A small change to this month's 'My Workbench' article, rather than talking about my control play ground project, I'll be talking about a small project which has recently taken a sizable chunk of my model railway time (not that I care). And no I don't feel guilty about it - my regular feature was pitched to the editor ( a few issues ago now) as a what's on my workbench series rather than a my control playground series.
This article started with one of my occasional visits down to the London meeting (at which I purchased an RFID starter kit). Well this article is one of the article options I had now that I have a starter kit (the other should be along next issue).
I've just finished listening to Security Now 248 and instatly thought about how to deal with the Sea Gulls in Aberdeen.
In it Steve talks about how he went about training some of the local animals with a sonic beam gun. Apparently it almost takes Sea Gulls out the sky, I've got to make myself one of these.
Bit of a short article this time around, I'd hoped to have been able to afford to be somewhat further along with this mini project by now. So I'll just cover the starting of the design phase.
Strange thing, I built an electronic kit and it half worked. After some testing the fault was found - I'd soldered in a regulator back to front. However the other regulator (wired the same way!) had been working fine. One of those moments in electronics of it works so I'm leaving it. I'm just surprised I managed to keep the magic smoke inside both of them.
