Very well said, CeaSaR. :smile:

So Postimage, eh ? If it works to link public images to public forums I may save them there; as 'Photobucket' used to be. Now, with 'Dropbox', got hurdles too.

Re: HEY Dacflyer! GIANT LED DISPLAY!

Suspected that they would want viewers to sign up... It is all about controlling you. I cannot even attach a screenshot of the red message "Sorry, the board attachment quota has been reached." when I try to attach a picture.

18 inches tall digits... Anyone needs them ?

Tried to attach a picture; and "the board attachment quota has been reached" message pops up. :x :x :x

Will this be ever fixed ? :x

Re: To evaluate performance of used 18650 cells...

Thanks, Len.
All that makes good sense. I did not take in account the cost of cells; just saw the frustration of picking a bad cell from a bin of charged ones that some do well and others not at the moment of need.

To evaluate performance of used 18650 cells...

A bunch of old, used, salvaged lithium cells of unknown capabilities. Need a load scheme to evaluate their condition. Like loading them at a certain current load for 1 minute; another load for 10 minutes, another for one hour. Measuring the voltage at end. Perhaps checking voltage recovery after a c...

Typical 0.1 μF bypass capacitor value...

Most data sheets recommend 0.1μF bypass capacitors next to power IC pins. They smooth any sagging of the supply for the current the ICs draw in normal operation, and absorb transients generated elsewhere in the circuits. What if that capacitor value is raised; would it be 'better' or non-detrimental...

Re: Aftermaster

Digital audio processing does wonders; but as soon as television/film producers find out that a gadget can improve the intelligibility, they will insist on raising the noises and distorted electric guitars they call 'music' background to make it worse. You cannot fix stupids abusing from sound effec...

Re: Need Some Feedback Please...

Clarity is important to teach.
Title could be 'Need some feedback about teaching online'.
All initial use of abbreviations and acronyms explained on a side column help novices.

Re: Detecting a magnet... from a distance.

Hi John. So far I reached a 3 metre distance detection, with a 39000 turns coil. Ideal would be at least 50 metres. Perhaps am lacking mechanical dimensions (length) for the coil core bar. :sad: And refuse to spend too much $ for experimenting. Whenever you find how they detected the sun's magnetism...
