Reimagining the Megalodon, the World’s Most Terrifying Sea Creature

*cues Jaws score*

via Smithsonian

When I reached the world’s pre-eminent sculptor of long-dead monsters, he was standing atop a ladder inside a 16-foot-tall section of a megalodon tail that was propped upright in his warehouse-size studio. “I’m sorry if it sounds like I’m inside a bathroom,” Gary Staab said on his cellphone. The tail was part of a 52-foot-long, life-size model of the prehistoric shark that Staab was custom-building for the Smithsonian’s National Museum of Natural History.

The mighty megalodon, terror of the ancient oceans, could grow to 60 feet long, with a mouth stretching more than 9 feet wide and a bite-force stronger than any other creature ever, living or dead. The violent damage it caused to its prey, and the rows of serrated teeth, have given the shark the reputation of an enormous prehistoric Jaws—“a great white on steroids,” says Hans Sues, chair of paleobiology at the museum.

How to Add a Power Button to Your Raspberry Pi #piday #raspberrypi @Raspberry_Pi

Via Make Use Of:

It might be a fantastic, flexible little computer, but the Raspberry Pi has one key flaw: the lack of a power button. Missing a standard on/off switch can lead to problems; thankfully, you can add your own Raspberry Pi power button.

Two choices are available: a DIY power button, or one you purchase. Let’s look at how to add a power button to your Raspberry Pi and guarantee a safe, orderly shutdown.

Build a Car Computer with Raspberry Pi #piday #raspberrypi @Raspberry_Pi

via The MagPi Magazine

One of the ultimate mods for modern cars is to replace or upgrade the entertainment system. This can range from something as small as adding new speakers, to replacing the stock stereo, or – in our case – creating a custom computer purpose-built for your car.

The Raspberry Pi is fantastic for this task. It’s small enough that it’s easy to hide, and powerful enough to handle simple telemetry, dash-cam recording, GPS, and more. Thanks to AutoPi, you won’t need to be deep in the bowels of your car snipping wires, either, and you can control it using a cloud-based service. Let’s make your car futuristic!

Your next flexible PCB chip might be connected via springs #PCB #EE #Manufacturing @whitequark

CCGA Spring Chip Connect Semiconductor

Connecting a large chip to a flexible PCB? CCGA are interconnects made of lots of tiny springs or columns instead of the solder balls or pads traditionally used. The spring technology was developed by NASA presumably for space flight.

The chips may be attached via a vapor phase reflow oven or 12-zone convection oven.

Twitter user @whitequark has a thread discussing these interesting chips and interconnect technologies.

TopLine has a tool set for working with such chips. TopLine also has a discussion of other column type interconnects including plain columna, columns with copper wrap, and copper braided columns. See this page for the details on using spring interconnects.

What’s your next flexible interconnect technology? Let us know in the comments below.

Indoor Air Quality and Garbage Monitoring System #piday #raspberrypi @Raspberry_Pi

via hackster.io

Building automation is the automatic centralized control of a building’s heating, ventilation and air conditioning, lighting and other systems through a building management system or building automation system (BAS). The objectives of building automation are improved occupant comfort, efficient operation of building systems, reduction in energy consumption and operating costs, and improved life cycle of utilities.

Building automation is an example of a distributed control system – the computer networking of electronic devices designed to monitor and control the mechanical, security, fire and flood safety, lighting, HVAC and humidity control and ventilation systems in a building.

This tutorial will walk you through the process of wiring the ADXL345 to your Raspberry Pi. It also goes through the steps on how to implement Adafruit’s ADXL34x library to talk with the device. Both are relatively simple processes.

The ADXL345 is a low power, 3-axis (It tracks both X, Y and Z accelerations) MEMS accelerometer that utilizes the I2C and SPI serial interfaces.

Motion Controlled Water Fountain for a Cat @Raspberry_Pi #PiDay #RaspberryPi

from vladimirm  via hackster.io

A quick way to control a water fountain for a cat only when the cat is nearby using BigClown and Home Assistant.

When PIR sensor detects movement it sends message to Radio Dongle plugged to the Raspberry Pi which sends the message to the MQTT server. On the other side MQTT message is processed by the Home Assistant which then using the automation triggers smart plug and starts configured countdown.

Raspberry Pi3 IR Camera Wide-angle waterproof housing #3DPrinting #3DThursday

bujna94 shared this project on Thingiverse!

Hi, I designed this housing for:

MakerHawk Raspberry Pi3 Camera IR Fisheye Wide-angle 175 Degree 5MP OV5647.

Link to Amazon – https://amzn.to/2G10jXE

I was printing it with PETG 100% infill, but PLA or ABS will be fine too. (PLA is not recommended for outdoor use). Gaskets I print with TPU 100% infill again.

My printer is Ender 3 & layer height was 0.3mm.

The reason why the camera lens is not covered with plexiglass is night vision. If I just cover the whole camera with plexiglass, IR lights will reflect and you will be not able to see almost anything.

Spherez storage containers #3DThursday #3DPrinting

Shared by muzz64 on Thingiverse:

Spherez are cool little storage container for small things that are unique and visually interesting. The outer shell rotates freely 360° to open and close the opening into the centre storage section. A simple, fun and practical storage solution for anything and everything from coins to jewellery, nuts/bolts/screws, keys, stationery items and much more. Great to use yourself or as a small ‘unique’ gift. And, they look good printed in any color.

This is and easy and worthwhile one-piece-print that takes a while to print…. the Spherez outside diameter at standard scale is 80mm. The internal storage area has a diameter of approx. 72mm. This can be scaled up or down a small amount if required however and scaling will affect clearances that may affect the result (parts fusing or being too loose).

The design also features a circular groove in the base. This will accept and retain a common small 3mm square section rubber band so the print is far less likely to move around on the surface it is being used on. The rubber band creates a degree of surface tension / grip so it will not slide so easily. This is very handy as it enables users to rotate the outer shell (with a small amount or downward force) without the need to hold the base part which may otherwise also want to rotate to some extent.
