Kappelt gBridge allows you to control almost any smart home device with Google Assistant. It receives smart home commands from Google Assistant (on platforms like Google Home) and transmits them accordingly to an MQTT broker. Got curious? Have a look: https://about.gbridge.kappelt.net or read the documentation.

Soon, there will be a huge update for the stable version of the Trådfri module. Your action is required after installing the upcoming update. For instance, you have to install Java on your system. Libcoap and the software coap-client isn’t necessary anymore.
The module is constantly evolving. There will be a new version in the future, its main change is a new implementation of the CoAP protocol. This change enables new features, like the real-time updating of device readings. This post is intended for users, that want to try the new beta version.
This is a small extension module for the FHEM Home-Control software. It enables connectivity to an IKEA Trådfri gateway. Continue reading “IKEA Trådfri module for FHEM”

I’m one of the lucky guys, who is able to go to the embedded world 2016 Exhibition&Conference (just two of the three days) in Nuremberg.
There were some quite impressive presentations and demonstrations, I got some news from the embedded world and enjoyed the visit. Of course, there is a much more interesting part for makers like me: the free development kits that you’ll get. Some manufacturers basically throw them after you. I’ll show you some I’ve got:
Please excuse the ugly pictures, I’ve taken those with my smartphone in a train. I’ll replace them later with better ones.
CY8CKIT-043 – Cypress PSoC 4 M
So, it is basically a small development board from Cypress, featuring their PSoC 4 processors. A programmer and debugger is also included onboard. If you want to learn more about it, you can visit the Cypress page. If you haven’t been to the embedde world, you can buy one for just 10$.
There is a PSoC 4200M Cortex-M0 microcontroller. But there is something special about it: you can reconfigure the hardware with simple drag-and-drop actions in their PSoC-Creator IDE.
If you need a timer in your project, you can just drop one onto some sort of schematic, and wire it to other components. If you want to configure these peripherial units, there is no fiddling with registers, you simply double click the schematic icons.
If you want to see it in action, you can visit Cypress’ YouTube-Channel.
Atmel ATtiny 104 Xplained Nano
Well, a small Xplained kit. The guy at the Atmel booth told me, that it was just relase on Tuesday. It has one LED, one push button and an onboard Programmer, based on an ATmega32U4. You can learn more here. This board is currently not available, but it will soon. It will be about 4.50€
There is the new ATtiny104 on it. It is a quite small MCU, it only has 1K of flash, but it has a very low power consumption. (I don’t remember exact numbers)
I haven’t found documentation about this Xplained Nano yet, but I’ll tell you what I’ve found out:
- There is an oboard programmer (not debugger), which is based on an ATmega32U4. It names itself “mEDBG”. As far as I know it is used in some other Xplained kits too.
- The LED is connected to PORTA 5. It is active low (so when you write a logic 0 to PORTA 5 the LED will be on)
- I suppose that the pushbutton is connected to PORTB 1. Please note, that it is active low, with no external pullups installed (so you have to enable the internal pullups of the ATtiny, and when the Button is pressed, the according PINB-Bit is low)
To be continued…
I really appreciate, that the manufacturers gave those boards to us and I’m really looking forward to work on projects with those.
As you can see, I proudly present this new blog to the world.
