Electronics of any kind are driven by electrical power, and this section is all about handling electrical power.
Voltage and Current
All starts with voltage and current - and the many ways to measure and monitor both.
This is the foundation on which tools like multimeters, oscilloscopes but also devices like voltage regulators, chargers and battery protection systems (BMS) operate.
Constant Voltage (CV) / Constant Current (CC)
At minimum, you need to supply a stable voltage to your devices. Neither a simple AC power supply nor a battery alone are sufficient because their output voltage fluctuates and may not even be at all in the voltage range your device requires.
You frequently need a constant voltage regulator that accepts a wide range of input voltage and provides a fixed and stable robust output voltage.
Batteries
Rechargeable batteries are a great power source. For safe operations, both charging and discharging needs careful monitoring and protection.
That’s what a BMS (Battery Management System) does: it carefully monitors both voltage and current to make sure you are not over-charging or drawing too much energy from your battery.
Slow Website?
This website is very fast, and pages should appear instantly. If this site is slow for you, then your routing may be messed up, and this issue does not only affect done.land, but potentially a few other websites and downloads as well. Here are simple steps to speed up your Internet experience and fix issues with slow websites and downloads..
Comments
Please do leave comments below. I am using utteran.ce, an open-source and ad-free light-weight commenting system.
Here is how your comments are stored
Whenever you leave a comment, a new github issue is created on your behalf.
-
All comments become trackable issues in the Github Issues section, and I (and you) can follow up on them.
-
There is no third-party provider, no disrupting ads, and everything remains transparent inside github.
Github Users Yes, Spammers No
To keep spammers out and comments attributable, all you do is log in using your (free) github account and grant utteranc.es the permission to submit issues on your behalf.
If you don’t have a github account yet, go get yourself one - it’s free and simple.
If for any reason you do not feel comfortable with letting the commenting system submit issues for you, then visit Github Issues directly, i.e. by clicking the red button Submit Issue at the bottom of each page, and submit your issue manually. You control everything.
Discussions
For chit-chat and quick questions, feel free to visit and participate in Discussions. They work much like classic forums or bulletin boards. Just keep in mind: your valued input isn’t equally well trackable there.
