k/GT MTB link trail completed

 The Kinmathatakinta/George Town mountain bike link trail is now completed. In addition to the York Cove to Agnes St rivulet path, a trail has been forged through the trees in the Alfred St. right-of-way (which , although a declared road, had been overgrown for decades). A set of large pipes make a crossing across the small creek that used to cut across the "roadway". You can now ride from the centre of town, at the rusty pelican for example, to the trail head without going on the main road in/out of GT. 

The rusty pelican

Sign posts mark the way

Big "aggie pipe" for a creek crossing

Not the right bike for actually riding the trails,tho

The Mt.George trail head

 

Flags unfurled

ESP32-2432S024R "nixie" clock with micropython

Working on a (simulated) nixie tube clock on a "Cheap Yellow Display" in micropython. I used the nixie images from macsbug's M5Stack clock ( https://macsbug.wordpress.com/2019/06/16/m5stack-nixie-tube-clock/ ). Converted with the img2rgb565.py utility from rdagger's ILI9341 library  (https://github.com/rdagger/micropython-ili9341). The library had a RST pin input that the CYD did not need, so I just commented that out, is this the "right" way to fix it ? who knows ? it works. Update: added a "beats" internet time and date display in little round "nixie" tubes... 

The board has lots of built in stuff - SD card, battery charge circuit, 2W audio amp, an LDR and a RGB led
