That moment you take your eyes off the TV remote for just a second, because of which it falls into the hands of your annoying sibling. Yes, fighting for control over the TV is a daily struggle for many. But the TV Remote Jammer shown in this Instructable, will make everyone else stop dead in […]
INTRODUCTION BridgeDuino (R 0.11) is a Swiss army knife PCB for rapid networking of inexpensive wireless communication modules. Breadboards are super for one-off experiments. But after prototyping half a dozen wireless prototypes involving more than just two Arduinos, the wiring mistakes and associated debugging grew more time consuming. BridgeDuino facilitates rapid multi-node prototyping & testing
VHF Aircraft radio communications receiver This is simple radio receiver project which is capable to receive aviation radio voice signals which are transmit between 118MHz to 138MHz in AM (A3E). We got initial idea of this project by reading Sverre Holm’s (LA3ZA) article about “cheap VHF receiver project“. Like LA3ZA’s original article this project is
Even a simple, well-designed tool can help significantly – we´ll introduce to you some of them … Sometimes, only a little bit is necessary to make our work more happy – a good ergonomic chair, workbench in a suitable height, good lighting … and last but not least also a good screwdriver, magnifying lens, tweezers,

This design features a fourth generation programmable femtoclock that provides reference frequencies to replace crystals and SAW oscillators in high-performance applications. It is programmable through I2C interface. It has four selectable LVPECL or LVDS via I2C while its FemtoClock NG VCO ranges between 1.9GHz to 2.55GHz. It also meets the standard interface requirements of PCI

New 1,4“ round display module from company 4D Systems with a round pixel placing is able to truly display various analog variables. The evolution sometimes shows, that not everything “new” is automatically better than something „well-proven“. One of examples was also a „boom“ of digital panel meters, when it seemed for a while, that the
This reference design features the 8T49NS010 integrated circuit that functions as a clock synthesizer with a built-in fanout buffer and divider. By using an external clock source or a crystal, the 8T49NS010 can generate high performance timing geared towards the communications and datacom markets, especially for applications demanding extremely low phase noise jitter, such as

Problem: with my previous work I can take a PCB x-ray at fairly high resolution (see bond wires like above) but the field of view is pretty small. The above x-ray doesn’t even cover an entire PDIP-40. How can I see the entire PCB?Linear stageLinear stages are great for this sort of project. As I’m
