Atomic Pi – Sometime later …

So I guess it’s been about three months since I last posted anything about the Atomic Pi.  Since that time in April I’ve been using the little SBC as a YouTube machine, pretty much dedicated to the purpose of maintaining my daily fix of YT content.  Ninety five percent of that YT viewing time has been done with FreeBSD running on the little SBC.  I’ve tried a few other options, but FreeBSD works best for me.

Over the past three months, my YT viewing level has probably been quite a bit higher due to the virus.  On some days …

FreeBSD on an Atomic Pi

Figure 1: An Atomic Pi outfitted with FreeBSD. 

I have an arsenal of Odroid XU4 boards that have served me well. But, with the XU4 – I find myself using Linux all of the time.  There is not much in the way of distributions outside of Linux for that nice little SBC computer.  Sure – there’s Android, but that’s not in my plans.

I occasionally like to use Haiku OS, maybe dabble a bit with VisOpSys, and in the past have preferred to use the likes of FreeBSD and NetBSD.  The problem is that all of those operating systems are targeted first towards …

Update for Photon Fun

Figure 1: The Diminutive MCU on a 3 inch breadboard, color inverted

In my last blog post on this topic from over a year ago, I walked through the setup of a development environment for the Photon MCU board (a board made by Particle, a company which is not associated with this author or site in any way. I really like their MCU boards though!). Recently, I decided that the AMD-64, with its tether (in the form of a 110V power plug), its twenty pounds, and its voracious appetite for power, was a poor development machine for a 4 gram MCU board. OK – that was a (slight) under-exaggeration.

RISC for Dogs

Figure 1: I hope my dog likes Risc OS as much as I do!

Some time ago I tried RISCOS to see if it could be useful for me.  I liked it, and in fact it was the only operating system I used on my Pi for the first few weeks after I purchased my initial Raspberry Pi.  Subsequently, I got involved with other operating systems on the Pi, and RISC was put on the back burner.  Recently, I decided to see how much had improved in the time that had elapsed (about a year).

Using a Pi SBC with Shortwave Radio

BUTTERWORTHON-16DIP-SOC-5New Orleans Coast Guard weather fax operates at 4.317  4.344 MHz, so it is far outside of the default (7 MHz CF) filter bandpass of the BPF that I have in the little sidecar SDR.

Currently, there is no bandpass filter switching arrangement within the sidecar, so I have to swap the different 14 pin dip sockets in and out as I change bands (each DIP is loaded with the correct combination of components for the frequencies I wish to use).  It’s  a little inconvenient to do it that way …

New Face for Orange Box Server

pi-orangebox3Figure 1: The Pi (2) powered Orange Box server with its new Face (click to enlarge).

So, the orange box server has gotten a nice facial.  No longer a plain little orange server box, it’s less plain and sports an 800×480 “monitor” screen to keep tabs on what it’s doing.  Currently the monitor is USB powered, but when I can figure out which header connectors on the back of the new face are safe to use for DC power connections, I’ll remove the ugly USB cable looped around on its top.  I have a “cover” on order, and that should hide the edges of the screen and protect it from abuse. The origin of the cover is interesting …
