FLiR Lepton Thermal Camera Module
My FLiR Lepton Thermal Camera Module has finally arrived from the USA. I managed to hook it up to my Raspberry Pi yesterday and successfully receive thermal images from it. The […]

8MHz Node Test
I’ve resurrected the Sensor Node project and I am experimenting in reducing the power consumption even further. This time I’ve removed the 3.3v voltage regulator from the circuit and I’ve […]
ATMega328P Power Saving Techniques
I was sent a link to to the following great article on power saving techniques for microprocessors and in particular the ATMEga328P which is the chip used in the Arduino. […]
A better Arduino IDE
As anyone who has used the Arduino IDE over time will tell you, this crappy piece of software has barely changed since the Arduino first surfaced. It has no autocompletion, […]
7mA in Sleep Mode
I appear to be getting 7mA current draw when the MCU is in sleep mode. This is not good. Even if left in sleep mode the battery would die in […]
No obvious increase in battery life.
After powering the sensor via a digital pin on the ATMega (see my last post) I can’t say i’ve noticed any increase in battery life. With a read and transmit every […]
Pin Powered Sensor
In an attempt to increase battery life further I’ve now got the HTU21D humidity and temperature sensor powered by a digital pin from the ATMega328p. In code the sensor is […]
Sensor Node Progress
I’ve made some great progress with the sensor node project over the last two days. After finally getting around the problems I was having with the software bugs and the […]
RFM69CW – Never ending issues
I have no idea why but my experiments with the RFM69CW have descended into chaos and frustration. At first I had the units talking to each other and sending out […]
