This is a bit of a work in progress and will be updated occasionally. RC – Radio Control Used for all sorts of applications but mostly thought of for model control; planes boats, cars etc. This is about model control and references New Zealand frequencies but the theory can be […]
I’ve posted some notes here. I’m always interested to hear from anyone with Kristil related problems or questions, or with parts to repair. I designed the original system back in the late 1990s and still have a lot of the information and can repair most components. Triac Module notes: Looking […]
I’ve been using the tracker in my FPV plane for a while now and it has been working as expected. A couple of times I’ve forgotten to replace the disarm jumper on landing which just means the unit starts transmitting on the drive home. Although it’s sealed inside a foam […]
Video Distortion and Quality Using a San-Disk V-Mate to record video transmitted from a model plane I have long had a problem with tearing down the left side of the recorded video. It’s not seen on the monitor connected to the same video receiver. Finally I investigated and fond that […]
I opened Firefox and it just went off and would not restart. The power supply has failed; seems it won’t supply the load. It’s a AMD dual core something-or-other, about 3GHz I think, 4G ram and a 1G low profile Asus ENGT220 video card on a Asus MB. Asus; that’s […]
I designed and built one of these. Everybody needs one of these. I’ve had this one on test for some time now and it’s working well. If you have a computer or other electrical device running 24/7, out of the way in a corner or back room, what happens when […]
Update July 2019: I tried to use it again – I should have known better. This thing is a piece of crap. The designer of the user interface was either under orders and prevented from making a useful product or was a complete moron. As a device that you should […]
There is some talk about CAA introducing or updating rules that cover UAVs. Small UAVs can be quite technical and present an interesting challenge to many RC enthusiasts, hobbyists, technical schools and others. There are many potential practical applications including search and rescue, farming, forestry, conservation and many others. In […]
