Teardown of a fake USB flash drive from India and a USB charger from China. A look at the new xQFP protoboard v2 PCB, and a new filing system for free PCBs. We’ve been doing workshop videos for more than a year now, so we look back on the evolution of the weekly updates.
While on our Global Geek Tour of India we scored a fake 32GB flash drive. We hoped it was one of those smart fakes that have only 1GB of memory, but simulate a 32GB drive by correctly recording the full 32GB file indexing. It turns out our flash drive was just a USB cable jack stuffed into a flash drive case.
Disillusioned by our flash drive experience we expected to be similarly burned by the USB charger we picked up for $0.25 during our latest Shenzhen visit. The charger is small, very light, and the USB jack sits a little crooked inside. We were pleasantly surprised to find two PCBs, a few caps, and a coil inside.
Version 2 of the QFP protoboards just arrived in the workshop. We moved the PCB to the Sick of Beige standard, and extended the IC pin footprints to make it easier to solder. This time around we placed 2 different pitch QFP footprints on each side of the board. These boards will go into production when the current batch of QFP protoboards is depleted at Seeed.
The previous versions of the QFP protoboards are available for $10.
We’ve been doing Workshop Videos for a year now, and we take a look back at the evolution of the update videos. At first we had floating hands explaining electronics in a poorly lighted workshop. As the time progressed we got more cameras for better angles, much better lighting, dedicated microphones, and finally a large workshop.
