https://www.electronics-lab.com/beginner-friendly-two-sided-development-board/
MikroElektronika, the microcontroller development boards and accessory boards manufacturer, introduced a new development board for beginners and non-experts called Flip & Click. Flip & Click is a rapid prototyping tool that is an Arduino Due on one side, and four mikroBUS™ sockets on the other side. The first side, the blue side, is Arduino Due […]
Glucose Wearable Biosensor
https://www.electronics-lab.com/glucose-wearable-biosensor/
Biosensors for consumer wearable devices is a new trend as it facilitates multiplexed physiological monitoring for quantitative assessment of body functions. Highly functional wearable biosensors that can also provide meaningful diagnostics to guide therapeutics would be extremely valuable to end-user consumers or health-professionals. Researchers at The University of Texas at Dallas developed a wearable device […]

https://www.electronics-lab.com/14-5-purpose-switched-mode-power-supply/
Switching technology devices and integrated circuits are growing fast providing solutions that obtain power for different kind of circuits and devices, and they are proposed in different variations. A useful little known kind which is suitable for mixed supply systems is called SEPIC,single-ended primary-inductor converter. Torpedo is a switched-mode power supply with a SEPIC configuration […]
Making a Geiger counter with 555 timer IC
https://www.electronics-lab.com/making-geiger-counter-555-timer-ic/
Radioactive particles are found abundantly in nature. Whether they come from space or generated on Earth (radioactive waste, medical X-rays, etc), they are high-energy particles resulting from radioactive decays. The three major types of radioactive particles are named after the first three letters of the Greek alphabet: α (alpha are helium nuclei), β (beta are […]
Tiny OLED PC Performance Monitor
https://www.electronics-lab.com/tiny-oled-pc-performance-monitor/
Rupert Hirst build a tiny OLED PC performance monitor based on Psyrax’s serial monitor. The display monitors CPU and GPU temperature and activity etc. He writes: After a recent purchase of a Nvidia GTX1080 graphics card, 4k monitor plus Doom(2016), I thought it would be great to see some external telemetry… from my exorbitant purchase. Then, […]
MCU based LED VU Meter
https://www.electronics-lab.com/mcu-based-led-vu-meter/
dannyelectronics.wordpress.com discuss about how to build a mcu based LED vu meter and provides sample code. From time to time, I see people trying to build an audio VU meter. In the analog era, that’s typically done with a voltage divider + a series of comparators; or using chips like LM3914/3915. Those chips are harder […]
RC Signal Monitor Using Bargraph & RC Switch using Relay
https://www.electronics-lab.com/rc-signal-monitor-using-bargraph-rc-switch-using-relay/
The versatile Bar-Graph SMD components based R/C monitor & R/C switch is a great tool for R/C hobbyist R/C modeller and DIY robotics. Tiny Bar-Graph displays provide a Red color bright, easy to read display of Radio Control (R/C) signal from 1mS to 2mS. The Barograph RC Signal reader is based on PIC16F886 microcontroller. This […]
ESP8266 16MB Flash Handling
https://www.electronics-lab.com/esp8266-16mb-flash-handling/
Piers Finlayson shares his adventures in programming the ESP8266 to access 16MB flash: To put this in context, the original ESP8266 modules (such as the ESP-01) offered 512KB of flash, with the more recent ones (ESP-07) 1MB and then 4MB. The maximum addressable flash memory of the ESP8266 is 16MB according to the datasheet. (The […]
MPPT solar charger
https://www.electronics-lab.com/mppt-solar-charger/
Lukas Fässler show us his progress on the MPPT solar charger: One of my main goals with this design is to achieve very low standby current, somewhere in the tens of microamps. The basis for this is a low-power buck on the basis of a Texas TPS62120 where the microcontroller can switch the output voltage […]
RFID Tutorial with an Arduino Uno and an OLED display
https://www.electronics-lab.com/rfid-tutorial-arduino-uno-oled-display/
educ8s.tv uploaded a new video on a RFID Arduino Tutorial: Today we are going to build a very interesting project. For the first time we are going to use RFID tags with Arduino. I have built a simple project which reads the Unique ID (UID) of each RFID tag we place close to the reader […]
