Technical Musings From a Learned Idiot

And perhaps some interesting projects for you.

Asynchronous Event Driven PowerShell Serial Communication

Just in the past few months, I’ve learned that, like other scripting languages, PowerShell supports using Classes, which opened up a new world for me on what is possible. Did you know that PowerShell can also communicate via the Serial (COM) port? Of course, you knew that, because you’re here trying to understand why asynchronous…

Parametric Dipole Antenna Generator for OpenSCAD

Parametric Dipole Antenna Generator

This is a parametric dipole antenna mount generator. Enter center frequency, print, cut wire to element length.

Notes on finding the Apex Angle of an Axicon

For the handheld laser wire stripper project, I needed to find the Apex Angle of the axicon so I could place an order. As it turns out, different suppliers specify the Apex Angle differently, so it can be a bit confusing on how to order axicons. For Thorlabs, if S1 is the apex side, let…

Handheld Laser Wire Stripper

New Invention: Truly Handheld Laser Wire Stripper

Handheld Laser Wire Stripper While I am no longer a Laser Application Scientist at Control Laser Corporation, I still think about how to solve real problems with lasers and other technologies. I have created a new invention and am looking for funding to bringing it to market: a truly handheld laser wire stripper that solves…

Sergey Baklykov – Real Russia

Sergey Baklykov from Real Russia, sends a message! I have a great appreciation for the Russian culture and the history of Russia. My thirst to learn more and to understand this better brought me to YouTube and ultimately to a channel called Real Russia where a man, Sergey Baklykov, travels around Russia with his friend…

Miniaturized Phased Array RADAR For UAVs/Drones Project Progress

I started a project a while ago on how to create a miniaturized version of a phased array RADAR that could be used on very small UAVs/Drones. Extensive research was performed on this subject, which took a couple of years to complete. Was I to use low frequencies? Do I need an upcoverter? If so,…

ADS-B Receiver and Server based on Raspberry Pi and RTL2832L chipset USB Dongle

ADS-B Receiver and Server are Operational

A while ago I purchased a few of the RTL-SDR USB dongles for the purpose of exploring Software Defined Radio (SDR) and to also act as a poor-man’s spectrum analyzer. While cleaning some things up yesterday, I found these receivers and decided to see what I could use them for. I was surprised to learn about tracking and plotting aircraft via the ADS-B radio signals that many aircraft transmit.

Analog Devices Chip Full Decapsulation

Presenting at the 42nd International Symposium for Testing and Failure Analysis (ISTFA 2016)

One of my main areas of study as a laser application scientist with Control Laser Corporation is in perfecting the process of laser decapsulation of semiconductors. As my entire life has revolved around semiconductors, and the electronics industry in general, this work is right up my alley, as we say. I work with some of…

Lance Fordham at Dipaul in Russia

Featured in the Russian Technology Magazine «Эксперт+» (Expert+)

I learned the other day that I was featured in the Russian technology Magazine «Эксперт+» (Expert+). I have to say that I’m a bit proud of this, as I appreciate the country and culture of Russia very much. I’ve done quite a bit of business there over the past couple of years and have made…

Dynamic Phased-Array RADAR for Drones, AD9959

It’s been a long time since posting anything here so I figured I’d give an update on what’s happening in the lab. Also, the fine folks from Analog Devices had me at their facilities up in Massachusetts, which was pretty awesome. Such smart people they have working there, and so many expensive analysis machines! While…
