USB to AA converter?

Basically, I want to power a small AA device from a usb port, preferably terminating in something that will fit snugly into the two-AA receptacle. I searched the archives, but couldn't find an equivalent project. Any assistance would be appreciated. Thanks.

Competition Shooting Timer made with Arduino

I have only begun to use Arduino in the last few months, and my skill set is still somewhat lacking.  I can easily build the circuit that I need, however programing is still difficult at this point.  Especially trying to write my own program from scratch. I am looking for help to make a Competitive Shooting Timer for IDPA competitions(international defensive pistol association).  In my head it should use a piezo speaker as a microphone on a digital input, have a couple LED's for currently working and ready status, an LCD screen that shows the time lapsed since the first shot occurred to the hundredths of a second, and a push-button to stop the timer. Any help would be greatly appreciated!!

What switch to use for LED Light project

I have  seen a few build on here recently with installing LED lights on stairs.  I am liking that idea and overall have an idea of what I will do with the lights, but I can't seem to find the switch I want to use. I would like to set this up with 2 lasers or beams.  The idea is that one would be at the top of the stair and the other at the bottom.  They would be in  the wall so you can't really see them.  I only have easy access to one side of my stairwell so I am hoping the set up is something like a beam going to a reflector.  Once a beam is broken, the lights come on and remain on for a short period of time (30 seconds or so) and then they turn off.   The problem I am having is I either find thing like garage door beams that are big and hard to hide and require access to both side of the wall, or beams that only travel a foot and a half at the most.  The stairs are the standard three feet or so.

Where to find power knob for Lakewood model 101 box fan

I have a Lakewood model 101 AB box fan that I had in storage for several years and when I took it out to use it, it is missing the rear back power/speed selection knob. It is 1" diam. and needs a small slot in order for it to attach to the post sticking out from the motor. I have spent quite a bit of time searching for this or an appropriate universal knob and I recently learned Lakewood went out of business several years ago. Any ideas on where I can find this elusive part so that I can use my fan? Thank you very much for your help.

Listening with Stethoscopes through Glass Windows?

I'm writing a zombie apocalypse fiction story and in one scene, one of the militia has to eavesdrop on a survivor gathering through a padded window using a stethoscope modified to fit onto a walkie-talkie earpiece microphone (the type that's along the same wire as the earpiece). The stethoscope would be placed against the glass window. The eavesdropped survivor leader is using a loud announcement voice with no acoustic assistance, in the middle of, say, a 20m x 10m x 3m lobby. The sound would (theoretically) reverberate through the glass window and into the stethoscope, which would focus all that sound down into the mic, which is transmitted by the connected walkie-talkie to our actual listener that hears it several kilometers away through the second, receiving radio. Notwithstanding the padded window (since the character finds a hole) and assuming the transmitted signal isn't distorted at all, how bad would the audio fidelity be for the listener? Would you still be able to understand audible speech? Would listening with stethoscopes through glass windows even work?

Current in IC chip

Hello, It's a bit stupid to ask (I think), but essential to me. From all schematic I readed over intructables I never saw anything or anybody that cared for that. If a IC have a maximum and minimum current to respect ie: 6mA to 10mA, do we even care? Do I need to limit the current somehow? As I said, every schematic I readed never added any resistor or talked about anything relate to limiting the current on the VCC for the integrated circuit.

LED Lightbar DIY

Hi folks, I hope this topic is in the right place. I was going to try my hand at building my own LED light bar like the one in the picture below. It will be around 40" long with 2 rows LEDs and running off a 12v car battery. What W LEDs would you recommend? Also materials, what would you use for the housing, clear front etc? I was looking at 10w SMD Chips but I'm not sure if they are super bright but then again there are going to be a lot of them in the bar. They have a operating Voltage of 9-12v, if I have so many of them will i need some sort of amplifier half way down the rows? Any help with this project would be greatly appreciated, Thanks in advance. Chris.

I tried to use the Instructables app to write an instructable. I loved it, writing an instructable as you go and clicking the camera button was great, made it really easy. BUT when I got done and went to publish it I clicked publish and it said it was uploading photos.  I laid my phone down, Moto G running kitkat 4.4.2 on the counter, when I came back it said network error unable to upload.  So I clicked done and tried to upload again, this time it immediately said network error couldn't upload.  So I completely closed the app tried again, same.  Restarted Phone, same. All the while having a strong WIFI signal.   So as last resort, I cleared app cache, well, this deleted my instructable........ Those should really be stored in a separate file that is not erased by a cache clear. So what was wrong? I had a great internet signal, there was NO network problems.

Loudspeaker design advice needed. Mini-array Viston FR10 drivers

Hi all, I'm about to get started on my first set of loudspeaker cabinets. Since quite some time I have 8 Visaton FR10 drivers lying on a shelf and I want to use those. After some research on diy loudspeaker cabinets I came up with the design in the attached drawing. Before I start building a pair of these, I'd like to have some advice on the design. I'd like to keep the costs as low as reasonably possible :). Questions I have and some design considerations: - Are the tubes correctly dimensioned? I used the "vented box calculator" over here to get the dimensions for a cabinet with one driver. I doubled the area of the tube and placed two of them in the cabinet. - I plan to clad the inner walls and the backside of the drivers' frame with convoluted foam. Do I need to fill the inner volume with some kind of polyester wool as well? - I want to use the speakers with my "Serious Amp". Will that work? - I planning to build the speakers without a filter. Is that wise? - The four drivers in each cabinet are in pairs series // parallel, to get a joint impedance of 8 Ohm. - As I understand it from the various forums / websites, it's best to place the drivers in a vertical line. However, the cabinet becomes too tall to fit in my tiny livingroom. I just don't have the floorspace to place them. Am I going to regret that decision? Your advice is appreciated! Y.

Why did Text/Photos Disappear from my Instructable? | HOW TO FIX!

If I had a dollar for every time I accidentally clicked on another place on the screen while working on an Instructable, resulting in loss of data... Even if you click the save button many times, if you suddenly quit, the editor won't remember what you did. I've seen SO MANY comments saying that the editor didn't save what they wrote right before uploading, so I decided to share what I do to help stop this... Most members will see this forum topic only when it's too late, but at least they might remember this for future I'bles... 1. Open a "Preview" version of the Instructable in a new tab. If your computer crashes, you might be able to restore previous tabs, and your computer should remember what was written in the preview. Then you can copy and paste everything where it needs to be... 2. Send yourself an email of each step. Just copy and words of each step and paste them on one draft email... 3. Take screenshots. At least you'll be able to see what you wrote... Hope this helps! Please leave ideas of what else you can do in the comments
