New GUI and Python Library!
Log from Memtype: Open Source Password Keeper
Having a CLI tool is fine, everyone can manage the credentials on the device and layouts, but having to find what flags to use or how the files have to be constructed can be a problem to some people.An important feature of MemType is that it has to be...

Simple Python Interpreter and Plan
Log from Kyazuken: a Java-like language
The interpreter can run simple programs but is basically a limited C interpreter for nowvoid main(String[] args) { println("Hello World!"); if (1 + 1 == 2) { println("1 + 1 = 2!"); } exit(0); } This executes. It's not super hard to get running...

Reading serial data with Python
Log from Load Frame Update
At this point in the project I've given some brief descriptions of how the Arduino is reading the digital signals from the quadrature encoder that measures position and the analog output of the load cell. These data are then written to the serial port...

pyANS update – Python ANSIart scroller
Log from pyANS a RaspBerry Pi ANSI Art Scroller
I’ve had another look at pyANS this morning after getting it up and running in a centOS VM. In doing so I have learnt a few things.The script itself is only good for Python 2.7+ so I have now added a check for that prior to running.The escape code [2J...

Defocused Computer Perception - Python & OpenCV
Log from Happy Vertical People Transporter
My previous attempts at computer vision was all done in Python with numpy. With arrays I detected movement (very poorly) and distance with a laser and some trigonometry. This time I wanted to try and figure out openCV. Turned out to be so easy! The basic...

Custard Pi, Python and Servos
Log from Web powered antique wind gauge
The cable, and the Custard Pi turned up.First, I'm trying the servo on an external power supply. I'll try it from the Pi later, but as I already know it works from an external supply, I want to change the minimum possible.With the servo signal pin connected...

RasPi Button debounce in python
Log from Potpourri
I needed to debounce a RasPi button in python, and found that the software in this link has problems: sometimes the button press is ignored. Here's an improved version fixing the problem. It uses the GPIO hardware to initially detect the button...

boost::python and Connected Components
Log from PiMoCap
Boost Python update This looks interesting, I'll have to take a deeper look at it S.P.E.A.D.. A fast protocol for throwing NumPY Arrays about. Berkeley, so you know they're serious. Could be an interesting reference for what I'm doing. And certainly,...

Efficient Sonar Gridmaps in Python
Log from PyRover
One foundational challenge for a lot of hobby robotics is navigation and localisation. We can access cheap sensors in the form of IR and sonar, which give distances to solid objects. We can use IMU's and wheel encoders to estimate distance and direction...

Raspberry Pi Python Possum Pictures
Log from OpenTrap Smart Animal Trap
While the initial intent of this project was, and still is, helping to control the population of feral and stray cats, the possums under my deck have proven helpful in testing the system. I've been hoping to trap the Mom and Baby possum together so I...

Final Python Code...we're finished.
Log from Single-cell Li-Ion Powered UPS for Raspberry Pi
This is (hopefully) the last log. The project is complete at this point. There are some bits of code that is necessary to get the UPS working properly. Paul Versteeg upgraded the code to include a logging capability and also provided a service file for...

Coding the Software side (Python)
Log from Present! Availability sensing for Zoom meetings
Now that the micro controller is programmed, Remainder is to code for reading the serial input and turn the camera and mic on/off depending on the situation. Needed to find some way that Zoom application can be manipulated thru code. As an API for zoom...

Writing an Assembler in Python
Log from muCPU: an 8-bit MCU
As I was writing some simple test code to run on my processor testbench (in iSim), I found that it was tedious and slow to write hex instructions from assembly mnemonics. What better solution to a problem that is tedious than a program that does the...
