I had the good fortune of running into someone who read IC Friday, at random, and that reminded me that I have been quite delinquent in updating ublog. My work load has tripled over the past few months, so I have been busy, however, I will make every effort to keep this current. Below are my non-work-related engineering projects that are in various state of completion, hopefully I will create writeups for them and you will find them interesting.
- DJ Box — Mini-itx fanless system with wifi to encode and stream, on the fly, audio from my turntables. Welding a custom case (see below) and adding one or two analog VU meters.
- MIG Welding — Might not really be considered engineering, but at least it’s arc welding. My family got me a 140A MIG welder for my birthday in February and I purchased everything needed for steel and aluminum welding, so I will try to make something interesting. Maybe use it to destroy some solid-state relays (on video).
- Functional IC Decapping — IC Friday will not be continued in its former state where chips were bathed in acid and imaged. I think it will be better for everyone, especially myself, if I create fewer but higher-content posts. I am thinking of either decapping some analog circuits without destroying the majority of the package and demonstrating some optical glitching, for example. Another idea is to image the chips but write a clear post on the identification of various sub-circuits on the IC substrate.
- Sleep-State Staging EEG Amplifier — I am have been looking at the most simple method to create an EEG amplifier and LabView combination that is capable of discriminating sleep states. I am then planning to post some data from myself.
Feel free to post a comment if there is something specific that you want to see written up, hopefully I can get to it in a reasonable manner. It’s good to be back!
