What We Need To Try In Haptic HacksHaptX haptic VR glovestevendufInflatable bladders for touch

Thu, 22 Mar 2018 08:00:00 +0000

Looking for ideas for your haptics projects? [Destin] of the Smarter Every Day YouTube channel got a tour from the engineers at HaptX of their full-featured VR glove with amazing haptic feedback both with a very fine, 120-point sense of touch, force feedback for each finger, temperature, and motion tracking.

In hacks, we usually stimulate the sense of touch by vibrating something against the skin. With this glove, they use pneumatics to press against the skin. A single fingertip has multiple roughly 1/8 inch air bladders in contact with it. Each bladder is separately pneumatically controlled by pushing air into …read more

3D Printed Raspberry Pi NAS with Dual Drive Bays3dnas_feattomnardi

Thu, 22 Mar 2018 05:00:09 +0000

While it might not pack the computational punch you’d usually be looking for in a server platform, you can’t beat how cheap the Raspberry Pi is. As such, it’s at the heart of many a home LAN, serving up files as a network attached storage (NAS) device. But the biggest problem with using the Pi in a NAS is that it doesn’t have any onboard hard drive interface, forcing you to use USB. Not only is this much slower, but doesn’t leave you a lot of options for cleanly hooking up your drives.

This 3D printable NAS enclosure designed by …read more

Bring Deep Learning Algorithms To Your Security Camerascam-featadamfabio

Thu, 22 Mar 2018 02:00:53 +0000

AI is quickly revolutionizing the security camera industry. Several manufacturers sell cameras which use deep learning to detect cars, people, and other events. These smart cameras are generally expensive though, compared to their “dumb” counterparts. [Martin] was able to bring these detection features to a standard camera with a Raspberry Pi, and a bit of ingenuity.

[Martin’s] goal was to capture events of interest, such as a person on screen, or a car in the driveway. The data for the events would then be published to an MQTT topic, along with some metadata such as confidence level. OpenCV is generally …read more

Look Upon Eyepot, And Weep For Mercyeyepot_feattomnardi

Wed, 21 Mar 2018 23:00:20 +0000

Hope you weren’t looking forward to a night of sleep untroubled by nightmares. Doing his part to make sure  Lovecraftian mechanized horrors have lease in your subconscious, [Paul-Louis Ageneau] has recently unleashed the horror that is Eyepot upon an unsuspecting world. This Cycloptic four legged robotic teapot takes inspiration from an enemy in the game Alice: Madness Returns, and seems to exist for no reason other than to creep people out.

Even if you aren’t physically manifesting nightmares, there’s plenty to learn from this project. [Paul-Louis Ageneau] has done a fantastic job of documenting the build, from the OpenSCAD-designed …read more

Neon Lamps Make For The Coolest Of Nixie Clocksnixie-featbodgewiresneonclock

Wed, 21 Mar 2018 20:00:19 +0000

Revisiting old projects is always fun and this Nixie Clock by [pa3fwm] is just a classic. Instead of using transistors or microcontrollers, it uses neon lamps to clock and drive the Nixie Displays. The neon lamps themselves are the logic elements. Seriously, this masterpiece just oozes geekiness.

Inspired by the book “Electronic Counting Circuits” by J.B. Dance(ZIP), published in 1967, we covered the initial build a few years back. The fundamental concept of operation is similar to that of Neon Ring Counters. [Luc Small] has a write-up explaining the construction of such a device and some math associated with it. …read more

Everyone Needs A Personal SupercomputerSupercompheaderbrianbenchoff

Wed, 21 Mar 2018 18:30:04 +0000

When you think of supercomputers, visions of big boxes and blinkenlights filling server rooms immediately appear. Since the 90s or thereabouts, these supercomputers have been clusters of computers, all working together on a single problem. For the last twenty years, people have been building their own ‘supercomputers’ in their homes, and now we have cheap ARM single board computers to play with. What does this mean? Personal supercomputers. That’s what [Jason] is building for his entry to the Hackaday Prize.

The goal of [Jason]’s project isn’t to break into the Top 500, and it’s doubtful it’ll be more powerful than …read more

Making Pictures Worth 1000 Words in Pythonpil_outtomnardi

Wed, 21 Mar 2018 17:01:43 +0000

In a previous post, I showed how you could upload images into a Discord server from Python; leveraging the popular chat platform to simplify things like remote monitoring and push notifications on mobile devices. As an example, I showed an automatically generated image containing the statistics for my Battlefield 1 platoon which gets pushed to member’s devices on a weekly basis.

The generation of that image was outside the scope of the original post, but I think it’s a technique worth discussing on its own. After all, they say that a picture is worth 1000 words. So that means a …read more
