RaspberryPi+TinySensor as EmonBase

I now have working setup with a TinySensor + Rasberry Pi  acting as an emonbase. I previously used PHP for this task, but the PHP serial class seems to have some issues on the transmission part plus it was a bit “heavy” for the CPU. I have created a perl script that will read the serial…

Dropbox shell script for RaspberryPi

Let me share a useful find: Dropbox Uploader is a BASH script which can be used to upload and download files from Dropbox, an online file sharing, synchronization and backup service. Since I am constantly switching SD card images, this is a useful tool to keep folders/files synced. I can also easily access these files on…

TinySensor 1.4 PCB is ready

I now have the TinySensor v1.4 in my hands, there are some small improvements over the version I last published, most notably that I added a 3.3V FTDI connector. You can’t use it to program the Attiny (..yet, I am working on that too), but it provides serial debug connectivity plus power source. Quite handy…

Manic Miner on my Pi

I have followed the instructions posted here and am now running Fuse Spectrum emulator on my Debian Pi , except for sound, all is perfect.. It reminds me of my good old ZX Spectrum back 27 years ago… For added realism, I plugged it to an old CRT TV I have:     Page views:…

Interfacing RFM12B to Raspberry Pi for cheap

I managed to interface one of my TinySensors to my Raspberry Pi via Pi’s UART. The idea is to use it to receive RFM12b transmissions and re-transmit on Pi’s UART where a serial gateway will pick the data and post to emoncms. I only need one-way transmission i.e. from the TinySensor to the Pi. Edit: [Two…

Got my Pi today

I was one of those geeks that had their alarm clocks set on February 29th this year to become quickly disappointed understanding that the initial batch or Raspberry Pis was sold out in seconds.  Later on when things settled a bit, I managed to make a pre-order. For a person that has been hooked on…
