This tutorial is for helping you to flash firmware in your favorite ESP8266 module. First i small introduction to ESP8266: The ESP8266 is a low-cost Wi-Fi chip with full TCP/IP stack and microcontroller capability produced by Shanghai-based Chinese manufacturer, Espressif. The chip...

A tiny wireless capsule camera for medical imaging or space-constrained environments. by Ryan Bailey @ hackaday.io: Tiny, pill-sized cameras are frequently used in the medical field to visualize the gastrointestinal tract, particularly areas not readily accessible by bulkier...

TallMan's lab @ runawaybrainz.blogspot.com build a nice looking and simple analog ESR capacitor meter based on a EEVBlog forum topic. I finally got round to making my capacitor ESR tester this week after finding a nice simple 5 transistor version by EEVBlog member Jay_Diddy_B....

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...

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...

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...

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...

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...
