--- Quote ---Entertainment value in making & using the thing: £priceless. :thumbup: --- End quote --- Can't argue with that :) Good fun project with a practical application at the end of it :thumbup: If we worked out what most of the things we make would cost in the "real world" then we'd all be either poor (made for ourselves) or stinking rich (if anyone would pay those unbelievable prices!) :) Ralph. |

I'd fill it with something and make a feature of it! :thumbup: Ralph. --- End quote --- Here in the US, if the burglar cuts himself why breaking into your shop, he can sue you for the injury. :doh: SAM |

The same sort of madness affects this side of the pond too, Sam :( There's only - in 15 years - been one burglary here. The chap who owns the place spoke to "someone he knows", which about 2 days later resulted in all of the stolen goods being returned, and someone spent some time in hospital getting over some broken limbs. The place has never been touched since (touch wood). Just to add a little footnote to this project, came to it this morning & it wasn't working... seemingly random LED blinks, unresponsive, etc. Well, much diagnosis later, I discovered that two solder blobs happened to be touching on the keypad, which meant the machine thought the "A" key was being pressed continuously. Oops..... Double-whammy, when I went to fix it, one of the solder pads broke off. Damn! Eventually, I had to disassemble one of the broken keypads, scratch the green layer off (the solder mask IIRC) a few mm of the tracks, and solder directly to them. It was painful, slow and tedious, but I got there in the end; re-assembled and all is well again. Phew! |

That's just a posed photo... The few bits of swarf visible on the keypad were from where I was trial-fitting it. In the end, I used a different keypad (I bought 5 in total), but what with the solder pad problem, I've ended up wrecking every single one, so the k/p that's actually in use might be that one, or maybe not, I've no idea... |
