There’s nothing new, ever. It’s all been done. But that doesn’t mean you can’t invent something interesting. A case in point is the Motor Synth, a crowdfunding project from Gamechanger Audio. It’s what you get when you combine advanced quadcopter technology with the market for modular and semi-modular synthesizers.
The core feature of the Motor Synth is an octet of brushless motors tucked behind a plexiglass window. These (either through an electromagnetic pickup or something slightly more clever) produce a tone, giving the Motor Synth four-note polyphony with two voices per key. On top of these motors are reflective optical discs sensed with infrared detectors. These are mixed as harmonics to the fundamental frequency. The result? Well, they got an endorsement from [Jean-Michel Jarre] at Superbooth earlier this month (see video below). That’s pretty impressive.

A few years ago, new, innovative pico projectors, influenced by one of the TI development kits, started appearing in Kickstarter projects and other various DIY endeavours. Those projects fizzled out, most likely due to the cost of the projectors, but we got a few laughs out of it: that wearable smartphone that projected a screen onto your wrist used the same technology.
But there’s a need for a small projector, a pico projector, or in this case a femto projector. It’s the Nebra Anybeam, and it’s a small projector that uses lasers, and it comes in the form of a Raspberry Pi hat. We would like to congratulate the team for shipping the ideal use case of their product first.
The key features of this pico projector address the shortcomings of existing projectors that can fit in your pocket. This uses a laser, and there’s no bulb, and the power consumption can be as low as 3 Watts. Power is provided over a micro USB cable. The resolution of this projector is 720p, which is sufficient for a quick setup for watching a movie, but the brightness is listed as equivalent to 150 ANSI lumens, about the same as small projectors from a few years ago.
But of course the big selling point isn’t the brightness or resolution, it’s all about the smallness of the projector itself. There is a developer’s kit, a Pi Hat, a fit-in-your-pocket version with an enclosure, and a ‘monster ball’ version of the Anybeam.
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 Hackaday Superconference is over, which is a shame, but one of the great things about our conference is the people who manage to trek out to Pasadena every year to show us all the cool stuff they’re working on. One of those people was [Piotr Esden-Tempski], founder of 1 Bit Squared, and he brought some goodies that would soon be launched on a few crowdfunding platforms. The coolest of these was the iCEBreaker, an FPGA development kit that makes it easy to learn FPGAs with an Open Source toolchain.
The hardware for the iCEBreaker includes the iCE40UP5K fpga with 5280 logic cells,, 120 kbit of dual-port RAM, 1 Mbit of single-port RAM, and a PLL, two SPIs and two I2Cs. Because the most interesting FPGA applications include sending bits out over pins really, really fast, there’s also 16 Megabytes of SPI Flash that allows you to stream video to a LED matrix. There are enough logic cells here to synthesize a CPU, too, and already the iCEBreaker can handle the PicoRV32, and some of the RISC-V cores. Extensibility is through PMOD connectors, and yes, there’s also an HDMI output for your vintage computing projects.
If you’re looking to get into FPGA development, there’s no better time. Joe Fitz‘s WTFpga workshop from the 2018 Hackaday Superconference has already been converted to this iCEBreaker board, and yes, the seven-segment display and DIP switches are available. Between this and the Open Source iCE toolchain, you’ve got a complete development system that’s ready to go, fun to play with, and extremely capable.
The greatest bit of consumer electronics is shipping and the reviews are out: Amazon’s Alexa-enabled microwave is a capable microwave, but befuddling to the voice-controlled-everything neophyte. Voice controlled everything is the last hope we have for technological innovation; it’s the last gasp of the consumer electronics industry. This is Amazon’s first thing with a built-in voice assistant, and while this is a marginally capable microwave at only 700 Watts — fine for a college dorm, but it’s generally worth shelling out a bit more cash for a 1000 Watt unit — the controls are befuddling. The first iteration is always hard, and we’re looking forward to the Amazon Alexa-enabled toaster, toothbrush, vacuum cleaner, and Bezos shrine.
Need a laser cutter, like crowdfunding campaigns, and know literally nothing about laser cutters? Have we got something for you. The Etcher Laser crowdfunding campaign has been pinging my email non-stop, and they’ve got something remarkable: a diode laser
cutter engraver for $500. It comes in a neat-looking enclosure, so it’s sure to raise a lot of money.
A while back [Paulusjacobus] released an Arduino-based CNC controller for K40 laser cutters. There were a few suggestions to upgrade this to the STM32, so now this CNC controller is running on a Blue Pill. Yes, it’s great and there’s more floating points and such and such, so now this project is a Kickstarter project. Need a CNC controller based on the STM32? Boom, you’re done. It’s also named the ‘Super Gerbil’, which is an awesome name for something that is effectively a GRBL controller. Naming things is the hardest problem in computer science, after all.
The Gigatron computer is a ‘home computer’ without a microprocessor or microcontroller. How does it do this? A metric butt-load of ROM and look-up tables. This is cool and all, but now the Gigatron logo is huge. we’re talking 18 μm by 24 μm. This was done by etching a silicon test wafer with electron beam lithography.
If you’re looking for an Open Source computer, good luck. The RISC-V stuff isn’t there yet, and with anything else you’re going to be dealing with NDA’d Intel, AMD, or some other proprietary cruft. System76, however, makes the most big-O Open computer, and they will be announcing a new Open computer called the Thelio next month. It was on display at the Open Hardware Summit, although smartly there were no pictures taken of this box. Liliputing has reported on it, but there are a few things wrong with that speculation. No, it’s not RISC-V. We’re looking at x86 here. It’s a desktop. It has wood (walnut or maple). It doesn’t have enough cold cathode lighting to blind you, but I guess that’s a matter of taste. Everything will be announced in October.
I have a plan in the works to sell snake oil to people. Actually, it’s not snake *oil*, but it is derived from snakes. There are rattlesnake farmers out there, who breed snakes for meat (tastes like chicken!) and their skins for boots. The fascia of the skins is disposed of when this leather is being prepared, and this can be used as the base component of a glue, or something resembling gelatin. It’s basically no different than fish or animal glue, except it’s from snakes. This can be used as one of the ingredients in gummy candy. This is my plan: I’m going to sell snake oil, except it’s really snake-based gummies. They promote digestion and get rid of ions in your body, or something. Better living through snake gummies.
The paragraph you just read is a better business plan than this bit of snake oil. It’s a battery that recharges itself. It’s unclear if it recharges itself over time; if if it just recharges itself automatically, wouldn’t the battery just have more energy in it? It’s hitting all the checkmarks of snake oil too: there are references to Tesla being a ‘forgotten genius’, zero-point energy fields, and a countdown timer to their crowdfunding campaign. This rabbit hole goes deep.
Did you know Hackaday has a Retro Edition, specifically designed for old computers that somehow have web browsers? It’s true! Sometimes, we even add pics of people pulling the Retro Edition up on their ancient devices. [Steven McDonald] wondered if his Blackberry counted. Sure thing! If you can pull up the Retro Edition on your ancient computer, we’ll mention it in the Links post, too. We’re also taking suggestions on how to improve the Retro Edition; I’ll get around to improving it eventually.
The desktop computer is dead. No, I don’t mean computers that are meant to sit either on or underneath a desk. I’m talking about computer cases that are placed on a desk horizontally, probably with a monitor on top. The ‘monitor stand case’ was a mainstay for most of the 80s and 90s, but died out when CRTs became too heavy.
Now, though, there’s an interesting Kickstarter project that aims to bring the desktop computer case back, and it’s doing it as an upgrade to the classic Amiga 500, Amiga 1200, and Amiga 600 computers.
The idea for this project began all the way back in the 80s, with the Checkmate A1500 computer case. This case was designed to add expansion capabilities to the low-end Amiga 500 computer, transforming it into a desktop system with extra floppies, a hard drive, and an expansion port. In effect, you could have a ‘professional’ Amiga system for half the price of Commodore’s product offerings.
Now the Checkmate is back, this time with a case upgrade that will transform an A500, A600, A1200, or even the PPC Aeon Tabor A1222 motherboard. There’s another trick this case has to offer: it’s also compatible with MicroATX and Mini-ITX motherboards, meaning yes, there is now going to be a real desktop case that you can throw a motherboard in and a monitor on top.
The death of the desktop computer is an absolutely tragic tale that has resulted in people dropping towers on a floor and propping up their LCDs on piles of books. The reason why we do this is understandable — when CRTs got too heavy for plastic enclosures, computers became towers. Now, though, we’re all using featherweight LCDs, and computers could easily return to the desktop.
