Only You Can Kick A Child’s Balls Into Space

July 27, 2012 by Mike Szczys 26 Comments

We had a lot of fun with that title. Of course when you’re talking about launching a thousand ping pong balls into space there’s no end to the puns which can be made. But this is actually a fantastic initiative to get people of all ages excited about science and near-space experiments. [John Powell] offers school children the opportunity to send an experiment into space. He’s Kickstarting the next launch, which is scheduled to take place in September. This way each entrant can fly their project for free, then get the results and a certificate back once the weather-balloon-based hardware is recovered.

There is one size restriction for the program. Each experiment must fit inside of a ping pong ball. But you’ll be surprised what can be accomplished. [John] reports that the most simple, yet interesting project is to place a small marshmallow inside the ball. As it rises through the atmosphere it will grow to fill the entire ball, then be freeze-dried by the the extreme temperatures. Some are not so low-tech. There’s an image of a tiny PCB holding a DS1337 and some sensors. It’s an atmospheric data logger that will provide plenty of information to analyze upon its return.

So You Want To Run A Kickstarter?

July 23, 2012 by Brian Benchoff 11 Comments

Earlier this year, [Anthony Clay] wanted to test the waters of Kickstarter with a low-risk project. The idea he came up with was a series of EE reference posters we featured in a Hackaday links post. Now that [Anthony]’s project is over, he decided to write about the whole ordeal of putting together a Kickstarter, giving all the gory details of putting on your own crowd-sourced project.

We’ve got to give [Anthony] credit for doing his homework. Even before he designed his first poster, he looked over unsuccessful Kickstarter campaigns to see what they did wrong. Once he knew what he was going to offer, [Anthony] put on his project manager hat and made sure he knew exactly what everything was going to cost, had contingency plans in place, and knew what his Kickstarter was before he spread the word.

The best laid schemes of mice and men ‘oft go awry, so of course [Anthony] hit a few snags in his Kickstarter. In his microcontroller quicknotes poster, a few weird underlines made it into the final draft of the voltage characteristics section. Everyone he showed this to thought it was no big deal, but this is something that should have been caught in proofing. Keeping in mind that [Anthony] was only doing a poster and not an electronics project, we think this is a valuable lesson for future Kickstartees.

If you’re wondering what the one thing that [Anthony] credits for the success of his Kickstarter, it’s actually the small blurb we featured in a links post. Once that happened, word started to spread and the funding picked up. To be honest, we’re impressed by that fact, and we’ll try to wield our powers carefully in the future.

Review And A Build: Makey Makey, A Banana Piano, And Mario

May 25, 2012 by Brian Benchoff 14 Comments

We’ve been getting a lot of emails on the Hackaday tip line about the Makey Makey. This business-card sized circuit board turns everything – bananas, Play-Doh, water, and people – into a touch interface.

There have been a ton of blogs that have written about the Makey Makey Kickstarter and debut at the Bay Area Maker Faire, but Hackaday has been mum on the pending release of the Makey Makey. There’s a reason for that: [Jay] and [Eric], the MIT Media Lab rats who came up with the Makey Makey, offered to send a demo board out to somebody at Hackaday. Well, here’s the review of all the cool stuff you can make with the Makey Makey.

Viper Flight Simulator (a La Battlestar Galactica) Finished

May 22, 2012 by Mike Szczys 13 Comments

Here’s a story about some guys who set out to build a flight simulator for the Viper from Battlestar Galactica. The goal is to bring a grand project to the Maker Faire. This is a recurring challenge for the group, which has participated over the last several years. But this year they decided to go big and mounted a successful Kickstarter campaign to help with the cost.

The best place to get the build details is their progress updates page. Each week the cadre of teenagers tried to post some info about their progress, and we’ve got a big grin on our faces after reading through them. The simulator aims to provide you with as much of a space flight experience possible given the restraints which gravity imposes. The cockpit can roll and pitch a full 360 degrees in each direction. Of course safety is a concern and they were careful with their frame design and pilot restraint system. But so much more goes into this than just the physical build. There’s sound, lighting, and the virtual simulator, all of which have been complete at an impressive quality level. There’s a ton of video posted and we’ve embedded one short clip after the break showing off the cockpit’s dashboard.

Tindie: An Etsy For Electronics

April 30, 2012 by Brian Benchoff 39 Comments

If you have a finished project you’re now bored with, here’s Tindie. It’s a one-man operation headed b [emile] that hopes to connect makers with people who think DIY projects are really cool and have money.

There are already a few websites that cater to the builder who wants to sell projects: Kickstarter for one, but this is based on the concept of campaigns. Tindie aims to be a techie etsy, according to [emile]’s market research post on reddit; a places for makers with a soldering iron to sell stuff, but who are baffled by the concept of knitting.

Right now there’s nothing to buy on Tindie – [emile] is looking for hackers to sell their projects so the store doesn’t launch with an empty stockroom. If you’ve got an old project sitting on your shelf that you’d like to sell, put it up. [emile] is only taking 5% of the sales – just enough to pay for the hosting. Hopefully it will be popular enough for the eventual Tindie/regretsy blog.

FPGA Arduino Shield Uses Kickstarter As A Preorder System

July 17, 2011 by Mike Szczys 35 Comments

[ Jack Gassett] is working on an FPGA shield for the Arduino. At first the idea of this expansion board seemed a little silly. But [Jack] mentions that the FPGA board can be quite useful for adding higher-order electronic complexity like HDMI capabilities to an Arduino. We’re not totally sold on the idea, but he’s not making the board solely for use with an Arduino either.

The plan is to use a Xilinx Spartan 3A FPGA which comes in a ball-grid array package. And that is the reason [Jack] decided to use Kickstarter for this project. He shared some of his issues with BGA components in a home manufacturing process a while back. To get these working reliably you need to have them professionally assembled, and that requires a sizable upfront investment. But as we read through his proposal it struck us that he’s actually using Kickstarter as a preorder system. You can get a base model with just the FPGA soldered on the board for $55. Not bad considering the chip will cost you at least $20 without assembly. Each level up includes a few more components like SRAM or add-on PCBs.

We get a lot of tips pointing to Kickstarter proposals but this is one of the few that seems right on the mark for supporting open and innovative development. Great work [Jack]!

Trobot: Kickstarting The 6-axis Minature Robot Arm

June 7, 2011 by Mike Szczys 10 Comments

Having already made it to three hardware development versions, [Toby Baumgartner] is looking for some financial backing to make version four of this robot arm possible.

He’s modelling the arm after much larger ABB industrial robots. Like those, it mounts on a stationary base, and features movement along six axes. The first couple of iterations even used ABB Software’s RobotStudio for control. This is the same software used by the full-sized robots, and features a special design language to integrate the robots into just about any production facility.

We don’t think the need for high-end software used with these small manipulator arms is very great, but we could see the finished product used for small-scale assembly line work some day. In the mean time these might be useful in your own projects. [Toby] has been using an mBed microcontroller board as the hardware driver. It communicates with the computer via an Ethernet connection and he’s even working on an Android interface right now.

Check out a video demonstration of version 2 and 3 embedded after the break.
