Re: Web shooter shop class - Part 2
Hey guys! I'm back on the forums after a long break.
On my design, I have some good news and some bad news.
The good news is that I have the solenoids, here, in my house. They work perfectly.
The bad news is that, first of all, they don't work with the button batteries like I hoped they would. Why? Because I didn't anticipate the solenoid coil to be so incredibly huge. It's around 2 and a half inches in diameter, and about 3 inches tall. It's very large. So, I am switching around to a 9V battery to power it, which is the lowest power source I can use.
This brings up another problem... I will have to change the way I was going to integrate it into the circuit because of the power source change. However, this doesn't mean it won't work in the circuit. The problem is that I have to run the charge to open it off of the microcontroller, but the micro only runs off of less than or equal to around 6V... which means I will have to change a bit of stuff about it to get it to work.
However, I expect the shooter will be done by the eighth of January, at the latest.
I use the term shooter loosely, considering I don't have a formula yet, need to build the canisters, etc.
