Build Your Own Cheap Antenna Analyser
https://www.electronics-lab.com/build-cheap-antenna-analyser/
Ham radio is the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, etc. Developing a ham radio project may requires using an antenna analyser, a device that is used for measuring input frequency and impedance. There are many types of antenna analysers such as Anritsu VNA Master, RigExpert, […]
Recover Bricked ATtiny Using Arduino as high voltage programmer
https://www.electronics-lab.com/recover-bricked-attiny-using-arduino-as-high-voltage-programmer/
Hi! Today I’ll explain you how to recover your bricked ATtiny microcontroller using your Arduino board. ATtinys are very popular due to their small form factor yet very powerful. While working with them you may accidentally brick the ATtiny. As arduino is extremely popular and really easy to use, I guess you have one or […]
Program AVR Using Arduino the easy way
https://www.electronics-lab.com/program-avr-using-arduino-easy-way/
rik @ riktronics.wordpress.com show us how to program AVR microcontrollers using an Arduino board. Advanced hobbyists like me (and you, of course 😉) love to play with microcontroller. And the most famous microcontrollers for beginners are AVR series from Atmel™. Almost all beginners in microcontroller-world have their Arduino boards lying on work table. Because it is […]

Sonicare toothbrush teardown: microcontroller, H bridge, and inductive charging
https://www.electronics-lab.com/sonicare-toothbrush-teardown-microcontroller-h-bridge-inductive-charging/
Ken Shirriff did a teardown of a Sonicare electric toothbrush: The photos below show the top and bottom of the toothbrush internals. I expected to find a simple, low-cost mechanism, so I was surprised at how much complexity there was inside. The vibration mechanism (right) is built from multiple metal and plastic parts screwed together, requiring […]
Adding ADC to Microcontrollers without ADC
https://www.electronics-lab.com/adding-adc-to-microcontrollers-without-adc/
Scott @ swharden.com show us how to interface an analog signal to a microcontroller that doesn’t have an ADC. I recently had the need to carefully measure a voltage with a microcontroller which lacks an analog-to-digital converter (ADC), and I hacked together a quick and dirty method to do just this using a comparator, two […]
