![]() If I switch ON the switch but then OFF within 1 second (before the 2nd load is fired up) and then ON again: Then the 2nd load should NOT be fired up but load A should stay powered on. I made such delay circuit at age 15 - that's almost 40 years ago. This seems trivial enough: In theory a capacitor, resistor and a thyristor (or transistor, I need to play around) should be able to handle that task I assume. When I activate an old fashioned manual switch this shall happen:Īfter 1 to 2 seconds (ideally variable) load B will be ADDITIONALLY powered up.Įnd result: Both loads are powered up and shall STAY indefinitely powered up (up to several days). So we are talking about roughly 1 ampere. There are two DC electric loads (both 12V, about 7 watt each e.g. The problem is that I need to play around to get a better understanding how transistors, thyristors and capacitors work together. No: I obviously did not find a good solution here. ![]() ![]() I stopped playing with electronic circuits at age 16 - my knowledge is somewhat diminished. Think of a DC power source, a switch and a LED lamp: I want to operate the switch online, and see how the LED is lightening up (online). Some solutions seem to show the flow of the electrons - that made me very happy And none of the existing solutions did that for me, or I am too stupid to figure our how it works, or they wanted a truckload of money. I need to see it working like a real life setup would work. I operate a switch and then want to see what happens (e.g. My product is essentially a simple light bulb of sorts and I need to simply test my circuit as if I have made a real one. I do not need fancy "plotting" and what not. "Free" not just in a sense of signup, but free = no or just very low cost (and the ability to save my creation). I have searched in the forum and in Google: but all online simulators that I found came up short regarding my specs.įree (or low cost) online tool. I won't be able to design the solution for my electronic device - but might be able to create a mock-up prototype myself. Nope, it's not an APP-controlled device that outsmarts you by factor ten it's a rather simple device that helps people with blue-light exposure problems (and yes: I am well aware that there are night-light blue-light-free products on the market). ![]() Yeah "Another damn LED light that nobody needs", you might think. German living in Latvia, studied engineering a long time ago, self employed (usually creating new domainsuffixes - such as ".berlin" - as in about to start a lightening device kickstarter project. ![]()
