Hi all,
I am new to this forum, and relatively new to electronics. I have dabbled but really looking to learn more. I figure one of the best way to learn is by doing. A simple project has presented its self in the form of a battery (AA or AAA) flashing red LED for a non functioning CCTV camera, for the block of flats I live in.
I have done a bit of initial research and come across joule thief’s. They sound good because the battery life will be long.
So my question is; I found two different circuit designs. But not sure which one would be best to try and build. If anyone has any ideas that would be great!
This first one seems nice and simple, however the circuit diagram is a little blurry and being new to this I am not 100% what it actually says:
The second seems a bit more complexe, but the information is much clearer. (I would be building this without the PCB FYI, Just wiring it up with wire and solder):

I will have to buy all the components as I don’t have any old computers laying around. Was thinking I’d buy the bits from ( I live in the UK): https://www.mouser.co.uk/m_Home.aspx
If anyone has any insight into which is a better design.
Or if you have a completely new design that would be better that would be great.
Really just looking to get a parts list together, and start soldering, but thought it’s always best to see if anyone has any advice before I dive in!
Thanks in advance, I look forward to learning more about electronics.
