Magenta Bat detector kit, MkIIb, build and testing

Описание: This video is about the building and testing of a bar detector kit that I purchased from Magenta. This is an old kit which has been around for years, other newer kits are available but I consider this kit just right! It’s easy to build and easy to use. The other kits seem to get more complicated with LCD’s and stuff you don’t really need.
The kits is available from Magenta at this website, and currently (Aug 2017) costs £38.80.

Over all the kit was easy to build and the instructions were good. I had three problems, firstly the headphone socket wasn’t long enough to fit through the side of the case so had to be glued into place. If I had realised that it wasn’t going to fit I wouldn’t have bothered drilling a hole in the case. Secondly on one of the two kits I bought the two nuts which secure the pots were the incorrect size, this took some head scratching as you really couldn’t see the difference. Luckily I had some spares. It was strange that the pots didn’t have the nuts (and washers) attached to them in the box but instead came separately in a small bag. If the nuts had been fitted to the pots then it would have been obvious that they were the wrong size before the kit was sent out. The last fault I had may have been caused by me. The mixer chip IC1 was faulty, this may have been static discharge or may have been dead on arrival?
The completed kit works really well and is simple to use, once you see some bats around you should be able to tune into them very quickly.
