As my last post conveyed, I had gotten the pesky Ryzen APU to boot and work with Ubuntu 20.04. Everything seemed to work fine. The peppiness of the CPU was loads faster than the A10-9700 APU it replaced. So I thought all was well. ……Not so much! By using ‘ACPI=off‘ in the kernel arguments, I …

Ubuntu-Ryzen-UEFI Madness (Solved!)
I have probably installed some variant of Linux at least 70 times in my lifetime – probably much more. I had just purchased two sets of components for my home-made Render Server Farm. The motherboards were Biostar and the CPUs were A10-9700G AM4 by AMD. The initial installs went without a hitch using Ubuntu Server …

ESP32 UDP Broadcast Tribulations
As part of my Weather Station upgrade, I am having the ESP communicate status over UDP (like a heartbeat I guess). This will inform me of current sketch version and a few other parameters because it is remote and this would function as a rudimentary ‘Serial Monitor’. I’ll tell yah, I spent about 4 days …

Weather Upgrade to ESP32
I tried to use the MKR1000 for my weather board upgrade, but it didn’t seem to be ready for prime-time. The damn thing kept locking up. This was before I located it remotely in my shed, too. I ended up getting a NodeMCU ESP32 (WROOM-32) instead. These are fabulous little boards – they actually have …

EmonCMS Inputs and Feeds
Further info on the wireless weather station and the logging app/site EmonCMS. EmonCMS is fantastic for logging and displaying your sensor data. I have setup a server on a Beagleboard XM, as I mentioned in previous post. It works flawlessly if you treat it right. What I mean is that messing with inputs and feeds …

Wireless Weather Station Update
There are tons of weather station how-to sites on the Web. I am not going to run through the how’s and why’s of setting one up. I will add some info that has helped me get it where I wanted it. First a little background……. I had started this project about a year ago. In …

NodeMCU (ESP8266) upload sketches wirelessly
More on the NodeMCU (V1)….. This little booger is great! I have tried all kinds of wireless upload solutions with Arduino (Olimexino with ESP8266, Nano with various wireless devices) and the end result of actually uploading the sketch never succeeded. It all had to do with the reset aspect which causes the bootloader to accept …

ESP8266 Exception (3)
I swore I had the NodeMCU running on WiFi before, but after uploading new code (not new ESP8266 firmware either) that accesses the wifi library, I got crazy output on serial monitor. Basically it was an exception and a stack dump (I needed Imodium for my NodeMCU!!) that repeated after any call to the wifi …

Converter Now Works with LuxCore
I had some time to go over the changes that new update to LuxRender has unleashed. I am very happy and impressed. I have been avoiding LuxCore API, as previously mentioned, mostly because node implementation was incomplete. The gaps have been closed and materials all seem to work in nodes. There are a few things …

LuxRender Progressing Like Lightning…..
I have been doing all this coding for Blender and LuxRender via my Converter, which takes Blender Internal materials and converts them to LuxRender materials suitable for rendering. The last LuxRender plugin for Blender I installed had an update feature found in the ‘User Preferences’ section, so I went ahead with updating. To my surprise, …
