App note: Solid-State Relays
Solid-state relays introduction from Vishay, (PDF) MOSFET SSRs feature an optocoupler construction, but have a pair of MOSFETs on the output instead of a phototransistor. A pair of source-coupled MOSFETs emulate an electromechanical relay by providing bidirectional switch capability...

Exploring the Transcend Wifi-SD card
James O'Neill explores a Transcend SD that he believes it's the smaller Linux server. It's actually a 16GB memory card, an ARM processor and a WIFI chip all in an SD card package. The way these cards works is different from the better known Eye-FI card. They are SERVERS : they...

Hacking the OWON SDS7102 Scope
Christer Weinigel did a teardown of OWON SDS7102 oscilloscope. He explained how its internals are connected, ported Linux to its Samsung SoC in the scope, succeeded in getting its peripherals working, and set to work programming the Xilinx FPGA that’s responsible for signal...

Inside the SDS7012 Oscilloscope: Mainboard Analysis
Christer Weinigel has been tinkering with an OWON SDS7012 o’scope, including deciphering the device’s OS and even disassembling the bootloader. Now it’s time to dive in and examine the mainboard, physically, with many of the board’s sub-circuits explained. via...

Single transistor provides short-circuit protection
Keith Szolusha@ edn.com writes: In certain dc/dc-converter applications, on-chip, cycle-by-cycle current limit may be insufficient protection to prevent a failure during a short circuit. A nonsynchronous boost converter provides a direct path from the input to the short circuit...

IoT IP camera teardown and getting root password
Jelmer @ jelmertiete.com did a teardown on a cheap IP camera and also obtained the root password of it with the goal to investigate the security of such a devices. He writes: IP Cameras have become extremely cheap in the last couple of years. Mass production made the prices of...

Teardown: Amazon Dash Button keeps you connected
Brian Dipert @ edn.com has done a teardown on Amazon's dash button and shows the parts inside. How much hardware was Amazon able to squeeze into such a diminutive bill-of-materials budget, or perhaps more accurately, how much are Amazon and its consumable-supplier partners...
