P-115 Signal Recorder and Data Analyser: Fast Fourier Transform Implementation
I have made significant progress on this project. I believe I have correctly implemented an FFT algorithm in my program. I have tested the out put using THIS sites data, and it seems to match the expected pattern, even though the exact values are not the same. The graphs being produced also look correct. This […]
Weekly Update 8/12/2013: Signal Recorder and Data Analyser
This week I concentrated exclusively on the Signal Recorder and Data Analyser program. It is mostly done, in concept at least, but the Fast Fourier Transform algorithm I am using is proving to be difficult to implement and test. I spent some time on the data visualisation and graphing, which turned out to be […]
Project 133: Wireless Power Concept (Resonant Inductive Coupling)
I have been working on an idea recently to create a concept test of a Wireless Power system. This is basically what is sounds like, “beaming” power from a transmitter to a receiver with no wiring, no plug, etc etc. There are several commercial products using, or intending to use, this system, and it’s unlikely […]
Weekly Update 1/12/2013: Artillery!, Radio Receiver, Signal Recorder
This week I added some new art assets to Artillery, just a fgew player controlled avatars. I am going to have either of them in the full game. I spent most of my time working on my signal receiver and analyser. In addition to building my radio receiver and examining the signal on an oscilloscope, […]
Project 115: Signal Recorder and Data Analyser
Following on from my VLF antenna, I have decided to build a concept test of a Signal Recorder, Digitiser, and Data analyser. What this system will do is pick up a signal on a frequency or a series of frequencies, digitise that signal, store it, and provide the ability to display the signal to the […]
Weekly Update 24/11/2013: Artillery!, Operational Amplifier, Arduino Radio Receiver
I have decided to start doing weekly updates of all my current projects, instead of waiting until I have finished or made a major breakthrough to make a post. This week I spent some time debugging Artillery! and I created an inventory system for it and created some new art assets and new projectile types, […]
Project 114: VLF Antenna Phase 1 Final Report
I have finally finished phase one of my VLF Antenna Project. I am generally happy with the results, the antenna worked, and I did get some definite radio atmospheric activity from the audio amplifier. However, my attempts to digitise this data have not been very successful. I attempted to use an Operational Amplifier (OpAmp) to […]
Project 132: Autostereoscopic Holographic display
I have always wanted to create a “holodeck” or a completely immersive virtual reality environment. This is not yet possible with current technology, but various advancements have come close. The limiting factor in most cases in cost, however, I have discovered a simple method of creating a vert low cost 3D hologram. Firstly, I need […]
