Reflash Arduino UNO ATMEGA16U2

In case you've bricked the UNO bootloader or even the USB bootloader in the ATMEGA16U2, this may help ...

IoT Powersensor #2

For the main power distribution in my house, I also build a powersensor. The basic idea is the same as for this sensor. But the electric meter is already build into the distribution cabinet, so this power meter uses the so-called S0 bus of the power meter inside the cabinet.DSCF4078

IoT Powersensor #1

This is my first power/voltage sensor I've build. It is based on an commercially available powermeter from B+G E-Tech. You can find them on eBay or their website. It provides a 90ms pulse for each Wh flown through it.6Q7A7842

The line voltage is measured using a simple transformer and a circuit based on the schematic from OpenEnergyMonitor. The software to measure the line voltage is also from OpenEnergyMonitor embedded into my sensor framework.

Arduino Library for AD7887

Based on the code  from Makis, SV1AFN I have created a small library to access the AD7887 ADC converter. The library is pretty simple to use.

IoT System management

My MQTT server also has some basic systems management capabilities - means the MQTT server can emit the following data to the MQTT broker:

  • CPU temperature
  • Power supply temperature
  • Average CPU load
  • Uptime of server

IoT MQTT Infrastructure

Since the beginning of my home automation project I made several tests to choose the right platform and right controller. I've done test with various sensor technologies etc. etc.
Most of the articels can be found in the Arduino category.

One decision was, that my webhost should be the main datastore for all data measured. With this decision, I've started to build a data collection and distribution infrastructure. The complete setup consists of two major components:

  • The home infrastructure
  • The internet infrastructure

These components are detailed further down the page.

Detailed measurement on audio CW-filter

Here I've build an audio CW-filter based on the circuit from NM0S/4SQRP.

This filter works pretty well. I've done some audio analysis using a cheap soundcard from BEHRINGER and the shareware application AUDIOTESTER.

Rotator control and the NodeMCU - a proof of concept

Basics

Inspired from the work of EA4TX and K3NG I decided to check, whether the ESP8266 based NodeMCU 1.0 (ESP-12E) is usable as a simple remote IP-based rotator control. You can get the NodeMCU in a decent quality on eBay.

Idea was, to link a local emulated serial port to the NodeMCU module. The HAM Radio applications are communicating via the standard Yaesu GS232A protocol with the emulated serial port.  This emulated serial port then forwards the serial requests to the NodeMCU.

CW-Sensor-Keyer

Based on the work of John, M0UKD, I've build a small sensor-keyer. I used a surplus aluminium shelf and two aluminium stand-offs as "paddles".

See the evolution of this project here.
