One of our Maker is over in Shenzhen and did a fantastic write up of the electronics district, SEG Electronics Market –

“Ten years ago, Akihabara was the place to be for the latest electronics and knick knacks and components. I’m convinced the new place to be is the SEG Electronics Market in Shenzhen (although to be fair I heard there is a competing market in Korea that’s supposedly even better-the Japanese test-market their stuff there even before they try it in Akihabara!).

…Stacks of power supplies, varistors, batteries; ROM programmers. Atmel, Intel, Broadcom, Samsung, Yamaha, Sony, AMD, Fujitsu, every variety of chip. Some of them clearly ripped out of used equipment and remarked, some of them in brand new laser-marked OEM packaging.

…Chips that I couldn’t dream of buying in the US, reels of rare ceramic capacitors that I only dream about at night. My senses tingle, my head spins. I can’t supress a smirk of anticipation as I walk around the next corner, to see shops stacked floor to ceiling with probably a hundred million resistors and capacitors.

…This is Digikey gone mad.”Link.
