35 mm film belt

i work at a movie theater, and we always have old pieces of the film strips. lately i've been considering making some of this old film strip into a belt, by laying it on top of the other pieces and weaving thread into the little holes on the edges. but i've been thinking about how i'd attach a belt buckle, or anything to clip it together for that matter. anyone have any ideas how i could do this?

Used 35 mm cameras

As I was looking in a thrift shop recently, I realised that all the ones I had been to had these old 35mm film cameras for a really cheap price.  The burning question I had was what could be done with these cameras and the parts in them?  Are there sites where this is addressed?  There must be a ton of things to be made with them and they will become re-purposed materiel.  How about a contest? Anyone?

5 mm led's 8 LUMENS PER WATT!?!?!? [answered] Answered

Well i was thinking, 5mm LED's take about 1/10 of a watt, correct?  and from this calculator found out Cree 5mm led's are .806 lumen's. i assume they are 1 tenth of a watt. well, my calculator states they are 8 lumen's per watt (if i could run them at a watt.)  i figure they are 1/10 of a watt because because this 500 led light makes takes about 50W as in the video and led's give less than a lumen of light. so far, it seems leds just last long and emit blueish light. is incandescent light better? with 20 lumens per watt from halogen?

trying to feed video into a 3.55 mm port on car dvd

My car dvd player has twoscreens. One DVD player feeds the other screen when you select either one to act as an A/V in. It accepts the video feed sent from one player to the next via a 3.55 male to male cable. I had this idea that if the one screen receives a video signal from the other player than I could bypass the DVD sending the signal and send a video signal from another device (my iphone 4) using the same method. I bought a Iphone 4 to rca audio and video cable to run the video feed out of the phone. THEN in theory I thought that an RCA to 3.55 male converter would allow me to run the video line out of the iphone into the DVD players screen. I would have to sacrfice one audio line (left or right, didn't matter) to plug the video into it BUT I thought in theory this wouldn't matter as audio/ video RCA seems to send video feed just fine. NOW, I have it all in place but it doesn't work. Any ideas how I can make this 3.55 female line in on the DVD screen get a video signal from an iphone?  Thanks for any advice here.

3.5 mm 4 pole splitter question (for use with ipod touch)

Hi, I'm attempting to put together something that is conceptually simple -- making a splitter for the 3.5 mm 4 pole audio jack so that one end supports a mic and the other a pair of headphones. I'm doing this because I want to hook up a better quality mic than found in the store-bought iphone headsets. However, after putting it all together, I just can't get it to work with my ipod. I've followed these pinouts (where 1 is the tip and 4 is the base): 4-pole jack 1. Left Audio 2. Right Audio 3. Ground 4. Microphone 3-pole jack 1. Left Audio 2. Right Audio 3. Ground Ive verified that all the connections are good using a multimeter. But when it comes down to actually recording with my ipod, I can't get the line in to work. Has anyone does anything like this before? Any ideas what might be going wrong? Is is it possible that measurements on the 4 pole jack isn't standardized and that the one I have doesn't actually fit the ipod correctly? Perhaps I'm completely wrong about how to connect the wires. So just in case, this is what I did: Line-in: Pinout (P/O) 1 and P/O 2 ---> P/O 4 (on 4-pole) P/O 3 --> P/O 3 on 4-pole (on 4-pole) Line-out: P/O 1 --> P/O 1 (on 4-pole) P/O 2 --> P/O 2 (on 4-pole) P/O 3 --> P/O 3 (on 4-pole) So yep, that's it. Any help is much appreciated : )

Sub-mm precision ultrasonic or inductive distance sensor for use with Raspberry Pi?

Hi there, I am trying to keep my hardware/ coding skills alive and spruce up my bicycle wheel truing stand. I need to figure out the required hardware + software for the following: I want to build a non-contact distance measurement sensor system and get the output "into" my computer for display in a graphical user interface. I know I could omit the latter step with going directly onto a mini-LCD screen, but trying to use this a learn-another-programming-language learning experience (I've coded Matlab galore, pondering Python for this project). General system components: Sensor - [something - RasPi or Arduino I guess] - laptop (running debian) - GUI displaying continuous sensor reading Sensor: I've web-searched the hell out of this, but not finding anything quite answering my questions. I want to continuously measure the distance from the sensor to a bicycle wheel rim braking surface. Material is aluminium, shiny, though not smooth. Biggest problem with the web-search is being swamped by proximity sensor results (on/off) rather than a distance proportional output signal and much lower resolution projects. I rule out IR or optical sensing, now stuck between ultrasonic and inductive sensing, though tending to the latter for a faster response/adjustment to change time. Sensor criteria (other than reasonable $$): - total sensing range: ca.5mm - sensing accuracy 10 to 100micron/ 0.01 to 0.1mm - don't ask if that's needed, a bit of overkill, I know, but a bit of OCD doesn't do any harm, eh? - fast-ish sampling rate (so that when I turn the wheel, the number on the screen updates nice and fast, guess >25Hz is sufficient). [Something - RasPi or Arduino]: I know that I could omit the laptop GUI part (mini-LCD, LED array, etc), but keen to learn/ practice a little Python with this project, so I guess I am tending to the RasPi, but I am open minded. All I want is the analogue sensor out to end up as a digital reading "inside" my computer to be passed to my GUI as a reading. Essentially a mini A2D converter. Not fussed whether the output is in actual distance units or in arbitrary units/ current units (I guess the sensors put out a proportional current signal?). GUI: Depending on the above, how do I best get the signal "into" a Python program? A moderate fast sample rate >25Hz should suffice. Any help with this would be greatly appreciated!

Polycarbonate panel thickness for secure windows? Answered

I need to glaze 16 small panes (430 x 275 mm) in very strong, cast aluminium window frames (8 per frame, either side of the door). Is 3 mm frosted polycarbonate going to be impact resistant enough to keep people out? The building these windows are part of is in a fairly remote place, so security is a concern but for cost and aesthetic reasons we don't want to glaze with glass and install a metal security screen. The current ugly solution is boarding them up and securing with screws but this doesn't allow us light inside. Cost is a consideration since I've been given permission by the company that owns the land to reglaze them and if I provide the labour they will supply the materials. 16 off 3 mm sheets, £3.85 each = £61.60 16 off 4 mm sheets, £5.14 each = £82.24 16 off 6 mm sheets, £7.70 each = £123.20 I've found lots of sites shouting "yeah polycarb is badass! It's unbreakable!" but not one that gives an idea for thinner sheets. Am I wasting money by going for thicker sheets? Or if someone's trying to get in might a 3 mm sheet be breakable?
