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...

Wireless Weather Station using Arduino Due, DHT22 sensor and NRF24L01+
educ8s.tv uploaded a new project on youtube. In this video we build a Wireless Weather Station using the fast and powerful 32bit Arduino Due board. We measure the temperature and the humidity with a couple of DHT22 sensors and we communicate with the remote sensor using the 2.4GHz...

Dynamic-load circuit determines a battery’s internal resistance
by Jim Williams @ end.com The simplest model of a battery comprises an ideal voltage source that connects in series with a resistance whose value—often a few milliohms—depends on the battery's electrochemical condition and construction. If you attempt to use an ordinary ac...

Consolite – a Tiny Game Console on an FPGA
Robert Fotino has design a video game system on a FPGA. He writes: For my latest project, I am diving back into Verilog to create the hardware side of Consolite. For those who don't know, Consolite is the name I've given to my design of a tiny hobbyist game console and associated...

Butchered USB TTL Serial Adaptor
Aaron Brady writes: We popped open the case, and there were two main ICs, a Prolific 2303 (the USB to Serial IC) and a ADM3251E (the RS232 line level convertor). I tried to desolder this with no success, but Bas stepped in, cut the leads with a craft knife and ran the iron over the...
