I have this falstad-circuit:
And here it is per request, as a SCH file screen:
I'm trying to use a 555 astable to convert a variable AC with maximum of 12V (coming from Bicycle Hub) to 8VDC, enabling me to store it in batteries. Additionally there will be an overcharge circuit that redirects the current to the LEDs in case the batteries are empty.
Here are a couple of questions:
- I wanted to know if what I have done here is correct.
- I would like to point out that when I replicate this in tinkercad the simulation fails.
- And when importing the BRD to Eagle, the connections seem to be recalculated and what I get, might not produce the appropriate result.
- Why is the current produced no longer stable when I connect the LEDs?
- Is there any other option to achieve AC to DC for battery storage, with the AC coming from a HUB?
- Would this circuit work in reality?
Simulated in LTspice, falstad and tinkercad and by altering the zener the circuit drops the output voltage successfully.
Here is a LTspice screen (yeah the naming is different.. yada yada):
Also by increasing the C2 to 40uF the voltage comes even more stable and the leds don't flicker.
After a suggestion to use a regulator, i have done just that.
Now I will be looking into the charging circuit.
