This project enables a user to first download historical financial data from Yahoo Finance. Then, using that data, or any other data source, to test stock trading strategies. The user can choose conditions for buying and selling stocks based on many variables. The code is available for viewing, downloading, and forking on my GitHub here.
This project source can be found on my github here.
This project is a single webpage to calculate time based tokens for two factor authentication, just like Google Authenticator or Authy does on your phone. There is no network connection necessary, so it can be used offline and you can be sure that I am not stealing your codes.
The project can be used live here.

Have you ever wanted to take a YouTube video on the go with you without needing to download the video for offline viewing in the YouTube app? Or perhaps you want to listen to a YouTube video on your mobile device faster than 1x. Both of these are possible if YouTube videos could be added to a podcast.
I have created a web service that allows a user to simply enter a YouTube URL and the video is downloaded, converted to MP3, and then added to a podcast feed that can be subscribed to easily by any podcatcher.
This project is a PHP implementation of my idea for a schedule generator. This means entering in all/any courses that you want to take along with the available sections and the times it meets, then generating every possible non-conflicting schedule.
You can use the schedule generator project here.
You can use the University of Richmond specific version here.
The code is available on my GitHub here.
Pictures from my new Valhalla Scientific 2701C
Tricky to date the device, the latest date code I could find was around 1995, but it included parts from around 1983. Valhalla mustn’t sell many of these since there is such a mix of date codes and low serial number of only 1013. PDF manual.

I’m creating a python based interface for my new HP 3457A using a GPIB to USB interface. I’ll upload updates here.
It has pretty much all the features of the Agilent/Keysight 34461A including large readout, trend plot, histogram, and statistics.
I also included all the HP’s specifications so that it can show the range of possible values from the nominal reading.
If anyone is experienced in Python, then I would really appreciate help with the code.
With python 2.7 installed, double click on the dmm_control script and then make sure that all the dependencies are installed.
You can find the code at github
I bought an IN-18 Russian Nixie Tube clock that can be controlled by RS-232 (Serial), so obviously I got to work writing a program to control it through an arduino uno. The materials that you will need:
The RFID Window Login requires the following items:
This is a simple example program of how one could use RFID to operate a door lock. What you will need:
This RFID reader will read a keycode and print it to a 16×2 lcd and also print it through serial. You will need:
