Call for Proposals: Hackaday 10th Anniversary

call-for-proposals

On October 4th Hackaday is celebrating our 10th anniversary. We’ll be hosting a live event in Pasadena that day which includes some hardware hacking, some workshops, a mini-conference, and a party. Details to follow on most of this, but we are putting out a call for proposals to those who would like to present a talk at the mini-conference. We plan to record the talks, workshops, and events so that those unable to attend can also enjoy the festivities.

The mini-conference will be about 3 hours long on the afternoon of Saturday, 10/4. We are looking for approximately four talks on topics interesting to the Hackaday community. These will be no more than 20-minutes in length with a short Q&A after.

In addition to the talks we will invite a limited number of hackers to give 7-minute lightning presentations on hardware projects they bring with them to the event.

Talk Proposals

Please email your proposal of no more than 350 words to conference -at- hackaday.com. Preference will be given to speakers who are able to be at the event in person. Exceptional presentations given via video-chat will also be considered. Talk proposals should be submitted before Friday, August 22nd. Please specify whether you will present in person or via video.

Hardware Project Lightning Talks

Please email your proposal of no more than 350 words to conference -at- hackaday.com. Your proposal should mention what stage of development/operation your hardware is currently in. Lighting talks must be presented in person.

 

16-Bobbin Rope Braiding Machine Inspired by Surplus Store Find

When the Red Bull Creation build days were past, [David] pulled us aside and asked if we wanted to see the mechanical hack he’s been working on. He built this rope braiding machine, which uses 16 bobbins, with help from his brother [Jed].

Ideas for projects always come from funny places. [David] came up with this one after finding a rope braiding machine at Ax-man Surplus. This outlet, located in the Twin Cities (Minneapolis/St. Paul, Minnesota) has been the origin for innumerable hacks. Just one that comes to mind is this electric scooter project from the ’90s.

[David] wanted to understand how the mechanism, which divides the bobbins up into groups of orbiting spools, actually works. It’s both mesmerizing and quite tough to visualize how it works without really getting in there and looking at the gearing. Thankfully you can do just that if he follows through with his plan to turn this into a kit.

In case you don’t recognize him, [David] was on the 1.21 Jigawatt’s team during this year’s Creation. We’ve also seen a couple of hacks from him in the past like this half-tone drum printer, and this bicycle frame welding jig.

18-Channel PWM Aquarium Lights Provide Habitat-Like Life for Fish

Aquarium with variable LEDs

Whether you want to keep your fish happy or just need a good light show, this aquarium light fits the bill. It is the second iteration, but [William] calls it v1. That’s because v0 — which used a few loops of LED strips — never really met his requirements.

This build uses just six LEDs, each a 30 Watt RGB monster! To source about 350 mA for each, and to control brightness with 18-channels of pulse width modulation, he had to plan very carefully. This meant a proper aluminum project box and a beefy, fan-cooled power supply.

The driver board is his own design, and he etched a huge board to hold all of the components. Everything is driven by an Arduino Mega, which has 16 hardware PWM channels; two short of what he needed. Because of this he had to spend a bit of time figuring out how best to bit-bang the signals. But he’s putting them to good use, with fish-pleasing modes like “sunset” or the “passing rainbow” pattern which is shown in the image above.

If you need something a little less traditional why not house your fish in a computer case, complete with LED marquee for displaying data.

LED Cube in an Elongated Cube be Jammin’

LED cube and drive electronics inside an acrylic case

We get a lot of tips about LED cubes. They’re a great build to explore a lot of different things, from the circuit design, to current source and sink, and of course there’s the firmware. Why don’t we see a million of them on the front page? Well, we have seen a lot, but most of what is sent our way doesn’t exhibit such a clean build. It’s obvious that [Justin] took a lot of pride in his work on this 4x4x4 single-color cube.

Hidden away under one of the protoboards is an Arduino that drives it. A lot of the components were salvaged from the e-waste bin at his University. This includes the 12V AC wall wart he uses to power the device. A bridge rectifier converts to DC, and in addition to powering the LEDs there are a couple of USB charging ports. After the break you can see and hear it in action. The cube pulses to the music but the flip of a switch will disconnect the speaker if you want some peace and quiet to go with the light show.

If you’re looking for a challenge, this 8x8x8 RGB offering is several orders of magnitude harder to pull off… block out a lot of extra time if you do decide to take the plunge. We also heard that [Benchoff] might try to make a cube with some of those through-hole ws2812 pixels.

4-Minutes to Entry

If you think it’s too much work to write about your projects you’re simply wrong, and I’m going to prove it to you.

The first of this set of videos walks though the steps for submitting an official entry… I did it in under 4 minutes.  The second clip covers the extra details you need to post to meet the requirements for the first cutoff on August 20th.

This is the bare minimum needed for your project to be reviewed by the judging panel. But here’s the thing: get your basics down early, then refine as you go along. The Hackaday Prize celebrates the journey of developing interested connected devices. From now until November you should be working on the build and adding to infor to your project post as you go.

Did we mention your odds of winning this thing are really good?

Pwning Timberman with Electronically Simulated Touchscreen Presses

arduino-plays-timerman

What do you do if you suck at a smartphone game? Buy some in-game upgrades to pretend like you’re good? Screw that! [Valentin] did what any self-respecting hacker would: developed an automated system to play for him.

Granted, when you see the demo video embedded below you’ll realize there isn’t much strategy involved in this game. But that setup to simulate the touchscreen presses is pretty neat. We’re used to seeing mechanical touchscreen hacks but this one is electronic, using a couple of pads of copper foil tape and some relays to make it happen. Here’s the one caveat: you still need to be touching something with your hand. This just uses the relays to switch the connection between the pads and your body.

We’ve looked around for this before. Does anyone have a cheap, simple, and effective hack to fully automate presses on a modern touchscreen? Can we use a potato or something? Tell us below, but send it in to the tips line too!

20,000 Hackers

20k-hackers

What a pleasant thing to wake up and realize that we now have more than 20,000 Hackers on Hackaday.io. It wasn’t even two months ago that we celebrated passing the 10k mark. While we’re talking numbers, how about 2,075 projects, and 148 hackerspaces?

But what’s in a number? It’s what this stands for that really gets us excited! You took the leap and decided to show off what you’re working on while you’re still working on it. This is the key to pollinating ideas. One concept can result in many awesome spin-off projects. So if you haven’t yet written about that killer idea bouncing around in your head, do it now and be the inspiration for the next iteration of amazing hacks.

Much more to come

Our crew has been refining an overhaul of how the feed works to make it easier to know when and how your favorite hackers are updating their builds. You should see that functionality live in August. We’re also working on improving interactivity so that you can better find others with similar interests whether it’s just for casual conversation or to undertake an epic build as a team.

We’re certainly not above pointing out our own weaknesses. The Stack never took off. The idea seemed like a good one, but we need your help figuring out how to make it shine. Leave a comment below telling us what you think The Stack should be and how you think it should work.
