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 […]

Since when white light emitting high brightness LED are available, the handover from traditional lighting bulbs to the solid-state lighting has become irreversible: LEDs have an efficiency (expressed in lumens/watt) higher than that of almost all the traditional lamps (except, at the moment, the large sodium vapor lamps used for street lighting, unusable in closed […]

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 is a just-for-fun project I did in the Digilent MakerSpace. Usually whenever I play board games I use a dice-rolling smartphone app since dice are so easy to lose. I thought I would try making my own hardware version though. It turned out really well and was a lot of fun. In this Instructable […]

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 […]

This BLE smart car is completed based on our latest design bluetooth 4.0 chiped- BLEDuino, L298 Motor shield, smart car body. The smart car production is simple, as DIY enthusiasts can complete their own smart car only in the form of building blocks, and the operation is also very simple, just controlling it via bluetooth […]

Hello Everybody , the goal of this instructables is to learn how to do a simple locker for your room, or anything which need to be safe. I’ve made it on a non-soldering card but there is the PCB if you want to make it ! Here is the list of differents components that we […]

[advanced_iframe securitykey=”7053122eaa09ce46830dfb8aaeae454056003ad0″]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 […]

In this episode Shahriar explores the world of Delta-Sigma modulators with emphasis on a Delta-Sigma Analog to Digital Converter (ADC). The basic concepts of analog to digital conversion is presented, particularly with respect to quantization noise spectral shape and power density. Next, oversampling ADCs are presented to demonstrate the possibility of increasing SQNR (ENOB) through […]
