Could someone tell me, how to run this motor (picture)???

Hello ... on the picture you can see a motor, that has 4 pins. I would like to make it run, but I don't know how. I don't know, if it's a brushless or brushed motor. There are no number, no part number ... and I think = I'm not sure, there is no magnet as well (I made a test with needle, but it didn't attract the needle). In my poor knowledge ... normal brushed motor has 2 pins, and all the brushless I saw, had 3 pins. but  I never saw a 4 pin motor. Any ideas ??? Thank you (in advance) for your help.

Born to Run the Oakland Marathon

On Sunday, I ran the Oakland Marathon, finishing in 3:54:29, and placing 215th out of 945 runners.  I know it's cliche, but I read Born to Run and got inspired me to run a marathon.  It's the best book I've read in years:  the characters (all real people!) are fascinating, the setting and story are fantastic, and it just made me want to get out and go.  Halfway through the book, I decided to run a few miles to the grocery store in the rain just to run out back, not because I needed anything. Prior to reading Born to Run, I had been running a 2-3 miles twice a week to vary my preferred morning exercise routine of biking or swimming (the kitesurfing season hasn't really started yet).  Running was something I did if I couldn't get to a pool or didn't have the time for a long enough bike ride; it was exercise I did while traveling and when there were no better options.  Born to Run made me question that assumption, and I decided to see how longer runs would feel. Over a year ago I read "You Walk Wrong", a New York Magazine article on going barefoot.  It convinced me that I should be able to go unshod, or at least with minimally foot coverings.  Why would 30 years of running shoe development be able to produce better results than millions of years of foot evolution?  So I bought some Vibram Five Fingers  to protect my delicate soles, and had been doing lots of hiking and a bit of running.  The difference between running in running shoes and Vibram Five Fingers was profound for me.  In running shoes, I typically stopped running because my knees and hips hurt, not because I was exhausted.  The Vibrams forced me to take smaller, faster strides without heel strikes, and suddenly I was getting closer and closer to being able to run long enough to catch exhaustion without any joint pain.  The concept of going barefoot was initially tough because of my flat feet and overpronation, and the possibility of re-dislocating a kneecap. I never went anywhere barefoot, and after I initially dislocated my kneecap in 2000, I was told by a sports medicine doctor that I should never walk without the aid of custom orthotics in my shoes.  However, barefoot websites and forums are full of stories about people's arches coming back, and how kids raised without shoes never have flat feet.  Amazingly, it's all worked perfectly for me.  I now run without my orthotics without any knee pain, and my arches appear to have (re?)formed.  After hopping out of the pool, I always inspect my wet footprints, and they now have distinct arches.  I wish I had taken photographs every day to plot progress. With the characters and race in Born to Run still fresh in my mind, I looked for nearby races to give myself some motivation and something to train for.  When I discovered that Oakland was holding its first marathon in 25 years, and that the route literally went through my neighborhood, I immediately signed up for the half-marathon and convinced Christy to do the same.  I researched training regiments online, and discovered many were 4 and 5 month plans; since I had 50 days before the race, I decided simply to run longer and longer distances at a comfortable pace, and not worry about a rigid structure.  I ran most of my miles on trails in the Oakland hills, and some on the streets, but all of them in my Vibrams.  During a practice run on the half-marathon course three weeks before the race, I completed the half in less than my target time for two hours and felt so good that I opted to do the full marathon. In the marathon, I ran with GEICO-sponsored pacers aiming for a 3:50:00 time (8:46 miles on the flats, and slower miles in the hills; course elevation PDF here).  Of the three pacers, one was running his 34th marathon, and the other two were ultra-marathoners training for a 200 mile race from Calistoga to Santa Cruz; their normal weekend run was 50 miles, so a marathon was like taking a break.  Running in a group is awesome and way better than running by myself listening to audio books.  On multiple occasions, I imagined that we were the hunters of a tribe out running down game -- water stations every couple of miles broke the illusion, but I still eagerly grabbed cups, and the community support was tremendous.  There were bands, drummers, DJs, and gospel choirs making music along the route; families with full brunch buffets setup in their front yards offering all the runners fresh fruit and homemade baked goods; and many people just thanking us for running in Oakland.  The second image shows all my runs in the 50 days leading up to the marathon.  The first 5-mile run on the chart was the longest I had ever run at that point.  While I was coming from something of a limited endurance background (I've biked 135 miles on a tandem from Boston to Provincetown in a single day), I didn't really know my limit.  At mile 23 of the marathon, I finally caught up to exhaustion, and fell behind the pace group.  The last three miles were painful, but in the last quarter mile, I couldn't stop grinning and felt like I might laugh and cry at the same time.  When it was over, I just wanted to sit down. I was aiming for a sub-4-hour marathon, and I'm really proud to have done that on my first try.  Everyone made fun of me for walking like a zombie the next day at work, and I have some pretty large blood blisters on my feet, but nothing that won't disappear in under a week.  Go and read Born to Run, it might inspire you, too. Christy says: I'd always had to run as cross-training for other sports (I swam competitively for 13 years) and ran when I needed quick exercise, but hated it - my joints hurt, and it just wasn't fun.  I was a distance swimmer and can hike nearly forever, but could literally swim farther than I could (or would) run.  The most I'd ever run before was about 4 miles.   I got my Vibrams with Eric, and really enjoyed hiking with them on my feet.  I hadn't run in nearly a year and a half (pregnancy loosens the joints, which made running feel even worse) so when Eric announced he was signing up to run 13 miles I was dubious.  However, I read Born to Run and was suitably inspired - I was in good cardio shape from swimming and stationary biking, and would happily hike 13 miles, so why couldn't I run that far?  I decided to go out for a 5k jog to see what running felt like in my Vibrams. Long story short, I accidentally ran 6 miles, stopping not due to fatigue or joint injury but because of a blister from a poorly-adjusted shoe strap.  I signed up for the half marathon that evening, and started taking increasingly pleasant runs through the parks and across the city.  I ran the half-marathon course with Corvidae in her jog stroller, stopping to feed her periodically.  Eric finished while I was on mile 8, so he backtracked along the course and met us at mile 10, by which time she was thoroughly done with this stroller nonsense and had migrated to the sling.  I left the two of them to their own devices and jogged the rest of the way to the finish, about 3:25 after I started in the morning.  Not terribly speedy, even given the breaks!  The next day the bottoms of my feet were sore, and one of my Achilles tendons was a bit inflamed - I'd describe it as having overused my springs - but even though I was limping, my muscles were still in good shape. My pace is still quite slow (I ran the half-marathon in 2:42, for roughly 12:26 mile splits) but it's frighteningly consistent - I negative split most of the race, and at the end discovered I still had plenty of energy to sprint past a dozen exhausted runners.  Clearly I didn't run fast enough or far enough, but I was specifically setting a pace I felt able to maintain indefinitely.  The weak link is still my feet!  While I had plenty of muscle and energy left at the end of the race, the bottoms of my feet were tired from use - more practice is necessary to balance out years of shoe-wearing.  However, I recovered much more quickly this time, and was able to run again by Tuesday morning.  No zombie shuffle for me!  Of course, this means next time I'll be running the marathon, and at a faster pace!

Increase running speed

I don't run very much. I never was all that good at it. Lately, though, I have found the need to improve that ability, specifically my endurance at speed. I can slowly jog a mile, sure, but haulin'-ass-away-from-an-amgry-man-with-a-knife-speeds don't last much longer than thirty yards, if that. I'd like to improve my overall speed if possible, and especially increase the distance that I can cover flat-out before I keel over. I'm not going to be running a marathon anytime soon, but I'd like to be able to get farther than average, as fast as possible, on demand. Any tips for training or proper form? I live at roughly 5400 feet, but I'm just a short drive away from 14,000-foot peaks. I would also like to improve my off-the-line times--in other words, acceleration. If I were to need to run between ten and twenty-five yards, I can do that at my top speed as is, but that speed is not as fast as it could be. I'm generally not even up to full speed until eight or ten yards past the line. Suggestions?

Does anyone know how to program a repetative motion robot (see description)?

This is mostly out of a theory and curiosity, but if I were to make a robotic arm and I wanted to make it do repetativve motions, how would I make It recognize/remember the movments and how would I make it perform them. It would be a direct teaching unit (meaning I would move the robot and it would remember the movments) so how would I make it run or hook it up to a computer and how would I program it with the direct teaching. If this impossible or extremeny difficult, please recommend a different technique. Please give me good, detailed instructions.

How do you execute multiples functions simultaneously?

Hi! Got a programming question today. How would I run multiple functions/execute commands at the same time? What I'm basically getting at here relates to games. Lets say you have a game where you have 2 tanks. An enemy comes into view, they both turn and fire, but at the same time. In the code I've been used to writing, it seems that if you were to achieve them doing this, commands to turn and to fire would need to be executed at the same time. I suppose you could write a function that would govern all of the motion for the game, but that seems like it might get bulky quickly, especially if its a big game. How would you  do this? Thanks for answering! If you answer specifically in one programming language or another thats ok, b/c I'm familiar with several! Just need something to set me on the right track here!

Has anyone managed to run BOCHS on a PSP SLIM?

The PSP Port of bochs was apparently ported for 1.50 Firmware, and no other, Making incompatible with the modern 5XX Custom Firmware. Does anyone here have experience on this and have you gotten bochs to run and at least got past the BIOS loading part? The reason i am forced to use bochs is because it supports All os'es out there, According to my tests, bochs Should be able to Allocate up to 41.2 MB of RAM on a PSP SLIM, but i can't get bochs to start on my PSP. When i start it it gives me the traditional error(that means that it is only for firmware 1.50) So i installed LEDA It stands for something, supposedly it allows you to run most 1.50 firmware apps on 3++ Firmware. Now it starts, It slowly fades out, like perfect And then after a few seconds it exits, no error, what i suspect being wrong is a configuration file. So If anyone got it to run, At least to the Bios loading part, Keep me updated, and post a comment. Thanks ~ReCreate

is it possible to make a paper engine that runs off of hydrogen if it really sturdy and cylinder is lined with tin foil.

Ok so i have this edea to make a small two stroke engine out of paper and run it off of hydrogen witch i will make with a large battery and water like a fuel cell. But anyways ive allready built the piston and teh crankshaft and the encasing well most of it but i wanted to get some opinions on it can anyone help me? i should put on here that its not just a single sheet of paper thick um each component is 10 sheets of paper glued and compressed over 24 hours but also im thinking that if i lined the cylinder with tin foil it would stop the paper from burning and also the explosion will be very very micro sized probably 2x times smaller than a fire cracker and the compression will not be much of a problem because it works more off of the just the force of the pop. Ok so um the paper is yes just ordinary printer paper you can get at walmart for $2.50 but i cut out the shape i am making about 10 to 12 times sometimes 15 even and glue them all then stick it under a couple boxes of clay i have that are about oh well idk but allot of wheight and when its done each peace is about 1/6 of and inch thick so basicly about the thickness of chipboard.
