In this project I take an Arduino Mini Pro connect it to a custom made Etch A Sketch panel and use it to control a Blacknose laser cutter. The result is hours of crazy laser cutting fun, which we will be taking round most of the UK Maker Faires this year for JustAddSharks.co.uk The Etch […]

The F1950 Digital-Step-Attenuator featuring Glitch-Free™ technology improves system reliability and settling time.  It has an attenuation range of 31.75 dB with excellent accuracy and very low distortion. Features Glitch-Free™, < 0.6 dB transient overshoot 150 MHz to 4000 MHz frequency range Spurious Free Design 3V to 5V supply Attenuation Error < 0.3 dB @ 2 GHz Low Insertion Loss < 1.3 […]

Intel announced its 4004 processor and its chipset through an ad in Electronic News on November 15, 1971, making them the first complete CPU on one chip and the first commercially available microprocessor. The building-block 4004 CPU held 2300 transistors. The microprocessor, the size of a little fingernail, delivered the same computing power as the […]

Age Group: 13 – 18 My experimental rover that I built from a Roll-A-Way alarm clock that was on clearance for $5. It can be controlled via the numeric section of a keyboard when the serial port is connected to a computer or a Wii Nunchuck attached directly to it, using either the joystick portion, […]

¿What questions need to be resolved? ¿How to recognize the origin of the table? — The table is the piece of the machine where you place your board, and is critical for the pick and place operation. I’ve thinking in a limit switch system. Will be the use of the “tglue layer” of the Eagle […]

I got my first taste of programming with RCX Code and an old Mindstorms RCX 1.0, so maybe it’s nostalgia speaking, but I really admire visual programming languages for their ability to introduce younger folks to programming. With color coded operators, geometrically shaped data types, and no semicolons (!), visual languages have a unique ability […]

Winter just arrived. The enemy of all batteries. Last year this was the season the auxiliary battery of my T3 VW camper bus bit the dust. This likely happened because I neglected to take care of it over the winter months during which the bus is typically parked in my garage. When the auxiliary battery […]

DESIGN OF A SMALL SCALE SMART HOME SYSTEM Gabriel Johnson and Chance Kelsoe INTRODUCTION Design of a smart home system with a LabView/Arduino interface In this project we made use of an Arduino Duemilanove and LabView to design an easy to use graphical interface to represent a control environment that every home owner could use. HIGH […]

Ever come home in the rain to find the door locked and your keys elsewhere? No? Lucky you then! For those who have had such an experience or never wish to, this project will let you open your garage door with nay but a smartphone/tablet/laptop/WiFi-thing and your super secret password! After all, who leaves their […]

Contributed by Publitek European Editors 10/15/2013 Power MOSFETs have become very popular in power electronics designs because of their low capacitance and good high-frequency switching characteristics. They have reached into many applications and are helping to open up new markets in applications, from hybrid and electric vehicles through solar power to extreme-environment exploration. The unifying […]
