Cool.video ,I don't have that one ,yet ,have you seen the fm modules ,on eBay I type in on eBay search fm modules ,and found some cool modules and some cool kits ,that might interest you.
The reason I believe for the 1 transistor being slightly different… without looking at the datasheets of the two types I would assume, that the 2 same have a very slightly higher base trigger voltage. That would give the oscillator a starting point so that the timing is near perfect.
I built a kit the other day here in the RV, parked in the Mojave Desert near Needles California (Home to Spike, Snoopy's brother!) It contained those blue Resistors that are so damn hard to read, so I laid them out, and tested each with my component tester, then soldered them in. Went like a charm, and the device performs as advertised, I now have a nice little oscilloscope built by me, for me. It works a bit better then the little one I built from a Nano, it does a job when needed but the new one is much nicer.
your videos are .

hi J…
this kit can work with 24 LED lights and 6 volts
'
hi J…
can this LED circular kit spin backward as reverse or not
One transistor needs to be deliberately 'out of spec' for the whole timing to have predictable behavior.
Oooo, I could stick this under my shirt to replace my dodgy ticker, then the kids will think I'm Iron Man, lol.
@Julian llett – What do you use to secure the PCB board? What is it called and where do you get it? That is a great idea! Thanks. 🙂
Hi. IT is posible to make IT slower flashing and how please
DEFFECT IN THE LEDS !!!!!!!!!!!!!!!!!
you should buy the Knipex 78 03 125 😀 great side cutter for fine electronic work

Very nice video Julian
How would you go about building Jerry Anderson's Terra hawks robot face with LEdDs?

Such a good tutorial many thanks

Great video, Julian. I remember back in the 90s when blue LEDs were expensive, glad to see that they aren't anymore.
not mostly lead :/
