I have many gadgets

I have a large number of many electronic gadgets. Gadgets foe making music, making pictures, making other gadgets, light, smoke … You name it, I have to gadget. I gave up some time ago pretending that I would use all these gadgets, so simply try to delay purchases to see if I will lose interest in them, purchase second had, or purchase the worst knock-off Chinese versions I can find. I wonder if I should make a catalogue of them. With barcodes. That I can scan with my barcode scanner.
