With the winter heating season knocking on the door, I decided to measure the room temperature in every room in the house. The Funky is perfect for the purpose, as a DS18B20 temperature sensor can be soldered directly on its…
USB on the Funky
I recently came across a neat little (literally) project called MicroFTX. It is incredibly small USB to serial adapter board based on FT230XQ (datasheet) from FTDI’s new X-Chip series. I thought it would be neat to throw in some native USB support…
What is this all about?
I guess that many Internet surfers that land on this site, actually wonder what is it that I am working on all about. I realized that indeed, it may be a good thing to describe it as well, putting it…
E-meter PCB ready
I have received the e-meter PCB and started making it. I forgot to buy couple elements and the 2×8 header won’t fit due to wrong footprint, but other than that it looks good:
Using Jeelab’s EtherCard library on the Micro Web Server (uIoT)
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…
Putting together Simon’s Micro Web Server
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…
Funky Wiki
I have started work on creating a wiki for the Funky sensor – find it here
Using Funky’s boost regulator get steady 3.33V from higher voltage
I would typically think of a boost regulator in the case when I’d like to step-up voltage, and such were my intentions when I introduced the LTC3525 boost regulator chip on the Funky sensor. The idea was to be able to…
Clocking the Funky sensor from RFM12B’s crystal
I have already expressed my thoughts on this, and of course could not resist materializing them. The main reason is that I would like to experiment with IR and RF stuff that requires precise timings. The internal oscillator’s frequency depends notably on…
RFM12B to Raspberry Pi board
I have decided to discontinue the TinySensor project and focus on Funky Sensor as they overlap a lot as functionality. These of you following my posts, know that I have a working prototype for a dedicated board for RFM12 to Pi connectivity,…
Remote keyboard and mouse for Raspberry Pi
This is a little heads-up for those of you (includes me) that don’t want to dedicate a mouse and keyboard to their Pi and would rather use their laptop’s mouse and keyboard. This is a bit different from running remote…
Display for my Raspberry Pi
[Edit] I have now undertaken another approach, worth checking it out here I recently purchased a 4.3″ TFT LCD screen, originally intended for attaching car backup cameras with the intention to use it as a status screen for my Raspberry…
Solar statistics
Earlier this year I purchased a 220l non-pressurized evacuated tube solar heater and installed it myself on my rooftop. It is a relatively cheap (~440 Euro) solution for domestic hot water. I chose the non-pressurized type because of its simplicity…
