I’ve just added blu-tack to my range of adhesive components sticking Phoebe together.
I spotted yesterday Phoebe was showing a 3° nose down tilt when on her horizontal test platform. That’s a big problem (3°tilt = 0.05g or 0.5ms-2 horizontal acceleration) and it took me a while to find the obvious source – the MPU6050 breakout had shifted in its attachment to the breakboard – probably loosened finally by too many crashes; it has been surprisingly rugged for a very long time.
Hence the blue-tack to keep the MPU6050 breakout firmly attached to the breadboard – although I’m actually using a different black variety which is softer and stickier when massaged. This means it works itself into nooks and crannies, and then is strong enough to take paint off a wall (it was for sticking my DIY hi-fi speakers to custom stands; it squidged out very thin when putting the two together, and the two were virtually inseparable thereafter). It also matches Phoebe’s colo(u)r scheme better 🙂
I wonder how much this has been affecting my drift control testing recently? Weather is good this weekend, so we shall see.
P.S. That’s not my complete set of sticky stuff I use; the last is double-sided padded sticky tape which sticks the Raspberry Pi and breadboard to the frame’s top plate which provided a very strong bond while the padding does provide some noise suppression. I left it out from the blog’s title as it was too long!
