I need someone to design and point me to the correct parts for a circuit that will use 2, 5V LiPo batteries that are rechargeable, in a circuit that is built to run a memory bank. Basically a CMOS circuit, very low current draw. I need the LED indication to replace a battery. The switching between them has to be fast enough that the memory doesn't lose the program on it. $100 to the first person with a full parts... Source: over 3 years ago
My go-to site for a quick simulation, and pretty schematics (that sounds almost NSFW) is circuitlab.com. Source: over 3 years ago
If you have a 10 band EQ pedal into a flat amp you can hear what these frequency shapes sound like. Once you understand what these preamps are doing, then you can learn about the electronic side, read the schematics, and start designing / playing with your own circuit mods / designs. A circuit simulator (like circuitlab.com) would be a good place to start doing that. Source: almost 4 years ago
Tips if you want to check is circuitlab.com. Its very fast and easy to check. Source: over 4 years ago
I used circuitlab.com to simulate this behaviour, to obtain this image, which show what happens to the voltage across a capacitor when it is charged by passing a constant current through it. Noite that the slope (gradient) of the plot is constant during the entire time current is passing. Source: over 5 years ago
General Coding Assessment (GCA): the harder of the two, but manageable with preparation. It's done on CodeSignal, either in person or online. To prepare, practice DSA questions on competitive programming sites like LeetCode, Codewars, and CodeChef for 1–2 weeks, and you should be in good shape. - Source: dev.to / 27 days ago

Plain BST. Fine when input is random or the problem doesn't require worst-case guarantees. Tree problems on LeetCode typically assume balanced input and don't ask you to maintain balance yourself. - Source: dev.to / 4 months ago
Your preparation should not be random. Platforms like LeetCode, Codeforces, and GeeksforGeeks are tools—but what matters is how you use them. - Source: dev.to / 4 months ago
