, handsaw, hacksaw etc. I plan on using 4 boards and using the wood square grid thing that holds the matress from my old bed. I want to know what kind of cut should I do on the edges of the board to fit them like the pic so they don't slide or move.

I have a similar question: if I go with two-factor auth using my phone, and my phone breaks, how the hell do I get back into my account? If it can be done, then doesn't that defeat the whole purpose of two-factor? Do they send a physical letter to my residence, which is not known by many online accounts anyway?

Everyone says 2-factor is the best if you don't have a physical auth like a dongle or iris scan, but what if the phone breaks?

Retro Radio Mod

Im trying to make a custom radio using a cathedral radio case that I have (pictured is the exact model). I plan on using an android phone, cheap mp3 player or raspberry pi as the guts.

My problem is that I want to use one of the existing knobs (or build a knob I guess) to switch between 5 or so playlists (and a police scanner feed) but I dont know anything about using knobs as controls. Can anyone help me with this?

The tuning knob is probably connected to a big mechanical capacitor bank inside the case. Sight unseen, the best bet may be to clear all that out and replace it with a 6-position rotary switch such as Pic related, with a matching shaft type and length.
Of the three devices, the rasPi will have better I/O capability for the extra controls. You can either poll them in a little app program that watches the GPIOs and sends commands to mpd or kills and restarts mplayer or whatever, or if you feel bold you could try your hand at device tree overlays and use gpio_keys and triggerhappy to run shell commands.

Spend the money on some tools.
Cheap shit will work for a few projects. Figure out what you want, what tools you use the most. Then upgrade to something better.

My jigsaw and palm sander are both harbor-freight specials. Cheap as fuck. They've worked for a couple projects now.
Had a HFT circ saw. It got me through a few projects. Upgraded to a cordless system.

Tools pay for themselves pretty quick.

Any reason you can't wall-mount the TV?

I'm looking to make a centrifuge using this 3D printed rotor https://thingiverse-rerender-new.s3.amazonaws.com/renders/9c/5b/4b/aa/81/Dremelfuge_Chuck_Edition_V4_preview_featured.jpg or similar, but that spins a little faster. G-forces on the sample are proportional to rpm^2, so a little extra speed would really help.

Question is, what tool goes faster? I have a 30k rpm Black and Decker rotary tool, basically a dremel, but I'm seeing air die grinders and pencil grinders that go 60k rpm, like this https://www.intlairtool.com/chicago-pneumatic-cp9104q-pencil-grinder-1-8-collet-60-000-rpm-05-hp/. This would give 4 times the g-forces as a standard dremel.

But I know nothing about air tools. Would the pencil grinder be able to spin a sample of this size(8cm diameter plastic rotor with a few mL of water in the tubes)? Would the spindle bearing shit itself at the slightest imbalance? Can I run an air tool at way less than full speed if I want? Is the air from such a tool directed forwards? If so, it would probably knock the rotor out of true.

Is there a class of tools that I'm not thinking about that would be better(faster) than a dremel for this task?

I work in a lab and our plastic centrifuge rotors max out at 15k but average about 13k depending on the machine. I'd use a solid rotor and not that spoke looking one. The more weight you have then the more your going to notice wobble. We try to get them roughly the same volumes and usually if it's above 10 ml then it's not going above 2k rpm. A lot of the 13k rpm stuff are just 1.5 ml eppendorf tubes. We do have 500 ml tubes what use a stainless steel rotor. I don't want to be around that shit if it breaks. I think the plastic will break at the spindle, the long part that connects to the drive motor, with what youre going to be doing unless it's balanced very well.

>> No.1216205

I'll add, all of our plastic rotors have metal spindles.

>> No.1216215

Yep, definitely not trying to spin anything bigger than a 1.5 mL eppie (I'll use the high speed kind, I know they are good around 100kG). Keeping a small plastic rotor and operating inside a thick casing makes me not so worried about failure causing injury.

You think the break point is where the arms attach to the spindle? Guess I could redesign to make a less sharp cornered attachment, and maybe angle the arms forward a bit

Hi, all.

So I got these metal dice as a gift. I'm pretty sure they are these ones here (though it was a gift, so I'm not positive):

I don't care for the green color that they use for the numbers, so I was going to remove it and make them blue. But there are a few things that I wanted to know first.

First, should I worry about removing the other paint first or just paint over it? I'm pretty sure that I should remove the paint, but if any of you have just painted over the other paint and it worked, then that seems the most simple.

If I should remove the paint, how should I go about that without damaging the surface of the dice? If they are the same dice in the above link, then it says that they have a nickel finish on them. I googled removing paint from metal, but I didn't see any metal that looked the same as the dice, so I didn't want to apply any chemicals to the metal and wind up removing the outer coat.

Next, what kind of paint would be best to use? If you can't see in the picture, the numbers are engraved (perhaps there's a more specific word for what I mean, but I'm pretty sure that's it), so I shouldn't have to worry about the paint coming off when rolling the dice. I saw some paint for painting the d&d miniatures (which is something I'd like to get into making out of wood and painting myself, but that is for a later date), would that work for this?

What kind of brush should I use?
Should I cover the parts I'm not going to paint in masking tape, and if so, how do I accurately cut out the areas that I'm going to paint?

What other issues might I run into?

And lastly, did I miss any info that might help you out?

Thanks everybody.

I'm guessing what you would do is hit the whole thing with a dremel wire brush, dip the entire thing in whatever appropriate paint (enamel is first thing that comes to mind), and then hit it with a wire brush again painstakingly outside the numbers. hand work that will make them feel made with love and care.

First, try some organic solvents that won't hurt the metal finish. Paint thinner, mineral spirits, acetone, etc. and try to wipe the numbers off with a cloth. If a solvent works, dunk the dice in there and leave them overnight. The numbers should just wipe clean.

When they're all clean and dry, replace the color with some nice model paint or some other relatively thick paint you can dispense with a needle tip bottle into the numbers.

>> No.1216216

Sounds like solid advice. I didn't know about the needle tipped bottles. Thanks.

>> No.1216223

Thin your paint, brush the die with it, wipe off the excess with your finger. If you screw up, wipe clean and do it again.

You're not wrong. I was an apprentice at a machine shop for two german immigrants. I had a precision machining certificate from the local CC, they had me work from 4:30am mopping the shop until 5:30pm driving back and forth to the heat treat shop like I was some bitch. They also paid me $9.50/hr during my apprenticeship, then offered me $8/hr FT after I completed the apprenticeship. I was basically a slave, who was always wrong, could never do anything right, and worked at beck and call for free.

I quit just after two years, I couldn't do it anymore. I live in America, being run ragged by two Germans, while I live far below poverty. Been far below poverty ever since, but I'm no ones bitch.

Hey, just bought a house at tax foreclosure. The matriarch died, and the crackhead kids ran it into the ground astoundingly quickly. They piled up trash, performed no maintenance whatsoever and drank hundreds of bottles of liquor which they proudly displayed. I also found a crudely made sketch of plans for a still, which was never built. The house was built in 1949, but the owner cared for it quite well, and aside from one small leak, the outside of the house is in decent shape.
I already filled one 40yrd dumpster with trash from just the garage and two sheds, and I think I will need two more for the house. I am holding my daydreaming at bay until I remove all the crack pipes, dead mice, carpet and trash from the house.
I have found quite a few nice things in the house, a cabinet of Snoopy/Peanuts collectibles, mostly made in Japan, porcelain dolls, gold/platinum edged China, silver dollars, HAWAII silver certificates, a C3 T-top Stingray with a 350, six or seven decent pieces of furniture and lots of other stuff under the trash.
The favorite thing I have found so far is an old Gramophone in fair condition. I want to restore the gramophone and furniture, but was not really sure how to do so, can I simply sand and restain it, perhaps using some woodputty to fix some gouges on the feet?

A barrier free tile shower with grab bars, new furnace (ruined by water coming in the vent), new condenser, new electrical panel and wiring and some tuck pointing on the chimney.

In my area they have a year to pay back taxes. I wouldn’t improve shit. Developers often front the money in exchange for a good deal.

They didn't pay for three years. I officially have the deed.

Hey /diy/, I had this rubber tip stylus pen but I lost it a while ago. I'd like to make one.

It seems to be a simple rubber on the tip of the pen, but I don't know the exact type of rubber which is used. (It is not eraser rubber, I've tested)

So any ideas for doing this?

Even in the 3rd world they sell cheap chink phone stuff like cases and chargers. Hell ive even been to Mexico and they sell everything there. So unless you live in some african village i bet you can buy one of those in some market.

You're looking for something called capacitive rubber. Sponge may also work. It should be the size of your last stylus tip.

Hey /diy/, I'm building a Raspberry Pi robot (my first project on RPi) and I need your advice. I want it to continuously measure the distance between the robot and any object ahead of it so it can know when and where to turn. Are those components good enough or do I need anything extra for it to work?

Check the voltages on the sensor board and the pi.

Can't tell if joke, or saying he should order whole spools instead.

>> No.1216025


Probably what you're looking for.

>> No.1216029

The site doesn't allow to order just one resistor. The minimum number of resistors you can get is 10, due to the fact that they are incredibly cheap.

Try first with the ultrasonic. If you see your sensor outputs as "noisey" or "jittery" try to implement a low pass filter in software
