Re: There was a fire at my house today while I was not home.

It's just for security monitoring of the yard, for the most part. I don't really expect people to come into the yard with the size dogs I have ;) but at least I can keep an eye on things remotely (and record it) if I need to. I can also check up on he dogs remotely while I'm not at home, at least wh...

Re: I'm having problems with my Tiny BMS

If the lights and stuff are also running off the battery the BMS manages, then the BMS is not shutdown, and is not the cause of the problem. What is the voltage at the output of the BMS (input to the controller) when the system isn't working? If it is the normal full charged voltage, then the BMS is...

Re: Turnigy Rotomax good pair with PowerVelocity controller?

You may want to check with the controller manufacturer to see if it can handle the eRPM of teh motor at the speed you want to run it at. Otherwise the controller may lose sync with the motor at some point, and high currents or stuttering or other problematic behaviors may occur. If you state the ful...

Re: MAC motor controller?

Open up the controller and see if it has more than one shunt. If there are four, cut two and now it's a 20A controller. ;) Probably it will have two or three shunts. Cutting one should take it down to around 27-28A max. Then you don't have to deal with finding a controller that works with it (potent...

Re: Using the Wangdd22 1500W 30A DC Boost Converter on an ebike

Basically you' just need a DP3T or DPDT-center-off switch that is capable of handling the maximum DC Amps you'll pull from the battery into the controller (or converter). The common contact pair of teh switch goes to the controller input. One of the outside pair goes to the battery. The other outsid...

Re: BionX Motor Issue

If the wheel does not have resistance when the system is off, but does when it is on, then the problem is probably not the FETs. IT is probably something the controller is being commanded to do. If the wheel had resistnace regardless of being on or off, then FETs would probably be shorted in teh con...

Re: Anyway of making the R martins from china sold on Ali express road legal in U.S.

Does that mean that if an existing car manufacturer went belly up (or perhaps was bought out and taken over in such a way they no longer exist), or that company somehow loses it's EPA registration/licensing, that suddenly all the vehicles on the roads made by them are no longer registerable?

Fixed the microwave; no fuses the right size/type, but had two 10A microfuses in each of some old PSUs, with holders. So I desoldered the entire holders, paralleled them, and put the quick-connect tabs from some of the wiring in the PSU onto that, so I could just plug it in in place of the regular f...

No leaks yet on the pipe fix. :) My brain kept working on the problem anyway (like it usually does) and realized that if I have further problems with the crimped/soldered "fix", I could desolder that entire branch, taking it's "T" out of the pipe along with the extension from that T to the next one ...

Re: A2B problem

Could be blown FETs in the controller. If your controller is external to the wheel, then disconnecting that from the motor would let the wheel roll normally. At least some of the A2B bikes use the Ultramotor, which has a built-in controller. If yours is one of those, then disconnecting the motor con...

What is that BMS's balance point set to? What voltage does it turn on the balancers at? What voltage does it turn off the balancers at?
