The DMM (digital multimeter) is a basic measurement tool for nearly every electrical engineer and many other engineers. With the push to constantly improve power efficiency in electronic designs comes a need to not only measure voltage and current, but to dynamically see them as well. Keithey’s DMM7510 combines a 7½-digit DMM with an 18-bit, […]
DMM provides numerical and graphical displays Continue Reading
Since now on, it will be easy to provide your Arduino with Internet connectivity by using this shield. The shield sports a TCP/IP stack manager, in order to free up the Arduino from some basic tasks. It’s also essential to equip the board with a library, that communicates with the TCP/IP manager and makes it
A new Wi-Fi Shield to connect your Arduino to the Internet Continue Reading
Another Robot, another App(lication) of Arduino. The user [shreks7] built up an Android App for controlling the robot wirelessly and stream live video off an android phone placed on the robot. The robot has an inbuilt wireless router and two brush-less DC motors and runs on a power source of 26-30V(depends on the requirement) power supply.
In this Instructable, we will be building a compass using the TinyShield Compass as well as the Circle Edge Led shield. Before starting, the proper drivers must be installed to detect the COM ports. These drivers must be installed before downloading any codes from the codebender plugin. The drivers needed can be found here. Lucky
Ladyada and pt had an old NeXT keyboard with a strong desire to get it running on a modern computer. These keyboards are durable, super clicky, and very satisfying to use! However, they are very old designs, specifically made for NeXT hardware, pre-ADB and pre-USB! That means you can’t just plug the keyboard into an ADB or
Pinoco was hit with the holiday rush, so it took a few extra weeks to get my new batch of laser cut acrylic. I nailed it this time. Right away I could tell the engraving was perfect. I even spaced out the holes for the speaker just a hair. The holes on the last one
Numitrons are neat display devices similar to nixie tubes but designed for much lower voltages. Numitrons are basically incandescent displays in which filaments create the segments. They have a retro look that I liked so much. I bought 6x IV-9 Russian Numitrons in eBay, they were about 3$ each, they’re pretty cheap! At that time
Swiss scientists have created the first semiconductor laser consisting solely of elements of main group IV (the carbon group) on the periodic table. Simply, this means that the new device is directly compatible with other elements in that group – such as silicon, carbon, and lead – and so can be directly incorporated in a
First germanium-tin semiconductor laser directly compatible with silicon chips Continue Reading
The world’s first 100MS/s open source oscilloscope for iPad, Android and PC. A must-have for every Arduino and Raspberry Pi developer! SmartScope The SmartScope combines 3 high-end instruments into 1 mobile, smart device. Accessible previously only to high-tech labs, the SmartScope allows everyone to own a personal lab! Starring a dual-channel 100MS/s oscilloscope, the SmartScope
In embedded systems, oftentimes it is needed to generate analog outputs from a microcontroller. Examples of such include, generating audio tones, voice, music, smooth continuous waveforms, function generators, voltage reference generators, etc. Traditionally in such cases the most common techniques applied are based on Pulse Width Modulation (PWM), resistor networks and external Digital-to-Analog Converter (DAC)
