Leatherman Wave

How long is the leatherman wave closed? Is it 8 inches (that's what the ruler is), or 4 inches? Thanks because this will decide whether I buy or not.

mechanical wave

I'm trying to build a tail of a fake animal, and the tail is kinda long (total length of about 3 feet), I have a 10 pound pull solenoid and I want the tail to kind of do a wave thing, like if you were do a wave with your arms ( not in a group, all by yourself where you hold your hands together, you know what I'm talking about). I know how to do the electronic part of it by sending pulses to the solenoid, but How would I convert that into a believable tail?

Instruct a wave.

Instructables can be much better. Powered by google wave. after i get my server set up with google wave i will try to help instructables by building extentions to help the whole thing work. Installing instructable found @ https://www.instructables.com/id/How-to-install-Google-Wave-to-your-server/ first instructables would need to install the wave extention to openfire and send me an email at james@jamesm.com.au when thats done for me to start working, making extentions. Installing instructable found @ https://www.instructables.com/id/How-to-install-Google-Wave-to-your-server/ robots made: Rossy, translater, spelly, spell checker, bloggy, alows waves to be on https://blog.instructables.com/ blog? please can still use wave, robots i will make: Sally, alows people to sell there projects using paypal, not made yet, hard, instructables robot, will be a hidden group that would include the robots above, hardest extentions i will make: JW, uploads video(mp4, flv, avi, ect), music(mp3, avi, wav, ect), images(jpeg, jpg, gif, ect), not yet, easy, swf view, alow swf files to be shown on instructables, not yet, easy Questions... will this disable instructables for a little lime? NO, to annoying. will we need to resumbit our instructables? NO that would take forever, robots job. what would instructables like this for? NO SLOW FLASH, faster to load, interactivity, save space Facts. Addsence will be getting instructables more $$ by more users. members can make group projects. members in an area can organize an event. eg maker-fair (please come to australia) members can add any files into waves. (some files may need a new extention just made for them) I will be updating this alot when I think of more so come back soon. Extentions found: Canvas -- bad when i saw this -- vectoreditor -- this has a little prob with text. like/dislike, html_gadget. Extentions i'm working on: JW player uploads and plays videos. (still needing some more development) Bot_protecter. simple editable div can not be recorded by bots eg. email addresses. (NOSPAM WAHOO) i will add all the xml files to a wave for me to create installers and add them stright into the instructable robot i am also working on. How will the gadgets be called without the xml file to add manualy? ok so if i can i will alow the instructable robot to change [canvas] [video] [like] [html] into the gadgets. the video first ask for a file and then embed that video with the jw player and lisenced if donations go towards that later in this project. and for the bot_protecter it will just pick up email address and add them into the safe gadget i made or get called by [safe]. theese can be shown as plain text by {canvas} that will show as [canvas]. if you want to see what some gadgets are goto http://jamesm.com.au/blog/ just remember that you neeed an account untill they alow guests to look at waves it is a smart way to embed the waves that i will make better when i can and this is not installedd on my server because i need to update the java. cheers and happy waven.

How to square wave ---> triangle wave?

Currently I have developed a flyback driver that is a semi-cross between a classic ZVS circuit and a 555 type driver, mainly just using a few comparators (one to create a triangle wave and 2 others to respond to the upper and lower peaks and drive MOSFETs. This allows me to create a modified sine wave with adjustable duty cycle.) This topology is even more powerful than the ZVS driver at 12V, as I got some INSANELY thick arcs!! However the MOSFETs get a little too warm, and I was forced to use sil pads to galvanically isolate the drain from the CPU heatsink. They seem to have really poor thermal characteristics as the heatsink stays cold while the transistors get uncomfortably hot within seconds!! To make this thing operate at the resonant frequency of the flyback, I think I will a feedback coil that would get "squared up" using a resistor and zener diode. I need to convert that signal into a triangle / sawtooth wave of fixed amplitude. A simple RC type circuit is not too suitable because as the frequency goes up or down, the amplitude of the voltage across the capacitor changes proportionally.What circuit will allow me to convert a square wave directly to a triangle wave of fixed amplitude????

Square wave inverter?

I am building an inverter that will use a square wave pulse to drive MOSFET's at 50-60Hz. I have read and heard a lot of stuff that running square wave into a transformer is not a good idea, what I want to know how bad is it? Also will adding capacitors as seen in my image be able to smooth the square wave a bit to help the problem? If so what capacitance should I use? (About 200A input) (The 12V square wave is coming from paralleled MOSFET's)

Will the Waves ever Die?

Think about it, the age is the Digital Dawn of the day, anologue Television is already being planned to me completely removed from the air waves in 2009 to make way for the "supposedly" DIGITAL SUPURIOUR HD crap. I don't watch that much TV to begin with so it doesn't bother me. But what about FM radio, is that ever going to die? Chances are probably not for a few years, seeing how the AM spectrum is still kicking around. How long can our traditional ways last? I'd be fairly sad to see FM leave the game. Really, we've had radio since the dawn of the technical age, from the 40's through the 80's (remember the days?). I just wanna see what anyone else has to say.

Half-Wave Rectifier Question?

Hello Everyone, Well, I built a half-wave rectifier using a diode and a resistor, but it doesn't seem to be working as I want. I'm thinking of adding a capacitor to help smooth out the wave, but my whole purpose was to produce a pulse of energy at 60Hz. Basically, to just chop off the lower half of the sine wave. For my diode I used a 1N5406 rated at 600V and 3 amps. The resistors are rated at 20 watts and the whole thing just plugs into the electric outlet. It seems to work ok, but when I take this rectified output and put it into a transformer to step it up to around 1000V thats when I have a problem. After its stepped up its supposed to charge a small capacitor from which the electricity (when built up) will jump across a small spark gap. The spark gap is adjusted correctly, but he capacitor doesn't seem to like to charge on this wave. Its rated 2KV so voltage isn't the problem. The problem is that it will fire once, but not repeat the cycle.  (The transformer shouldn't be the problem because I'm pulsing the dc) Any Ideas? Thanks

Power Sine Wave Circuit

Hi I am trying to build an economical circuit to power an AC electromagnet. The energy source has to be a battery, preferably less than 24v. The power draw of the electromagnet will be about 500W (the application requires a high-power alternating magnetic flux). I'm thinking of making a sine-wave generator and a simple transistor amplifier with high power transistors. Can anyone suggest circuits for this? My knowledge of electronics is not that great, but I'm quite enthusiastic about this and I believe I can give it a try. Any help will be appreciated. Thanks R

Sound wave heart beat detection

I love to graph things. Everything from outside temperature to server room temperature to the number of users on the network to my weight.I just read an article in Make magazine about DIY ECGs, and it got me thinking.. i want to graph more things about my body :)Would a microphone embedded in the bed be able to pick up the heart beats and calculate the BPM? This way I could graph development in resting heart rate over time. The microphone would pick up lots of noise from the person moving around etc.. but that doesn't mather. It only needs to get a few clean heart beats in order to calculate the bpm, right?What hardware and software would be suitable to create something like this?Any ideas?Yeah, of course there are other more traditional ways of measuring heart beat.. but I'm to lazy to do that.. I'd rather spend some time making a fully automagickal system.

Is there something wrong with my new Leatherman Wave? Answered

So I finally got a Leatherman Wave after finding a good price at a sports store for $55 (Wave+Croc+bit extension) but it isn't quite what I expected. I've never had a Leatherman before or a large multitool (Wave replaced a Gerber Dime), so maybe this is normal, but it is really stiff to fold at the pivot points. Some people say that it just needs to be opened and closed a lot to loosen it but I would like some advice. I haven't oiled it yet but I'm not sure what kind of oil to use. The tools and knives are ok, they don't require much force, but I am surprised by the folding action. Is the folding action supposed to go different ways? From the pictures I included, sometimes it goes to the right and sometimes to the left.

Simple comparator problems. (Outputting sine wave)

I just got a couple of LM2903N comparators off of an old board, and decided to do something with them. I have it running on +/- 5V, with the (-) input on 0V, and the voltage on the (+) input varied between +/- 5V on a 100K pot. If it is left like that, a sine wave of about 1.5V and 100Hz is generated when the (+) input is above 0V, and outputs 0V when the input is below 0V. With the output connected to +5V via a 33K resistor, the amplitude of the sine wave is significantly reduced, to about 0.1V Also, as the input voltage passes through 0V, the output will jump to 1.5V above or below 0V, and slowly return to 0V over about a second. The same is seen for both constant output voltage, and for the sine wave. (Tried this with both chips, and both give the same result) Thanks in advance for the help.
