stepper wire refresher
Unipolar and Bipolar Half Coil, because we’re using less turns, doesn’t give us great low speed torque, but because of the low inductance, holds the torque out to high speeds.
Bipolar Series uses the full coil so it gives very good low speed torque. But because of the high inductance, the torque drops off…[Read more]

BEWARE OF YOUR CHURCH!
“You make the prefect point sola scriptura can push to seeking “expert” help (the Pope)”No, that is not the point I am making, but actually just the opposite.
Sola scriptura was used to REJECT the Catholic Church’s dependency on the Pope, and to state everything we need to know about God is contained in the Scrip…[Read more]

In general, hubs like Hubitat and Zooz Box (there are a few others) are the middle ground between Google Home/Alexa and HA. GH/A is late to the game with local control and are a bit more limited on integration (plus focus heavily on wifi devices, blah). They also allow Amazon/Alphabet to see what you’re up to and you’re subject to their whims.…[Read more]

I have collected about 50 18650 batteries, most new. I will be dropping comments as i go about my build process and learning. This about the strips that connect the batteries, shopping for a electrode welder not, looks like a 200 dollar expense to get something reasonable. China made so far, us made are crazy exensive.

This solution works, I’m running a johnson fitness 2hp motor on my drill press. I searched a week and only found a system on ebay for 60 bucks and 10 shipping. I just couldn’t pull the trigger. The horizon T101 treadmill driver circuit board is dective so not really worth trying to setup a pwm input. This ends up about 32 bucks. I am considering a…[Read more]

Brushed DC motors may seem less glamorous than their brushless cousins but they deliver reliable, proven performance that needs less complicated drive circuitry – keeping overall costs to a minimum.
Choosing the right motor for any given application depends on the specific requirements of that application. Is precise control of the motor’s pos…[Read more]

Car batteries are designed for huge and very intermittent loads (hundreds of amps for a few seconds with tens of minutes of charging in between load cycles). You want a “deep-cycle” battery like those used for 12V trolling motors and powering RV lighting. They are designed for long-term, low-current loads. 2 years, 1 month ago
