Using my 1.8 TFT as a Raspberry Pi status display

I have been experimenting with my Raspberry Pi TFT display these few days with the intention to use it as a misc status display, heavily influenced by Mark‘s work. I collect most of my house’s telemetrics to an emoncms installation running on the server where I host this blog, so I will pull some of the data…

New RFM2Pi board in the works

Glyn Hudson and I have been working on a new RFM2Pi board revision, nothing revolutionary, just a small upgrade. The most important features of the board are: Atmega328 based, has more memory and hardware serial support Runs on the internal 8Mhz oscillator (to save unnecessary components) SMT used, board layout is optimized for pick-and-place machine;…

Receiving IR with Funky v2

I ran a quick test today to see how Ken Shirriff’s IR library behaves on the Funky v2. One of the things I noticed in my current design is that I don’t have a pin with timer output routed to the side header, so I changed that in the final product to enable easy IR…

1.8″ TFT LCD display on Raspberry Pi

[edit] This project is now available for sale in the store I figured my cheap 1.8″ TFT display is useless on an Arduino as it pretty much eats the available memory (20K for simple sketches), so I decided to try it on my Raspberry Pi. The most appropriate way to do so is to use Kamal’s…

Raspberry Pi as IP webcam

I noticed this Instructable the other day and had to try it since I had an old USB web cam laying around. I found that the instructions contained some inaccuracies, here are my steps: sudo apt-get install motion sudo nano /etc/motion/motion.conf Locate and change: Daemon = OFF to ON webcam_localhost = ON to OFF webcam_port = desired…

RFM2Pi firmware updates

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 some random number. This behavior is not observed when using the bard in ‘receive-only’ mode. To prevent…

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, I later modified the TinySensor to include the 2×5 pin header so it could plug…

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 desktop software, since what I actually want to do is to take use of my…

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 Pi. I got it from Ebay and it costs $25 delivered: Specs say it should…

Interfacing ‘Funky’ to Raspberry Pi

I am finding myself using Funkys for all of my recent projects, so I am thinking of discontinuing the TinySensor. I think the better approach would be to have various ‘shields’ for the Funky rather having hardware on board that anyone will rarely use, for example the SD card option, the voltage divider or the…
