Cell phone signaler for the deaf community ?
Saw some signaler sold online but it is indeed will cost a Benjamin.
Anyone could have a DIY signaler to lit series of colorful LEDs when there is an incoming SMS, or incoming cell phone if the phone is rest onto the signaler ?
I remembered last time during the 2G phone era, it used to have these tiny gadget attached at the antenna and will emits light when there is an incoming message or incoming call.
Unfortunately it is no longer available these days.
