wondering about the correlation between power pulled from river and sun here (river power goes down when sun power pulls...).

maybe this is because of the charging schematic - both charging outputs (solar-powered charger and river-powered charger are connected to the battery in parallel...). worth checking river voltage, since that's more directly correlated to flow speed.

26 03 19_dataflow continuation proposal

As a first reflection/research trajectory (10 days):

Looking critically at what Dataflow actually is/has been/was envisioned as, especially through lenses of other critical computing ideas (permacomputing, Holistic Computing Arts, crtical infrastructure, see below) and producing a written/illustrated document that reflects on this and communicates it clearly. Also gladly inviting the other minds and voices involved in this project so far to add a reflection (maybe after there is already a clearer start/proposal). I think this is a way of getting to a shared idea of where we actually are now, and then openly pondering and imagining what it could be in a way that is informed by the shared understanding.

i.e. one important part for me is questioning this as just a \"low power / maas-powered website\", because this part is really just one node in the large network of hops before the dataflow website reaches your device (i.e. think through the hops of your device to a wlan router to a cell tower to a data centre which tunnels the connection, and then its route to this \"low power\" webserver - through 4G cell towers to this little dataflow with a battery and charging... In fact less energy would be used by just uploading a lightweight static website to one of these datacentres (ideally one that's powered by renewables) and cutting out half of the cell tower hops and cutting out the dataflow battery charging/discharging...

So this also as a motivation for finding other ways of sensing and sharing (i.e. situated sounding instruments)

First outcomes:

- a document (above) reflecting on dataflow
- a lightweight maaslab website aggregating the various digital communications (maaswacht info, dataflow info, ...)

Looser thoughts and imaginaries
- Dataflow touching Maaslab's digital presence - critical digital infrastructure
- experimenting with situated, water-connected systems for (different ways of sharing, engaging with, being together...)

Music for Waterways explores

... site-responsive instruments built for the experience of being with, listening to and soundmaking in rivers 

… river-based music* making

My first attempts to collaborate with the rivers Mur and Maas resulted in sinking rafts built on upside-down buckets which play quiet aleatoric music as they push wind through organ pipes. Since the pipes have a nuanced acoustic response to changes in air pressure and flow, and transition between open-ended pipes (above water) to detuned close pipes (within water), they sonify their physical relation to the water and raft. Adjusting their arrangement on the raft is a sort of physical programming. But it's really in the situatedness with and in the river that the music emerges. From the moment the raft is released, the river takes over, pulling and sinking, and the music just happens, piping as the raft bobs with the current and ripples on the surface, composing the music and uncomposing themselves. These moments of letting go and listening created a sense of togetherness with the river.

During my residency at the Maaswachter’s studio, next to a sometimes quite turbulent section of the Maas, my music making attempts were more shore-based. Lighter weight water flutes carved from found reeds and bamboo. I realised though the experience and the music is better shared, a favorite moment \"river song\" made one afternoon with david martens, the geese sang along.

Following this experience, I'm exploring ways of further developing this practice in more participatory formats, i.e. in an afternoon raft building workshop, sharing simple tested techniques, inviting participants to co-create a raft from bamboo, buckets and bicycle tubes and then transform it into a water organ. Large enough to balance on/swim to/drift along with, framing acoustic concerts in various constellations …
