Phones are getting increasingly more complex, more difficult to repair, and phone manufacturers don’t like you tinkering with their stuff. It’s a portable version of a John Deere tractor in your pocket, and Apple doesn’t want you replacing a battery by yourself. What if there was a phone that respected your freedom? That’s the idea behind the WiPhone, and soon it’s going to be be a crowdfunding campaign. Yes, you will soon be able to buy a phone that respects your freedom.
We took a look at the WiPhone a few months ago, and the idea was solid: make a simple, cheap, handheld device based on the ESP32 WiFi/Bluetooth wonder microcontroller. There are a few other various bits of electronic ephemera for scanning the buttons, an audio codec, and a speaker driver, but the basics of the build are just an LCD and ESP32. The entire idea of this phone is to make calls through WiFi, and given the state of VoIP, it’s a marketable product.
Astute readers may notice that the WiPhone doesn’t have a cellular modem. Yes, this is true, but putting a baseband in a small, low-volume project is incredibly hard. You’re limited to 2G if you don’t want to deal with Broadcom or Qualcomm, and they’re not going to be interested in you if you’re not moving a hundred thousand units, anyway. Also, you’ve got service plans to deal with, multi-country radios, and you’re probably next to a trusted WiFi network right now, anyway.
The WiPhone is designed to be hackable, with daughter boards that turn it into a rainbow or RC car, and easy to assemble. It’s also going to be a crowdfunding campaign at the end of the month. If you want a phone that respects your right to repair, this is the project to look at, even if you don’t need a cellular modem all the time.
Vantablack is the darkest pigment ever created, capable of absorbing 99.96% of visible light. If you cover something in Vantablack, it turns into a black hole. No detail is presented, and physical objects become silhouettes. Objects covered in Vantablack are outside the human experience. The mammalian mind cannot comprehend a Vantablack object.
Vantablack is cool, but it’s also expensive. It’s also exclusively licensed by [Anish Kapoor]’s studio for artistic use. Understandably, artists have rebelled, and they’re making their own Vantablack-like pigments. Now, the World’s Blackest Black is on Kickstarter. You can get a 150 ml bottle of Black 3.0, something that’s almost black as Vantablack, for £10.
The pigment for Black 3.0 is called Black Magick, and yes, there was a version 2.0 The problem with the earlier version is that although the pigment was blacker than almost anything else, paint isn’t just pigment. You need binders. The new formulation uses a new acrylic polymer to hold the pigment, and ‘nano-mattifiers’ to make the paint none more matte.
What can you do with the blackest black paint you’ve ever seen? Well, taking pictures of an object covered in the blackest black is a tiny bit dumb. This is something that must be experienced in person. You could paint a car with it, which is something I really want to see. You could follow [Anish Kapoor] around in the shadows. Use it as a calibration target. Who knows what we’ll do with the almost-Vantablack when everyone has it.
The PocketSprite is the tiniest fully-functional Game Boy Color and Sega Master System emulator. Not only is it small enough to fit in your pocket, it’s small enough to lose in your pocket. It’s now available as a Crowd Supply campaign, and it’s everything you could ever want in a portable, WiFi-enabled, fully hackable video game console. It also plays Witcher 3. And probably Crysis, because of the meme.
This has been a year and a half in the making. The first hardware version of the PocketSprite was revealed at the 2016 Hackaday Superconference by hardware engineer extraordinaire [Sprite_TM]. As [Sprite] has a long list of incredibly impressive hardware hacks like installing Linux on a hard drive and building a Matrix of Tamagotchis, he always has to keep pushing deep into the hardware frontier.
In 2016, [Sprite] showed off the tiniest Game Boy ever, powered by the then brand-spankin’ new ESP32. This was released as Open Source, with the hope that a factory in China would take the files and start pumping out mini Game Boys for everyone to enjoy. Now, a year and a half later, it’s finally happened. In a collaboration with manufacturing wizard [Steve K], [Sprite] is the mastermind behind TeamPocket. The pocket-sized Game Boy-shaped emulator is now real. This is our hands-on review.
All the kids down at Stanford are talking about neural nets. Whether this is due to the actual utility of neural nets or because all those kids were born after AI’s last death in the mid-80s is anyone’s guess, but there is one significant drawback to this tiny subset of machine intelligence: it’s a complete abstraction. Nothing called a ‘neural net’ is actually like a nervous system, there are no dendrites or axions and you can’t learn how to do logic by connecting neurons together.
NeruroBytes is not a strange platform for neural nets. It’s physical neurons, rendered in PCBs and Molex connectors. Now, finally, it’s a Kickstarter project, and one of the more exciting educational electronic projects we’ve ever seen.
Regular Hackaday readers should be very familiar with NeuroBytes. It began as a project for the Hackaday Prize all the way back in 2015. There, it was recognized as a finalist for the Best Product, Since then, the team behind NeuroBytes have received an NHS grant, they’re certified Open Source Hardware through OSHWA, and there are now enough NeuroBytes to recreate the connectome of a flatworm. It’s doubtful the team actually has enough patience to recreate the brain of even the simplest organism, but is already an impressive feat.
The highlights of the NeuroBytes Kickstarter include seven different types of neurons for different sensory systems, kits to test the patellar reflex, and what is probably most interesting to the Hackaday crowd, a Braitenberg Vehicle chassis, meant to test the ideas set forth in Valentino Braitenberg’s book, Vehicles: Experiments in Synthetic Psychology. If that book doesn’t sound familiar, BEAM robots probably do; that’s where the idea for BEAM robots came from.
It’s been a long, long journey for [Zach] and the other creators of NeuroBytes to get to this point. It’s great that this project is now finally in the wild, and we can’t wait to see what comes of it. Hopefully a full flatworm connectome.
The ESP32 is Espressif’s follow-up to their extraordinarily popular ESP8266 WiFi chip. It has a dual-core, 32-bit processor, WiFi, Bluetooth, ADCs, DACs, CAN, a Hall effect sensor, an Ethernet MAC, and a whole bunch of other goodies that make this chip the brains for the Internet of Everything. Everyone has been able to simply buy an ESP32 for a few months now, but the Hackaday tip line isn’t exactly overflowing with projects and products built around this wonderchip. Perhaps we need an ESP32 dev board or something.
The Hornbill is the latest crowdfunding campaign from CrowdSupply. It’s an ESP32 dev board, packed with the latest goodies, a single cell LiPo charger, and a USB to serial chip that will probably work with most operating systems. The Hornbill comes in two varieties, a breadboardable module, with a breakout board that includes an SD card slot, sensors, an RGB LED, and a bunch of prototyping space. The second version is something like an Adafruit Flora with big pads for alligator clips.
While this isn’t the first ESP32 breakout we’ve seen — Adafruit, Sparkfun, and a hundred factories in China are pumping boards with this chip out — it is a very easy and inexpensive way to get into the ESP32 ecosystem.
Internet of Things startup Garadget remotely bricked an unhappy customer’s WiFi garage door for giving a bad Amazon review and being rude to company reps. Garadget device owner [Robert Martin] found out the hard way how quickly the device can turn a door into a wall. After leaving a negative Amazon review, and starting a thread on Garadget’s support forum complaining the device didn’t work with his iPhone, Martin was banned from the forum until December 27, 2019 for his choice of words and was told his comments and bad Amazon review had convinced Garadget staff to ban his device from their servers.
The response was not what you would expect a community-funded startup. “Technically there is no bricking, though,” the rep replied. “No changes are made to the hardware or the firmware of the device, just denied use of company servers.” Tell that to [Robert] who can’t get into his garage.
This caused some discontent amoung other customers wondering if it was just a matter of time before more paying customers are subjected to this outlandish treatment. The Register asked Garadget’s founder [Denis Grisak] about the situation, his response is quoted below.
It was a Bad PR Move, Martin has now had his server connection restored, and the IOT upstart has posted a public statement on the matter.– Garadget
Vacuum formers are useful tools to have around the shop and also an incredibly simple technology. All you need is a plastic sheet, a heater of some kind, a table with a bunch of holes in it, and a vacuum. The simplicity and usefulness of a vacuum former mean they’re perfect for a homebrew build. That said, we haven’t seen many DIY vacuum formers around the Interwebs. Now, there’s a Kickstarter that brings vacuum forming to the desktop. If nothing else, it’s an inspiration to build your own vacuum forming machine.
The Vaquform is pretty much what you would expect from a desktop vacuum forming machine. A 9 x 12 inch forming area is equipped with ceramic heaters to soften the plastic sheet, and interestingly, an infrared probe (think a non-contact digital thermometer) to ensure you’re pulling molds when the plastic is ready, not before.
You can’t push a Kickstarter without some new and novel technology, and the highlight of this product pitch is the Vaquform hybrid system vacuum pump. This vacuum pump, “combines high airflow and high vacuum” and looks like someone slapped a brushless motor on a turbo.
This is a Kickstarter campaign, and so far it appears Vaquform, the company behind this vacuum former, appears to only have prototypes. There’s a big difference between building one of something and building a hundred. As with all Kickstarter campaigns, ‘caveat emptor’ doesn’t apply because ēmptor means ‘buyer’. If you contribute to this Kickstarter campaign, you are not buying anything.
Even though this is a Kickstarter campaign, it is an interesting tool to have around the workshop. Of course, there’s not much to a vacuum former, and we’d be very interested in seeing what kind of vacuum former builds the Hackaday community has already made. Send those in on the tip line.
