See how we built it, including our materials, code, and supplemental instructions, on Hackster.io: https://www.hackster.io/hackershack/s…
In this video, we show you how to make a smartphone-controlled, internet-connected deadbolt actuator powered by a Raspberry Pi that can be added onto your existing door lock without any modifications to the door.
The door lock can be controlled by multiple smartphones, and even notify you whenever someone locks/unlocks the door. All of this is done using a simple, drag-and-drop app builder (http://www.blynk.cc/) which makes building your own Internet of Things (IoT) app easier than ever. For an extra impressive door lock, we’ll also show you how to add a simple LED light to indicate if the door is locked, and a push-button to operate the lock manually.

How to Set Up TensorFlow Object Detection on the Raspberry Pi
Learn how to install TensorFlow and set up the TensorFlow Object Detection API on your Raspberry Pi! These instructions will allow you to detect objects in live video streams from your Picamera or USB webcam.
How to Overclock Raspberry Pi 4 To 2.0Ghz! All 4 Cores – With Benchmarks
Warning Follow this tutorial at your own risk! The Raspberry Pi 4 can now be overclocked to 2GHZ on all 4 cores! Its only a 500Mhz overclock but it actually a really nice performance boost for the pi4 and its the highest clocks I’ve ever seen on any Raspberry Pi!
So in this video, I show you how to overclock the Pi 4 up to 2.0Ghz and I also run some benchmarks and test’s to show you how much perforce we gained with this new Overclock on the Raspberry Pi 4.

Is the Raspberry Pi 4 really that bad? Using the Rasperry Pi 4 for 3D Printing.
The Raspberry Pi 4 is out! If you’ve read the first impressions, you always hear about overheating and USB issues – but is it really that big of a deal? I test the Raspberry Pi 4 against the Raspberry Pi 3 Model B and against the very first Raspberry Pi and the results are stunning to say the least.
CORRECTION: The Choetech USB cable only worked with the Huawei supply, not the Anker one.
The Giant Board — Linux on a Feather
The Giant Board is a single-board computer running Linux crammed into an Adafruit Feather form factor. I’ve been waiting for this one since September last year. However it now looks like the board is almost here, with the first hand-built boards ready to go out to early adopters really soon.
Turning Smashed TVs into Realistic Artificial Daylight
In this video I’ll be showing you how to take old/smashed TVs and computer monitors and turn them into realistic artificial window lights, so that you can have accurate daylight illumination at any time of day.
This is all possible because of the technology used inside the backlight mechanism, as I explain in the video. Enjoy!
Teensy 4.0 Brings 600 MHz Cortex-M7 to the Arduino World
Teensy 4.0 is an Arduino-compatible board with an Arm Cortex-M7 running at 600 MHz. That is right. Six. Hundred. Megahertz. Today, Paul Stoffregen and the PJRC team adds its newest member to the Teensy product family. At $20, the Teensy 4.0 may be the best performance per dollar board available.
Raspberry Pi Zero W for BT Car Audio Streaming
Car audio capabilities can be an interesting animal. Sami Pietikäinen’s vehicle in particular came with a built-in Bluetooth setup for hands-free phone use that does not support audio streaming. Fortunately, it did come with a 3.5mm line-in jack, meaning with a bit of hacking, streaming audio from his phone over Bluetooth would definitely be possible.
Intel teases next-gen 56C/112T CPUs for 2020 still on 14nm
On the eve of AMD’s launch of its EPYC Rome CPUs, competitor Intel has announced that its future Intel Xeon Cooper Lake family of CPUs will have server versions with up to 56C/112T of power.
Intel detailed the future of its Xeon Scalable platform at its Data-Centric Innovation Summit that it’s bringing its 56C/112T Xeon Platinum 9200 family to Cooper Lake. The reason? For the new bfloat16 instructions mixed with the high 28-core count CPU as well as the new Cooper Lake CPUs being socketed versus BGA only.
Connect Apple’s Retina Displays to a Single-Board Computer Using an eDP Adapter
German tinkerer Arthur Jordan found a way to connect Apple’s outstanding retina displays from the iPad 3 and 4 to any device outfitted with an eDP (Embedded DisplayPort), such as single board computers. Those 9.7-inch retina displays feature a resolution of 2048 x 1536 (2K) and can be repurposed from bricked or damaged systems that are no longer of use or bought online for about $40 to $60.
