Friday Hack Chat: Circuit Python

Back in the olden days, if you wanted to learn how to program a computer, you used the BASIC interpreter stored in ROM. This is how an entire generation of devs learned how to program. Now, home computers do not exist, there is no programming language stored in ROM, and no one should inflict JavaScript on 8-year-olds. What is the default, My First Programming Language™ today? Python. And now it’s on microcontrollers.

For this week’s Hack Chat on hackaday.io, we’re going to be talking all about Circuit Python. Circuit Python is based on the Open Source MicroPython, a Python 3 …read more http://pje.fyi/QDSYm6

Rage Against the Dying of the Light with a Raspi Night Vision Camera

One of the most interesting things about hacking is the difference between the vision we have at the beginning and the reality of we’ve built at the end. What began as a simple plan to build a night vision VR headset turned into a five-month adventure for [facelessloser] that culminated in this great-looking camera. He thought it would be easy, but almost every aspect presented some kind of challenge. The important thing is that he kept at it.

One of the major issues [facelessloser] encountered was power. He found that the Pi (Zero W), the screen, and the IR LEDs …read more http://pje.fyi/Q3fq2T

Home Brew Augmented Reality

In July of 2016 a game was released that quickly spread to every corner of the planet. Pokemon Go was an Augmented Reality game that used a smart phone’s GPS location and camera to place virtual creatures into the person’s real location. The game was praised for its creativity and was one of the most popular and profitable apps in 2016. It’s been download over 500 million times since.

Most of its users were probably unaware that they were flirting with a new and upcoming technology called Augmented Reality. A few day ago, [floz] submitted to us a blog from …read more http://pje.fyi/Q2419P

Neural Network Really Ties The Room Together

If there’s one thing that Hollywood knows about hackers, it’s that they absolutely love data visualizations. Sometimes it’s projected on a big wall (Hackers, WarGames), other times it’s gibberish until the plot says otherwise (Sneakers, The Matrix). But no matter what, it has to look cool. No hacker worth his or her salt can possibly work unless they’ve got an evolving Venn diagram or spectral waterfall running somewhere in the background.

Inspired by Hollywood portrayals, specifically one featured in Avengers: Age of Ultron, [Zack Akil] decided it was time to secure his place in the …read more http://pje.fyi/Py08Qt

Tweet The Power Of Lightning!

How quickly would you say yes to being granted the power to control lightning? Ok, since that has hitherto been impossible, what about the lesser power of detecting and tweeting any nearby lightning strikes?

Tingling at the possibility of connecting with lightning’s awesome power in one shape or another, [Hexalyse] combined AMS’s lightning sensor chip with a Raspberry Pi and a whipped up a spot of Python code to tweet the approach of a potential storm. Trusting the chip to correctly calculate strike data, [Hexalyse]’s detector only tweets at five minute intervals — because nobody likes a spambot — but …read more http://pje.fyi/PTGt8R

Australian Raspberry Pi Tutorials

There’s a new and very detailed video tutorial about the Raspberry Pi available from the Australian firm Core Electronics.  There are 30 videos and 5 chapters in total. A few of the introduction videos are short, but the detail videos range from 3 to 16 minutes.

The instructor [Michael] starts out at the very beginning — loading NOOBS on the Pi — and then moves on to Python, shell scripting, and building GUI applications with TkInter. It also covers using Particle Pi for IoT applications that integrate with IFTTT.

We do realize that most people reading Hackaday have probably used …read more http://pje.fyi/PRn7rb

Simple Wave Generation in Python (and SciPy)

[153Armstrong] did a short post on how easy it is to generate waveforms using Python. We agree it is simple, but actually, it isn’t so much Python per se, it is some pretty cool libraries (SciPy, in particular) that do all the hard work. That may be splitting hairs, but it is worth nothing that SciPy (pronounced “Sigh Pie”) also does other handy tricks like Fourier transforms, too. You can see a video of his results, below.

The code is simple and one of the commenters pointed out an even more efficient way to write the data to a …read more http://pje.fyi/PQSWz0
