Solar charger
Description
This is a charger stand for a solar panel with a surface area of 13 x 15 cm. The stand is made up of 4 pieces. These pieces consist of a mount, on which the panel and its cover are placed (they are secured using glue), a foot and a small support beam. In this project I have soldered a USB cable to the panel to charge devices. It is appropriate to solder a diode to prevent battery current return, in case there is not enough light for the panel. In my case I used an ST4148 diode that I had on hand, although there are better options. Necessary materials: • Solar panel 13 x 15 cm. (Link: https://es.aliexpress.com/item/32906698984.html?spm=a2g0o.order_list.0.0.6d58194dcdS5RZ&gatewayAdapt=glo2esp) • M4x20 screws and M4 nuts. • USB cable (or another type if you prefer). • Anti-reverse diode (ST4148 or others). TIP: Use glue to join the two parts of the case, as if it were a sandwich with the panel in the middle. BONUS TIP: To protect the panel from bumps and scratches, I have placed a transparent plastic in the middle of the sandwich, which I have recycled from a box that I had at home. This is not necessary, but I would like to leave the idea as an extra contribution.
