I have a kobo aura Ereader, and lately I've been wanting to improve its battery life by a gigantic amount and/or making it never needing to be charged (like a solar panel or handcrank). My ereader has great battery life, but I'd like to see just how far I can go.
But let's just look at the battery life idea. I have two options I can think of so far: 1) connect some external power cells to my ereaders carrying case and just use my usb charge cable to connect battery to ereader. 2)replace the internal battery with something much larger. somehow.

Hello /diy/ I'm looking to put together a balloons of a word like Banksy's throw up in NY. I can't locate any material other than mylar to make em, and would prefer something that isn't shiny. What do?
I just programmed a led blink program into a PIC16F628A. What do I need to know before I design and build a development board to house it? I'm not a complete noob as I've made dozens of boards before but it's my first time with a PIC, basically.

I'm getting an amazon shopping list flushed out with a few things I want, but I'm not sure what i should do about the last item, paracord.
I want something sturdy, that can hold my body weight, is flexible, and won't make noise when attached to something like chain does and more importantly is small. So I came to the conclusion that paracord is what i'm looking for.
I only really need about 25 feet of it for everything I want, but I figure ill buy 10$ worth whether its 50 or 100 feet as I'm sure at some point in the future I will have... Comment too long. Click here to view the full text.
>>933564 A single paracord not actually rated for human safety. You will shock load it to 1500 pounds easily and break it and fall to your death. Get climbing rope if you're climbing. It's a commodity and prices down as far as it can go.
>>933591 Don't worry, like I said, not using it for life and death, what I want it for is something sturdier than twine that's able to hold weight.
the two things I want it for are this
1) hold a rotary tool by the I beam in the basement so I i get the least amount of twist in the flex cable. and 2) using it to hold onto and exercise with my own body weight. think of how a gymnast rings, but instead of suspending my whole body, I use them as close to the ground as I can in the push up position.

>>933532 > They have a positive and negative terminal Resistors are not polarity sensitive anon.
>>933531 Could be. Could also be a fuel cell. It appears to have some sort of nipple on it along the edge which could either be a gas vent or an inlet/outlet for electrolyte. Is there another nipple behind your thumb or on the opposite edge? Does it feel heavy like a battery or hollow? Does it sound solid when you flick it with your finger?

Take as close and clear a photo of it as you can (like, prop your phone up with something so hand shake doesn't rape it) crop out the QR, blow it up some in paint then save as a monochrome bitmap (so you are left with black and white, hopefully clean enough to read). Dump the resultant image into a QR reader >your phone >phone
Hi I'm looking for any advice or ideas on how to finish this window. In other rooms they're flush with the wall so I just have a plastic trim to cover the wall/ window boundary however due to the tiles this one is set back from the wall and the frame partially hidden by the adjacent wall on the left. Please help me finish the bathroom?
>>933601 Since when do RCA connectors have plastic rings with a metal tip? It's clearly a male center pin DC plug (think nokia charger), no doubt this plugged into a power brick to run the light.
OP, pretty unlikely you'll find a brick to suit it, you'll need check the lamp for power ratings (a sticker on the underside of the base that tells you the power consumption of the unit) find a matching wall wart, splice it in and you're done. You're gunna need to open the lamp to work out whether that... Comment too long. Click here to view the full text.
Or something similar. I've actually seen IKEA lamps that used RCA connectors for their 12V connection from wall wart to lamp cord. Bad idea. Imagine digging around in that rats nest of cables behind the audio equipment and connecting your phono input to a 12Vac source.

Is this a skill that one can achieve with different levels of difficulties? I ask sincerely because im this close to purchasing a sewing machine because I dont know how clothes are made and it would be hard as fuck.
>>933452 There's lots of different skill in lock picking. You'll have to get into a lock picking community soon to play with 'challenge locks' because the ones you can buy from the store or amazon are pretty shit unless you start shelling out like $50+ each, and you can only pick a lock a couple times before you know how, and you'll just nail it every time, which won't actually raise your skill for new locks anymore.
>>933454 Ill check it out but I only work, have a bunch of money, and just need a hobby. Ill probably get a sewing machine this weekend at the second hand store then chuck it into the dumpster a few days later. Same will happen with my lock pick kit comes in next week
im currently a welding student at my local community college and ive gotten pretty decent at hot forging steels. i have stretched earlobes and i want to make myself a set of rings in 3/4 inch diameter. essentially my question is if hot forging 316l surgical stainless steel will reduce its resistance to corrosion(i dont want my lobes to get infected). basically i want to take a 3/4 inch piece of round stock, shape it into a circle(pic related), anneal it, polish it, sterilize it, and stick it in my ear. is this a bad idea or can it be done?
Smithing things that are that small is difficult and a high skill task, but certainly doable. Especially if doing a simple shape like it sounds you are.
The steel surface that's exposed to air will oxidise while heated, and the iron oxide layer will not be corrosion resistant. You'll want to polish that back to bare stainless when you are done forging. That should be the only corrosion issue.
>>933439 My blacksmith friend has just what you are describing. To make something truly corrosion resistant you need to clean it with acid (but can't recall what). And if you are working with ordinary steel in the same room as stainless there will be dust which again will rust the stainless. Take it out for cleaning and use tools dedicated for stainless when you clean it.
>>933425 I'm certain you could. But is the board firmware coded to utilise a socket which was not installed at the factory? Do you know the values of all those missing components? Do you know what type of chip is supposed to be on the pad labelled U560?
>>933398 No issues. In fact it is good that the rats in the sewers get nutrition as much as possible. After all, without pushing as much edible as possible in the swage system the rats and other disgusting vermin might even die! Thank Bob that isn't going to happen anytime soon.
I've seen enough failed drain lines and drainage issues in houses to know you should put as little as possible down your kitchen drain. Its a garbage disposal, but over the years it WILL slowly get clogged and could be avoided if you didn't use it as a trash can.
If its wet organic material like pulp and you're doing it regularly, make a compost bucket and use it on your flowers or garden.
If you're in an apartment and give no fucks, then yeah use it as a receptacle for anything that will fit and drain.
