Mega IIe: First Fully Functional Computer Built Around the Apple Mega-II Chip element14 presents 2023-11-24 | We hope you enjoy this summary of James saga around the Apple II - from his first boot-up of a single chip Apple II (youtube.com/watch?v=vKhUGuODqOM) to this fully functional computer. James undertakes this groundbreaking project in retro computing, focusing on the Mega-II chip from a 1991 Apple IIGS. Through meticulous debugging, he evolves the project to a fully functional Mega IIe computer. This was possible due to the use of a modular hardware development platform, USB keyboard integration using RP2040, Slotmaker for control, advanced video output with another RP2040 and PicoVGA, and of course "much, much more!" Schematics and more antics are available here: bit.ly/46vMGJ4Have an idea for a build?

Edge-lit 7-Segment Display Clock Using Raspberry Pi Pico element14 presents 2024-05-10 | In Episode 600 becon_dave on the community site commented that along with the cuckoo clock, a miniature 3D diorama scene could be added (like a traditional cuckoo clock), and suggested that a edge-lit multi-layered laser engraved scene could be used. So, in this episode of Element14 Presents, Katie introduces us to her latest project: creating an acrylic edge-lit clock.The inspiration stemmed from discussions in the community about edge-lit dioramas, sparking Katie's interest in utilizing a laser cutter for this endeavor. Beginning with a simple etched acrylic design, she outlines her vision for illuminating each number on the clock face. Katie experiments with edge-lit laser engraved acrylic by making a clock with a Raspberry Pi Pico, but ensure that it could be a platform that can be changed in the future, so maybe one day we’ll see a scene!Check out the full episode blog on the #element14Community: bit.ly/3JUlVVF#0:00 Welcome to element14 presents#0:18 Overview#1:18 The Plan#4:33 The Schematic And Design#10:22 Assembly#13:58 Time To Test!#15:27 Give your Feedback#homeautomation #raspberrypi #arduinoproject #smartroom #tutorial Engage with the element14 presents team on the element14 Community - suggest builds, find project files and behind the scenes video: bit.ly/3tmdewvVisit the element14 Community for more great activities and free hardware:Tech spotlights: bit.ly/3qPrDhMRoadTest and Reviews: bit.ly/3pV5BuxProject14: bit.ly/31wbnJY

Practical DIY Pi Pico Current Load Circuits element14 presents 2024-03-08 | For whatever electronics projects you’re doing, one thing is for sure, you need to power it somehow. It can be anything from being directly connected to the outlet, a battery, a buck converter, a linear regulator and so on. When you think about testing a power supply, the first thing you think about is measuring its output voltage. Another important thing that should be tested is how that power supply performs under a load, whether that’s a battery or a buck converter.

Custom RP2040 PCB: Design, Turn-On, and Debug - How Hard Could It Be? element14 presents 2024-01-19 | James originally intended to make a video about a tool that he calls a "State Mode Logic Analyzer." One of the core components of that project is the RP2040 microcontroller from Raspberry Pi and its programmable IO (PIO) modules.However, getting the RP2040s to work on the custom-made PCBs that James designed turned out to be a chore. So, for this episode, he shares soldering RP2040 (QFN) techniques, easy-to-solder parts for RP2040 designs, and what to debug when turning on custom microcontroller boards. After all, how hard could it be to make a custom RP2040 PCB?Discuss the episode, questions James's design choices, and ask him questions on the element14 Community! bit.ly/3HqKMz6Article: The Myth of Three Capacitor Values - bit.ly/3SoXtRxWorkbench Wednesdays - Why You Need a Raspberry Pi Pico Development Board by Shabaz: bit.ly/47B4R0sEngage with the element14 presents team on the element14 Community - suggest builds, find project files, and see behind the scenes video: bit.ly/3tmdewvVisit the element14 Community for more great activities and free hardware: bit.ly/3q6YMpuTech Spotlights: bit.ly/3qPrDhMRoadTest and Reviews: bit.ly/3pV5BuxProject14: bit.ly/31wbnJY#0:00 Welcome to element14 presents#0:36 Overview#2:41 Power and Decoupling#3:56 Program and Debugger#5:02 Boot and Reset Buttons#6:17 Turn-On#12:06 Give Your Feedback#raspberrypi #raspberrypiprojects #pcbdesign #pcbdesigning #debugger #debugging #rp2040 #raspberrypipico #microcontroller #microcontrollers

Exploring the Intricacies of Strain Gauges in Mechanical Systems - DC To Daylight element14 presents 2024-01-17 | In this DC to Daylight episode, Derek shows how strain gauges are used to measure strain in a system as it relates to stress. He explains the basics of how strain gauges are constructed, the proper orientation of them during application, as well has how they are applied to a mechanical structure in order to measure a material's deformation (a.k.a strain). In addition, he goes through a few methods of attaching one or more strain gauges to a Wheatstone bridge in order to extract a miniscule voltage from the strain gauges as they work.Discuss the episode and ask Derek questions on the element14 Community! bit.ly/3Hs17DDHow a Wheatstone Bridge works: bit.ly/3ZWYjXJEngage with the element14 presents team on the element14 Community - suggest builds, find project files and behind the scenes video: bit.ly/3tmdewvVisit the element14 Community for more great activities and free hardware: bit.ly/3q6YMpuTech Spotlights: bit.ly/3qPrDhMRoadTest and Reviews: bit.ly/3pV5BuxProject14: bit.ly/31wbnJY#0:00 Welcome to DC To Daylight#0:36 Strain Gauges#7:00 Attaching It#13:33 Measure#15:31 Give Your Feedback#sensor #sensors #wheatstone_bridge #wheatstone

Creating an IMU-based 3D Mouse with an ESP32-S3 element14 presents 2024-01-05 | Why is nobody making a mouse with a motion sensor!? All the mice Clem could find online use optical sensors, so he asks the question: why not use an IMU (inertial measurement unit) as a way to track the movement of a mouse in space?Armed with a PCB he made in KiCad and great ambitions, he soon encounters the truth: it's really hard! The math is challenging, and the outcome would barely be usable, but Clem also learns that building a 3D air mouse this way would be quite easy.Find all project files and ask Clem questions on the element14 Community! bit.ly/3vouqV2Engage with the element14 presents team on the element14 Community - suggest builds, find project files, and see behind the scenes video: bit.ly/3tmdewvVisit the element14 Community for more great activities and free hardware: bit.ly/3q6YMpuTech Spotlights: bit.ly/3qPrDhMRoadTest and Reviews: bit.ly/3pV5BuxProject14: bit.ly/31wbnJY#0:00 Welcome to element14 presents#0:21 Overview#2:04 The PCB#5:09 Assembly#7:18 The ...
