I stumbled upon a go kart motor in my shed that my grandfather was going to use to make a go kart. It was supposed to be built when i was 12. I'm 21 now. My grandfather has passed on. The go kart frame was stolen. I want to put this motor to good use. The problem is that I don't know what to build to use it. I want to build something more than a go kart. if i wanted to go for a drive i would just take my car. Lol :P Any suggestions? Motorbike? Atv with caterpillar tracks? Help me decide and I will post full instructable!

Howdy Folks, I'm doing an art piece that will require many small motors and know nothing about them or even where to start looking. What I'm thinking is something similar to a clock that will spin 3-4 roundish cast paper layers (one nests inside the other) on the same axis but at different speeds and maybe different directions. Initially I had thought about using small battery operated clocks but I need something with more options. Each layer will be lightweight (made of paper) and the speeds will be relatively slow. Since I may need about 30 of them I'd prefer them to be inexpensive. And, since I'm new to this area of knowledge I need them to be relatively simple. Grateful for any suggestions! Thank you in advance. Cheers.

I am extremely close to finishing Grathio's Secret Knock Detecting Door Lock (https://www.instructables.com/id/Secret-Knock-Detecting-Door-Lock/). I am about to mount to my door, but unfortunately the clamp (step 3) has not been working out for me, and in no way will the motor be strong enough to turn the lock. Any other suggestions on how to hook up the motor to the door? FYI: my casing is entirely different from that of his instructions. Thank you!

I am building a small, plywood boat and looking to power it. I have built many projects made out of wood but never anything mechanical. I am looking for advise from people who have done something similar. In the image I attached there are three problems I face. 1 and 2) To transfer motion from the circular saw to the prop's axial I was thinking using something similar to a bike chain. What parts would you use to do this? 3) How would you secure a prop onto an axial? I am not looking for this to be a fast or anything. Just more of a practice project. Thanks!

Any suggestions on how to build a rotating sunflower (span of about 3 or 4 feet) to hang on a wall (sunflower will be made of fabric or perhaps a sticker image on foam)? It's in front of a series of large windows, so I'd like it to be solar powered. I was thinking of working with toy motors, but I think the RPMs would be way too fast - I'd like it to move fairly slow, maybe completing a full rotation in about 10 seconds or so. Any suggestions on what type of motor/solar combination (and where I can get these items) would be great. I'm trying to mount these on walls (multiple numbers of them in different sizes).
Okay, Im thinking of turning my bicycle (a "Quasar Bounty") into an electric bike. it already weighs about 30-40 lbs. And I want it to go at least 30mph. Can someone please suggest a motor I can use, and what battery I should use? Thanks, Michael McPherson (mmcpherson4)

Hello! I'm, building a standard H-bridge motor control circuit, but I can't find the power MOSFETs I need. I have a schematic which uses IRF630 / IRF9630 MOSFETs, but they'll only handle 9 amps at 12 volts. The motor I'm controlling will require a continuous current of 25 amps at 24 volts, with a max of 45 amps (if the motor is in the locked rotor condition). I'd like them to reach "fully on/off" with +12 volts at the gate. Does anyone have suggestions? I'd prefer built in electrostatic discharge protection, but beggars can't be choosers, so I welcome any suggestions. Thanks to all!
Question by charlene.wintersrecos 3 years ago | last reply 3 years ago
Hi Folks!I would like to propose a new topic, please let me know if it's already hiding somewhere on the site and I've missed it. This might require a whole section to handle all of the possible separate threads, not sure...It's called "What Should I Do With This?"...I have several weird items in my possession that I KNOW have greatness lurking within them, but I'm at a loss about how best to unlock their potential. I'm sure lots of other folks are in the same boat. So here's the idea:We post a photo and/or description of the item, and ask what to do with it. Readers can offer suggestions (hopefully something besides "give it to me!"), advice, etc. Then when/if the advice is taken, we make an instructable, or at least reply to the thread with the results.For example (I'll post pix if I can), I have an ancient external, ~5 lb serial-port CD player in a serious metal housing about a foot long with a power supply built in. What's especially nice is the huge sticker along the side of the silly beast that says "PORTABLE" in huge block letters. It's crying out to be the platform for some device, just not sure what.Another item is a big Fostex 1/2" 8-track reel-to reel with a bad (and I'm told, prohibitively expensive to replace) tape head. So it's got a smooth, quiet & powerful motor (or two), eight analog meters, lots of RCA in & out ports, plus switches, leds, and pulleys for aligning and running the tape. I'm thinking a belt drive for a Van De Graaf, maybe some random dancing needle meters for various projects...See what I mean? I'm sure somebody has some ideas for the bits and pieces I haven't even mentioned, or a better way to re-purpose the entire apparatus without reducing it to it's components.Maybe if somebody was looking for input and got a suggestion that they thought was amazing but outside the realm of possibility for them, they could offer to send the item to the person who made the suggestion (if the recipient paid shipping, of course). But for the most part, I think sharing ideas would be most valuable.What do you think? And, perhaps even more importantly, what should I do with the stuff described above?Thanks!!Mike

Question by CrawdadMan 9 years ago | last reply 1 year ago
I have a small antique desk fan that I am refinishing the art deco base on. Now keep in mind, in another life I was an antique dealer. I know messing with it drops the value, however the base was all ready badly corroded. The motor runs, though rough. I think it is most likely bearings, and or possible winding's could have a small short, though that is doubtful. Lubricant for the bearings? And keep in mind cleaning it with aggressive chemicals like acetone could melt the varnish off the winding's, then I'm really hooped. Now the obvious would just be to replace the motor, but pieces like this were built not to ever be opened again, at least without hope of putting them back together the same way. Thanks

Hi everyone, Does anyone have any suggestions on how I can slow down the roatational speed of a 14.4V DC motor? Its come out of a cordless drill and I have another project to put it to use but it rotates too fast at the moment. I have 2 options: 1) Use a variable resistor to slow down the speed 2) Use a gearing system In an ideal world I would prefer to use the variable resistor, as then I could change the speed of the motor quickly and effortlessly. Mechanical circuits are not my best skill and Ive already burnt out a cheap potentiometer (presumably too much current?) so I need to think more inteligently about what the design should be rather than just bolting components on the side of it. If anyone has any ideas please feel free, im open to all suggestions at the moment. Thanks Mat.

Hi folks, So I'm putting together a workshop for primary schools kids on making things with recycled electronics. I'm trying to think of a circuit which each child could reliably get the pieces to make (I have a big pool of bits, and we'll be asking them to bring in stuff) - so the bits I reckon we'll get a lot of are resistors, capacitors, switches, little motors and LEDs. Can anyone think of something simple you could make out of those that might be fun to have at the end - some kind of simple moving bot or some such? I've done some of this kind of stuff myself, but my electronics knowledge isn't hot enough to figure something out by myself... Thanks! Brian

I'd like to add a small motor to a hand cranked coffee grinder (Hario Skerton Coffee Grinder). It's conical burr style grinder that produces a consistent particle size (much more so than the mini blender, whirlly style grinder). I'll expand on why that's important when I build the thing. My problem is that is takes 10 minutes or so to grind enough coffee for two people. I'd like to put a motor on it. I tried spinning it with a battery powered drill, but the RPMs were too high. The burr spun faster than coffee beans could feed. I'd like a motor in the 60 to 120 rpm range. I still need to determine the torque required. Additionally, I'd like to plug this right in to a 110 outlet. Does anyone have a suggestion on an appliance I could scavenge or the type of motor I should look to buy? Thanks, Mike

I have acquired an old "Airspeed" Industrial air circulator or fan, which stands on a pedestal. It still works, but at only one, fairly fast speed and in one fixed position. As a project, I am stripping it down and restoring it, while altering the overall look to something more in tune with a Steampunk aesthetic. As part of this I am adding a brass worm-drive which will enable me to alter the angle of the fan plus motor assembly on the pole to which it's attached. I would also like to be able to adjust the speed, either continuously, or using set points ( slow, medium, fast etc.). The motor appears to be single phase and connects directly to mains 240V AC supply. There are no electronics at all in the current construction - I would guess that the unit dates to the 1950s or 60s? Can any one suggest a safe and reasonably simple way to set up a speed control system? All suggestions welcome, however banal - the more simply outlined the better. If you know of an electromechanical means of doing this, so much the better. Regards and thanks
