Not a lot of heavy rain today after massive flooding at the start of the weekend. So I took the opportunity to start on a dynamic target.

Basically a bullseye on a hinge. So the core works fine. hit the bullseye and it moves according to how hard it's hit. I don't have a load cell or anything else yet and it was just starting to rain so another day. Not going to get too fancy yet anyway. The kids don't care, so long as it's something new and cool

I'm thinking of just something like a strongman game at a fair. Hit the lever and it sends something to hit a bell. In my case I need everything safely behind the target, so it will probably just be a bell that gets hit if it reaches a certain degrees. I haven't put much thought into it yet. Until then the kids are having fun like this.

Just made from wood I had available so not standard measure. The actual bullseye is 20cm diameter.

It's just for the kids and rubber balls, if it breaks I make a new idea.

It's just for fun

Nice idea, at the moment all I have is a couple of old bells off bicycles. So I'm contemplating having one on each side at different heights and a bit of metal on a spring attached to each side of the bullseye. A hit will ring one, a hard hit will ring both, a really hard hit will ring both and pop a flag or something, I don't know yet.

I want to keep it simple and compact. And cheap, so far cost has been next to zero.

That's a good idea. It would mean reloading which I don't want to do, because as is it reloads by gravity. But I could definitely make it spring something else up. In fact could probably spring load a line of things up one side which get triggered as the target goes up.... higher the target goes, the more get triggered

Dieses Video war inspiration für mich mal blind zu schleudern. 😁 😂

It's very simple, just a tennis ball on a t-hinge. It gets hit and swings out when the target moves about 45 degrees, but you could have a whole line of these if you want.

45 degrees works well for the kids, it needs a hard hit since they only use tennis balls. It's all pretty robust, so it takes a good whack to move the target.

Picture is the end result of a good hit.

No, not how I have it set up. you'd need a reload mechanism which is easily doable but not what I'm trying to achieve. Reloading the target is easy as it just reloads automatically with gravity. Reloading the hit flag would be a bit trickier.

If you don't reload it leaves the hit flag out in the open where it might get hit.

You could have a line of hinges up the side, if the target gets hit hard enough to move 20 degrees one hinge is triggered, if 40 degrees 2 hinges, 60 degrees 3 hinges etc,. Which would give you an idea of how hard it's being hit. I have it set for 45 degrees, which needs a hard whack with a tennis ball. We've been playing with it today.

Of course with a denser stone or something it would not need to hit so hard to move the target 45 degrees.

I may tweak it another day, but I only had two hinges left from another project and 5 kids and xmas just finished I'm broke at the moment So far cost has been zero as it's all wood and hinges I had left over.

I gave up on a bell, the bicycle ones I have aren't loud enough. When the target is hit it makes a bang, a bell is drowned out.
