Wireless Magnetic Lamp for PCB Holder
In the process of working with small components, it is very important to have convenient lighting. A table lamp does not always help to see the details. That is why this lamp was created.
I used a 300 mA Li-Po battery as power supply, this is quite enough for the lamp to work autonomously. But at the same time, the charger used allows you to work while connected to USB. I've been using my own chargers lately, they're very small and easy to fit into DIY projects and more... And the next version will be even smaller.
You can also use a fragment from the finished charger, which I have previously used in other projects, for example in
this one .

I used a very common TTP223 module as a switch. It in the "Off" modes consumes scanty microamps. COB-Led for this lamp is just 3.7V, which does not require an additional booster converter. Don't forget to close jumper "B".
You will also need 1 mosfet and a couple of resistors, in short, everything is very simple.
And yes, I almost forgot... Chrome marker paint works great as a reflector. This will increase the brightness by more than 30%.
I have previously published
similar lamps and showed them using a microscope as an example.
