I rewrited all trakd nodes to Vala from C++11. As a result i dropped many dependencies, so total binaries size smaller 2x. But unfortunately did not fit in 4 MiB TL-WR703N (but 8 MiB i think enough) (OpenWRT + LuCI + trakd).Continue reading.
Unfortunately the first iteration of the hardware was too bad. Motor power is low (need worm gear), threaded studs too curves.Continue reading.
I brings to work SSD1306 display to work, but unfortunately it affects steppers. So i decided to remove it for now :(.Continue reading.
At project start i wanted to use TL-WR703N GPIO’s for direct control. But when i pulled out almost all gpio from openwrt table, i found that only few of that really accessible. So i decide to add simple USB bridge based on sparkfun arduino pro micro (china clone costs less than atmega32u4 on local market).Continue reading.
