You can refactor hardware, right?
Log from MC68000 Computer
I'm in the middle of a few free days right now, and I figured it's time to take a look at this project. Things aren't good. Let's go over what's wrong with it:It's not doneIt's not even close to being doneThe 'not being done' is mostly a result of using...

aquaPionics
Details from aquaPionics
This project began with a request from the Incredible AquaGarden, who were busy building an aquaponics system as part of their project located next to the high school in Todmorden, UK. After researching the subject I advised that the available...

Build Your Own Wave Player with CD Audio Quality
Details from Build Your Own Wave Player with CD Audio Quality
PROJECT VIDEOHARDWAREHow to combine two 8-bit PWM output into one 16-bit DAC?Single PWM output can use one output pin to generate analog signals with 8-bit resolution (as we learned in LAB2). However, we can simply create another analog signal via another...

Final bits
Log from Reflecting the sun into your home
Ok we need some way to detect how many rotations the shaft makes, a CPU board, and a Real Time Clock (RTC). We should have some Flash memory as well to store our data points.Photo-Interruptor CircuitAn easy way of detecting shaft rotation is by using...

Controlling a brushless motor (BLDC): Software
Log from FlexSEA: Wearable robotics toolkit
As a starting point, I highly recommend reading AN857 Brushless DC Motor Control Made Easy & AN885 Brushless DC (BLDC) Motor Fundamentals from Microchip. The So, Which PWM Technique is Best? series from TI will then complement your knowledge of BLDC...

Preperation is the Mother of a big Harvest
Log from Aeroponic All-year Greenhouse on a Budged
For the third itteration of my Greenhouse i did a lot of research in aquaponics and automatic growing, because i was bored of watering the plants by hand. My first two designs allways had problems with water leaking out of the water tank. When i used...

Peak Performance Revisited
Log from SpiroBoard Aeroponics pH / EC / Motor Controller
I recently revisited the peak detect issues after a long break working on other projects. I was still dissatisfied with the accuracy of the peak detect circuit. I spent an evening playing around with LTSpice trying various tweaks...

Quick update #2 - Analog-digital conversion module
Log from Bio Balance Detector
Hi guys, There are some progress on many fronts. I met with a potential partner company that could connect me with a University research group to dive a little bit deeper into the bio-electromagnetic phenomena we would like to process and show with our...

Glowing Air-Bubble 3D display
Details from Glowing Air-Bubble 3D display
Origin of this project This is the origin of this project, the illustration of my idea sheet, drew in 1994. At that time, I didn't have the skills or the time to realize these ideas. From around 2015, I started making things using electronic work and...

Audio Architecture
Log from weeBell - personal central office for POTS phones
The most interesting part, for me, of the Bluetooth Handsfree firmware for weeBell has been the audio subsystem. I've never really done real time audio before (aside from generating tones or using a library with a I2S DAC) so it was a good learning...

2:5 Scale KENBAK-1 Personal Computer Reproduction
Details from 2:5 Scale KENBAK-1 Personal Computer Reproduction
Background If you have been following Hackaday for a while, you will have seen on numerous occasions the KENBAK-1, regarded by many as the first commercial personal computer. Ten years ago Mark Wilson introduced KENBAK-uino, a reproduction...

[E1][T][M] Tetent with 1440px screen?
Log from Tetent [gd0090]
1440x1440px resolution at 125% scalingWhat the screen would look like on Tetent (but sharper). This already makes me think back to my Windows Vista on PSP days, but I'm mainly imagining the future present of quietly chilling in bed while trimming down...

GPXR General Purpose ( VR / AR / MR ) XR
Details from GPXR General Purpose ( VR / AR / MR ) XR
In the Maker community there are projects to make Virtual Reality headsets to use with the PC, but these are for wired use, so there is room for a wireless solution that does not involve using a cell phone. Currently the best: https://hackaday.io/project/187343-easy-pancake-lensesAnd...

What shall we wrap it all up in?
Log from Commercial home automation
Any enclosure needs to be easy to access yet provide enough space to get all of our cables in and out without being too big. A tough challenge!---------- more ----------Once our technology solution is chosen, we have to mount it, cable it, make it all...

Using a Counter for the ISR
Log from Simple Concurrent Tones for the Arduino
Using a counter for the ISRI received a suggestion to use a counter and trip method for the Interrupt Service Routine (ISR). While is was not keen as the method (Direct Digital Synthesis) is pretty standard and gives the best long term accuracy. But...
