Pain relief

Peaceful banner
It cost me half a day and half a night of agony, but I solved a mystery. One CyberKnights customer is a print shop. I had been working in short bursts there because I would swiftly (circa 20 minutes) get tired, so tired I looked like a Reach Toothbrush ad (the “flip-top head” one). On Thursday night, as I walked out through the workshop, the front section being locked, I walked past a section where a drum of solvent had been left open. By the time I got to the back door, I had a screaming headache, dizziness, overwhelming tiredness and was greying out. Mystery solved. Now all I have to do is work there when that solvent is not in use.

new life for an old (FTX) PSU, improved life for one human

the LEDs on this 5m strip happen to emit light centred on a red that does unexpectedly helpful things to (and surprisingly deeply within) a human routinely exposed to it. it has been soldered to a Molex connector, plugged into a TFX power supply from a (retired: the MoBo is cactus) Small Form Factor PC, the assorted PSU connectors (and loose end from the strip) have been taped over. the LED strip cost $10.24 including postage, the rest cost $0, the PSU is running at 12½% of capacity, consumes less power than a laptop plug-pack despite running a fan. trial runs begin today.

boundaries

pushing the actual boundaries of the physical (not extremes, the boundaries themselves) can often remove barriers not otherwise perceived. one can then often resolve an issue itself, rather than merely stonewalling at the physical consequences of the issue.
