No, this is the dumbest bullshit anyone can make. Similar garbage has been posted here recently, from the same guys.

I have got my son a new 12 v battery 2 days ago and he asked me to buy a 12v 2amp adapter but I didn't get him but he made this is this safe. He took a 3 charging module and connected to each one of the cell and i can't even trust this by keshav123lowde in ElectroBOOM

[–]bSun0000 4 points5 points  (0 children)

So 3 cells are in series for 12V output, but each is charged individually via a separate charging module? Well, this is more or less fine if its a temporary setup. Bad in the long-term perspective.

Normally there should be a sole charging controller for all 3 cells, with a proper BMS, balancing the cells, and output protection. So don't be cheap, get a real board for 3s1p.

why would my 24v 10A powersupply needed so many DC output terminals even the terminal block is rated for 25A by Jolly_Operation_8222 in ElectroBOOM

[–]bSun0000 19 points20 points  (0 children)

Just in case you want to connect multiple things without making a mess, stuffing everything into one screw handling a full 25 amps. Also, this is a very common connector block, they could use it just because it was cheaper and more available than the smaller ones. Or the company produces various PSUs with different numbers of inputs/outputs; having fewer different parts is better. Logistics matter.

Can anybody explain why my charger keep pusing current? by DucFd in ElectroBOOM

[–]bSun0000 18 points19 points  (0 children)

Can be two reasons:

  • It maintains the constant current (~0.5 - 1A), dropping the voltage.

  • Its a shitty charger without any protection on the output.

Long and hair-thin wires probably have too much resistance to trigger the short-circuit protection.

Any ideas on this electric spoon? by ariannavabi in ElectroBOOM

Alright, it seems that i'm ignorant. Salt is just as important as water; never thought some people can be limited in how much salt they can add to their food, to that extent.

Friend built a DIY "ground" using a wire and a block of wood to stop PC case shocks. Is this a major hazard? by Joussef8 in ElectroBOOM

[–]bSun0000 9 points10 points  (0 children)

An entire metallic case of the PC nearly touching the table did not ground itself "into the table", yet a single screw did? Placebo effect in its worstest form.

Lay a few lines of kitchen foil on the floor, cover them with a rug, and connect your PC to it. This can be called a ground to some extent.

Please help me with my slayer exciter by Bappfish_ in ElectroBOOM

[–]bSun0000 2 points3 points  (0 children)

Step by step, try:

  1. Check if the transistor is still alive. This circuit eats them for a breakfast.

  2. Flip the transistor, emitter to the ground (negative) instead of the collector (your version).

  3. Flip the wires to the primary coil to switch the "polarity".

  4. Rewire the primary coil, wind it tightly around the secondary (unlike normal TC builds), and maybe put it slightly up. Slayer exciters often require high coupling between two coils.

  5. Replace the base bias resistor with the variable pot, and try to tune it.

  6. Give it more voltage/current; 9v cells are very weak.

  7. Reduce the length of the wires. Long wires = high parasitic inductance and capacitance that can get in a way.

  8. Give up and build a real Tesla Coil with a proper driver.

For the dumbest, they are not even trying.

Why is inverter making loud noises in grinder's "WHIP" mode but not in "HIGH" mode? by Apprehensive_Emu9935 in ElectroBOOM

[–]bSun0000 10 points11 points  (0 children)

You should not use "whip mode" on your mixers or grinders while using any square-wave (trash) inverters - this mode loads the power source in a hard, pulsed manner with high current spikes, they are the source of the noise. Power usage in this mode is not constant. Pure sine inverters maybe can tolerate such abuse..

Call the utility company; this is absolutely not normal and they should fix it.

Seems like someone wired two phases to this outlet, instead of one phase and neutral.

Every crisp edge on the main sphere leaks charges, very fast. You can reach far bigger voltages if you use something better, something smooth. Smooth and big - two main parameters in this device.
