[Sir Keyboard Commando] just emerged from his machine shop to show off the 1/6th scale model of a Civil War mortar which he recently finished fabricating. It started with some bar stock that measured four inches in diameter and accepts steel balls the size of golf balls as ammunition.
The bore diameter is 1.725″ which gives just a bit of clearance for the 1.685″ golf ball specs. Each of the steel balls weighs in at just over 11 ounces. You get a really good look at the finished mortar in this test-fire video. It’s quite small but [Sir Keyboard Commando] reports that the full assembled unit still weighs in at a whopping forty pounds.
This certainly isn’t an improvised weapon, but we’re quite surprised to see it being test fired. We’d bet it turns some heads that the local firing range.
Here is something we didn’t expect (NSFW). The machinima crew behind RedVsBlue, Rooster Teeth, actually did a hack!
The idea is simple enough, how could you experience driving a vehicle like in a video game – aka, third-person. With some steel bar, Canon 5D camera, and a 15inch monitor inside of a blacked out cab, they accomplished just that.
What surprised us the most, is the great difficulty and difference there is between the video game vehicle and the real life one. But all of us here at HAD know why; they need to replace the steering wheel with a joystick. While they’re at it they can make it wireless and remote-controlled. Finally a HUD would be easy enough to program (might we suggest processing). Oh dear lord, is the world ready for this!?
We asked for CNC projects, and wow did you guys deliver!
First up is [J-J Shortcut’s] MDF based CNC. He’s made three thus far, with the most recent costing about 180 euro and taking 2 months to build.
[Qwindelzorf] has also constructed a multitude of CNC machines including this industrial size router and this smaller miller.
Finally, [Mick’s] large steel CNC which just made its first cut only a week ago!
Keep up the great work guys, CNC machines are not easy to build and your accomplishments are ones for the record books.
[Ilias] let us know about his new HTPC case mod. He took a surplus Ammo-case and with a bit of work turned it into a livingroom eye-sore masterpiece. His build has some nice touches, including a slot-fed DVD player, switch-based fan control, and key-and-button “nuclear launch” type power-on controls.
A few things to learn from this project: Cleanly cutting holes in a steel case for the connectors is tough. You can see that [Ilias] did a pretty good job with it and in several cases used rubber gaskets to cover the rough edges. Secondly, the slot fed DVD had to be mounted upside-down. We assume this will be fine, but we’d like to hear a follow-up after a few years of heavy use. Finally, the GFAF (girlfriend acceptance factor) ran very close to critical on this build as [Ilias] didn’t clean up the metal shavings on his porch and ended up with rust stains everywhere.
Case mods are an enjoyable hobby. We hope this will inspire you to take the leap. If you do, don’t forget to send your completed project into our tip line.
