Hi /diy/! So I'm a first year EE student and I have to

What about solenoids?

>>945927
look up solenoids

this doesnt sound like a real 1st year project. I think you chose to do this. what is your actual assignment?

this project is beyond 1st year EE.

too many mechanical components that will be costly to produce a working product that will function like an actual whack a mole and not fall apart on the first whack.

pick something simpler like a lite brite.

Man, I just don't get the school systems in other countries.
What exactly do they teach in 1st year EE where OP is at?

i'm pretty sure that whacking real moles is illegal

It sounds like it would be pretty simple to pull off honestly. I would mount my moles on a couple of drawer slides with a spring trying to push them up. Then I would rig a solenoid to a latch to hold them down( like a door latch). Then place a switch where its actuated by one of the slides when the latch is holding it down. Add some logic/micro controller and bobs your uncle

These pretty much.

Use solenoids for the up/down movement.

Do something like pic related to detect hits.

Basically, you have a spring that holds a stick that's connected to the outer container (the mole, in your case, likely something like a solo cup) above an NO switch (best practice is doing stuff on close, not on open), so that when someone hits it, the stick presses the switch's button (use like a rubber dome switch like you find in keyboards/remote controls).

On the electronics side, you want to only iterate the score when the particular solenoid is activated and only once per activation. Your prof would also probably be impressed if hitting the switch also triggered an interruption of your normal timing sequence for how long it stays up causing it to go ahead and go down when it's hit.

Real Whack-a-mole games use air cylinders and solenoid-controlled valves.

Oh, and the targets are on springs and when you hit them they drop down a little and actuate a microswitch which indicates they've been hit.

>>946006
In this line of thinking, what about using inflatable moles? You'd need some sort of valve that would give way under pressure when you hit it and then reseal itself. Then to make them pop up you'd just reinflate using a separate electronically controlled valve.

Sorry for my late reply guys, anyways I have a good idea of how to get started now. I found >>945965 especially helpful, but I will consider everyone's notes.

Cheers ^^

Just because it's too complex for whatever backwater you grew up in doesn't mean it is for the rest of the world tripcunt.
