Simple tests using the WeMos D1 R2…

August 25, 2016 | ESP8266 | By: Mark VandeWettering

I didn’t have a ton of time to tinker when I got home, but I did play a tiny bit more with the WeMos D1 R2. I got it mounted on an old breadboard that I had previously used for Arduino experiments, and then tried reflashing it with new, fresh NodeMCU firmware that I built […]

New WeMos D1 R2 boards have arrived…

August 24, 2016 | ESP8266 | By: Mark VandeWettering

I just got a trio of WeMos D1 R2 boards from Banggood this morning. I haven’t had a chance to do anything with them yet, other than power one of them on and check it for basic function, but I thought I’d give a brief review. For those of you who maybe haven’t been tracking […]

A new theory of dorodango…

August 22, 2016 | Dorodango | By: Mark VandeWettering

Okay, I’ve done two, with nearly identical outcomes: a fine network of relatively shallow cracks in the “capsule”, the thin layer of fine particles which encapsulate the core. I’ve been rereading various accounts on how other people make dorodango, and have noticed a couple of differences which I think I am going to test. I […]

Dorodango cracks again…

Sigh. My second attempt has also cracked, although it is beginning to look pretty shiny.

Ordered some ESP8266 boards in an Arduino form factor…

August 20, 2016 | Arduino, Embedded, ESP8266, Hardware | By: Mark VandeWettering

The ESP8266 is an amazing little processor: cheap and capable and (most interestingly) WiFi enabled. I have some of the older “nodemcu” boards that I got for about $7 each, but there are newer alternatives that include up to 4M of flash memory, and a variety of interesting form factors. I noticed that WeMos was […]

FFMPEG overlay needs “repeatlast” argument…

August 17, 2016 | Video | By: Mark VandeWettering

I use ffmpeg to add some information overlays to the videos that I often upload to YouTube. I’ve documented these before, but I had a problem that arose from time to time that I never figured out: occasionally my encodes would seemingly just go on forever, and never terminate. I discovered today that this was […]

No! My precious dorodango!

August 11, 2016 | Dorodango | By: Mark VandeWettering

Eek! I was getting a bit impatient with my dorodango, so I decided to leave it out in the open air when I went to work today so I could let it dry out a bit. I returned to it having dry cracks! Note to anyone attempting this: don’t be impatient. Let it dry out […]

Dorodango: Having (or rather making) a ball with just mud

August 9, 2016 | My Projects | By: Mark VandeWettering

On Sunday, I started a new project which on the face of it, seems like an enormous waste of time, but if you’ve been reading my blog for any period of time, you know that wasting time is pretty much the bread and butter of my online presence, so here we go. I’ve started work […]
