My take on a common component tester assembly

I bought a cheap and very common component tester, then started looking around for an enclosure. It's just too easy buying, so I searched for a throwaway box to upcycle. That's when I found a cotton bud box and concluded that they made a perfect match. I also had stock of a battery holder (3xAAA), and rechargeable cells, a single-pole switch, a boost converter (MT3608), and a cardboard inner core from a kitchen foil roll, which I cut down to size. The total build cost for me was about £6.00. This video is about its assembly and construction. *Please help me purchase more components for more projects/repairs.

In this video, I mentioned that 3 x cells = 4.5VDC wrong :( 3 x NiMH = 3.6VDC :)
