    Build a 5m rotor diameter

    Go to the forums on otherpower.com . They have tons of info on building your own wind turbine and even sell lots of the parts needed to do so. 5m blades is very large to start off with, though.

    Mobility Scooter upgrade

    I've been out of the mobility equipment repair business for a few years, but if anything, innovation in the industry is slow, so I imagine not much has changed. Yes, you can program the controller with a pc, or a proprietary device that mobility dealers have. Not much can be done, however, as...

    Dune Bug-E (Retro Build circa 2009/10)

    Frank! Man, I miss your site so much! No lie, it was one of my favourite sites for years. Your projects always hit a chord with me. Here's hoping that you get back on the building wagon!

    Off grid inverter used on grid

    Yes, you can lower your bill, but not the way you want to. Off grid inverters have no way to hook up to your house. You would need a battery bank and run things directly off of that. All that inverter you linked does is allow you to charge the battery bank with ac as well as dc and run direct...

    How much power to field coils?

    I don't know what you are going to use for power input, but let me tell you right off the bat that alternators are meant to run at very high rpm. Depending on what your power source is, it might be easier, smarter and more efficient to use a motor or dynamo.

    Revamping a used scooter

    1-yes, you can get headlight polishing kits at any automotive store. 2 -no, you can put as big or little battery as you want as long as the voltage stays the same. 3- if the motor fits, no new fork is needed. The increased torque at the fork would be so negligible. I would get a new fork if you...

    Can i install a other battery?

    Can't really tell from just the outside, but the chances that you can just add another battery to that controller are very low. I would confidently say that you cannot do it. The motor should be fine to take the extra voltage, but at only 500 watts, you will not likely get any more speed out of...

    Industrial golf cart turned into solar generator.

    I've been slowly accumulating power tool cells by collecting them from the battery recycling bins at hardware stores. Every one I've been to is happy to let me take as many as I want. Most of the time, the cells are useless, but often there is a broken bms or only a couple bad cells or sometimes...

    Would you be willing to crowdfund ES development?

    Just looking at the number of views this thread has, I'm curious if you might get a better response pinning this thread to the top of each page rather than making it a sticky. I know, personally, I skip right over all stickies and only found this by accident.

    increase static solar panel efficiency/output?

    Previous comments are correct. Keeping our panels, clean and cool, using MPPT and tracking are the only ways to maximize your panel efficiency. Yes, mirrors concentrated onto the panels will increase your output, but you have to constantly adjust the mirrors, otherwise they will shade the panels...

    Need Help - New Batteries Only Charge Halfway

    Coming from someone who sold batteries for scooters for years, I'm willing to bet it is the batteries, but they might still be ok. What you should do is first charge them each individually or in parrallel to balance them. Next, lead acid batteries like to be cycled a few times, especially when...

    Thrift Stores for Parts

    They are still predominantly brushed. In fact, Invacare, one of the biggest powerchair manufacturerers discontinued their brushless motors years ago. Some of the biggest players, Permobil, Pride, Invacare, Shoprider and Sunrise, none have a brushless option. Power chairs are so far behind...

    Thrift Stores for Parts

    Mobility scooters will have SLA in them and they will almost assuredly be dead. The controllers are useless as they are not modifiable. Sometimes the motors are ok, but they are always brushed and come with an electric brake attached that would be better off removed. The throttles are just a...

    I was given a Currie iZip 1000 series. Need help fixing.

    Going to have to change the controller and charger and batteries to jump up to 48volts. For that amount of money you can just buy a better scooter.

    Shared electric cars on the horizon

    Woah there! Calm down, comrade! Most people who use laundromats do so because they live in an apartment which is what is most readily available in a crowded city. Sharing things like cars is only a sign of poverty if you choose to view it that way. I live in a very affluent city which has bike...

    DIY Electric Assist Wheelchair

    I will tell you as someone in the industry, these systems are pretty much universally hated. They seem like a good idea because you can still use your chair manually when you want to, but switch to assist when needed. The problem is that the wheels add so much weight to the chair, that you end...

    Electric Hub Motor WIpe Hard Drive?

    This hasn't been a problem for years. You are probably worried because you are tinking back to floppy discs. Hard drives are not like floppy disks which used magnetic discs to record making them susceptible to magnets. Your laptop will be fine.

    Right, but he did say Sydney, but the one on the island is spelled Sidney

    Anbody in Canada with a Fedex Account Number?

    Wait, do you mean Sydney Austrailia or Sidney, BC?

    Anbody in Canada with a Fedex Account Number?

    Just call fedex and set up a pickup and delivery. You don't need an account. Or ask someone on Usedvictoria, travel between Sydney and Victoria is so common, I'm sure someone will be willing to pick it up for you

    New Electric ATV Battery Post Difference

    Sorry, didn't see your other question. You just need to get wire at least the same gauge as the cables already on the bike. It looks like 12g from the pic so anything that size or bigger (remeber, the smaller the gague, the thicker the wire)

    New Electric ATV Battery Post Difference

    That would work just fine! Honestly, though, you should just get the spade connectors (the ones that fit the new batteries) and cutt off the old rings. It will take 3 Seconds to do.
