If you’re near San Francisco this weekend, this is what you should be doing. It’s The 6th Annual Hackaday x Tindie MFBA Meetup w/ Kickstarter.
Come hang out with the hardware hackers and bring along a project of your own to get the conversation going. We’re excited to move to a new, larger venue this year. All the good of the past five years will come along with us, plus many benefits of exclusively booking out an entire venue. You can catch up with people who have been on their feet all day running booths — and usually see the stuff they can’t show you at the Faire. The crew from Hackaday, Tindie, and Kickstarter will be on hand. And you’ll get a glimpse of a lot of the cool people and projects you’ve admired on the pages of Hackaday over the years. It’s fun, you should go!
First beer is on us if you RSVP using the link at the top of this article. But we’re mainly publishing this today to show off the poster art. Deposit your adoration for this exquisite illustration in the comments below.
Amazing Art by Joe Kim
We love all of the original art that Joe Kim creates for Hackaday articles. It’s impossible to look at his poster for this event and be anything but overjoyed. Here’s a link to the full size image, but be warned that the file is 14.4 MB
We want to hang out with you at Maker Faire Bay Area! Put our after-hours meetup on your schedule with a Sharpie, because the 6th Annual Hackaday x Tindie MFBA Meetup w/ Kickstarter will be bigger and better than ever with a new venue that has plenty of room for everyone!
The hacker crowd descends upon San Mateo weekend after next to show off a year of creations at Maker Faire. On Saturday, May 18th, the Faire will close for the evening as our meetup heats up. Bring along some hardware to show off and get the conversation started. Whether you’re attending the Faire or staffing a booth all day, this is the perfect way to unwind.
New Place with More Space!
Every year we’ve been packed to the gills and it’s time to make room for more people. This year Hackaday and Tindie have teamed up with Kickstarter to rent out the entire B Street Station in San Mateo. It’s close by and has plenty of room to hang out with friends new and old. We’ll provide light food and the first drink is on us! Please RSVP so we know how many people to expect, and like we said, grab a project to bring along! This event is open to all who are 21 years of age or older.
Begin Your Weekend with HDDG on Thursday
Start the weekend off right with the HDDG meetup on Thursday night. In keeping with tradition, this special Maker Faire edition of the Hardware Developer’s Didactic Galactic is happen at the San Francisco Supplyframe office on May 16th. You’ll find a ton of people from out of town on hand to enjoy talks ranging from non-rectangular phone design and mitigating ESD in wearables, to getting your projects funded with PR stunts. Speakers include Christina Cyr, Mary West, and Mic Black.

Based on the WiFi / Bluetooth wunderchip, clad in a polycarbonate frame, and looking like something that would be an amazing cell phone for 2005, the WiPhone is now available on Kickstarter.
We’ve seen the WiPhone before, and it’s an interesting set of features for what is effectively an ESP32 board with some buttons and a screen. It’s become something of a platform, with expansion daughterboards for LTE, LoRa, a camera, a Bus Pirate, and a programmable NFC/RFID doohickey. If you’ve longed for the day of big ‘ol Nokia brick phones, want to hack your phone, but don’t really care about actually having cellular connectivity, this is something that’s right up your alley.
Although the WiPhone looks like a usable product that was designed by someone with a sense of design, it still is Open Source. You can build your own, and there are dozens of expansion boards that will plug into the back of the WiPhone for prototyping, experimentation, and RGB Gaming LEDs. There’s no cellular modem on the WiPhone, though; for calls you’ll have to turn to SIP or VoIP apps.
Considering how difficult it is to source a cellular modem in small quantities and the desire for a cell phone that respects your Right to Repair, we’ve got to hand it to the WiPhone for creating something people want. It gets even better when you consider this looks more like a product than the 3D printed pieces of electronic cruft we usually see, and we’re happy to see this crowdfunding campaign just passed its goal and is completely funded.
The 2019 Geneva International Motor Show has a number of “concept” vehicles. These are vehicles that usually include some cool feature that isn’t really practical — at least today. For example, in the past, concept cars have had adjustable color interior lighting, plug-in hybrid engines, and power windows — all things that would eventually become commonly available. However, today’s advances in computer-generated graphics have meant you can show things you can’t begin to build. Case in point: Goodyear has a video touting the Aero — a solid car tire that doubles as a propeller for your garden variety flying car.
To us, the thing looks more like a science fiction movie trailer than anything remotely practical. Four relatively small wheels with no central hub can flip and provide enough lift to propel a sizeable vehicle skyward. Even more interesting, is to transition modes from ground to flight, the vehicle balances on two wheels while using only two as propellers to generate lift.

What if there were something like a KVM switch for your micro programmer, logic analyzer, and other various tools? There was a time when KVM switches (keyboard, video, and mouse, by the way) were metal enclosures surrounding an absurdly complicated rotary switch. This fact has a few applications if you ever want to switch a whole lot of stuff; if you ever need a bazillion-pole, two-way rotary switch, don’t spend your money at Mouser or Digikey, just look at eBay for some really old KVM or parallel port switches. Modern times require modern solutions, so here’s a 16-channel, bi-directional switched bus multiplexer. It connects wires to other wires with USB control, and if you need something like this, you really need something like this.
The SensorDots Port MuxR is a crowdfunding project for a project that began as a programming jig for another project. The MappyDot is a micro LIDAR unit that’s about the size of a postage stamp and has a microcontroller. Obviously, programming those microcontrollers was a pain (and don’t get me started on buying pre-programmed microcontrollers from the manufacturer), but there was a solution: a custom programming rig with dozens of pogo pins that automated the programming of an entire panel of boards. It was a useful tool, and now it’s a good idea for a Kickstarter project.
The Port MuxR takes a set of eight pins, and sends that out to one of eight ports. Alternatively, it can take a set of four pins, and send that to sixteen ports. All of this is controlled via USB, and it works with 0-5V signaling. If you know what this means, you probably have a reason to be interested in it.
Is it a sexy project? No, not at all. It’s an 8-pole, 8-throw rotary switch, controllable over USB. It is interesting, and it’s something a lot of us are going to need eventually.
Thanks to internet commerce opening up a global marketplace, it is now easier than ever for a budding roboticist to get started. There are so many robot kits available, across such a wide range of price and sophistication, that deciding which one to buy becomes a challenging project in itself. Is there room for another product in the crowded introductory robotics market? Sphero believes so, and they’ve launched RVR to explore not just workshops and classrooms, but also to see if they can find a market niche.
At the low end of this market, we can go online and buy a super simple chassis – two small wheeled gear motors and a chassis plate of laser-cut acrylic – for pizza money. At the high end, we have robots that cost as much as a car. Sphero’s RVR slots somewhere above Wonder Workshop’s Dash, but below LEGO’s Mindstrom EV3. Products in this range are expected to take care of low-level motion control details, so beginners won’t get bogged down by things like PID tuning before their robot can drive in a straight line. Sphero engineers are certainly capable of hiding such annoying details from beginners, with their experience in consumer robotics.
But a big selling point here is completely opposite from closed-box consumer electronics: RVR is built to be extensible. Not with proprietary accessories & add-on kits like many of its competitors, but with the components we know and love on Hackaday pages: Raspberry Pi, micro:bit, and whatever else willing to communicate with RVR via its UART port and powered by RVR’s on board five volt power supply. Proper care and feeding of a lithium-ion battery is also one of the beginner-unfriendly details taken care of. But RVR isn’t finalized – one of the reason Sphero stated for launching via Kickstarter is to get customer feedback. Certainly the funding goal of $150,000 (easily met in a few hours) was unlikely to be the most important part for a company of Sphero’s size.
We hope RVR will help introduce a new audience to building their own robots. When they’re ready to grow beyond Sphero’s kit, Hackaday is happy to help show the way. If you have a 3D printer, there’s never been a better time to build your own robot. (Zerobot is on one editor’s to-do list.) Those fascinated by electronics can peek under the covers of low-level motor control, and there’s always room to explore high level machine vision and neural networks.
Whatever it takes to get you started, just get started!

If you thought “carbon nanotubes” were just some near-future unobtainium used in space elevators, don’t worry, you certainly aren’t alone. In reality, while the technology still has a way to go, carbon nanotube production has already exceeded several thousand tons per year and there are products you can buy today that are using this decidedly futuristic wonder material. Now there’s even one you can put in your pocket.
Created by [Simon], a designer in the UK, this small carbon nanotube array is described as “A simulated black hole” because the surface absorbs 99.9% of the visible light that hits it. Protected by a clear acrylic case, the sample of the material makes a circle that’s so black it gives the impression you’re looking into deep space. Unfortunately, no time-dilating gravitational forces are included at any of level of support in the ongoing Kickstarter campaign; but considering it was 100% funded in just a few hours, it seems like most people are OK with the trade-off.
[Simon] is well aware of the ongoing war between different methods of creating the “Blackest Black”, and he thinks he’s put his money (and by extension, his backer’s) money on the winner. Singularity is using a similar technology to the exclusively-licensed Vantablack, rather than a super-dark paint like “Black 3.0”. In fact he’s so confident that Singularity will appear darker than Black 3.0 that he mentions a head-to-head comparison is currently in the works.
If there’s a downside to the carbon nanotube array used in Singularity, it’s that you can’t actually touch it. [Simon] warns that while the acrylic case is only held together with magnets and can be opened for more careful inspection, actually touching the surface is absolutely not recommended. He says that even dust getting on the material is going to adversely effect its ability to absorb light, so you should really keep it buttoned up as much as possible.
While the Singularity looks like an interesting way to experience near perfect blackness, the concept itself is far from a novelty. A material that can absorb essentially all the light that hits it has important scientific, military, and of course artistic applications; so figuring out how to pull it off has become a pretty big deal.
