Making a Geiger counter with 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...

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...

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...

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...
