Stoev · AE1S Science and Engineering Blog_ Gamma Dog Maxi was built with basically the same 3D Printed housing that Charles designed, but extended to fit a large 63x63mm NaI(Tl) detector. It is much closer in size to my main Gamma Dog line with 4" diameter housing and since I was reusing the old Gen3 electronics, this unit received the electronics package with serial number "AS001" Beyond the larger housing size and construction is… ## [Gamma Dog Update: "Gamma Dog Mini" and firmware update v5.9](https://blog.kotarak.net/2026/05/gamma-dog-update-gamma-dog-mini-and.html) _2026-05-06 · Andrey E. Stoev · AE1S Science and Engineering Blog_ Finally found some time to work again on the Gamma Dog project. I had 3 GD electronics modules from the Gen 3 run and a bunch of 38B57 detectors laying around so I decided to turn them into actual units and add some improvements to the firmware. New Firmware release - Current version is 5.9. These are just some of the improvements: - completely new sound library with harmonic suppression and… ## [Demise of the Robot Authors](https://unmakeme.com/2026/03/02/demise-of-the-robot-authors/) _2026-03-02 · unmakeme · Patenting the odd, the impossible, and the unnerving_ Just logging back on to mark the end of a particular legal arc. Over the course of this blog I tracked how Copyright law was addressing the rapidly changing capabilities of generative AI models. You can see those posts at The Robot Authors and Return of the Robot Authors. To summarize, the Copyright Office decided … Continue reading Demise of the Robot Authors ## [Gamma Dog - Rate-to-Tone conversion and Audio Frequency Modifier](https://blog.kotarak.net/2024/09/gamma-dog-rate-to-tone-conversion-and.html) _2024-09-23 · Andrey E. Stoev · AE1S Science and Engineering Blog_ One of Gamma Dog's unique features is the continuously variable tone representing the detected count rate by changing its frequency. The approach is fairly straight forward - the detected count rate in CPS (Counts-per-second) coming out of the detector and into the MCU is converted into an audio tone with the same frequency - i.e. 200 CPS will produce 200Hz tone and 1000 CPS will produce 1 kHz… ## [Efficient Common-Mode Current Choke for EFRW and other portable antennas (1:1 Guanella)](https://blog.kotarak.net/2024/09/efficient-common-mode-current-choke-for.html) _2024-09-04 · Andrey E. Stoev · AE1S Science and Engineering Blog_ I was putting together SOTA/POTA portable antenna kit for my son, utilizing EFHW and EFRW antennas and I needed a Common-Mode Current Choke - something not very large and efficient that he can eventually use from QRP to 100W on 40m to 6m. This is just a quick, easy, 15 min. build, and the result is an excellent and pretty efficient CMC Choke (see the measurements below) for only $25, that one can…
