PORTLAND, Ore.–Now before you get all excited by the headline, which is not click-bait according to the researchers, a new kind of nanoscale rectenna (half antenna and half rectifier) can convert solar and infrared into electricity, plus be tuned to nearly any other frequency as a detector. The invention was made at Georgia Tech (Atlanta) […]

Many of you may have seen the Adafruit PCB ruler (also used by the awesome Voltera). The design was actually adapted from my own design back in University! To improve on the original idea, I have created a reference business card. Here is a computer render of the design: I wanted to show every common

Three major power supply (Figure 1) architectures are defined for any engineer: 1.Linear Regulators. 2.Pulse width modulated switching (PWM). 3.High resonant technology switching. Some important parameters can described in the followig texts: Inputs: Vin(low), Vin(high) – minimum and maximum allowed input voltages, hence input voltage range. Iin(max) – maximum average input current. Outputs: Vout(min), Vout(max)

Durante as oficinas semanais de IoT no LHC, vimos que algumas placas de desenvolvimento utilizando o ESP8266 estavam surgindo, como a nodeMCU e o ESP-201, porém resolvemos criar a nossa própria placa, atendendo as nossas necessidades. Surgiu então o nodeLHC! A principal razão para a criação da placa, foi que a maioria das pessoas que

Modul USM-MEMS-VOC is based on the innovative and highly stable TGS 8100 MEMS semiconductor sensor TGS8100 from Figaro. In the presence of detectable gas, sensor resistance decreases depending on gas concentration in the air. New technology allows very rapid response to gas concentration change. The USM-MEMS-VOC reacts within 8 seconds. The module evaluates ratio

anufactured using specialized micromachining processes, while the IC interfaces are developed using CMOS technology that allows the design of a dedicated circuit which is trimmed to better match the characteristics of the sensing element. The LSM6DS3H has a full-scale acceleration range of ±2/±4/±8/±16 g and an angular rate range of ±125/±245/±500/±1000/±2000 dps. High robustness to

For my monthly maker column in Dutch newspaper “De Volkskrant”, I made a coolbox in which you can control the temperature in three separate compartments to keep craft beer at just the right temperature. The contraption I build uses three Peltier-elements to cool, an old desktop computers power source, an LCD to show both the

The controller will rotate your GoPro over a set angle for a set duration or will rotate you GoPro for a full rotation for a set duration. This project is based on the original instructable by Tyler Winegarner See instructable here and also from Mark Wheeler’s version of Tyler Winegarner’s instructable See Mark Wheeler’s instructable

The LEDs (Light Emitting Diode) are diodes whose basic characteristic is the ability to emit light when they are passed through a current that flows from P to N region. At each recombination between the charge carriers (electrons and holes), on PN junction region, a photo emission is generated, and the total quantity of emitted
