Hello to all,
I write this letter with my head held kind of low. it’s that way because I feel that I failed in my task of building my kids a couple of cool toys for the summer. Designing, 3D printing weren’t the issue. The problem has been creating the circuit that powers these things the way I want to is where the trouble is.
You see, I’m barely an electrician. As in half the time when I’m looking at a wiring schematic I have to go online to see what the symbols represent. I have all the tools to build whatever I want, just not quite the skill to design an electrical circuit properly.
I’ve been watching a lot of videos of 555 timers on Youtube. For some reason I just cannot get mine to work properly. I’ve even tried a couple of transistors with resistors, capacitors and was unable to do that as well. I see many other videos of it working. I do the exact same thing but it’s not working for me for some reason.
What I’m hoping is somebody can help me out with the design for what I need. I think part of the problem is that all those flip flopping circuits are usually just powering leds.
My toys are going to need more than that. they’re going to have a couple of little Motors in them. Size is an issue. I want to keep everything small. I want to use some coin batteries that are paralleled together and then in series, or is it the other way around?
I’m going to put what my needs are and the components current/voltage draw is. I hope you can help me with a schematic drawing.
I will be using Coin Batteries, rechargeable Lithium 3V 11MAH. I can use several in series or parallel. What the circuit needs I will supply,
I want to use a mini tactile switch for on off MAXIMUM VOLTAGE: 16 VDC MAXIMUM CURRENT DC: 50 mA DIELECTRIC STRENGTH: 250 VA C (1mn) CONTACT RESISTANCE: ≤ 500 mΩ INSULATION RESISTANCE: ≥ 100 MΩ BOUNCE TIME: ≤ 10 ms.
I want 1 circuit output to power an electrical motor rated at Voltage 3.7V,Current: about 150 ma. Run time from 2 seconds to 4 seconds.
The second output circuit will need to power 1 LED, 20ma 3 - 3.2 v… I will also power an additional motor whole the led is running, Motor will need 2.7 - 3volts less that 100 mA
I would very much like after turning on the first output will run. Then shutoff when the second out turns on. After it turns off the system will pause for the same length as either output lines run for then start again.
Finally, I would like the system to have a delayed runt time or off delay. Total run time for 5 to 10 minutes.
Any help would be awesome!
