Hackaday Prize 2023: OMOTE Universal Remote

July 15, 2023 by 39 Comments

A good universal remote can help tame today’s complex home entertainment systems, combining both classic IR and more modern WiFi and Bluetooth connectivity with programmable functions that allow the user to execute multi-step operations with a single button. Unfortunately, programming them often involves the use of clunky proprietary software.

Which is why [Maximilian Kern] has developed the OMOTE. This open source universal remote is powered by the ESP32, and features the usual collection of physical buttons in addition to a 2.8” 320 x 240 touchscreen with a responsive graphical interface that can display more advanced user interfaces. Everything is packed into an ergonomic 3D printed case that gives it an exceptionally professional look.

The remote’s USB-C port can be used to recharge the internal 2,000 mAhA battery, as well as reprogram the ESP32’s firmware via a CH340C serial chip. The battery life is estimated to be about six months given the considerable low-power capabilities of the ESP32, which includes the use of a LIS3DH 3-axis accelerometer to keep the hardware in sleep mode until it’s picked up.

The software side is still in development, so the IR codes for the remote are currently hardcoded and its WiFi capabilities are limited to MQTT. But in the future, [Maximilian] imagines a web-based configuration interface that runs on the ESP32 and lets you add codes and setup the remote via your phone or desktop.

It looks like the hardware is more or less complete, so presumably the focus from here on out will be bringing the software across the finish line. Don’t worry, there’s still plenty of time — since it’s an entry into the Gearing Up challenge of the 2023 Hackaday Prize, the judges won’t pick the finalists until August 8th.

Gearing Up With The 2023 Hackaday Prize

July 5, 2023 by 3 Comments

You know how it goes. You’re working on a project, and you need to do some ultra-precise probing, so you end up making a custom PCB probing octopus along the way. Or you find that you spend more time making the jig to hold down a part for machining than you do machining it. Hackers are not merely a tool-using species, we’re a tool-making species – it’s in our nature to want to build the tools that make it easier to get the job done.

The Gearing Up round of the Hackaday Prize celebrates the tool makers. If you’ve got a project that maybe isn’t an end in itself, but rather one of those utility project that can make all the difference, we want to see it here. Maybe it’s obscure measurement gear, maybe it’s a test rig or a bolt sorter, maybe you’ve built your own reflow hot plate. This is the challenge round for you!

The Gearing Up round runs from yesterday, July 4th, until August 8th. As with all of the 2023 Hackaday Prize rounds, ten finalists will receive $500 and get entered for the big prizes to be announced in November. Continue reading “Gearing Up With The 2023 Hackaday Prize” →

Hackaday Links: June 25, 2023

June 25, 2023 by 15 Comments

Is it really a dystopian future if the robots are radio-controlled? That’s what came to mind reading this article on a police robot out of Singapore, complete with a breathless headline invoking Black Mirror, which is now apparently the standard by which all dystopias are to be judged. Granted, the episode with the robo-dogs was pretty terrifying, but it seems like the Singapore Police Force has a way to go before getting to that level. The bot, which has been fielded at Changi Airport after extensive testing and seems to be completely remote-controlled, is little more than a beefy telepresence robot. At 5.5 feet (1.7 meters) tall, the bot isn’t terribly imposing, although it apparently has a mast that can be jacked up another couple of feet, plus there are lights, sirens, and speakers that can get the message across. Plus cameras, of course; there are always cameras. The idea is to provide extra eyes to supplement foot patrols, plus the potential to cordon off an incident until meatspace officers arrive. The buzzword game here is weak, though; there’s no mention of AI or machine learning at all. We have a feeling that when the robots finally rise up, ones like this will be left serving the drinks.

Hackaday Prize 2023: This Challenge Makes It So Easy Being Green

May 31, 2023 by 2 Comments

This year’s Hackaday Prize is our first nice round number – number ten! We thought it would be great to look back on the history of the Prize and cherry-pick our favorite themes from the past. Last year’s entire theme was sustainable hacking, and we challenged you to come up with ways to generate or save power, keep existing gear out of the landfill, find clever ways to encourage recycling or build devices to monitor the environment and keep communities safer during weather disasters, and you all came through. Now we’re asking you to do it again.

There are hundreds of ways that we can all go a little bit lighter on this planet, and our Green Hacks Challenge encourages you to make them real. Whether you want to focus on clean energy, smarter recycling, preventing waste, or even cleaning up the messes that we leave behind, every drop of oil left unburned or gadget kept out of the landfill helps keep our world running a little cleaner. Here’s your chance to hack for the planet.

Inspiration

One thing we really loved about last year’s Green Hacks was that it encouraged people to think outside the box. For instance, we got some solar power projects as you’d expect, but we also got a few really interesting wind power entries, ranging from the superbly polished 3D Printed Portable Wind Turbine that won the Grand Prize to the experimental kite turbine in Energy Independence While Travelling, to say nothing of the offbeat research project toward making a Moss Microbial Fuel Cell.

Plastic was also in the air last year, as we saw a number of projects to reuse and recycle this abundant element of our waste stream. From a Plastic Scanner that uses simple spectroscopy to determine what type of plastic you’re looking at, to filament recyclers and trash-based 3D printers to make use of shredded plastic chips.

Finally, you all really put the science into citizen science with projects like OpenDendrometer that helps monitor a single tree’s health, and the Crop Water Stress Sensor that does the same for a whole field. Bees didn’t get left out of the data collection party either, with the Beehive Monitoring and Tracking project. And [Andrew Thaler]’s tremendously practical Ocean Sensing for Everyone: The OpenCTD brought the basics of oceanic environmental monitoring down to an affordable level.

Now It’s Your Turn to be Green

If any of the above resonates with your project goals, it’s time to put them into action! Start up a new project over on Hackaday.io, enter it into the Prize, and you’re on your way. Ten finalists will receive $500 and be eligible to win the Grand Prizes ranging from $5,000 to $50,000. But you’ve only got until Tuesday, July 4th to enter, so don’t sleep.

As always, we’d like to thank our sponsors in the Hackaday Prize, Supplyframe and DigiKey, but we’d also like to thank Protolabs for sponsoring the Green Hacks challenge specifically, and for donating a $5,000 manufacturing grant for one finalist. Maybe that could be you?

Hackaday Prize 2023: The Assistive Tech Challenge Starts Now

April 26, 2023 by 1 Comment

We’d all love to change the world and make it a better place, but let’s be honest…that’s a pretty tall order. Even the best of ideas, implemented perfectly, can only do so much globally. But that doesn’t mean the individual can’t make a difference — you just need to think on a different scale. If improving everyone’s life is a bit out of reach, why not settle for a smaller group? Or perhaps even just one person?

That’s precisely what we’re looking for in the Assistive Tech Challenge of the 2023 Hackaday Prize. In this Challenge, we’re asking the community to come up with ideas to help those with disabilities live fuller and more comfortable lives.

Whether you help develop an improved prosthesis that could benefit thousands, or design a bespoke communication device that gives a voice to just a single individual, it’s hard to imagine a more noble way to put your skills and knowledge to use.

Looking to lend a hand? You’ve got from now until May 30th to enter your Assistive Tech project. It doesn’t matter what kind of impairment it focuses on — so long as it helps somebody work, learn, or play, it’s fair game to us.

The ten finalists for this Challenge will be announced around June 12th, but you’ll have to wait until Hackaday Supercon in November to find out which projects take home their share of the more than $100,000 in cash prizes graciously provided by sponsors Digi-Key and SupplyFrame.

2022 Hackaday Prize: Congratulations To The Winners Of The Climate-Resilient Communities Challenge

September 28, 2022 by 1 Comment

Holy humanitarian hacking, Batman! We asked you to come up with your best climate-forward ideas, and you knocked it out of the ionosphere! Once again, the judges had a hard time narrowing down the field to just ten winners, but they ultimately pulled it off — and here are the prize-winning projects without much further ado.

In the Climate-Resilient Challenge, we asked you to design devices that help build communities’ resilience to severe weather and the increasing frequency of natural disasters due to climate change, and/or devices that collect environmental data that serves as hard evidence in the fight for changes in local infrastructure. While several people focused on air quality, which is something we tend to think of as a human need, plenty others thought of the flora and fauna with which we share this planet.
