Sensor Modules It’s been a long time since I’ve post a new hobby project of mine! I decided that is time to upload a new one! Like my Sensor Stick module this project will be about sensors as well. You can find multiple modules out there with various sensing ICs that almost all of them […]

Voltcraft sets of measuring leads provide several reasons why to choose right them. Maybe we even don´t realize in a common praxis, how important role is played by measuring leads of a measuring device, the most often multimeter. Firstly, they´re “responsible” for a good transfer of a signal to a measuring device and at the […]

Take it wherever you want. The Freaks3D weighs 2.945kg and battery compatible. It is completely portable. Small enough to blend in with any table but large enough to unleash your creativity. Less is more. Simplified extruded-aluminum beams to ensure sturdy and high-quality performance. The Freaks3D employs v-slot slider system to provide precise seamless positioning. Quality […]

This is the first hack we made using the new IoT Kit Wi-Fi! We know you guys like to eat during night (the best time for programming and hacking) but this is a really unhealthy habit and we want you fit and healthy! How it works The alarm for your fridge activates at a certain time and […]

In the last period we can see, that producers go on the way of processors combined with interface converters grouped into a single chip. Company Wiznet also goes this way.   At the end of May 2015, Wiznet launched on the market the new W7500, combining the HW TCP/IP interface converter W5x00 with an MCU. […]

I love LED chasers. A bunch of LEDs neatly turning on and off on a precise timing – lights running one way, then the other way… It’s relaxing, soothing, and hypnotic. There are so many LED chaser/scanner/sequencer circuits out there, some are made with discreet transistors, some based on logic ICs, and more and more […]

Noise on a signal creates a triggering challenge for test equipment, especially oscilloscopes. Becuase the instrument itself also contributes noise, small signals in the millivolt range need proper instrument settings prevent noise from overwhelming the signal of interest. Even with larger-ampltude signals, noise can create a condition where a stable trigger is difficult to achieve. […]

It is often said that “the devil is in the details.” All too often those details are hidden deep within a datasheet where you can easily overlook them. When a datasheet reference circuit is copied into a product, the designer must still be fully aware of how the circuit functions and anticipate unexpected problems that […]

New aerial from 2J will surely not surprise you by its size, however features of the antenna are worth noticing. 2JW035 antenna measures only 52,5mm and is intended for WiFi and Bluetooth devices in 2.4 a 5GHz bands. The gain is 5dBi and the VSWR value is below 2.6:1. A big advantage of this antenna […]
