I wonder if anyone can help me to get this circuit working.
Auto On-Off Solar Light Rechargeable
I am attempting to learn electronics (72 years), and I thought this circuit which I saw on YouTube would be a suitable one for me to make.
Wrong.
Several problems, firstly there was no schematic attached so I have attempted to redraw it.
Next, several of the components mentioned I did not have.
The circuit specified in 18 K resistor, but the nearest I have is 20 K. So I substituted that.
The transistor specified is the BC 547 NPN, I had to substitute a 2N2222.
Also specified was a four volt LED strip which I don't have. (I do have a 12 V LED strip). So I substituted a blue single LED hoping that that would be okay to test the circuit.
And finally the solar panel specified was 6 V, I used a 5.5 V unit which was the nearest I had 150 mA.
I thought all my replacements might be close enough to get the circuit working, but no success.
I'm still hoping it's salvageable, with some help.
Thanks
