A followup on my previous question, sort of... I have about 150 old semi used 1.5v AA batteries that don't have enough juice in them anymore to power anything significant. One can only have so many Joule thief powered LEDs, and it's a shame to dispose of them all. So the question is, what would YOU do (*Pointing at you!*) with those batteries? Thanks for any and all suggestions! P.S. Please provide an instructable if applicable :D

Hello everyone! I am trying to build an arduino RF remote control to clone my remote control for my wireless sockets. I bought this RF module from ebay http://www.ebay.com/itm/New-433Mhz-RF-transmitter-module-and-receiver-link-kit-for-Arduino-ARM-MCU-WL-/140847542952?pt=LH_DefaultDomain_0&hash;=item20cb2af2a8 At first I thought it was damaged because I wasn't getting any signal from the reciever. After many tries I touched the reciever with the remote and suddenly I got the codes (I want to recieve the codes, save them and then re-transmit them with the arduino). The same goes with the transmitter - the only way it works is when I hold it against my wireless socket. It means that the codes work but the signal is way too weak. I tried hooking it up to different power sources- Arduino 5V, Arduino 3V, 12V 1000mA Adapter, and the original battery of the remote that states 12V 23A. I tried making an antenna but nothing really works.. please help! thank you..

So I have a 95 chevy C-1500 5.7 V8, Been having some progressively worse problems with it running rough and hesitating when accelerating. I will be re-timing it soon but that is a separate issue for the moment, When I tested the ignition system I noticed the spark tester was glowing orange/red instead of blue. (I can't even get my timing light to fire) It was due for new plugs and wires so I replaced both. The Ignition coil is less then a year old and I just finished replacing the Rotor and distributor cap. Still have an orange spark. I really need to fix this before I can time it, Any Ideas?

Hi there, I recently borrowed a ds converter. I'm having trouble with the IR signal strength. The remote won't work until i'm in the range of 2 to 3 feet from the DS converter box. I'm thinking, it must be weak IR signal or brightness. Can you please suggest me ways to fix it. Thanks in advance, Rosh

I made a signal boosting rig out of cardboard and aluminum for my router for my PS3 to access it ('cause I can't move the router in my current situation). So anyways it started out boosting a 17% average signal strength to a strong 50%. But now a couple of months later, it's maxing out at 23% and it's been happening for a couple of weeks now. Also, my ps3 absolutely refuses to work with anything below 25%. So what changed? I haven't moved the rig since I set it up and none of the furniture has moved either. The only factor I can think of is the changing of the seasons. Anything else that could of caused this?

What are the best circumstances or best time to get the laser treatment for eye sight surgery? I know i should talk to an eye surgeon for this, but before going to him may be its a good idea to talk to people here who have a prior experience and have themselves undergone the procedure. Also it would be great if someone can suggest me some reasonable costs for laser eye treatment. thanks.

As the title says, I'm looking for information about the material nylon. I want to know anything anyone can tell me. I am mostly wanting to know it's melting temperature, and how they prevent air pockets from forming inside nylon products during manufacturing. I would also like to know any additional information you are willing to share, such as it's uses. How rigid is it? What are it's weaknesses? How hard is it? Just anything at all, really. I thank you for any help you may offer and I hope you have a wonderful day.

I just got finished building a stirling engine using plans from instructables author: thecheatscalc published dec 17 2007. The stirling engine is a heat difference engine. Is it possible to create a magnetic difference engine using stirling theory? I was thinking instead of hot and cold north and south or strong and weak..?

When I tried to start my car the ignition just clicked a few times, then finally started. It seemed like the battery was weak. I spoke to a mechanic who said probably one battery cell was bad and advised that I replace the battery. I did that and now have a brand new battery. I didn't fix the problem. Does anyone have advice?

Hi! i've an iPod 4th generation a while ago my screen cracked so i took it to the repair shop to get it fixed. when it was done, everything else was okay, except the wifi... it is able to detect networks, just that it's really weak, like it can only detect network when it's just beside the router. previously i was able to use the ipod wireless in my room, but now it can't connect even detect wifi in my room (the router is in living room), as it was too weak. in other words, the wifi became weak after i changed my screen? what's wrong with my ipod? any suggestions please? THANK YOU!!

Alot of K'NEX guns use "sights" to improve accuracy. Thing is, they never work because the gun is usually weak and not accurate. are they mostly for decoration or do they have a purpose?

Here is the review for the Z35 K'nex Assault Rifle by Oblivitus.What to expect:Innovation: 9/10 Very innovative loading system. It also has a new trigger system. Strength: 9/10 Very strong. The one weak part is the handle, the connection to the body is weak.Range: 8/10 The range is good for a mag gun, about 40-45 feet.Looks: 9/10 One of the better looking guns on this site. The one thing that could make it look better is using less blue rods.Parts: 9/10 Uses quite a few parts, But it's worth it. Handle: 7/10 The handle is good but the connection is weak.Stock: 9/10 very sturdy Barrel: 10/10 Innovative slide mech. Trigger is very innovative as well. Magazine: 9/10 New and doesn't use cut parts.Extras. Bipod:8/10 not the best but it holds up the gun.At the end: I would give the gun 9/10.Here is the link to the gun. https://www.instructables.com/id/Z35-Knex-Assault-Rifle/Thanks for reading.Killer~SafeCracker

Behringer B212D PA system main driver works for 10 to 20 minutes before stops working. but the compression driver continues to work. If I power off the amp for a second and switch back again, the main driver works for minute or so. After couple of hours if I switch on the amp again, same process repeates. I am able to hear the main driver working for 10-30 minutes only, every time I use. after that, just the compression drivers shrill sound continues.The amp is also not that Hot at that time. It is an unit from 2009.Is it a thermal issue? Or any capacitor weak? Or any other weak component?Thanks a lot in advance.
Question by bnsahu | last reply
You know how they have those solar powered air fans you hang in your car window so the car won't get too hot in the summer? Well I spent $35 and bought one, and it's a piece of junk. The fan won't even turn. I'm not sure if the motor is too weak or the solar panel is too weak. Panel is quite small, like 1 inch by 5 inches. So I'm looking for a cheap one to build myself, perhaps using the case from the old one. The problem is, how much surface area in solar panels do I use? Maybe I'll just hook the old one to another car battery, then hook a solar trickle charger to the battery to recharge it. Hmmmm... Anyone want to try and post an instructable for this idea?

Well, here's my only idea for the LED competition, seeing as I'm a complete noob at LEDs. LED illuminated Jello. It will be weak compared the other LED Instructables, so, I guess I'm asking for you're opinion on the idea. There could be a chance for the random prize. UPDATE prototype made, see picture.

K'NEX guns are often weak but the publisher makes them look strong by sharpening the rods it fires. Banana inventor's pistol shot 20-30 feet but he said it could go through cardboard with a sharpened rod. And Gorkem's sniper rifle only was powerful because of a sharpened rod.
