Unferium- I think you’re referring to a DC-DC charge pump. These might not be ideal for a high current/ long duration load like a motor but you could make it work! ( : maybe PWM would be easier to implement with that configuration, I’m not sure. https://en.m.wikipedia.org/wiki/Charge_pump

In Level 2, the vehicle is plugged into a 240-volt power source at home or an outside charging station. This takes 3.5 to 7 hours, according to the firm.

If you want to build an inventory then my recomendation would be a hamfest. It’s cheap like the internet but you get to be there in person, see touch, feel, taste (ok, don’t do that) the merchandise in person. Best of all, if you don’t mind doing some manual sorting (ok a lot of manual sorting) there is a very good chance that somone will give you a large box full of components for free. That’s right, FREE!

Electricity stopped for 2,600 customers west of downtown Hamilton two Wednesdays ago after an unfortunate meeting of a bird and high voltage electricity.

So what? I would have killed for a shoebox with $30,– worth of Aliexpress modules when I was a teen. The stuff you can do with an ESP32 or even an Arduino UNO – while mainly focussing on coding and not debugging giant analog circuits that cost you your last penny as a kid.

The two projects will permit Ontario to sell electricity to U.S. customers when surplus power is available and the Nanticoke switch yard will have a hand in stabilizing the system.

Abstract: Downhole tools including a wellbore isolation device that provides a plurality of components including a mandrel, and a slip assembly comprising a plurality of slip elements including a slip wedge and a slip, wherein an element of the slip assembly is composed of a degradable metal material, and wherein the slip comprises a slip insert embedded therein, the slip insert having a compressive strength of greater than about 120,000 psi.

2019 will be a year of change for the semiconductor industry as new fields drive technological advancements.

Abstract: A magnesium-ion battery includes a first electrode including an active material and a second electrode. An electrolyte is disposed between the first electrode and the second electrode. The electrolyte includes a magnesium compound. The active material includes tin.

Being a lazy digital hobbyist, my knowledge of resistors are mainly 4k7 = pullup and 330 = LED no go poof

I had one of the big kits, like 100-in-1. Once I got through the fun projects, liked experimenting with the radio receivers and transmitters, fundamental electronics, even some simple logic gates and a memory cell. It ate through batteries like an SOB, remember substituting the bulb with the LED to cut down power usage. Good times.
