Fly a Pi On Your Next Model Rocket
https://hackaday.com/2019/07/05/fly-a-pi-on-your-next-model-rocket/

From time to time, we see electronics projects for model rocket instrumentation. Those who have been involved in the hobby for many years may remember when 8-bit microcontrollers like the PIC16F84 were the kind of hardware you might fly on a mission. These days, however, there’s little reason not to …read more (https://hackaday.com/2019/07/05/fly-a-pi-on-your-next-model-rocket/)
Building A Smart Speaker From Scratch
https://hackaday.com/2019/07/05/building-a-smart-speaker-from-scratch/

Smart speakers have proliferated since their initial launch earlier this decade. The devices combine voice recognition and assistant functionality with a foreboding sense that paying corporations for the privilege of having your conversations eavesdropped upon could come back to bite one day. For this reason, [Yihui] is attempting to build …read more (https://hackaday.com/2019/07/05/building-a-smart-speaker-from-scratch/)
How To Turn A Chainsaw Into A Chopsaw
https://hackaday.com/2019/07/05/how-to-turn-a-chainsaw-into-a-chopsaw/

If you’re doing a lot of metal working, a chop saw is a great tool to have. It’s an easy and quick way to do a lot of neat, clean accurate cuts. [Making Stuff] wanted to do just that, but didn’t have a chop saw lying around. Instead, an old …read more (https://hackaday.com/2019/07/05/how-to-turn-a-chainsaw-into-a-chopsaw/)
Bringing FPGA Development To The Masses
https://hackaday.com/2019/07/05/bringing-fpga-development-to-the-masses/

The Field Programmable Gate Array (FPGA) is one of the most exciting tools in the modern hacker’s arsenal. If you can master the FPGA, you can create hardware devices that not only morph and change based on your current needs, but can power through repetitive tasks at phenomenal rates. The …read more (https://hackaday.com/2019/07/05/bringing-fpga-development-to-the-masses/)
An Arduino Sickbay Display Worthy Of The Enterprise
https://hackaday.com/2019/07/05/an-arduino-sickbay-display-worthy-of-the-enterprise/

The various displays and interfaces in Star Trek, especially The Original Series, were intentionally designed to be obtuse and overly complex so they would appear futuristic to the audience. If you can figure out how Sulu was able to fly the Enterprise with an array of unlabeled buttons and …read more (https://hackaday.com/2019/07/05/an-arduino-sickbay-display-worthy-of-the-enterprise/)
Safely Measuring Single And Three-Phase Power
https://hackaday.com/2019/07/06/safely-measuring-single-and-three-phase-power/

There are many reasons why one would want to measure voltage and current in a project, some applications requiring one to measure mains and even three-phase voltage to analyze the characteristics of a device under test, or in a production environment. This led [Michael Klopfer] at the University of California, …read more (https://hackaday.com/2019/07/06/safely-measuring-single-and-three-phase-power/)

https://hackaday.com/2019/07/06/this-chiptune-players-got-what-nintendont/

When it comes to chiptunes, the original Nintendo Entertainment System and the Game Boy get all the accolades. The OPL synths have all the fun. But there’s another chip out there in dusty old machines that is at least as interesting with a repertoire at least as influential as the …read more (https://hackaday.com/2019/07/06/this-chiptune-players-got-what-nintendont/)
3D Printed Buttons, Printed as a Single Unit
https://hackaday.com/2019/07/06/3d-printed-buttons-printed-as-a-single-unit/

These nifty buttons come from [Marc Schömann], and they are intended to cover just about any kind of tact switches. The buttons, their cover, and the compliant bits that act as a spring can be 3D printed as a complete unit that requires no assembly, and can be used fresh …read more (https://hackaday.com/2019/07/06/3d-printed-buttons-printed-as-a-single-unit/)
Guitar Made from Noodles Glows in the Dark
https://hackaday.com/2019/07/06/guitar-made-from-noodles-glows-in-the-dark/

Wood.  Specifically, certain types of tone woods; woods that impart a certain tone. That’s what guitars are made of. And occasionally, plastic, or metal, or fibreglass or, well, anything. [_forwardaudio_] built his out of noodles, because, why not?
Well, not completely out of noodles. Epoxy is used to give some …read more (https://hackaday.com/2019/07/06/guitar-made-from-noodles-glows-in-the-dark/)
Phase Shift Pump Control? There’s an App for That.
https://hackaday.com/2019/07/06/phase-shift-pump-control-theres-an-app-for-that/

The sort of pumps used in the filtration systems of fountains and swimming pools don’t take kindly to running dry. So putting such a pump on a simple timer to run while you’re away comes with a certain level of risk: if the pump runs out of water while you’re …read more (https://hackaday.com/2019/07/06/phase-shift-pump-control-theres-an-app-for-that/)
Earthquake Detection on a Chip
https://hackaday.com/2019/07/06/earthquake-detection-on-a-chip/

If you’ve ever been in an earthquake you’d assume it would be pretty easy to detect one. If things are shaking, there’s an earthquake. In reality, though, a lot of things can shake a sensitive instrument that is detecting shaking, so — for example — mechanical sensors will produce a …read more (https://hackaday.com/2019/07/06/earthquake-detection-on-a-chip/)
