The PIC 40 / 28 PIN (DIP) Development / Evaluations board demonstrates the capabilities of Microchip’s 8-bit microcontrollers, specifically, 28- and 40-pin PIC16FXXX, PIC16F1XXX, and PIC18 devices. It can be used as a standalone demonstration board with a programmed part. With this board you can develop and prototype with all Microchip’s 40 & 28 PIN […]

Summary This is a description of how I designed and built my UV exposure box. After experimenting a bit with dry-laminate photo-resist and liquid UV hardened solder mask I decided to stop trying to improve my toner transfer technique and rather build a proper UV radiation unit for making printed circuit boards. I wanted it […]

Introduction This is a tutorial on building a Compost Temperature monitoring system. It details how to build a web connected wireless sensor network and shows one possible way it could be constructed. A Medium level of knowledge and skills are required. Basic knowledge of soldering and breadboarding will be very useful. I will assume that […]

A alimentação é feita por 2 pilhas AAA de 1.2V ( recarregáveis ). A escolha para se usar apenas 2 pilhas AAA é principalmente reduzir ao máximo o peso a transportar pelo helicoptero. Uma vez que 2 pilhas recarregaveis AAA só fornecem 2.4V e é necessário pelo menos 5V para atingir os níveis TTL na […]

This instructable is about how to use such a device to build a low cost light source, suitable for exposing the various UV sensitive materials encountered in printed circuit board production, like dry film photoresist and UV curable soldermask. As well as being very low cost (around $20 for all required materials), this build addresses […]

World’s first consumer IMU to provide pitch, roll, and yaw specifications, includes proprietary AttitudeEngine motion processor for longer battery life, simpler adoption and enhanced user experience SAN JOSE, Calif. – June 16, 2015 – Fairchild (NASDAQ: FCS), a leading supplier of high-performance semiconductor solutions, today launched the FIS1100 6-axis MEMS Inertial Measurement Unit (IMU), the […]

PORTLAND, Ore. — In its rush to get to market “while the iron is hot,” Vesper Technologies Inc. (Boston) has announced what it still claims is the industry’s highest signal-to-ratio (SNR) for a high-definition (HD) microelectromechanical system (MEMS) microphone, even though it is scaled back to 68dB rather than the astounding 70dB SNR MEMS mic […]

O circuito não necessita de muitos componentes…basta um microcontrolador, um receptor de infravermelhos e alguns leds para indicarem o nível de dados recebidos pelo comando. Funciona com qualquer comando desde que seja infra-vermelhos. O microcontrolador que usei foi o 12F683 da Microchip em formato SOIC. Apenas precisa de 2 pilhas AAA e consome apenas 0.8mhA […]
