Electronic door lock install DIY!

Here is how I added an electronic keypad and lock to one of doors. I did this after locking my keys accidentally in the room. Keypad and hole in the wall. I used a back-lit enforcer keypad. You can use any Keypad. They are all basically the same. Power wires, door unlock and then an output pair...By: MjtrinihobbyContinue Reading »


Accessible Makey Makey - Puzzle

This is a puzzle game focused on visually impaired people as end users. Each piece has a different pattern of copper tape on it that will only complete the circuit and thus give a sound response when placed in the correct location. In this prototype, we assigned each piece a letter and programmed ...By: MadhumithaSContinue Reading »


Pinball Simulator Makes The Neighbors Happy

There are a lot of simulators out there if you want to try something out that would be otherwise impossible. Great examples are flight simulators for simulating the piloting of a fighter jet, or goat simulators for simulating the life of a goat who destroys a town. [Erland] wanted a pinball machine, but like planes and goats, found it was impractical to get a real one because it would probably upset his neighbors in his apartment. Instead, he set out to build a pinball simulator.

The cabinet is miniature-sized compared to a regular pinball machine so it can more easily ¦read more



Hackaday Prize Entry: A Better KVM Switch

Now it™s not uncommon to have a desktop and a laptop at a battlestation with tablets waiting in the wings. Add in a few Raspis, consoles, and various cheap computers, and it™s pretty easy to have an enormous number of machines and monitors on a desk. Traditionally, a KVM switch would be the solution to this, sharing a keyboard, mouse, and monitor with many different boxes, but this is an ugly solution. [frankstripod] has a device that fixes that with some interesting software and a few USB hacks.

[frankstripod] is in love with a program called Synergy this program combines ¦read more



Bitten By PCB Defects

If you™ve ordered PCBs from Seeed Studio, ITead, DirtyPCB, or another board house in China, you™ve probably noticed that neat little 100% e-test option available on the order form. If you select this, the board house will throw your PCBs in a machine that will poke a pin in every pad to make sure all the connections are good. Less work for you, right? As [Andy] found out, not always. He was bitten by a manufacturing defect that sheds some light on what that e-test actually is, and the capabilities of what these Chinese board houses can do.

Geometrical Symmetry In Nature #Biomimicry

Photos of geometrical plants for symmetry lovers! Above is Aloe Polyphylla via bored panda Who said math can™t be interesting? Fractals like these can seem too perfect to be true, but they occur in nature and plants all the time and are examples of math, physics, and natural selection at work! When we see order [¦]


Assembling an Avengers: Age of Ultron Scarlet Witch Costume

Avengers: Age of Ultron premiered last weekend, and the Marvel film introduced Quicksilver and Scarlet Witch, also known as Pietro and Wanda Maximoff. Their costumes were quite different from what we™ve seen in comic books, but in this case, I™m glad about the change. They both wear more everyday sort of attire rather than theatrical [¦]


Open Source “ Non-Invasive Glucose Meter Project #WearableWednesday

Useful project for glucose monitoring for folks with diabetes. Via idlehandsproject.com. I™m sure we are all now aware of the rapidly increasing epidemic that is Diabetes.

These Haptic VR Gloves Don’t Buzz #WearableWednesday

Any time I™ve seen something haptic, it™s always relied on a buzzing motor. That isn™t a bad thing, but it™s nice to see this fresh glove in Popular Science. A team of engineers at Rice University created HandsOmni to answer the challenge of non-vibration tactile finger feedback. Their hope is the glove can be used as part [¦]


Wearable banana – Dole presents the world’s first edible wearable #WearableWednesday

Weather Beacon

As my son has gotten older he's become very interested in weather and how the earth works. He's only 3 and does not know how to read but gets a lot of information from pictures, sounds and color. To help him understand some of the basic concepts of our planet like the moon, high tide, low tide, th...By: allmackeyContinue Reading »


[Kenji Larsen] Shows off the Ultimate Hacking Kit

If you roll into a hardware hackathon empty-handed, you™re going to be at a disadvantage compared to those who bring equipment with which they™re already familiar. Pray that you never roll into one where [Kenji Larsen] is your competitor. Luckily, this weekend he came out to mentor for Hackaday™s hardware hacking village at the TechCrunch Disrupt hackathon and not as a competitor. In this video he shows off the huge rollerbag which he calls his śHack Packť. I™d say there™s a 50/50 chance his travel setup is better than your home lab.

Where do I begin (seriously, watch the video)?  ¦read more



Retrotechtacular: The Spirit of Radio

Many of us still tune in to terrestrial radio for one reason or another, be it baseball games, talk radio, or classic rock. But do you know how the sound is transmitted to your receiver? This week, our spotlight shines upon a short film produced by KYW Radio that serves as a cheerful introduction to the mysteries of amplitude modulation (AM) radio transmission as they were in 1940.

Sound vibrations enter a microphone and are converted to electrical current, or an audio waveform. The wave is amplified and sent several miles away to the transmitting station. During this trip, the ¦read more



TechCrunch Disrupt: Charging A Phone With Its Own Transmitter

TechCrunch Disrupt is on this week, and that means we get to see which members of tech media don™t understand basic physics. So far, it™s writers from Engadget, The Mirror, Business Insider, TechCrunch, and four judges on the TC Disrupt stage. What is the consequence of not understanding the implications of the conservation of energy? Glowing support for a cell phone that can charge itself.

The offending Disrupt startup is Nikola Labs, and they™re gearing up to launch a Kickstarter for a very special iPhone 6 case. This case uses small, energy-harvesting antennas to gather RF energy from the cellphone ¦read more

LED Parachute Tutorial #makereducation

We love this project tutorial from the Children™s Museum of Houston on instructables! Create an unidentified floating object! This is a great activity not only on simple circuits, but also on air resistance/drag and aerodynamics. Also easily folds up into the pocket like the parachute people toys, only a lot easier to find at night! [¦]
