windows server 2k?

Okay as in my previous "adventures" with my server, i installed ubuntu 32-bit.g Great it works! but when i started the server again, it asks me to choose between Ubuntu( wich i will call U from now on), U(recovery version), memory tests, and... what? Win2K. first of all, why would it not load exept after i installed U? second of all, I'm stuck at the login screen. So if anyone knows how to recover a password or change a password without opening you session please tell me And if anyone has a link to Win2K's user's manual, please tell me that too. thanks again to everyone :)

Hoax? A task not only for high-schoolers...

       Well, exept for being quite a fun thing to watch, it also should work as a great Physics problem for someone like me (or a bit younger)-studying all sorts of Mechanics and Newton's Laws to work on... The task is to estimate the acceleration the motorcycle should have to do it, and whether it's significantly larger than the one stated in some technical data (there is the motorcycle model somewhere in the video's name).        If you have a go on it and are a) school-aged and b) not sure you are right, PM me. If you simply want to share your results and/or opinion, write here (but try not to put any solution-I mean formulas). In case the video doesn't work

I need some help an an ignitor box (loook in details)?

Me and my brother had built an ignition box (1st project) that can be used for rockets and fireworks we sucsessfully had gotten the box to launch. Then we had the idea to add 6 volt lights and an organized switch setup. But we came across the issue of the circut bypassing our negative lead for our 6 light by the positive lead from the 5 light going to switch 1 so therefore basicly switch 7 isnt needed exept to light-up light 6. So now we need help on how to prevent this issue from happening. please help and thanx- Jarred

Need help removing weight off a motor

Hey guys i'm currently trying to make a very simple robot (2 motors, a battery and a switch) and everything is fine exept for the fact that the motors i'm using are from a PS2 controller, so they are vibrating motors. I can't seem to figure out how to remove the weights (half metal circles) that make tthem vibrate when rotating and that's going to be a problem, since i want my motor to have wheels, not vibrators hah... So if any of you have advice on how to do it i'd be glad to hear it. PS: i joined an image of the motors so you can see the half circles i'm talking about.

I have "compaq vocalyst keyboard" without PS/2 nor midi. Is there any way to make an USB adaptator to use it ? Answered

So, I own an old Compaq Vocalyst keyboard (very similar to that one cgi.ebay.com.my/COMPAQ-VOCALYST-KEYBOARD-M-N-E03783001_W0QQitemZ300210062625QQcmdZViewItemQQptZPCA_Mice_Trackballs exept that mine is AZERTY). The plug was designed to be pluged into a specific Motherboard (that I trown away several years Ago). When pluged onto the old motherboard, this keyboard was used as the PC Speaker, it had a microphone (jack) plug and a hearphones (jack) plug. Is there any way to build an adapter to make that keyboard usable on nowdays computers (some USB or PS/2 conector) ? Thank you for any help you can provide :) (and sorry about my language, I'm french..) EDIT: some better pics can be found here: www.recycledgoods.com/zoom.aspx

breach loading sniper rifle

Welcome to this fourm, this fourm is about a breach loaders, if you have made any feel free to post (this dose not mean mag gun for the whole point is to help 1 shots/ sniper rifles get a easy load that is acurate fast im gessing at one point in time almost everyone made a 1 shot. But 1 shots have not evolved much, its all almost the same, pull fireing pin back and "muzzle load" it (with some exeptions of folding and back loading it)but wile loading the thing sometimes it fires, so it would hit your hand or your face (and my spring powered rifles have done so) , the solution? simple somehow get the thing to load without ever geing you to look at the barrel, sniper rifles usaly have it hard for they have long barrels (not including mepains) and take a long time to muzzle load the bullet. a faster way would be to breach load itso on this fourm posably post pictures of ideas you have of breach loading and if it somehow makes it more acurate. but just no old mag guns for the idea is to help make a fast and easy way to load. example this sniper rifle i made heres a video

can i charge 10X1.2v 3000ma rechargeable batteries in series using a 12 volt 400ma current ?

I am building a r/c tank and i am using 30 1.2v 3A rechargeable nimh batteries. now i have tried charging them individually in my energizer battery charger, but they seem to get extremely hot (75 celcius) when i charge them for 2 hours. now in the tank i have these batteries in 3 battery packs that hold 10 batteries each and i want to know, if i put a 12 volt 400-500ma current through the battery pack, will that safely charge them without damaging them? recently i tested one of the hot nimh batteries out of the charger with my multimeter, and it read that the battery had 10.28 amps in it and had1.2 volts which is anbormal (exept for the voltage).also i was wondering, is it posible tocharge these packs which once run in parrell give a voltage and current of this (10X 1.2 =12 volt 3A) X 3 packs in parrell =12v 9A can i chareg all of those at the same time, or must i charge one pack at the same time now before you say anything ill just add that these are individual batteries that i have placed inside a battery holder pack, also ill add that i wont buy a sla battery as ive used quite alot of money on these batteries already and lastly, i am not going to go buy a 10 battery charger as they cost way too much, unless sopmeone can find one online that costs under $25

Automated Single-Picture conversion for Anaglyph (3D glasses) except "Lasso3D"?

> http://en.wikipedia.org/wiki/Anaglyph_image//EDIT:I foundBas-Relief Demo ( http://www.3dphotopro.com/software.html ) which is great and allows most things i need in the demo version :-) It just needs a depth map, which I draw manualy by setting the brush transparency for different layer or drawing closer areas brighter.Still, I am open to any other program suggestions! :-)Hello,I am currently trying to convert a few photos, just so the people in front look further infront. I know how to do it manualy (cut objects infront, smudge hole, paste a bit further to the right, repeat layer for layer..., then i join the original image and the new one with AnaBuilder / AnnaBuilder / Zanag Z-Anaglyph) but I am looking for a program to convert the pictures, since its just taking long for not-so-creative work.Exept a bunch of totaly automated 2d-to-3d programs that work only on a limited number of images but are great to test anyway(xpounded.com Auto3D, Neurosys Anaglyph)I only found xpounded.com / Lasso3D (By Robert Spoons) where you roughly select the objects infront and the software does the rest.Its working good, but only for screen-sized resolutions, since no scrolling is possible :-( Thats a downside, since I want to print the images with a higher resolution.Does anyone know another (freeware?) tool or a simpler method in psp or gimp to convert images?xpounded.com / Lasso3D (By Robert Spoons)Thanks in advance for any help & ideas!-Marcus

Knex Firepower Standard

Hello everyone I (like alot of my freinds) get tired of... oh why dont you just search "Knex gun" and look at the mini descriptions and read them all, or maybe most and think what alot have us geting tired of, Go ahead! see you in maybe a min or 2? just click back or whatever to return here! and continue from where you last read.Welcome back! Do you see what what I'm talking about? well there are two things and if you did not notice these things feel free to look again!And what is Sypran talking about? (drumroll) the Quotes "It's very powerful" "easy yet powerful knex gun" "gun shoots about 60-70 feet" "this is a very small gun but will fire about 50 feet" "A deadly knex gun" and that is just the first page! i could go on for hours (ok maybe a long time) of coppy and pasteing these quotes!honestly i see to much "easy yet powerfuls" i cant realy tell what is powerful! so what do we do? well we take out time building maybe some and it turns to be not that great or it is great!, or we rush to see if KILLERK, Mepain, Extreme builder, Trainman2000 (i will always call him that >=D)You (aka mykhailo),Perfect duck,loosewire,Dsman19(i cant rember numbers) Oodalumps, am i forgeting anyone? (tell me if i am) has any new ideas/guns.so what do we need to do? WE NEED A FIREPOWER STANDARD something simple like 1-20 and how to mesure it, in earth science they clasify rocks hardnes by what they scratch (nail 2.5 glass 5.5 and so on) we need it something like paper peice, but not that for some guns have alot of power but cant peice due to low velocity and or dull non sharpened bullets.also if you know anything about real guns the bigger the bullet, the more powerful =D but the smaller the bullet the higher peirce rateing (a 0mm would be the best peirce but little damage) so in other words the biger the bullet (45 cal example) the more stoping power it will have but less muzzle velocity (pierceing ability) wile the smaller (7mm) the knocking over/stoping power is anything to be desired, but it will have high muzzle velocity so peirce through more materials. yet with (if it was at all posible) a 0mm (or basicly nothingness) in theory could peirce through ANYTHING but would not stop the person or thing in any way so the same pricable stands for knex notice the shotguns that shoot conectors (or killerks magnum with his amo) create a biger bang sound, they do more damage, but need more force to get all that mass through a paper wile the ones that shoot sharpened (like gorkem's) or greens can peirce paper with ease. so not only will we need a firepower test but a peirce test. peirce is easy enough its velocity and ammo size and a variable if it is sharpend and we have an instructable on how to determin bullet speed. power is bullet size+ extentions (killerk's magnum ammo like) also a little velocitybut the system needs a ruberband standard to keep in mind no putting on more then the systems amount of ruber bands or size of ruber bands (i know people will do this anyway)so what am i basicly saying in this topic? easy please people we need records of bullets speeds for sertain bullets with your guns it is easy since most of you seem to have digital cameras and there is an instructable about it. also we need to know a standard RB cause i dont know whats standard in the rest of the world besides USA and even then i dont know if its standard in the other states (they say americans like everything bigger and sadly sometimes it's true)i have tested some guns out and lets say that stong yet easys from the first page so far are low... so maybe we need a test for difrent kinds of guns! i have seen rifles that fire like a medium pistol (for they are exept they have a longer barrel, bipod, stock, and scope) should these even be given a 6 out of 10 in every catagory? or should it be 2 outa 10 for rifles. if lets say we got a standard of ruberbands to be 2 (not including trigger ruberbands) that where (makeing this up) a circumfrance of 3 inches, end of barrel being 2 feet away from camerathe adverage gun (all makeing up still) 25 feet with white shooting 1 foot per sec, does not dent an empty can. bullet speed of 5 feet per second with a max range of 40 feet (acurate ranges ppl use mesuring tape) with a white bullet that dents and peirce through an empty can we can conclude that the gun has high peirce rate but beter then normal power rateing. so a 7/10 for peirce if best was a max of 60 ft bullet speed of 10 ft per sec and white rods then it could have scored higher.one day when i search "knex gun" i want to see "my first Sniper!, it scored a 7/10 firepower and 8/10 pierce with 100ft range" cause then i can say that is a good gun I'm going to build!
