New York is coming on strong as a hardware epicenter — exciting hardware culture can be found at every turn. Tomorrow, we’re bringing food and fun to one such event, the monthly MakeIt NYC meetup.
MakeIt is hosted by PCB.ng, a Brooklyn based PCB manufacturer and board stuffer whose mission it is to make electronics manufacturing available to everyone. [Sophi Kravitz] will be on hand and speaking about Hackaday.io and the Hackaday Prize. There are many other talks lined up, including The LED Artist (amazing work if you haven’t seen), Microchip who will show off their new Chip-KIT Wi-Fire, Thimble (an electronics subscription service delivering monthly hardware kits), and Botfactory’s Squink, a desktop electronics manufacturing machine.
In addition to the planned talks we’re always interested in seeing the projects you’re working on. Bring along anything that fits in a pocket or a backpack. We’ll see you there!
We have just opened up registration for Hackaday | Belgrade — a hardware conference on April 9th. Get your ticket now and make arrangements to visit Belgrade this Spring. Tickets are inexpensive, travel costs from other parts of Europe are very reasonable, the weather will be beautiful, and the all-day madness that we have planned will make you wish it were a week instead of just sixteen hours. These tickets will sell out so please share this post with your friends so they are not left ticketless.
Packed with Amazing People
Hackaday is a global community and that is what makes Hackaday | Belgrade spectacular. We are still accepting proposals for talks through February 15th but haven’t yet made all of the decisions regarding presenters — you should submit a proposal! We’ll publish an article about all of the presenters once we have wrapped up the call for proposals. Expect to hear back about this around February 22nd.
One thing I am very excited about is that Mike Harrison will be at the conference. His talk will cover his exploration of an absurdly expensive and complicated relic which was used in the 1950’s for large-format video projection. Mike’s ability to unlock understanding of complex (and awesome) electronics is quite amazing; this talk is not to be missed. But Mike is just one of a dozen presenters from all over Europe. Several members of the Hackaday crew will be on hand and the venue will be packed with hundreds of fellow hardware hackers. You won’t want to miss this.
The central feature of the badge is an 8×16 LED matrix driven by a PIC microcontroller. It’s running a USB bootloader which will let you flash your own custom code without needing a programmer. We were speaking with some of our friends over at Microchip regarding the bootloader and they offered to supply all the microcontrollers for the badge, an offer we were happy to accept.
Voja has already programmed the first demo application seen here, it’s Tetris written in assembly language. Impressive!
We were overwhelmed by the popularity of badge hacking at the Hackaday SuperConference last November. You can bet that badge hacking will be one of the most popular activities at Hackaday Belgrade. I have written a hardware emulator to work on some animations. It uses the SDL2 library to display the LED matrix and take three button inputs (the final badge design will have four buttons arranged in up/down/left/right configuration). Our hope is to host a demoscene competition that is open to anyone, whether you can attend the conference or not. More on that later.
Live Music and Hacking
As the evening sets in and the talks wind down, we have lined up bands and DJs to take the stage and carry us well into night. You won’t have to stop the badge hacking or anything else that you’re into, but you won’t have to solder in silence either.
As you can tell, this conference goes way beyond talks. This is hardware culture and you’ve just got to be there. Running from 10am until 2am, there’s more than enough to keep you occupied for one day. But make sure to hang out on the event page to get inside information on other non-formalized social events that will happen the night before and the day after. See you in Belgrade!
[Bunnie Huang] is now officially the person who wrote the book on electronics manufacturing in Shenzhen, China. His Crowd Supply campaign for The Essential Guide to Electronics in Shenzhen has blown way past the initial goal. [Bunnie] is the first person who comes to mind for anyone needing help getting their electronics built in the region.
The books is meant as a travel companion. Hackaday was in China last June and toured the markets of Hua Qiang Bei. They are incredibly overwhelming, but people are very nice, willing to help, and none of them speak English. [Bunnie’s] approach is pages with squares you can point to in order to express your meaning. Standing at the capacitor stall? There’s a page for that. Gawking at a booth packed full of LEDs and need them in reels instead of tape? That’s in the book too. Even better, this isn’t a one-way thing. You should be able to understand well enough what they vendor is trying to convey as they point at the pages to answer your questions. This is certainly better than our method of trying to find pictures of addresses and Chinese characters on our phones. Everything is at the ready.
It doesn’t end there. The images of the book’s table of contents shows that you’ll get help with getting into the country, getting around once you’re there, and making the deal when you do find what you need. If you’re ever going to make the trip to Shenzhen, this is the first thing you should put in your backpack.
Since you’re already in the mood to purchase something made of paper, we think you’ll be interested you in this gorgeous Hackaday Omnibus Vol 02. It’s 128 pages of the best original content published on Hackaday over the past year, including the stunning artwork of Joe Kim.
Have you heard that Microsoft is testing underwater data centers? On the surface (well, actually on the ocean floor) it’s not a bad idea. Project Natick seals a node of servers in a steel pipe for an undersea adventure planned for at least 10 years. The primary reason is to utilize cold ocean temperatures to keep the machines cool as they crunch through your incessant Candy Crush Saga sessions.
Passive cooling is wonderful, and really drops the energy footprint of a data center, albeit a very small one which is being tested. Scaled up, I can think of another big impact: property taxes. Does anyone know what the law says about dropping a pod in the ocean? As far as I can tell, laying undersea cabling is expensive, but once installed there are no landlords holding out their hands for a monthly extraction. Rent aside, taking up space with windowless buildings sucking huge amounts of electricity isn’t going to win hearts and minds of the neighborhood. Undersea real estate make sense there too.
But it’s fun to play Devil’s Advocate, and this one immediately raised my eyebrow. I read as much Sci Fi as time allows, and am always interested to see which authors are registering the best technology predictions. This is the second time in short order that I turn to [William Hertling’s] work. Back in November, Google announced a project to add predictive responses to Gmail. This parallels the premise of [Hertling’s] Singularity Series which begins with Avogadro Corp. Another major point in that novel is the use of offshore data centers.
This “security” is so outrageous we had to look for hidden cameras to make sure we’re not being pranked. We don’t want to ruin the face-palming realization for you, so before clicking past the break look closely at the image above and see if you can spot the exploit. It’s plain as day but might take a second to dawn on you.
So what’s the Arduino in there for? This is a digital Theremin, but check out the video below and you’ll agree that it sounds amazing and has excellent response. The aluminum antennas used for volume and pitch are attached to the top portion of the shield but it sounds like they’re not included in the kit. Don’t fret, you can use a variety of materials for this purpose. On the bottom you need to connect a speaker cable, and also a ground wire if that cable’s not grounded.
As the name implies, this is Open Hardware and we’re quite happy with the documentation on their site and the BOM (found on the GitHub repo). This design was shown off back in 2013 hiding in a pack of cigarettes. If you don’t want to build your own they’re selling kits on their site for 48 Euro delivered, or on Tindie for $55.
Okay, we’ve screwed this up so many times that we’re going to try to get it right here: the Theremin was not heard in the opening of Star Trek the original series, or in the opening of Doctor Who. It wasn’t featured in “Good Vibrations” either. As far as we can tell, it’s not used for anything in pop culture at all… but recognizing the sound and knowing what one is remains core geek knowledge.
