What's the best material to make hands that will setup relatively quickly and easily and be lightweight?

We're building a Traveling Korean Memorial w/19 soldier figures walking through a rice paddy and 3 soldier figures making a campfire.  We don't have the funds to purchase 22 mannequins so I'd like to make the hands which will be connected to rebar that will be the form of the figures.  This Memorial will be setup outdoor as it displays across the country, so it needs to be able to withstand the elements. Thank you in advance.

Make serial connected batteries easy to replace Answered

I am working on a project that requires two serially connected 9V batteries to power.  For when the batteries will need to be replaced, is there an easy way for a user to replace them without having to disengage wires and then solder new ones?  Is there a way to "rework" the typical battery caps used on 9V batteries?  Using an 18V battery is not an option because of the size of the container the battery is being placed in. I was thinking to use two battery caps, one to connect the positive and negative posts to make the two batteries (9V) serially connected, and then "rework" the other cap to connect the remaining posts on each of the batteries to provide power to the unit I'm making. Is there a way to do this ? Is it feasible?

High SWR on CB radio? Answered

I've had a long, hard journey to try and get my Cobra CB to transmit properly. Let me explain. My radio never has been able to transmit properly, and my friends with their CBs (they have the same kind as me, and their SWRs are fine) can't even hear what I am saying if we are parked right next to each other. This is very surprising, because I have a 4 foot long Firestik antenna.  So I borrowed my friend's SWR meter and measured my SWR. I have well over 3 in all channels, which is WAY in the red. I immediately printed out Firestik's high SWR troubleshooting tips, and did everything it told me to do. I tried tuning the antenna as usual, I tried checking all the grounds and connections, and even changing antenna positions. Nothing helps at all. I was still in the red, and my friends could not hear me. I thought that maybe my antenna or coaxial cable was at fault, so I borrowed my friend's working magnetic-mount antenna to try it out. With the different antenna, my SWR was worse. Finally, I decided to just get a new radio, because maybe mine had a fried resistor or something. So i took my CB back to walmart, and successfully exchanged it for a brand new radio (without receipt or original box, for that matter). And just my luck, the new radio STILL has a super high SWR, in the red, the same place as before. I am all out of ideas. I have searched the many CB and off-roader forums on the all-knowing google, and nothing helps. Does anyone have ANY ideas on what I can do?

Arduino pro micro RFID and servo

I've successfully implemented Door Unlock system described in this tutorial. At first I used Arduino Uno and RFID RC522 Reader and MG90S Micro servo. When I used Arduino Uno with Arduino Pro Micro for arduino ATmega32U4 5V/16MHz, the RFID reader stops wirking after pluging the servo. Since Arduino Pro Micro have only 5v output, I used resistors to downgrade 5v to 3v in order to poser the RFID reader. I used same output 'vcc' to select 5v for the servo and 3v converted to the reader. The problem is that each component woks perfectly independent each other, however, when I place them together they stop working.

Where to find a small form factor 12v Battery?

I am looking to build an LED light that can be powered directly by a 12v source or use an internal battery. I expect that the fixture form factor will be about 4" in length by 2" to 2.5" in width and no more than 3/4" in depth. Internally, it needs to fit two LED units (each draws 0.1-0.2amps and only one would be on at a time) that are 1"x1"x5/8" each, the inside component of a single pole double throw waterproof switch and the remaining space for batteries. I would like to fit the maximum amount of available capacity as possible in as small a space as possible. I am looking for battery suggestions - small form factor, 12v, preferably available via a regular source (i.e. don't have to be special ordered from China), low self-discharge rate, ability to withstand temperature extremes (specifically 120F-140F degree heat). I'll consider wiring up batteries in parallel and serial to get the charge depth and the proper voltage. Any thoughts? I looked at A23 12v batteries and 2CR-1/3N 6v batteries (wire in serial) but I'd like to find something with more available capacity. Also, I'd prefer a non-toxic battery, but will consider lithium, and the ability to be recharged would be a big bonus. I'm guessing there's nothing out there that would give me enough life to be happy, but I thought I'd ask. Thanks!

Control led strip light with arduino from 12v?

Hello, I would like to control my 12 volt strip light (not RGB) with an arduino and also use a potentiometer to be able to adjust the brightness manually.   However I am afraid to fry my arduino board with 12v directly as it will fry it and I also want to be able to use higher voltages in the future but for the time being only 12v volt will do. I don't really know what to use to control high voltages and current so as to be able to control it.  My choices are relays but most are from 220v to 12v and can only be on and off so very difficult to control brightness.   Another choice would be to use my potentiometer but again I don't know how to control it and especially about the value such as 10k for example.   Then there is the use of transistor such as MPN and NPN which I don't remember how to use. It has been at least 4 years since I was in electronics and now want to get back in so as to create awesome things but I need to be sure that I am safe and for other people as well. Thanks again for you help.

My random bullpup model

So Dr. Richy posted his CAR which drew a little inspiration from this weapon that I posted on Red's wall in hopes he just might be able to turn it into a firing weapon. However, as I suspected, that's just not an easy task and I didn't expect it to happen. So I'm gonna just throw this out there and show anyone that didn't see it. It's made to be convincing, it could probably be turned into a real firearm. It's a bullpup designed to take 5.56 NATO rounds. I designed it to be somewhat ergonomic and compact. It has the front grip from...I don't even know how long that I used on my UMP. It's pretty simple, reasonably comfortable, and lets you quickly attach any front grip or bipod you can come up with. The muzzle was made from a new concept for a rounded barrel that could be used as a real K'nex barrel. This can also take a very cruddy and simple silencer attachment (which is actually just my Master Sword handle that I never wanted to disassemble). Then I added a basic rail on top that allows it to take airsoft or real rail accessories. It's not perfect, but you can get the accessories to grip into the grooves. I added a fake charging handle that is located in a decent, but not optimal position. This flows into a cheek rest of sorts that's rather close to the back of the gun so it can accommodate the charging handle pin. Your head is kinda cramped against your shoulder, but your face itself is comfortable aiming. And the front sight is detachable if you were to add a rail sight. I'm thinking I'll probably make a new one tonight for fun. It'll be shorter to be similar in size to a PDR. However, I might (not a definite) give it exchangeable fake barrels based on this one that allows it to lock in with a single pin. Secondly, I'm going to change the front to include an integrated folding forehandle that will also be comfortable to hold folded. Or so I hope. I'm also going to move the charging handle forward and make the roof one and the same with the rail to slim it down ever so slightly. This will also move the cheek rest forward to a more accurate position like on Dr. Richy's. Finally, I hope to add some nifty features but I'm not sure at all on these. One would be a bolt lock which probably wouldn't be too hard. It'd basically be like the charging handle is a firing pin and the bolt release would be a trigger, just mounted differently on the gun. And then the harder one would be to make a magazine release near the handle like on a PDR instead of the current one I use that makes you have to "strip" the magazine. On a real gun, this would be a great feature for making reloads a lot faster.

How to store hydrogen at low pressure?

What is the most practical and cost efficient way to make a 10m3 gas bag for the storage of hydrogen? I am planning to store pure Hydrogen (made from water electrolysis) in an outdoor area, a bit like the way biodigestor gas is stored in low cost, small scale installations. My concern is the high effusing nature of the gas through membrane material. My first thought was to use reinforced PVC like that used for truck tarpaulins but I can't find any info on effusing rates verses other materials. Ideally the gas would be able to remain in the bag for a maximum 2-3 weeks until needed. This is an experiment on the practical applications of locally produced hydrogen, so I hope to be able to follow up any advice by constructing the gas bag and reporting back with the project progress. Any thoughts and advice would be gratefully received!

Arduino Coder Needed - Will Pay

Hello,      I am in serious need of some help with code for a Arduino Uno project! This would not be for free of course. Just let me know what would be fair. So if your in the mood to help a dummy out, drop me a line! Here's some background on the project The project is a prop for a Halloween haunted house/escape room. The idea is for 4 RFID readers to detect 4 objects (Maybe optical sensors are better here for triggering the audio?not sure). Once all 4 objects are placed on top of each reader, the adafruit Wave Shield produces a telephone ring sound effect (I will be providing the sound .wav files to the adafruit SD card). I would also need to have a the ability to push a button to stop the ringing and skip to the next audio file on the SD card of the Adafruit wave shield. Hope that all made sense :). Below are links to all the pieces of hardware I am using: 1. Arduino Uno - I think you know what this is 2. 4 x RC522 RFID Readers  - 3. Adafruit Wave Shield - 4. Maybe Photoresistors for triggering instead -

I roughed out a design (reversed engineered from various pictures) a tennis ball rebounder for a co-worker but it doesn’t look like he has the interest to build it anymore.  It’s a nice piece of equipment for anyone that likes to play tennis since you can set it up in driveway or basement.  Here are a couple of examples: Video 1 Video 2 I would like to do an instructables collaboration on the project with someone that would find this useful.  I would tweak the design (overall size, hardware, etc.) with your inputs.  Your responsibilities: Buy the materials which I’m estimating at less than $100.  Note that purchased versions cost up to $500. Build it - requires only a saw and drill Take a few pictures of the build and final product. Help with the documentation if needed  In the end, it is your rebounder to enjoy.  See my past instrucables for examples of my work/documentation.
