EAGLE Keyup Noise Toy

[unit_399]

I was showing my stepson how to breadboard circuits, when I came up with this keyup toy. Similar to the outdated CA3045 Whistler but uses the easy-to-find (and cheap) 555 timer IC. Good sounding and fully adjustable for sweep time and tone range. This is for my Amigos who are into noise toys and such. 73s.
