    Hackaday Prize Entry: The Minimalist Z80 Computer 

    realized he could build a Z80 microcomputer with $4 worth of parts from everyone’s favorite online auction house. The result is a $4 Z80 home computer, and a great Hackaday Prize entry to boot.

    So, what do he need to build a retrocomputer loaded up with Forth, CP/M, and Basic? A CPU is a necessity, and

    Hackaday Prize Entry: Visioneer Sensor HUD

    That’s a LOT of processing for a simple RasPi, in fact it’s too much to not be annoying as hell with lag I expect.
    Although, to be fair, the writeup here says ” two cameras, sensors, a Pi Zero” when in fact on a closer look I see it’s 2 Pi Zeros (which you could predict by the mention of 2 cameras).

    Hackaday Prize Entry: Fighting Dehydration One Sip at a Time 

    Humans don’t survive long without water, and most people walk around in a chronic state of mild dehydration even if they have access to plenty of drinking water. It’s hard to stay properly hydrated, and harder still to keep track of your intake, which is the idea behind this water-intake monitoring IoT drinking straw.

    Dehydration is a particularly acute problem in the elderly, since the sense of thirst tends to diminish with age.

    Hackaday Prize Entry: The Weedinator Project, Now with Flame 

    is building on a previous effort, which was a tractor mounted weeding machine (shown above). It mercilessly shredded any weeds; the way it did this was by tilling everything that existed between orderly rows of growing leeks. The system worked, but it really wasn’t accurate enough. We suspect it had a nasty habit of mercilessly shredding the occasional leek. The new version takes a different approach.

    The new Weedinator will be an autonomous robotic rover using a combination of GPS and colored markers for navigation. With an interesting looking adjustable suspension system to help with fine positioning, the Weedinator will use various attachments to help with plant care. Individual weeds will be identified optically and sent to the big greenhouse in the sky via precise flame from a small butane torch. It’s an ambitious project, but

    Hackaday Prize Entry: Bloodhound Autonomous Radiolocation Drone 

    If you’re a first responder — say, searching for someone lost in the outback, or underneath an avalanche — and you’re looking for someone with a radio beacon, what’s the fastest way to find that beacon? Getting up high would be a good idea, and if you’re using radio direction finding, you’ll want to be able to cover a lot of ground quickly if only to make the triangulation a bit easier. High and fast — sounds like the perfect opportunity for a drone, right?

    Hackaday Prize Best Product Finalist: Reconfigurable Robots 

    Reconfigurable robots have been around for ages. One of the first and most popular reconfigurable robots came out of the MIT Media Lab, and last year, DTTO, a modular snake-like robot, won the 2016 Hackaday Prize. There’s a lot that can be learned from a robot that can turn from a walker to a swimmer to something that clambers over rough terrain, and

    Ask Hackaday: Saving The World With Wacky Waving Inflatable Arm Flailing Tube Men 

    This is a solution to global warming. This solution will also produce electricity, produce rain in desertified areas, and transform the Sahara into arable land capable of capturing CO2. How is this possible? It’s simple: all we need to do is build a five-kilometer tall, twenty-meter wide chimney. Hot air, warmed by the Earth’s surface, will enter the base of the chimney and flow through turbines, generating electricity. From there, air will rise through the chimney, gradually cooling and transferring energy from the atmosphere at Earth’s surface to five kilometers altitude. This is the idea behind the Super Chimney, It’s an engineering concept comparable to building a dam across the Strait of Gibraltar, a system of gigantic mirrors in Earth’s orbit, or anything built under an Atoms for Peace project. In short, this is fringe engineering.

    This is also, ‘saving the world with wacky waving inflatable arm flailing tube men.’

    The idea of building tens of thousands of fabric chimneys, placing them all around the globe, and cooling the Earth while sequestering carbon dioxide is fantastic. Ideas are simple, implementation is something else entirely. There are also obvious problems with the physics presented in the Super Chimney presentation, but these problems don’t actually make a Super Chimney impossible. We need more eyes on this, so we’re opening this one up as an Ask Hackaday. What do you think of this audacious scheme, and is it even possible?

    These Are The Twenty Finalists For The Hackaday Prize Best Product 

    Hackaday is hosting the greatest hardware competition on Earth, and we’re giving away thousands of dollars to hardware creators to build the next generation of electronics. This is the Hackaday Prize, and already we’ve selected dozens of projects, one of which will win $50,000 USD.

    Like last year, this year’s Hackaday Prize is very special. We’re supporting entrepreneurs building the Next Big Thing. This is the Best Product competition of The Hackaday Prize, and these are the products that will shake up an industry.

    Now, it’s finally time to pick the finalists. These twenty projects will move onto the final round of the Best Product competition for a chance to win $30,000 USD, and an opportunity to work in the Supplyframe Design Lab, perfecting their prototype and turning it into a product.

    The Hackaday Prize Best Product finalists are, in no particular order:PewPew FeatherWing4G LTE Repeater / Booster / FemtocellInspectorBotOrthrusCity Air QualitySmart Composting SystemEMMETipo: Braille Smartphone Keypadn3m0: The Autonomous BoatFochica – Forgotten Child in Car AlertMeshPoint – wifi router for humanitarian crisisDevice for Seismic Noise AnalysisHeartyPatchBracelet for the blindBeagleLogic StandalonerDUINOScope BoianaConnected HealthOpen Source IOT PlatformZBeam – Shape Shifting Structures For SpaceZeroPhone – a Raspberry Pi smartphone

    It’s Not Over Yet

    These are the twenty finalists for the Best Product competition in this year’s Hackaday Prize, but we won’t be deciding which of these products will win until November.

    This means there’s still a lot of work left for these Best Product finalists. Like all Hackaday Prize finalists, they’ll have to produce a video, but the Best Product is special: they’ll have to build three prototypes and send them off to our panel of hardware judges to be assessed on the basis of utility, manufacturability, and market.

    All of these are spectacular projects, and for being a finalist they’ve already won $1000 USD each. There can only be one winner, and this project will win $30,000 USD, and an opportunity to spend some time in the Supplyframe Design Lab where they’ll have the tools, mentoring and the budget to turn their prototype into a real product.

    Hackaday Prize Entry: Pan And Tilt Sprinkler 

    There are a few very popular irrigation systems entered into this year’s Hackaday Prize. In fact, last year’s winner for the Best Product portion of the Prize was the Vinduino, a soil moisture monitor for vineyards. Most of these irrigation systems use drip irrigation or are otherwise relatively small-scale. What if you need something a little more powerful? That’s where
