RC transmitter module failure

Corona CT8J Module    I’m using a Turnigy 9X transmitter with ER9X firmware and a few different transmitter modules including this Corona DSSS 2.4G. I recently had a few control problems with the Corona DSSS system and finally noticed that tapping the module could make or break the RC link. […]


linux conference 2013

Embedded Linux conference talks on-line

It’s amazing how many of the tech-talks are poorly recorded. Considering all the experts that must be floating around and the huge community of follow up listeners, you’d think they could at least get the audio levels right. It’s also interesting, actually sad, how many of the speakers try to […]


Power supply replacement – Smart House – Kristil

After 10 or more years of operation there are probably many Smart House or Kristil home automation systems that are beginning to act up. One cause can be ageing power supplies.  The older power supplies, some linear and some switch-mode have been operating 24/7 and may have been running warm. […]

ESC with improved heatsinking

Raspberry-Pi for media and web browsing

I recently had another look at using the Raspberry-Pi as a media player with the idea of reducing power draw for general media, web browsing and email. In the past I’ve used XBMC on a modded X-Box. For the last couple of years I’ve used a full-blown PC running KUbuntu […]


Raspberry-Pi power mod and case

I’ve just received a R-Pi from Element-14. They said it would be mid Jan but it arrived late Dec. As with the others I’ve done, I decided to attach a 5V power lead and larger capacitor. See the previous posts. The case is from Soanar; possibly also available from Jaycar. […]

Mele vs Raspbmc and a TV

Initial Impressions After seeing the Mele in operation, yesterday I installed Raspbmc on the Raspberry Pi (R-Pi) to see how it compared. No problems during install but it won’t work with the hdmi on our TV. I could probably edit a file to force it to use hdmi; but this […]
