This project is about building a PC-based temperature and relative humidity logger using the chipKIT Uno32 board and the DHT11 sensor. The project setup requires no additional wires (other than the USB cable) and components; the DHT11 sensor is directly plugged into four I/O pins of the Uno32 board and the project is ready to […]

That’s where Cota by Ossia comes in. The startup is the brainchild of physicist Hatem Zeine, who decided to focus on delivering wireless power in a way that was commercially viable, both for large-scale industrial applications and for consumer use. Zeine has been hard at work developing his wireless power technology and refining its delivery

Analog-to-digital-conversion (ADC) is required in Embedded Systems to deal with various analog world parameters such as current, pressure, motion, temperature, etc. An ADC is an electronic system or a module that has analog input, reference voltage input and digital outputs. The ADC convert the analog input signal to a digital output value that represents the size of

Having obtained a reasonably reliable 10MHz lab reference (see here) I decided to calibrate my Frequency Counter only to find that the stock oscillator provided in the HP 53151A is absolutely terrible – a joke even! I looked around for an “010 High Stability Timebase Option” but they are rare — and if you can

500, 400, 300 mW are common values of coils power consumption of mid-power relays. But JV-xS settles for 200mW and operates even at 113 mW! Power consumption of for example 500 mW is low at the first sight and it may seem, that at a power consumption of other power circuitry it somehow “disappears”. Sometimes

Editor’s note: The following is a Sand 9 white paper discussing the evolution of MEMS technology in our industry as it relates to timing devices. Quartz has dominated the industry until recently. Electrostatic and piezoelectric MEMS now seriously compete to displace quartz in many applications with improved overall tolerance across all frequencies. PSRR in a

Nix is a patent pending device that allows anyone to become a color expert. Just grab Nix from your pocket, purse, or bag, touch it to an object and magically watch the exact color appear on your iPhone, Android, PC, or Mac. Once scanned, you can keep palettes of your favorite colors, match the color
