RF is just way too cool not to use in your designs. But if you’re a newbie like me it is difficult to successfully build solid RF transmitters and receivers. When I started out I didn’t realize that the larger breadboard I was working off of was causing a lot of the signal deviance because […]

The Si2178/58/48/38/28 is Silicon Labs’ fourth-generation hybrid TV tuner family supporting all worldwide terrestrial and cable TV standards. Requiring no external balun, SAW filters, wirewound inductors or LNAs, the Si21x8 offers the lowest-cost BOM for analog, digital and hybrid TV tuners, with or without a demodulator. Also included are an integrated power-on reset circuit and an option […]

Digital Humidity Sensor SHTW2 (WLCSP) Simplicity Meets Proven Performance The SHTW2 is Sensirion’s 2nd generation WLCSP (wafer-level chip-scale package) humidity sensor, offering a complete digital humidity and temperature sensor system in a package so tiny that it fits into virtually any application. The SHTW2 comes in a flip chip package, which is an established technology […]

Wireless Fidelity or “Wi-Fi” plays a major role in today’s communications by enabling constant connection in the 2.4 GHz and 5 GHz bands and broadband Internet access for users with laptops or devices equipped with wireless network interface while roaming within the range of fixed access points (AP) or a public hotspot. The BFx840xESD product […]

The data logger consists of a simple op-amp amplifier circuit that amplifies the signal and sends it to be digitized by a PIC16F688 microcontroller, serialized, and sent to the computer’s serial port via a MAX232 serial driver: I guess you are already wondering about some of the unusual arrangmenents in the analog part in the […]

We launched the Common Parts Library (CPL) in September 2014 to make part selection easier and to speed up the PCB design and manufacturing process. Since our launch, we have iterated several times based on feedback from CPL users. In August 2015, we introduced the Common Parts Library for Prototyping which was designed to complement […]

Cheap PIC controlled Helmet Camera using Sony LANC (Good for Extreme Sports) This Instructable will show you how to make a cheap Helmet Camera which can be controlled via a remote so your main camera can stay safely in your ruck sack. The controller can be attatched to one of the shoulder straps of you […]

The Avago Technologies MGA-43428 is a fully matched power amplifier for use in the 851-894 MHz band.

Features [-] High Gain: 34dB High Linearity performance: Max -50dBc ACLR at 27.2dBm linear output power Good efficiency […]

The new digital SHT3x humidity sensor series takes sensor technology to a new level. As the successor of the SHT2x series it is determined to set the next industry standard in humidity sensing. The SHT3x humidity sensor series consists of a low-cost version with the SHT30 humidity sensor, a standard version with the SHT31 humidity sensor, […]

Since we now have a beautiful robotic chassis, we’re ready to continue our Building A Robot series, and get serious with some motor control. This second part of building a robot is perhaps the most crucial as it will define what type of control we will have over the motors. Ideally, we want a simple […]
