Generating Sine Waves
Log from An Old Fashion Acoustic Modem for the iPhone
Generating Sine WavesWho thought this would be hard?I have spent a week trying to work this out. Here is the pseudo code so far:Calculate the Mark and Space ratios:A= int(Fsample/Fmark+0.5)B= int(Fsample/Fpace+0.5)Find the lowest common multiple N of...

Porting to the Arduino
Log from Software Phase Locked Loop
FSK ModemThe purpose of this project was to see if I could improve the performance of my Bell 103A2 modem. Initially to see if I could extract the baud clock to mitigate output jitter. Well I have not looked at that (have to investigate other start bit...

Plan for large-scale training run with object detector using Histogram of Oriented Gradients (HOG) and Linear Support Vector Machines (SVM)
Log from Elephant AI
In this large-scale training run I'll be using 5177 negative images, and 750 positive elephant-images. I'll attempt hard-negative mining on 500 images. Hard-negative mining is outlined in the following paper 'Object Detection with Discriminatively Trained...

To pull or not to pull - that is the question
Log from IuT voltmeter for a breadboard
... which turned to have the following short answer - to pull down with a 680 kOhm resistor. For a detailed answer---------- more ----------we need to acknowledge that a floating input of the ADS1x15 results in a rather high voltage reading. Therefore...

Let's do it Right
Log from Ye Olde Nowt
After a bit of research and experimenting, I can now conclude that my initial PCB design has a number of flaws, namely: I choose the only pin that can't be used as button when SPI is enabled, BCM7, for the UP button.I choose the pin that LiPO Zero module...

New power supplies
Log from Hot Hot (Yushengtech) SMT50 OpenPnP conversion
This 48V-12V DC-DC converter handles 10A, pretty sweet, only $17. This will give me a massive regulated 12V supply off the machine's existing massive 48V switcher, which will power the Smoothieboard and any outboard stuff such as the vacuum handling....

Arduino Sketch
Log from Mixed Reality Room Scale Shooting Gallery
Modified from James Bruton's sketch example. This sketch uses the serial connection to listen for servo addresses 100 through 115, then activate, pause, and return each servo called.The Unreal Engine app only has to send the address followed by a newline.This...

Choosing the gates
Log from YGREC8
In case you haven't heard the news yet, there is an open source PDK in the making for a 130nm node, and a promise of free, gratis chips ! https://hackaday.com/2020/06/25/creating-a-custom-asic-with-the-first-open-source-pdk/ This is what I had been preparing...

The ISR
Log from Simple Concurrent Tones for the Arduino
The Interrupt Service Routine This is the most important bit. Its code I originally wrote for a modem project. The ISR is triggered 31372.5 times a second which is about as fast as the Arduino can sensibly go. At this speed you only have 31 us to do...

Log from Everything PCB with OSH Park Hack Chat
Nick Sayer says: I wish I had a really good use-case for flex. All I can think of is just making FFCs, but you can just buy those from DigiKey. :/ Dan Sheadel says: One of the issues with flex is that there's fewer fabs to do it in the US,...
