This video shows the automated soldering stringer making strings of polycrystalline solar cells (laser-cut pieces of polycrystalline solar cells) for 20W Photonic Universe polycrystalline solar panels.
Use of the automated stringer helps Photonic Universe eliminate potential soldering risks such as dry joints and other similar problems which often accompany manual soldering processes.
I am making one of those vibrating bugs using parts from a garden solar light. I have amended my description above thanks to a comment from legalizeshemp420 who pointed out it is an inductor I am replacing with the motor, not a resistor. Thanks again to him.
By replacing the inductor in the Solar Power LED circuit with a vibrating motor we can fabricate a vibrating bug which charges in light and vibrates in the dark, such as when a shadow goes over it.
This is NOT a Solar Popper or a BEAM bot but it is a simple hack to do for a solar experiment.
You could do further work to the circuit to alter the operation but the hack I have done seems to be the simplest and the result is fun.
Main Components
-
I used an Oral B Pulsar toothbrush as the donor of the vibrating motor.
You could also use a vibrating motor from a pager or mobile phone
Solar Panel and circuit board from a garden light.
I used a “Fence Solar Light” from a pound shop.
Main Tools
-
Tin Snips
Soldering Iron
Hot Glue Gun

Generally my projects are for my grandchildren to enjoy. OK, I enjoy them too. If anybody else likes them, that is a bonus. I like to keep my work as simple and basic as possible so that it can be copied easily and improved by anybody who wants to try themselves. I recycle or repurpose items rather than buy new and when I do buy I like to keep it cheap.
