Just found & joined Lemmy and so want to add to it by starting a community on a favourite (time & money consuming!) hobby: modular synthesis.
This is my current system although I'm currently building a Befaco Hexmix, Robaux LL8 and a Sonic Potions Penrose quantizer.
I have a new case arriving next month that's portable so once we can go outside and congregate again, I'm going to look at playing some shows (if I actually have any music and haven't just disappeared down a noise rabbit hole!)
2 years on and the system looks like this:

Another case by Case From Lake and plenty of modules that I managed to acquire through luck such as the ACL Sinfonion for £750!
I'll have to go through my ModularGrid page to update my racks there and post them
Not just bumps but designing infrastructure so it forces the drivers to negotiate it at lower speeds.
Simple stuff like narrowing the approach to junctions and roundabouts so it has to be taken at a slower speed than it being a wider aperture when minimal braking is required.
Raising the pedestrian or bike where it crosses a road (on side streets) so the vehicle has to slow rather than the active transport methods.
Reallocating road space to wider pavements and segregated bike lanes so streets are mixed modal.
