We’ll be at Bay Area Maker Faire and we want to have a beer with you on Saturday night.
Two years ago we headed off to the Bay Area Maker Faire and thought we’d invite friends and acquaintances to congregate at a bar on Saturday night. Anyone who’s been to the Faire (or been through a harrowing weekend of working a booth) knows that a bar stool and frothy beverage are a great way to recuperate. The turnout was amazing, we easily filled up O’Neill’s Irish Pub with that first meetup, and the Hackaday BAMF Meetup was born. Last year we packed it to the seams. This year we’re planning for an even bigger turnout that will go late into the evening.
I’ve only ever heard one complaint about this event; the band is too loud. This year O’Neill’s doesn’t have a band lined up so everything seems to be coming up roses. Come hang out with us! If you RSVP we’ll buy your first beer. Bring your stories, your easily transported hacks to show off, and have fun with the eclectic and enthralling community that turns out for this, the greatest meetup on earth.
Hackaday Letter from the Editors
If this is the first you’ve heard about this year’s meetup, you should subscribe to our weekly newsletter. Every week, a Hackaday Editor writes about what’s been going on that week, and shares a few of the most interesting posts from the past seven days. You can sign up for it in the sidebar to the right or with that signup link I just shared. If you’d like to know what you’re getting yourself into, here’s the most recent newsletter which we sent out on Friday. It’s a mini Hackaday delivered to your mailbox.
The Hackaday Crew will be descending on San Mateo next weekend for Bay Area Maker Faire. Will you be there? Gerrit and I will be looking in every booth and byway for amazing hacks, new hardware, and anything else that tickles the fancy of hackers everyone.
We certainly didn’t miss the massive tin spider seen above at last year’s event. But it’s a huge venue, and I’m always afraid we’re going to miss something epic. If you’re exhibiting and want us to stop by, leave a comment below. If you know of something awesome that we shouldn’t miss this year, we’d love to hear about that too.
I’d also like to invite you to hang out with Hackaday on Saturday night. When the Faire closes its gates, something amazing happens every year at O’Neil’s Irish Pub. Don’t miss it!
Need a Ticket?
Texas Instruments sent us 4 Friday passes, and 9 weekend passes which we want to give away. The fairest way of doing that is a drawing using Twitter.
To enter, simply Tweet something about your favorite 2016 Hackaday Prize entry, including @Hackaday @TXinstruments #FairePass in the message. Here’s what an example Tweet looks like (don’t worry, I’m not eligible to win).
On Sunday, 4pm PDT we’ll make a list of all the Twitter handles that sent out a Tweet, then use random.org to choose 6 random numbers from that list. The second giveaway will happen at 4pm PDT on Wednesday 5/18, using the same procedure to choose the remaining 7 winners.
All of the obvious contest stuff applies: employees and family of Hackaday, Supplyframe, and TI are not eligible. Results of the drawing are final. We can’t substitute other prizes (we’re just giving away extra tickets) and this giveaway has no bearing on any other contests or winner selection.
We’ve been admirers of the work [Eric] and friends have been doing over at TubeTime for years. One of the earliest we can remember is the decatron kitchen timer, and we still tell the story of [Eric] purposely leaving out button debouncing in order to make his vector flappy bird even harder.
TubeTime is back at it this year and we had the opportunity to speak with them at Bay Area Maker Faire. The group specializes in working with old tube displays and this year’s offering was spectacular in many ways. First off, the software side of things is an emulator running on an STM32 F4 Discovery board. The chips on these boards have a pair of 12-bit DACs which are driving the X and Y of the vector displays. Code to run the original ROMs was ported from existing projects, but the audio for the games was kind of a hack to get working.
This particular display is where things get really fascinating. The tube itself was originally manufactured as test equipment for television repairmen. What’s fascinating about this is that [Eric] had to rewind the deflection yokes himself to get it working again. Luckily he documented quite a bit about his initial research into this process and his experiments to remedy some distortion issues he encountered once it was working.
Make sure to head on over to TubeTime and read their overview of the Battlezone machine. After the break we’ve also embedded a few of our own pictures as well as the interview at BAMF.

A month before the Bay Area Maker Faire, there were ominous predictions the entire faire would be filled with BB-8 droids, the cute astromech ball bot we’ll be seeing more of when The Force Awakens this December. This prediction proved to be premature. There were plenty of R2 units droiding around the faire, but not a single BB-8. Perhaps at the NYC Maker Faire this September.
Regarding ball bots, we did have one friendly rolling companion at Maker Faire this year. It was a project by UC Davis students [Henjiu Kang], [Yi Lu], and [Yunan Song] that rolls around, seeking out whoever is wearing an infrared ankle strap. They team is calling it Project Naughty Ball, but we’re going to call it the first step towards a miniature BB-8 droid.
The design of the Naughty Ball is somewhat ingenious; it’s set up as a two-wheel balancing bot inside a clear plasic sphere. A ton of batteries work well enough as the ballast, stepper motors and machined plastic wheels balance and steer the ball bot, and the structure on the top hemisphere of the ball houses all the interesting electronics.
There is a BeagleBone Black with WiFi adapter, a few motor drivers, an IMU, and a very interesting 3D printed mount that spins the robot’s eyes – infrared cameras that spin around inside the ball and track whoever is wearing that IR transmitting ankle band.
As far as robotics project go, you really can’t do better at Maker Faire than a semi-autonomous ball bot that follows its owner, and the amount of work these guys have put into this project sends it to the next level. You can check out a video description of their project below.
I love the Hackaday crowd. Despite a long day standing at a booth or crawling the fairgrounds as a spectator, everyone still made it on Saturday night to the 2nd Annual Hackaday BAMF meetup and made it one for the annals of hacker history. Just look at that crowd… I see a couple of Hackaday Prize Judges, a friend I met in Germany (who I actually found out I first met at this same event last year), and many many more great people. I don’t want to spoil the fun so check out the full size over on [Rich Hogben’s] photo log and see how many you can identify.
We started this gathering last year as a come-as-you-are and bring-what-you’re-proud-of after party to Bay Area Maker Fair. We don’t rent out the bar — O’Neil’s Irish Pub in San Mateo — but we had a handshake agreement for drink tickets (thank you to Supplyframe for buying the first round for everyone) with the bartenders. The place feels like the perfect size, and before long we were packed into every available space. The ramp to the restroom area in the back was a gauntlet of conversation — enough room to walk by but you felt like you were interrupting people talking to those across from them.

The amount of hardware on hand was spectacular. Taking pictures of it was tough in the tight quarters. I got a look at the first prototype of the Pebble smart strap. I really enjoyed seeing OSHChip (pictured above) which is an ARM Cortex-M0 chip and BLE rolled into a DIP-16 form factor. [Sophi’s] HeartBeat Boombox was a big hit; it uses the heartrate and blood oxygen sensors seen above to drive a drumbeat. Those blinky glasses should look familiar. [Garrett Mace] and his colleague [Jason] were on hand. These Macetech glasses are from a couple of years back but don’t worry, they were sporting the newest RGB flavor which I’m told will have black solder mask and integrated controller among other tasty goodies.

Perhaps the best way to tell the success of the night is that there were a lot of friends in the room that I never realized were even there. The next day I met up with [Sarah Petkus] and [Mark Koch] and was surprised to find they had been at the Hackaday meetup and I missed them. The same thing happened when I looked at [Rich’s] album from the night and saw [Trey German] was there too. I wasn’t hiding and I wasn’t stuck in one conversation, it was just that kind of a party that makes the room feel like a TARDIS but somehow the night doesn’t last forever.
It’s hard to imagine BAMF without this Saturday gathering. If you missed it this year, add it to your calendar for next.
Single-board computing is hot on the DIY scene right now and riding that knife edge is C.H.I.P., a project currently in crowd-funding which prices the base unit at just $9. I was happy to run into the crew from Next/Thing Company who developed C.H.I.P. They were happy because, well, the project’s reception has been like a supernova. Right now they’re at about $1.5M of their original $50k goal. We spoke about running Linux on the board, what connectors and pinout headers are available, as well as the various peripheral hardware they have ready for the board.

The Bay Area Maker Faire starts today, but the Hackaday crew rolled in early for something new this year. Friday has traditionally been just for exhibitor setup but this year a few extra groups were on site to see everything come together. Most notably, school field trips. How awesome is it to skip the normal class schedule and hang out at the fair? Also able to get in are media and industry.
I had a great time. Watching everything get setup is often more interesting that seeing the finished display. It’s also much quieter, many fewer bodies (Saturday afternoon is usually a mad press of people) and people haven’t yet lost their voices or the fallen into the monotony of voicing the same explanation over and over again.
Above you can see a few of the friends I ran into. [Windell Oskay] is one of the 2015 Hackaday Prize Judges. He had a freshly minted copy of his new book which I first heard about when visiting Evil Mad Scientist Labs last fall. I also ran into [Kevin] who is the creator of the Arduboy. I first met him at BAMF last year and this year he makes a triumphant return with the new version of Arduboy which overshot it’s Kickstarter by an order of magnitude in just a few days. And who else should I bump into but [Brian Benchoff]. He lives in Pennsylvania and I in Wisconsin so we look forward to hanging out when Hackaday hits the road. I also said a quick hello to [Caleb Kraft] who was slinging veggie paella all evening.
[Brian], [Sophi], [Matt], [Jasmine], [Rich], and I will all be at tonight’s Hackaday Meetup. Anyone in the area won’t want to miss this one. There are a ton of awesome hackers already planning to clink glasses starting at 7pm. All you need to do to join in is RSVP.

Back to the action; I made a quick Friday first pass which still took about three hours. The setup changes just a bit each year… generally things are in the same places but of course returning exhibitors have made a year of upgrades and there’s always a lot of fresh and new on hand. I don’t remember seeing the probability machine last year. It has reservoir of marbles at the top which are being steadily dropped into the “Plinko” style peg-board showing a distribution which has a higher probability toward the center.

Here are just a few more favorites. The Kijani Grows booth has a couple of full aquaponics setups that are worth checking out. I spent some time with the Firepick Delta guys. Sand plotters are always fun and there’s a giant one in one of the booths. I may try my hand at lock picking in The OPen Organization of Lockpickers tent today. And [Louis] of SmartMatrix is launching his Kickstarter to bring fully-assembled versions to people who don’t want to solder the one available in our store.
That’s all for now, I’m off to see as much as is humanly possible. If you’re at the Faire today or tomorrow track us down for some stickers and other swag, and don’t forget tonight’s meetup that I mentioned above!
