Building the Colossus LED Display
https://www.electronics-lab.com/building-the-colossus-led-display/
by Adam Haile @ maniacallabs.com: The 2014 NC Maker Faire was a huge turning point for Maniacal Labs. It was there that the idea for the AllPixel and what is now BiblioPixel got their start. It’s also where we showed off our first custom-built LED display, the 24×24 LPD8806 matrix. At nearly 24 inches square, […]
Arduino based MPPT solar charge controller
https://www.electronics-lab.com/arduino-based-mppt-solar-charge-controller/
by Abid Jamal @ electronicslovers.com: what is Mppt( Maximum power point tracking) ? “we use MPPT algorithm to get the maximum available power from the Photovoltaic module under certain conditions” How MPPT works ? Why 150W solar panel does not equal to 150 w? For example you bought a new solar panel from the market which puts […]

Teardown & Repair of a Stanford Research PS350 5000V, 25W High Voltage Power Supply
https://www.electronics-lab.com/teardown-repair-of-a-stanford-research-ps350-5000v-25w-high-voltage-power-supply/
In this episode Shahriar repairs a Stanford Research Systems Model PS350 5000V-25W High Voltage Power Supply. The unit continuously displays 2.5kV without the output being enabled and produces no output voltage. Verification of power supply voltages reveals the issue is linked to a disconnected 15V voltage regulator IC. After the repair, the output voltage is […]

Basic Types of Thyristors and Applications
https://www.electronics-lab.com/basic-types-of-thyristors-and-applications/
In this article we will discuss about the various types of thyristors. Thyristors are 2 pin to 4 pin semiconductor devices that act like switches. For example a 2 pin thyristor only conducts when the voltage across its pins exceeds the breakdown voltage of the device. For a 3 pin thyristor the current path is […]
Don’t be afraid of heatsinks modifications
https://www.electronics-lab.com/dont-be-afraid-of-heatsinks-modifications/
If you´d like to use some of standard heatsink profiles, but you need for example an extra opening, we´ll supply it to you customized according to your needs. Perhaps everyone of us is familiar with a sentence mentioned in various catalogues, á la “upon request we can supply you a customized version”. Naturally that sounds […]
How to Set Up the DHT11 Humidity Sensor on an Arduino
https://www.electronics-lab.com/how-to-set-up-the-dht11-humidity-sensor-on-an-arduino/
by circuitbasics.com: Because of their low cost and small size, DHT11 humidity and temperature sensors are perfect for lots of different DIY electronics projects. Some projects where the DHT11 would be useful include remote weather stations, home environment control systems, and agricultural/garden monitoring systems. The DHT11 is a digital sensor that lets you easily get relative […]
Signal Generation with MATLAB. Example of DTMF in telephony
https://www.electronics-lab.com/signal-generation-with-matlab-example-of-dtmf-in-telephony/
by Maurizio @ dev.emcelettronica.com: In mathematics a signal is a real function of a real variable f(t). In electronics it represents the evolution of a voltage (or a current) over the time and depends on the performances of the stage of the amplifier. Through a memory buffer, samples move to a digital-to-analog converter that produces a […]
Adding Sensors to Monitor Hive Health
https://www.electronics-lab.com/adding-sensors-to-monitor-hive-health/
by Nathan Seidle @ makezine.com: The Digital Beehive uses Wi-Fi to broadcast a beehive’s weight, humidity, temperature, and battery voltage every minute to SparkFun’s data channel service called Phant. The raw data can be seen here but you can view some prettier graphs of the data here on analog.io (sign-in required). Adding Sensors to Monitor Hive […]
