Knowing how your antennas work or build and optimize our antenna is very rewarding. Unfortunately, it needs knowhow and some costly equipment to do that. Today we will change that, and I show you an affordable new tool which enables these tasks. This small device was one of my best investments I made so far. At the end - You know how to build and optimize a LoRa ground plane antenna - You will know How to tune a commercially available antenna - You will get a little theory behind it, as usual And we will have a close look at this small gadget from China and compare it with a professional tester Links: N1201A Antenna Tester: http://s.click.aliexpress.com/e/Nhr3Xedw Calibration Set: http://s.click.aliexpress.com/e/q3VbiQ7 or http://s.click.aliexpress.com/e/VJeqJY7 (not tested) N2201SS (2 ports): http://s.click.aliexpress.com/e/CHDgGnr2 Ground Plane calculator: http://www.buxcomm.com/ground_plane_calculator.htm SMA connector for Antenna: http://s.click.aliexpress.com/e/RBAYzbU What's inside the N1201SA: https://notes.superlogical.ch/?p=89 Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot My Patreon Page: https://www.patreon.com/AndreasSpiess If you want to support the channel, please use the links below to start your shopping.

The ESP32 is a beast, with some “secrets.” Today we will look at its pins and create a “Priority” pin list, which saves you a lot of time and hassle. In this video: - We will get an overview of all pins of the ESP32 - Learn which pins have particular purposes and therefore have to be treated with care - Learn the real universally usable pins - Create a strategy on how to use the many pins for our projects - And do some programming examples I am a proud Patreon of @GreatScott! , @ElectroBOOM , @Electronoobs , @EEVblog , and others No Docker, No Microsoft Teams, Zoom, no IKEA Links: My favorite ESP32 development board+extension: https://s.click.aliexpress.com/e/_A2ZMXy My favorite "project board": https://s.click.aliexpress.com/e/_A1IEdu or https://bit.ly/2ohsawD or https://amzn.to/3q38841 Excel Sheet: https://drive.google.com/file/d/1gbKM7DA7PI7s1-ne_VomcjOrb0bE2TPZ/view?usp=sharing The links above usually are affiliate links which support the channel (no additional cost for you).

In this video I show how to change flash memory chips in ESP8266 ESP-01 and ESP-07 modules. I show how you can check memory size with your Arduino IDE and use ESP-01 now for upload over the air.

Viewers often ask me how I print cases for my projects. In this video, I will show you how you can print your own boxes with a simple and free of charge method based on what I call a “Configurable Base Box.” As usual, we will focus on how you can get things done. It will not at all be a CAD tool training video. I am a proud Patreon of @GreatScott!, @ElectroBOOM , @Electronoobs , @EEVblog , and others. No Docker, No Microsoft Teams, Zoom In this video we will: - Find the information to install Fusion360 and get a free of charge license for Makers - Use my adjustable “base box” as a head-start - Adjust this box to the right size and add some holes for power, LEDs, or other stuff - I will also show you a trick on how I create perfect 3D printed holes - and how I attach PCBs like an Arduino inside the box Links: Free Maker license for fusion360: https://www.autodesk.com/campaigns/fusion-360-for-hobbyists File with box template: https://github.com/SensorsIot/Project-Box-Templates Adafruit video: https://www.youtube.com/watch?v=VVmOtM60VWw Prying Tool: http://s.click.aliexpress.com/e/8K0Pt6s Reamer: https://s.click.aliexpress.com/e/_9jZf1R or http://bit.ly/2HMfhzT Step-Drill: http://s.click.aliexpress.com/e/bDtwC7Vm or http://bit.ly/2GRYxK7 or https://amzn.to/3heR88H Arduino Mega: http://s.click.aliexpress.com/e/b2BFQmZ6 or https://amzn.to/3ylXFny The links above usually are affiliate links that support the channel (no additional cost for you).
