If you’re like me, you don like buying stuff that’s ready-to-go, but rather build one yourself. We usually spend more money, but it’s way more satisfying I really didn’t want to buy an overly expensive 32ch FPV LCD receiver, so I made my own DIY 32ch FPV 5.8ghz LCD, that is compatible with EVERY transmitter on […]

Linear Technology has put the whole of a supercapacitor power back-up system on one chip. Rated at 2A, it will back-up a voltage rail (Vsys) between 1.71 and 5.25V. Key to the chip, called LTC3110, is a 1.2MHz four-switch bi-directional dc-dc converter that both charges the capacitor and can also extract almost all of the

The module based on DS1307, The DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I²C, bidirectional bus. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is
ulibSD It’s a library for use SD cards in SPI mode with uControllers, entirely written in C. This library can work with SD cards and also has the possibility to emulate the behavior in a PC file (GNU/Linux) using the macro _M_IX86. It’s for debugging purposes. The data transfer is oriented to 512 byte size,

The Omron RS8 met several of our design requirements, small, battery operated, quiet and entirely wrist mounted. So no heavy base unit. With the initial attack vector expected to be the NFC interface the case was opened and warranty voided. Thankfully the PCB was not too complicated, although populated on both sides the dual layer

Recently I’ve found this piece of electronic on the dumpster, it was looking interesting – compact case with battery holder, LCD display, temperature and humidity sensor. It has also radio transmitter, but I’m not interested in it since I don’t have the receiver station. I decided to bring it back to life.It seems that was

Altera has returned to its roots with its latest Stratix 10 FPGA family. The performance figures of this device are certainly impressive. It reminds me of the days when FPGAs were only ranked by their gate count process technology and clock speed. This was before suppliers felt they had to re-style FPGAs as configurable processors.

Samsung’s decision to use more ARM processor cores in its smartphones and tablets is not surprising. But these are not Cortex-A series processors they are Mali graphics processing units (GPUs). ARM rival Imagination has the GPU of choice for the mobile market. Apple, Samsung, Motorola, Nokia all use PowerVR graphic processors developed by Imagination. As

Quad Flatpack No leads (QFN) packages offer at least one advantage over Ball Grid Array (BGA) packages: because the electrical connections are partly made via solder lands on the side of the component visual inspection of solder joints and repairing them is easier. Thermally enhancing a package for power applications can be done with a
