I have been tinkering for some time now on creating a pure hardware, highly reliable emoncms base-station solution that isn’t pain in the rear to set-up. The current approach is to use a NanodeRF, but that requires re-programming the unit with…
I have created a new version of the micro Internet of Things gateway RFM12b shield since the first revision had some drawbacks. The new version has a port that allows an OLED display to be plugged on top, this creating…
I’ve created a new shield for my micro Internet of Things gateway to allow driving an IR LED, added a micro SD card slot, FTDI pinout for easy programming and a visible status LED. I also added a TMP36 temperature…
The 2boots bootloader is a lovely bootloader, developed by Thomas Seiler that is Just 2kb of flash, fits into normal 2kb bootblock of most atmega chips Serial (stk500v1) bootloader, compatible with avrdude and Arduino IDE Additional MMC bootloader, can read…
The uIoT gateway shield has FTDI plug that I used mostly for serial debugging, while for programming I used a clone of the USBTiny programmer. I wanted to adapt optiboot for the uIoT gateway, as that will make it easier for…
As I ordered the wrong magjack for the uIoT gateway, I couldn’t test the Ethernet connectivity yesterday. I only could test that the Atmega328 talks to the ENC28J60 and ran a LED blink sketch. Today I decided to test out the shield…
My uIoT gateway project has been put on hold lately, I have the PCBs ready for more than a month now, but never had the time to make one and test it. I finally put one together today, but apparently…
I finished the painful assembly of Simon K.’s Micro Web Server, but was too tired afterwards to see if it works. With all these tiny SMD components, there is always the chance that something goes wrong. So today, I finally…
I have mentioned already, that I purchased Simon K.’s micro Web Server and have his permission to develop it further, see my micro IoT gateway post. I received it couple days ago but only had time to put it together…
As I already mentioned, I planned to have a RFM12B shield for the micro IoT gateway. Here is how it is looking, rendered in 3D, still work in progress, but the idea is clear. I wanted to keep the shield…
I have long wanted to make my own Internet of Things gateway and I wanted it small. I have researched for quite a while on the options, and finally decided to base it on the excellent work done by Simon Küppers…
