I haven’t had the time to follow up on the Atmega32u4 based new Funky, I now have finalized the board layout (I think). This has been quite a learning experience for me, I only started work on a remote node with this…
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…
pChart is a neat PHP charting tool, I have been using prior to switching to emoncms. Emoncms has multigraphs available, that are much more interactive, but they are slow too. I also have had some issues with certain feeds that…
With quite a few RFM2Pi boards out there, some issues started to pop up. When using the board to send time packets to emonGLCD, the board would interpret random serial gibberish as valid command and would switch its nodeID to…
I got myself Santa brought me a new laptop couple days ago, an Asus K56CM. I am no brand slave, I just pick one that fits the budget I set aside and what covers my basic requirements. I prefer not to spend…
I now have my evacuated tube solar water heater disconnected from the house’s plumbing system and in ‘winter mode’ meaning that I am crossing fingers it doesn’t freeze and break the tubes :). It does have electric heater element inside,…
Now that I have a PHP script that can find out my physical location, I wanted to calculate how far from home I am. Since ‘home’ is a fixed GPS coordinate and my actual position varies, I needed a method…
There is probably a million LED candle projects already, so I had to give it a try too :). I used bare Funky PCB and an ATTiny84 – no need for anything else indeed.The Attiny is set to run on…
Having breakfast this morning, we found that we have some old bread left that was about to be thrown to the trash.. or maybe not. Since it is winter now, birds are having hard time finding food, why not build…
Here is a small project with some potential in home automation. I had an idea to create a script, that would track my (and not only) location and use that information to make decisions for home automation. Some ideas: Climate…
I wanted to have quick access to certain measurements on my home monitoring system, most important the two hot water tanks (solar and heat pump) temperatures and room temperatures. I could, of course, have my laptop to check these, but…
