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...

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...

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...

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...

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...

Gray counter
Log from YGREC8
20200810: see 122. Updated Gray Counter for the rest of the story !I must make a Gray code counter ! It is not obvious why but it's an important piece of circuitry that is required by the debug/test port... Have a look there for some background :4. The...

[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...

Firmware hacking
Log from Model S BMS hacking
Here is a rough schematic of the isolated bus circuitry. It looks like there is some shared "open collector" style bus on CH4 of the isolator, with D8 and (I assume) a pullup on the BMS controller board. But so far I've only ever measured this line being...

Update log 4 Vacuum tube sound system part 1 - sound processing
Log from Retro-futuristic automobile control panel
My dear readers, today I will fascinate your eyes and minds with this beautiful work of art.Made in a hurry. I will draw the schematics later by hand like usual.The sound system is based on subminiature Soviet Union vacuum tubes and it consists of 5...

Afterthoughts…
Log from A Versatile AVR-based Data Recorder
With the testing of the AVR Data Recorder completed and a few sample test runs, I was fairly satisfied with the performance and features I was able to pack into this little device. The flexibility, hardware support and program-ability of using AttoBASIC...

New fertilizer, pH meter disassembly, LED drivers
Log from GrowInBox
Hi!I have a lot of school work to do this week, but I decided that some thing just need to happen today or as soon as possible. So I bought a new fertilizer.The old one - plant food - TNT Complex from hesi has a NPK of 323 which is ok for the vegetative...
