The average motorist has a lot to keep track of these days. Whether its how much fuel is left in the tank, how much charge is left in the battery, or whether or not the cop behind noticed them checking Twitter, there’s a lot on a driver’s mind. One thing they’re not thinking about is […]
We’ve seen plenty of plywood 3D printers before; after all, many early hobbyist machines were made from laser-cut plywood. But this plywood 3D-printer isn’t made from plywood – it prints plywood. Well, sort of. Yes, we know – that’s not plywood the printer is using, but rather particleboard, the same material that fills the flatpack […]
If you read Hackaday, it is a good bit you’ve heard of MQTT — Message Queueing Telemetry Transport. If you’ve not used MQTT before, you should check out Ably’s [Kayla Matthews’] post entitled MQTT: A Conceptual Deep Dive paper. She does mention their MQTT protocol connector at the end, and has a few notes about […]
There’s something about Frequency Modulation (FM) synthesizer chips that appeals to a large audience. That’s one of the reasons behind [René Ceballos]’s XFM project, aiming to duplicate on an FPGA the sound of pure-FM synthesizer chips of the past such as the Yamaha DX series, OPL chip series and TX81Z/802/816. The result is a polyphonic, […]
In the movie Wall-E, future humans live in floating chairs and have everything done for them. Today, we grumble if we have to go to physically find a light switch or a remote control. How far away can floating chairs with screens be? T2, the Tea Bot, gets us one step closer to that. Using […]
In many sports, it’s important for competitors to be light on their feet, and able to react quickly to external stimuli. It all helps with getting balls in goals, and many athletes undergo reaction drills as part of their training regime. To help with this, [mblaz] set out to build a set of reaction trainers. […]
There’s nothing quite as relaxing as a long, hot shower. This has the tendency of making the bather absent minded as to the amount of water being used, which can lead to excessive bills. [LiamOSM] built a device to monitor this instead, and calculate the cost, to boot. The device consists of an Arduino hooked […]
No it’s not an open source version of Bert’s favorite bathtime toy (though seriously, let us know if you see one), the PocketAdmin by [Radik Bechmetov] is intended to be an alternative to the well-known “USB Rubber Ducky” penetration testing tool from Hak5. It might look like a standard USB flash drive, but underneath that […]
Even a relatively low-end desktop 3D printer will have no problems running off custom enclosures or parts for your latest project, and for many, that’s more than worth the cost of admission. But if you’re willing to put in the time and effort to become proficient with necessary CAD tools, even a basic 3D printer […]
Fans of Ghostbusters will remember the PKE meter, a winged handheld device capable of detecting supernatural activity. Precious little technical data on the device remains, leaving us unable to replicate its functionality. However, the flashing, spreading wings serve as a strong visual indicator of danger, and [mosivers] decided this would be perfect for a Geiger counter […]
