Hackaday Links: June 19, 2016

Wait a minute. We’re almost through June and we haven’t seen anyone’s ‘DIY air conditioning’ setup. Oh the shame! How could we ever argue about thermodynamics otherwise? Here’s some copper tubing wrapped around a fan. Does it make sense? Assuming you’re making the ice (or cold whatever) in a room separated from the crappy air con, and you don’t have to pay for electricity (or ice), and you don’t mind hauling buckets of ice every few hours, yes. It’ll work. Now we can argue if you should put salt in the ice water…

I know I mentioned this in last week’s links post, but [Arsenijs]’s Raspberry Pi project is growing by leaps and bounds. He already has more than 33 followers to this project (awesome!) and 3.3k views on his project page. Not only is it climbing in popularity, but this is also a great use for the Raspberry Pi. You don’t see projects like this come around very often.

The Goliath is a quadcopter powered by a lawnmower engine. It was an entry in the first Hackaday Prize, but the project literally never got off the ground. There’s now a Mk. II version in the works. Goliath is getting a new frame made out of aluminum tube and rivets. There’s going to be ducts on the props, and this version might actually fly.

You did know Hackaday has it’s own Hackaspace, right? Technically it’s the Supplyframe Design Lab, but there are still a few skull ‘n wrenches hidden in the rafters. The Design Lab is hosting an open house this week on June 23rd, and the design lab residencies will begin July 1st. If you have an idea for something you’d like to build, here’s the residency application.

The LimeSDR is a powerful next generation software defined radio that’s currently on CrowdSupply The crowdfunding campaign ends in just a few days. It’s a very impressive tool, able to send and receive anything from 100 kHz to 3.8 GHz.

Last week one of our writers posted a review on the Monoprice MP Select Mini 3D printer. This printer is becoming stupidly popular, and Monoprice has depleted their inventory twice since then. I’ve been watching the product page for this printer for a while now, and here’s what happens: 1) Printer is out of stock, with an ETA of about a month in the future. 2) Printer is still out of stock, ETA is a few days away. 3) Monoprice has this printer in stock. This cycle seems to repeat every week or so.

Arduino Raycasting. When you think of raycasting, you probably think about Wolfenstein 3D, or other barely 3D games. You don’t need a powerful CPU like a 386 for raycasting – you can do it on an Arduino. The display is a 32×16 matrix of LEDs, control is through a Wii Nunchuck, and yes, head-bobbing is implemented. Here’s a video.

Dealing With Fallout

November 4, 2015 by Brian Benchoff 24 Comments

In just a few short days, Fallout 4 will be released and a substantial portion of the Hackaday staff will be taking the day off. As you would expect, a lot of people with 3D printers, soldering irons, and far too much time on their hands are getting pumped for the Fallout release. Here’s a few Fallout builds we’ve found over the past few weeks:

Pip-Boys

The most iconic thing you’ll find in a Fallout game is the Pip-Boy, the UI for the player and a neat wrist-mounted computer (that somehow has a CRT in it, I guess) for the player’s character. Hackaday’s own [Will Sweatman] built his own Pip-Boy 3000 that’s completely functional. The build uses a 4.3 inch touch display, a 10 position rotary switch, and a bunch of 3D printed parts.

Elsewhere on Hackaday.io, [Karl] is working on a functional Pip-Boy controller for Fallout, and [cody] built one with a Raspberry Pi. Of course, if you’re super special and have two thousand dollars to blow, Bethesda released a limited-edition Pip-Boy edition of Fallout 4 that’s compatible with most cell phones.

The Not Pip-Boys

There’s more to Fallout than just wrist-mounted computers, and for the true aficionados, there are gigantic gear-shaped doors. [TreyHill] has a partially finished basement with a gaming room tucked behind his very own vault door. The door itself is built out of plywood and rolls along a gear rack mounted to the floor. Will it hold up to a nuclear blast? Probably not. Is it up to code? It looks cool, at least.

[Lilykill] on Thingiverse is extremely capable with a copy of solidworks and produced a bunch of 3D models from the Fallout universe that includes power armor, ray guns, more Pip-Boys, plasma grenades, and a Nuka-Cola truck.

Fallout 4 for the Apple II

Fallout 4 will be available for the PS4, Xbox One, and PC, leaving out a large contingent of retro gamers. Fear not, lovers of the 6502: there’s’ a version for the Apple II:

This tribute to both the Apple II and Fallout was made with the Outlaw Editor, an SDK for pseudo-3D game development on exceedingly old hardware. There’s actual ray casting happening in this tribute, and it works just the same as Wolfenstein 3D or the like.
