Hackaday Links: October 30, 2016

Diablo. Mech Warrior. Every LucasArts game. There are reasons to build an old PC, and no, emulation cannot completely capture the experience of playing these old games. [Drygol] set out to create a retro PC and succeeded brilliantly. The built features an old desktop AT case (when is the last time you saw one of them?), a 233MHz Pentium with MMX technology, an ancient PCI video card, and an old ISA Ethernet card (with AUI connector). Incoming upgrades will be an ATI 3D Rage PRO, PCI SoundBlaster, and hopefully Windows 98SE.

Right now, we’re gearing up for the Hackaday Superconference next weekend. It’s going to be awesome, and we’re going to announce the winner of the Hackaday Prize. We have another contest going on right now – the Enlightened Raspberry Pi Contest. The name of the game here is documentation. Build something, document it on hackaday.io, and you get some cool prizes.

Win Loot with the Enlightened Raspberry Pi Contest

Have an awesome Raspberry Pi project in mind (or maybe sitting on your bench right now)? Show it off for the Enlightened Raspberry Pi contest and you can score some excellent loot.

The Raspberry Pi has changed the face of experimental computers. These little $35 Linux powered boards can do incredible things. An active community has sprung up around the Pi. With it have come thousands of projects published on the web, in books, and in magazines. Many of the best Raspberry Pi projects are seen right here on Hackaday and published on Hackaday.io, which boasts over 1000 user created Pi powered projects (yes, we counted). Show us how you pull off those projects and you’ll be eligible to win.

Prizes and Judges

One thing we’d like to see more are really well documented projects — showing off everything anyone with an average skill set needs to perform the cool hack themselves. Do that and you’re well on your way to claiming one of eight great prizes! The grand prize winner gets a Pi-top Raspberry Pi laptop. First prize is the new Pi-top Ceed all in one. Second place is a 32×32 RGB Matrix kit. And the list goes on.

Submit your entry as a project on Hackaday.io and use the “Submit Project To…” option on the left sidebar of your project page to add it to the Enlightened Raspberry Pi contest. When entries close on November 9th, the Hackaday Staff will begin judging, bringing in some help to choose the top winners. This help comes in the form of a few VIP judges!

[Alvaro Prieto] is a Firmware/Electrical engineer who works on electronics for work and for fun. He previously worked at TI, Apple, and Planet. You’ve seen him hacking micro quadcopters, and as a presenter at the 2015 Hackaday SuperCon,

[Matt Richardson] is a Product Evangelist for the Raspberry Pi Foundation and the co-author of Getting Started with Raspberry Pi. We’ve seen [Matt] building heads up displays for bicycles, and removing celebrity gossip from our TV’s.

[Ken Shirriff] writes a popular blog (righto.com) on reverse engineering everything from chargers to microprocessors. Ken was formerly a programmer at Google and has a PhD in computer science from UC Berkeley. We’ve covered his microprocessor work as well as his teardowns of knockoff laptop chargers.

It’s All in the Details:

Entries are open now, show us the details that make great Raspberry Pi projects happen! The full rules can be found on the Enlightened Raspberry Pi Contest page. Fire up your soldering irons, warm up your 3D printers, and load up your favorite code editor. It’s time to start hacking!

ESP8266 MicroPython Contest Gives You the Excuse You Need

As if the prospect of having everyone’s favorite scripting language ported over weren’t enough to get you to install MicroPython on a spare ESP8266, there is now a contest for that. Over on Hackaday.io the MicroPython on ESP8266 contest is under way and you’ve only got until the end of August to submit your creation.

The prizes? First place gets an OpenMV camera board because [Radomir], who’s running the contest, has an extra one. OK, it’s not as lush as the corporate-sponsored goody-bag that we’ve got running in the Hackaday Prize, but there’s no reason that you can’t enter both. And if anyone wants to throw some more goodies into the pot, I’m sure they’d be welcome.

The rules are simple: use an ESP8266 or ESP8285 with MicroPython and post the project up on Hackaday.io. Bonus points are given for creating new libraries or hardware drivers. Basically, this just gives you an extra reason to get in there and play around. How cool is that?

If you need a start-up on MicroPython on the ESP8266, the official tutorial is great. We wrote up a first-look review of running MicroPython on the WeMos D1 hardware, but were plagued with (re-)flashing difficulties, so we’re going to have to give it another go.

Hack the Hackaday Demoscene from Your Own Home

We are just two weeks away from the Hackaday | Belgrade conference, and tickets have completely sold out. That means you can’t get your hands on one of these sweet hardware badges, but you can still take home some prizes for pulling off a gnarly hack with the badge firmware.

What we’re talking about is the Hackaday Belgrade Badge Demoscene – which includes a surrogate presenter program for anyone who wants to send in their own code for the device. You have two weeks to work on and submit your code — and we’ve made it really easy for anyone who has a working knowledge of C.

The day of the conference we will download all entries, and have a surrogate at the conference load it onto their badge and present it on your behalf. There is a separate pool of prizes for online entries, so hackers not at the con will win. And of course we’ll be celebrating the awesome demos with some posts on the front page.

No Hardware Needed

Hack in C for Abstracted Bliss or Be Hardcore:

You can use the emulator shown here to write your code for this badge. It comes with a set of basic functions that abstracts away the low-level hardware functions, and launches a demo window on your computer to test out your code. Check out this barebones C framework to get started.

For those that want more control, we have published the official assembly code that the badges will ship with (including a user manual). We’ll be squashing bugs right up to the day of the con). You can alter and compile this code yourself, or just start from scratch using the design spec if you prefer to travel the hardcore bit-monkey path.

Either way, you have an 8×16 display and 4 buttons to work with. Exercise your creativity and amaze us by doing a lot on a rather modest canvas. That’s what demoscene is all about.

How to Enter

Entry is easy, just start a project on Hackaday.io and submit it to the Belgrade Badge Demoscene contest using the “Submit Project To…” menu on your project page. You need to upload .C and .H files, or a precompiled .HEX to the file hosting part of your project page by Saturday, April 9th.

That’s the extent of the requirements. But it would be super fun if you recorded the software emulator playing your demo for all to see. The easiest way to do this is to record a video of your computer screen using your smartphone. Good luck to all!

Raspberry Pi Zero Contest Grand Prize Winners!

The Raspberry Pi Zero Contest presented by Adafruit and Hackaday came to a close last week, as the clock struck 11:59 am on Sunday, March 13, 2016. Since then our team of judges has been working to pick the top three entries. It was a hard job sorting through nearly 150 amazing creations.  In the end though, the judges were able to pick three grand prize winners. Each winner will receive a $100 gift card to The Hackaday Store.  So let’s get to the winners!

[JohSchneider] and [Markus Dieterle] both won Pi Zero boards and went on to win $100 gift certificates. [shlonkin] didn’t win a Pi Zero, but persevered and continued working on the classroom music teaching aid even without a Zero board. The top winners aren’t the only ones who are doing well. Everyone who entered has a head start on a great project for The 2016 Hackaday Prize.

I’d like to thank Hackaday’s own [Dan Maloney], [Kristina Panos], [Sophi Kravitz] and [Brian Benchoff] who joined me to judge the contest. The entire Hackaday staff is indebted to [Limor Fried] and [Phil Torrone] over at  Adafruit for coming up with 10 live videos, and providing 10 hard to find Pi Zero boards for our winners. The biggest thanks go to the entrants. If I could send a prize out to each and every one of you, I would!

Raspberry Pi Zero Round 1 Winners!

The Raspberry Pi Zero Contest presented by Adafruit and Hackaday has been going incredibly well! We currently have 132 projects entered, and there is still time for YOU to get in on the fun! The only problem entrants have had is getting their hands on these amazing $5 computers. We’ve made that easy by giving away ten Raspberry Pi Zero boards. The following projects were well documented, well thought out projects were selected by the judges. We’ve already informed the winners through Hackaday.io, and will be shipping out the Pi Zero boards to them right away.

Please join the judges and the entire Hackaday staff in congratulating the winners of the Pi Zero boards!

If you didn’t win, all is not lost! There is still time to enter the contest. The deadline is 11:59 pm PST on March 13, 2016. You’ll be in the running for one of three $100 gift certificates to The Hackaday Store!

Nessie, the Educational Robot

At the Lifelong Learning Robotics Laboratory at the Erasmo Da Rotterdam in Italy, robots are (not surprisingly) used to teach all of the fundamentals of robotics. [Alessandro Rossetti] and the students at the lab have been at it for years now, and have finally finished their fifth generation of a robot called Nessie. The big idea is to help teach fundamentals of programming and electronics by building something that actually uses these principles.

The robot is largely 3D printed and uses an FPGA to interact with the physical world through a set of motors and sensors. The robot also uses a Raspberry Pi to hold the robot’s framework. The robot manages the sensors in hardware with readers attached to the CPU AXI bus. The CPU reads their values from memory space, though, so the robot is reported to be quite quick.

The lab is hoping to take their robot to a robotics competition in Bari, Italy. We hope that they perform well there, since we are big fans of any robot that’s designed to teach anyone about robotics and programming. After all, there are robots that help teach STEM in Africa, robots that teach teen girls about robots, and robots that teach everyone.
