I’ve searched the net for a dummy security camera to place in front of my apartment, didn’t be able to find a good & free one. So designed my own.
The camera lens inside is actually a wide angle LED lens which is available on the market. Even without it the cam will look very real.
There are 4 holes for 3mm leds that will imitate IR lighting leds inside the cameras. There is empty space inside so if you like you can place a circuit to flash them, or anyhting else. Even a real camera can be fitted in, making my design not a dummy but a real security cam. Ebay is full of small cameras, many of them wireless that canfit inside.
There is also a dummy wireless antenna thing on top.
Modeled this after extensively measuring the dimensions of the instruments I have, which are; Olds Ambassador Cornet, King Master Cornet, Holton Collegiate Cornet and Bach Prelude Pocket Trumpet.
The air path gets wider all the way from the mouthpiece to the bell as it should in a cornet (excluding the valveblock area ). The mouthpiece is a 5B, as close as possible model of a well known cornet mouthpiece with wonderful sound. All parts are made or divided into smaller units, enabling this to be printed by using almost any printer, small or large. As usual I guess it will be a challenge to have the valves operate properly.
