TCL to launch motion-controlled Android TV first in China

... the United States, Europe, or Japan by storm, TCL is eagerly positioning itself to mine the Chinese smart TV market. TCL is demonstrating its second-to-none speed in becoming a leading vendor of smart TVs with advanced features. Keys to that speed are licensable software and readily available smart TV SOCs. TCL pulled it off first by partnering with Hillcrest, and second, leveraging an Android TV SOC developed...

Use a transistor as a heater

... power during initial power-up; if you set it for maximum power, you could apply 24V to Q2’s gate-to-source voltage, which is rated for a maximum of only 20V. You can extend the temperature range by changing the voltage divider comprising R1, R2, and VR1. The design includes a safety cutoff circuit (not shown) in case the temperature gets too high.Various other options are also possible applications...

Microchip PIC16F(LF)178X brings integrated analog and digital to 8-bit microcontrollers

...-mode controller (PSMC). The addition of a PSMC, in this case a 16-bit PWM operating at 64 MHz, helps with closed-loop control in power supplies and lighting, and the LF version features the company's extreme low-power technology for active and sleep currents of 32 µA/MHz and 50 nA, respectively. The combination of PSMC and low power makes the device suitable for its target applications, including LEDs, battery management, digital power supplies, and motor control. The devices operate at speeds as high as 32 MHz and include an internal oscillator. They come with 3.5 to 14 kbytes of flash, 128 to 512 bytes of RAM, and 256...
