What size motor and battery are needed to run a kiddie train ride weighing about 250 lbs?

I have a kiddie train ride that was designed to run by charging the track in order to run the motor.  I can't find the parts for it, I'm missing a transformer, and the tracks may be too corroded to conduct electricity.  I would like to convert this ride to run off of a marine battery and motor using an on off switch, or timer of some sort.  What size motor, and battery should i be looking for?  I have read that these rides use 5 amps to get started and 3 amps while running.

can someone explain to me exactly what a motor controller does in an electric powered bike?

Ok so i wanna build my first electric powered bike but i would like to do it all from salvaged parts or parts i will make. i am not looking to go 100mph or ride it for days at a time I would just like to built this first one to help me understand how it works. As of right now my biggest hang-ups are what does the controller do and can i make one, and how do i figure out how much power it will need in other words if it weighes 10 pounds and i wanna go 10mph i need a 12v motor (hope that makes sense) Thanks for any help Danny

Looking for a specific Instructable - Video effect with demo cycle ride to RadioShack.? Answered

Probably 18 months ago or thereabouts, someone posted a processing  technique to give an effect which I remember as similar to a blurred version of the David Hockney photo sequences, only on video.  He posted a demo video which I'm pretty sure was a bike ride to his local RadioShack.   I've spent a looong time trekking back and pushed the Instructables search engine to its limits, but no joy.   Can anyone put their finger on this Instructable for me?

Choosing drive motors for kids riding toy

I'm building  "robot horse" for my daughter, and have the metal frame mostly complete.  The plan for locomotion is to mount reversible powered 6" wheels to the outside of each hoof, and steer tank-style. My biggest challenge is finding reasonably priced, reasonably powerful drive motors for each wheel.  My issues are  1)  I'm inexperienced at specing dc motors.       A) I'm not real sure how to translate published specs into real world motion.  I don't know exactly how much power it takes to get this reliably moving over rough ground to a top speed of around 1 mph.  I also don't have a good sense of much voltage you can pump into a DC motors.  (IOW, should I be able to push 2 x the rated voltage for a quarter second to get it moving? Will the motors naturally increase their amperage at a constant voltage (and thus power) as they are resisted by torque?)  How much power will starting from a stop take?  What about a slight uphill slope?     B)  I'm not sure what form-factor is best:  Gear motor?  Gear motor with final drive belt?  I would like to use worm-gear motors, as I think it would be safest if the wheels didn't move when unpowered. 2)  Hunting around supplier web-sites, I see lots of $20ish gear motors that use 5-20W of power.  Great price, but would 4 of them make enough power?  (See #1A above)  Also, I see lots of fractional HP motors for >$100 that would unquestionably be strong enough, but would cost more than the project justifies.  I found very little in between.  Are there motors and gear boxes that could power this at a reasonable price?   Relevant clarifications and details: 1)  The horse is about 40" high at it's withers (shoulder) 2)  Frame is made of 1/2" square tube steel. 3)  Normal rider + vehicle will be about 150 lbs.  However, unquestionably, larger kids (or multiple small kids) will at some point hop on it and try to ride it.  At 250 lbs. rider+vehicle weight it doesn't have to go fast, but shouldn't burn up the motors. 4)  It'll be powered by a lipo battery pack that shouldn't have any issues with 20A+ max currents and can be sized as needed for voltage. 5)  I'd like to keep the motors and gears <$200 total, if possible. 6)  "Rough ground" = flat grassy turf or reasonably smooth gravel. 7)  Motors need to be reversible. Can anyone lend some perspective on what type of motors to buy for this?  How much power/torque should I look for?  Any advantages/disadvantages of any particular gearing style for this application? I am assuming that motors on each wheel are the way to go, but if there are any other power transmission schemes that would work better, I'm all ears.

Home made &quot;emergency lights

Many of the guys have spent hundreds of dollars to purchase "official" police vehicle lights but I'm thinking I'd rather tinker and make my own. I can probably do more with them this way then be limited to what I could buy commercially.

what is a good motor/alternator/generator to use for a bike generator that's cheap (under $50, preferably under $20)? Answered

I'm on a budget and the bike is going to be mobile so I need a cheap motor but I also need it to be light. The bike would be used to power a USB hub where any USB powered device would be charged or used. So all i need is 5 V. I don't think an alternator would work becuase they look very heavy and I would be riding about 10-20 mi. round trip. It must be light and as far as attaching it goes I intend to use an instructable on bike generators or just plumbers ties to attach it. The only instructable that met all the requirements I've named that I've seen was https://www.instructables.com/id/How-to-Charge-Any-USB-Device-by-Riding-Your-Bike/ . That motor was too expensive "We decided to stick with our Maxon 90, which was a beautiful motor, even though its cost was $275." . Thus the need for a cheap light motor to charge a USB driven device. By the way, thanks for everyone that has posted so far!

How can I make a biodegradable adhesive in a paintball-like form-factor that's durable but would break if thrown.

Scenario: you're riding your bike. A car cuts you off. You have a little hopper full of these balls and have the presence of mind to get one out and throw it at the car. It sticks to the car. When the driver gets home, he sees it. Inside of the clear adhesive is a laminated piece of paper or something durable with a link written on it. The driver goes to the website and reads instructions about how to be a better bike-friendly driver. They wash the adhesive off with no damage done to the car. They become more conscientious drivers.
