    Electric Chipper Shredder

    Ok, not really sure exactly where to put this, so I'm putting it in here. I'm looking to turn a gas chipper shredder to an electric. I was thinking of using one of my extra DC motors. But then I had a thought that they have some that run off 120, so I was wondering if I could use a 5 hp AC...

    EIG battery issue

    I had my EIG cells sitting on the shelf for a while. I pulled them out to check the voltage etc. While I was carrying them I could smell a strong smell, that sort of smelled like freshly painted nail polish. I thought maybe it was something in the house. But then when I got to the carport, I...

    Affordable LiFEPO4?

    Ok, I have been busy trying to research and get my Lipo pack built for most of this year, so I haven't been paying attention to LiFEP04 lately. Who is selling decent sized (in terms of Ah) life packs nowadays for a decent price. I know thundersky's were always the cheap deal, but they tended to...

    Cycle Analyst problem

    Ok, not sure exactly where would be the best place to post this, but I figured here is as good a place as any. I bought a Cycle Analyst high current version. I just got it installed on my motorcycle 2 days ago. I went to test it out yesterday and it started up with the key switch turning on...

    Where to get large heat shrink

    A few years ago I got some really large heat shrink from Gary. It was 9" wide and great for wrapping battery packs. It is almost more of a plastic than a rubber like the regular heat shrink for wires. Does anyone have any idea where I could get more of this? Or an idea of what it would be called...

    3D scanning

    I tried to do a search to see if this topic was covered before, but didn't find anything. Has anyone here had any experience with 3D scanning? Or more specifically with ReconstructMe? We found some info on using an Xbox Kinect device with ReconstructMe software to scan objects into 3D. After a...

    PMAC-DS (ME0913)

    I'm looking at getting a PMAC-DS (ME0913) motor and was told that they were near impossible to set up and that we should pay an extra $1000 to have them set it up for us with wiring and programming. How hard are these to program? Is it really worth an extra $1000 for them to do it? Looking at...

    KU123 controller error message

    Got a friend who is using a KU123 controller on ebike build and just asked me what 8 blinking red lights mean on his KU123 controller. He said it happened mid ride, and made sure there was full charge and checked all the wires to ensure there wasn't a short. I've been doing searches on this, and...

    Solar Thermalsyphon water heater

    I just got back from a trip to my mom's house in Hawaii. When I was out there I built her a solar thermalsyphon water heater for her. I built a 2x4 frame with a 3/4"plywood backing. Laid down some insulation and covered that with some corrugated metal roofing. Made a grid out of copper tubing...

    Lipo setup for 24v system?

    My brother is trying to build an electric bike with his daughter and called me asking about what lipo setup would work. I'm just getting into lipo myself, so I had to take a look at it. 3.3v looks like it would be just under with 7s and just over with 8s. Which route would be the better one to...

    2 Agni 95R motors or an AC 20?

    For a race bike application, what would be a better choice, 2 Agni 95R motors or an AC 20? I've heard mention before, but haven't seen the end result, has anyone had any success with liquid cooling either of these types of motors? Edit: This conversation is being continued as a build...

    Reel Mower bicycle hybrid

    Does anyone remember the reel mower bicycle build that was done a few years ago? I have done a bit of searching on ES, but can't find any mention of it. It was something like this: I just had a friend mention that he wanted to build this. I remember something about some issues that the...

    Electric trike

    I picked up an electric trike that someone else had built and I'm trying to get it running again. The SLA batts were really dead. 2 of the batts were down to about 4v and the other 2 were down to 0.5v. I put them on a charger and got them up to 11v and then I threw them on the desulfuring...

    Looking to do an exercise bicycle generator similar to what Forrest did in: http://endless-sphere.com/forums/viewtopic.php?f=41&t=30175 We got an old exercise bike that you can use both the pedals and the arm things. I have some smaller motors in a box that I got from someone long ago. Looks...

    Modified Wind turbine

    I'm trying to work on some options for collecting bi-directional wind power coming through a tube. I want my prop to always spin in the same direction. The problem is that the wind will be alternating directions in and out of the tube. With a regular prop, this has the potential of spinning...

    Solar Battery Maintainer

    So I borrowed 5 battery maintainers from Terry, better known here as gasfreeearth. I'm doing some solar experiments in the back yard trying to slowly revive some old batteries. I set them up in parallel to get an actual charge of out them, compared to just a maintaining power supply. One of...

    switching to brushless setup question

    A buddy of mine called me in the middle of the night last night with a question about switching from brushed motor setup to a brushless set up. Granted, I was already asleep when he called, so my mind is a little groggy on the conversation. I told him I would check around and get back to him...

    Thermosyphon Solar Water Heater

    I have been doing a bit of searching for ways to help my mom cut her $500/month (she has multiple houses on her property) utility bill. It looks like one of the easiest things to do is to build a few Thermosyphon Solar Water Heaters for her houses. She lives in Hawaii, so she gets really good...

    Question on ratings

    I just want to make sure that I'm getting this right. If a system is rated at say 240 watts, that is 240 watts per hour with full sun exposure, correct? So in a day of 6 hours of full sun exposure that system will give 1440 watts?

    EIG 020B battery pack

    Ok, I have recently found out that I am one of the few members that have these cells. So I thought I would do a thread on the basics I have for them and possibly try to answer any questions people might have for them. I don't have much test equipment other than some of my builds, some CAs, and...

    replacing brushes on a mars motor

    I got a buddy that bought a used bike from electric Motorsports. He said he had it for a while and was hot dogging in front of his house and the bike suddenly cut out. When I was checking through it, the power wasn't making its way through the contactor, and it got really hot. It seemed like...

    Smoked a switch

    I'm waiting on parts for my newest build. So in the mean time I pulled out one of my old builds, the raleigh. The pouch LiFePo 48v battery pack had swelled really badly a while back, so I had stopped using it. The other day while pulling parts out of my storage I pulled out an older 48v...
