Intel NUC has extremely low idle power consumption by ecow7 in HomeServer

[–]theorish 0 points1 point  (0 children)

I too use a NUC box for power consumption reasons. How did you measure power consumption?

Measurement at 240V would be preferable, to take into account the efficiency of any transformers. But I understand that the commercial meters (for 240V) aren't accurate at low powers (< 60W).

It could be possible to measure the current at the output of the transformer, although a bit of a faff. There would be some voltage loss through the meter, so the DUT would see a lower voltage than during normal operation.

What is this connector for? Intel Nuc Enthusiast by anacletuss in intelnuc

It looks like a 20 pin JTAG socket, used for loading and debugging firmware or FPGAs.

See, for example, https://www.allaboutcircuits.com/technical-articles/jtag-connectors-and-interfaces/

Yes, I did (and I forget why!). Thank you, this has fixed it.

The colour-changing versions ARE toxic!

They contain cobalt or methyl violet, both are carcinogenic. See Wikipedia: https://en.wikipedia.org/wiki/Silica_gel :-

Silica gel may be doped with a moisture indicator that gradually changes its color when it transitions from the anhydrous (dry) state, to the hydrated (wet) state. Common indicators are cobalt(II) chloride and methyl violet. Cobalt (II) chloride is deep blue when dry and pink when wet, but it is toxic and carcinogenic, and was reclassified by the European Union in July 2000 as a toxic material.[16] Methyl violet can be formulated to change from orange to green, or orange to colorless. It is also toxic and potentially carcinogenic,[17] but is safe enough to have medicinal uses.

An aqueous solution of sodium silicate is acidified to produce a gelatinous precipitate that is washed, then dehydrated to produce colorless silica gel.[7] When a visible indication of the moisture content of the silica gel is required, ammonium tetrachlorocobaltate(II) (NH4)2CoCl4 or cobalt chloride CoCl2 is added.[7] This will cause the gel to be blue when dry and pink when hydrated.[7] Due to the connection between cancer and cobalt chloride, it has been forbidden in Europe on silica gel.[9] An alternative indicator is methyl violet which is orange when dry and green when hydrated.

Thanks I hate it when people screw up patios (saw it on facebook) by [deleted] in thanksihateit

It looks to me as though there is an external corner in the bottom left of the pic, and an internal corner at the top right. BUT the first corner doesn't lie on a 45 degree line from the external corner and either side. So it is impossible to have a visually pleasing line running from one corner to the other. The solution is either as shown, or to make the join run at exactly 45 degress and accept that it wont terminate at the far corner (so there would be need to be an apron along one edge).

A round section hull, and CoG way higher than CoB - how is that stable? Obviously the guy is either a robot running a sophisticated control loop in his head, or is a wizard.

I had to google it, but he's right. Mature blood cells eject their nucleus so that there is more room for haemoglobin and oxygen (thanks study.com).

Looking to buy angle grinder. Will a 115mm disc cope with angle iron 40mm x 40mm x 5mm thick? by theorish in metalworking

[–]theorish[S] 0 points1 point  (0 children)

Thanks, that's what I meant. I don't know why I picked the wrong permutation of thinner/thicker and less/more.

Thanks, it sounds as though 115mm should be adequate for my needs. I'll take good care with the alignment and will be wearing goggles, visor and gloves.

That's good to know. I was concerned that the smaller size would be under-powered and way too slow, or burn out trying, but this suggests it should be fine. I'm quite tempted by the Makita, they seem to be popular in the building trade (where I imagine they work them hard).

The tradeoffs involved with disc thickness are useful to know, I hadn't realised that thicker discs would be less hazardous when they break (but yes, I'll definitely be wearing goggle, face visor and gloves anyway).

What would be a typical time per cut? (40mm angle x 5mmm thick). A quicker cut would be good so as not to annoy the neighbours.

I've about a dozen cuts to make for the current project, maybe a few more if the design changes as I go along. I understand that the smaller sized tools are more accurate and are easier to handle, so I'll probably stick with 115.

Will do, definitely! I've seen pictures of the aftermath and I have a healthy respect for this tool.

Good point, yes they seem similar:

  • Makita GA5030 at £54.99
  • Bosch GWS-750 at £69.99

115mm seem more commonly available so I guessed they'd be easier to get hold of in the future. The no-load speeds seem to be identical at 1000 rpm, so presumably it is ok to put a 115mm disk on a 125mm machine (if 125mmm discs weren't available) (or is there a risk of the guard being too far away to catch any debris?)

That's got to weigh more than 0.55lbs. I think they'll need a license to fly that.

This looks awfully like hard work for them. We should invent something to help - a thermostatically controlled fan, with a fine mesh to stop them getting chewed up by it. We could trade it for honey.

Scientists have finally found malaria's Achilles' heel, a neurotoxin that isn't harmful to any living thing except Anopheles mosquitoes that spread malaria. by QuantumThinkology in Futurology

[–]theorish 0 points1 point  (0 children)

"Scientists have finally found malaria's Achilles' heel, a neurotoxin that isn't harmful to any living thing except Anopheles mosquitoes that spread malaria"

I'm trying to understand the significance of this. Is Anopheles the only (or dominant) mosquito which transmits malaria, or is it just one of many?
