What was your most interesting recent non solar project?

We shoot at 2 l bottles for targets, when I take it for the kids to play with at my buddy's house. You can hit them at 40 yards fairly easily.View attachment 216208

Looks like about when I hit one with my .458 Socom😃 with 31gr of H110. Behind a 350 gr Barns TTSX they open up to about .97”

Here's the only other picture I have to show how hard it shoots. Water cooler bottle before and after. I built it to look more dangerous than it was but it turned out to be more dangerous than it looks

I've always wanted to make something that launches golf balls. I've had plenty of fun with walnuts in a potato gun, quarter sticks in a potato sent airborne are a blast as well...
Yours is next level.
Thanks for some inspiration

Be careful if you use acetylene for the propellant it has a sharp pressure curve. You have to account for it or you can make a metal fatigue bomb instead of a toy.
 
Solar Powered, Remote Controlled, Double Barrel Mortar Launcher
Mortars of the standard 4 to 5 inch mortars you can by at a fireworks stand

This launcher sits in field about 350 feet from my sons back porch.

4 Buttons on remote:
First opens hatch and arms the launcher
Second launches mortar tube one
Third launches mortar tube two
Forth closes hatch.

The hatch cannot be closed within 15 seconds of initiating a launch (give the fuse time to burn and launch)
The hatch will automatically close 15 seconds after initiating the second launch or 30 minutes after initiating a single launch.

planted some plum trees
How deep did you make the hole underneath? I worked as a gardener for 7 years and i used to plant olive trees. I used a mini excavator because they insisted we dig holes at least 120 cm deep (around 4 feet). It helped greatly the development of that tree in the first two years, making it reach a bigger size much earlier.

Gotta let those roots go free...
I love olives, wonder if I could plant them in PA; my fig does pretty good every year.

There is not much difference in latitude. The ones i worked with were in Umbria, 800m elevation and they did pretty good. During the winter we could get -10 celsius and i never saw any damage. As a gardener you always hope for a cold winter because it kills a lot of parasites making the work much easier. We used the olives to make ovile oil, there is a big olive oil culture here in Italy, there is a lot of people that make their own.
