Good morning world.
Today I'd like to hear about your solar powered technologies, your sunlight readable screens, your low power - long battery life devices, and your still useful retro tech.
Please to advise?
@ajroach42 This request is 90% of the interesting things in the world.
I’ve been daydreaming about DIY’ing my own tablet for a while now. Less now that PineTab is on the menu, but:
3 colour E-ink screen, quick redraw, about 10 inches.
18650 batteries or such for easy replacement/recharge.
Snap in HackRF blue and 20w HF linear amplifier.
Integrated solar panel in the cover: ~12w.
La, it would be lovely infotech art. I think I could kludge it together.
@onan @ajroach42 Oh, Lordy, so would I... I hope to katamari it together someday. Now and then I search for e-ink screens to foot the bill, and naught quite do yet. They can be cheap, quick, large, 3colour, but not all at once, haha.
I’d go for slow screen, save that for any radio geekery (a secondary mission objective), I’d want decent redraw for fldigi spectrum and such. Anyway, 3-8 colour e-ink is my ultimate ux happy space.
@onan @ajroach42 Ohhh... Oh, a grand idea, thank you. That would need some tweaking for DE display of fldigi and such, but might be much cheaper and quicker. Yes, I like this idea. Especially if they could be on one side, 2-3 of them tucked in quite closely. Fast on the left edge for the waterfall display.
#ShufeiStar e-ink tablet idea.
@Shufei You have a source for 10" 3-color, quick redraw/partial update eink screens?
@ajroach42 Nyet, hence my patience, haha. I’ve dug around here and there, but most of the big screens are pricey 16 greys, which is jake, but... For aesthetic and cultural reasons, I at least would like red too.
1972 Bush TR230 transistor radio (same age as myself) as its LF and MF (AM) only I normally use it to listen to Radio Caroline (former pirate station sometimes broadcast from an former fishing trawler) particularly when I am washing the car (I don't want to pollute the environment by running the engine for the car radio, nor deplete my vehicle battery as its a modern DSG transmission rather than stick and can't be push started!)
I am very cautious about PV-solar anything. I believe that responsible energy consumption (enough to do the job, without extravagance) does enormous good in the world, but on the other hand, one must consider where the source comes from. And PV is an incredibly dirty, energy-intensive technology. It generates toxic waste when it's produced, it ends up as toxic waste when it's broken or no longer usable, & there's some doubt as to whether most cells ever generate net energy.
I suggest you look into the ExternE studies done at the University of Karlsruhe, a remarkable attempt to quantify external costs of energy supply technologies.
Personally I'd rather be around something which is sealed into a sturdy steel container than something which is leaching arsenic into the groundwater.
But I don't intend to continue this discussion here, because challenging beliefs with facts never makes anyone happy. You know where to reach me.
1) A big fan of solar powered wrist watches. No batteries to replace and run for months after a decent charge in sunlight. One big clear chrono and a diver watch with chrono and bezel.
2) Inherited mechanical watch with a tab that opens the back and lets the movement fall out complete. That's what I call Right to Repair
3) 10 year old original Kindle still doing its thing
4) Android 2 tablet that works as a spare kindle with backlight
5) Minidisc still rocking
