DataVault Concept: Example Code
I have created two programs which transmit a string over a wire, from one arduino to another. The transmitter converts the string into characters, and then converts those into 8 bits, which is sends to the receiver by using digitalWrite(). An Ascii lookup table is available here. The hardware for this is a simple wire […]
P-140 Electronic Logbook Update 1
This week I mostly finished the advanced search feature for this project. It is now possible to search in a variety of ways. It is possible to search for Records by Post Title, Message Body, or Journal name, as well as by Post date. It is also possible to display all individual posts matching […]
Icarus II (P-142) project reference document
I have just finished a report containing a writeup of all of the equations used in the Icarus project. They have been formatted, checked, and referenced. I think this would be very useful and time-saving for anyone else working in rocketry, either as a hobby, or developing a game, or a simulation. I used latex […]
Thermal Imager: Progress Update 4
I have done some more research on the issue described in my previous post, regarding the Field of view of the thermopile. I have learned that, since thermal sensors operate on a different wavelength to visible light ( I believe the MLX90620 thermopile that I have been using operates between 5 and 16 micrometers) conventional […]
P-139 Nickel-Iron Battery (Edison Battery)
While working on one of my new projects, the DataVault, I realised that many current day battery technologies are sorely lacking. The objective of this project was to design a repository for data that would last for 100 years. Most rechabatteries have a lifespan of 5 years, maybe a little more. I discovered one type […]
P-140 Electronic LogBook
The goal of this project is to replace word processors and text documents for general purpose note taking. I use these documents myself, and they are suboptimal for regular and extensive note-taking. They usually do not have adequet searching or organisation functions for individual “notes”, and treat the entire document as a single block […]
Star Commander Update: 30/3/2014 MS1 Alpha Release
Over the last two weeks, I have brought this game to the point where I can do some live testing over the internet. I can’t do any internet testing myself, since all of my test machines are on the same LAN. Testing the game servers, database servers, etc over the local network can only go […]
Thermal Imager: Progress Update 3
Unfortunately, I have run into a fairly serious issue with this project. The problem is that the thermopile that I am using (MLX 90620) has a wide field of view, 60 degrees. This means that when I pan and tilt the thermopile and take successive scans, each scan area overlaps the previous one, resulting in […]
