Sunday – the day of gold!
Pee semiconductor! I’m still thinking on the relation of computation (and not just materially) to the cycles of Tiny Mining and the descent into the physical mine – the maps of that descent in silver, in gold
Checking the silver nitrate tests – with breath showing a long worm descent and one smaller worm. Control is not so interesting. Control container was very clear, breath as yesterday showing a few small crystals in otherwise clear solution and urine is silver/grey.
Bright, golden sunlight in the studio casting small rainbow in the heavy metal HM1 sensor protocol.
Preparing for the last potentiostat/voltammetric test with this morning’s sample (today it is un-refrigerated). So we first measure pH – 6.2 of undiluted urine. We start we new electrode, new conditioning solution and conditioning steps. Still no lead:
And while cleaning up, as if to signal the conclusion of mining activities – while clearing up I dropped the pH probe on the floor. It shattered without a sound.
Again more aware of the evening light, bare trees against the sky.
