I took an existing idea and changed it to work with my existing hardware. I'll update this tonight as I move forward.

I wanted a way to power my breadboard and actually power a 12V DC motor, the one in my robot, without using the battery and where I could depend on it. I could get one of those big bois (variable power supply) but they're so expensive.

This is the basis for my project:

NOTE: I have mad respect for actual electrial engineers. THEY DO MAGIC.

EDIT: I ALMOST FORGOT THE DIODE. IN4007

This is what can happen when you overload a power supply and don't have a diode to break the circuit:

Electric vehicles are no longer rare—they’re mainstream. From homes to office parking lots, more people are making the switch. But with EV adoption comes one critical requirement: a safe and reliable charging setup.

And here’s the catch—installing an EV charger is not like plugging in a kitchen appliance. These units draw heavy current, and when the electrical system behind them isn’t designed properly, the risks add up fast.

This is where professional electrical expertise steps in. At Three Crowns Electric, we’ve seen plenty of DIY projects and cheap contractor jobs go wrong—burnt wires, tripping breakers, and panels pushed far beyond their limits. In every case, the “savings” didn’t last long.

The truth is simple: your EV charger is only as good as the system powering it. And that system needs an expert hand.

1. It’s More Than Just a Socket

A Level 2 EV charger typically runs at 240 volts and can pull 30–50 amps. Compare that with your standard microwave drawing 15 amps, and the difference is obvious.

Drop that kind of load onto an outdated panel, and you’ll end up with constant breaker trips—or worse, overheated wiring. Professional electricians assess your electrical system first, then recommend upgrades like dedicated circuits, new breakers, or even a panel replacement if needed. That groundwork prevents dangerous surprises later.

2. Safety First, Always

Electricity doesn’t allow second chances. A loose connection, wrong breaker, or undersized wire can mean fire, shock hazards, or equipment failure.

Licensed electricians know the code and follow it—because every safety rule exists for a reason. At Three Crowns Electric, we test, ground, and inspect every installation thoroughly. That peace of mind may be invisible day to day, but when everything runs smoothly, you’ll be glad it’s done right.

3. Every Property Is Different

Your neighbor’s charger install might have been simple—but your home or business may come with its own quirks. An older electrical panel, a long wire run to the garage, or an already overloaded commercial building can complicate the setup.

That’s why cookie-cutter solutions don’t work. Professionals customize every installation for safety, convenience, and long-term durability.

4. Permits and Compliance Made Easy

EV chargers almost always require permits and inspections. Skip them, and you risk insurance denial, fines, or even being forced to rip out the charger.

A professional electrical services like Three Crowns Electric handles everything—permits, inspections, paperwork—so you get a fully compliant system without the red tape.

5. Efficiency That Lasts

A poorly installed charger doesn’t just put safety at risk—it can also waste energy. Long wire runs, mismatched breakers, or imbalanced loads all affect efficiency.

Professionals design installations that minimize waste and keep charging times consistent. Over years of daily use, that efficiency saves money and reduces wear on your system.

6. Built for the Future

EV technology is evolving quickly. Maybe you’ll add a second charger, or upgrade to a faster unit down the road. A short-sighted install today could mean costly rewiring tomorrow.

That’s why at Three Crowns Electric, we think ahead—ensuring your setup can handle future expansion without major rework.
