And by bolted, I really mean hot glued 😉#piwars pic.twitter.com/5nr99M9EQf— David Booth (@Worlds6440) February 26, 2019 An update on our piwars progress:Our design is similar to last year, but we've tweaked almost everything slightly.Longer chassis4 motor controllers3A+ inside chassisCustom hatNew 9dof imuNew code to control motor accel/decelTesting control system ✅#piwars #piwarsblog pic.twitter.com/upJVojii1r— David Booth (@Worlds6440) February 27, 2019 What did we learn today?Good question.Today I learnt that a 128×64 i2c oled screen doesn't like having vcc shoved down the sda line. Keyed connectors ftw in future. But for now, I should just pay more attention.#piwars #piwarsblog pic.twitter.com/nNCPAaszTT— David Booth (@Worlds6440) February 28, 2019
