It's a bit like the tat drawer in the kitchen. Full of crap and nothing of use.

DIY Electronics - 555 Timer connected to relay and mobile phone
มุมมอง 4K14 ปีที่แล้ว
A basic 555 timer connected to a relay. When activated the relay is energised for 4 seconds which is connected to the speed dial button on the mobile. You could connect it to your car, garage, house, shed etc. For use as a simple intruder alert pager system.
what's that that just went flying past the window..? oh, it was my sanity, bye :D
Brilliant! I want to go camping now!
thanks
