DIY Sentry Gun

at 5:03 pm. Filed under DIY Hacks, Electronic Hacks



This is a bunch of electronics that have been taped together to emulate a sentry gun. It is supposed to scan looking for the range of an object and when something moves it is supposed to stop and speak a command to what just moved. It doesn’t quite work properly but I am sure we will see it working a bit better in the future. The Parallax text to speech chip looks to work very well (looks like it has been discontinued). The voice phrases are recorded to the memory on the Arduino and by the sounds of it there are a ton of phrases in there! If you are looking for some inspiration to work from this might be the project to do it.
