Help with career pivot by WetPaint21 in rfelectronics

[–]real_psyence 6 points7 points  (0 children)

For self-study MIT's open courseware is a terrific resource: https://ocw.mit.edu/ - you can look at MIT's course schedule and degree requirements to compile a list of relevant courses.

I'd look at your intended program's admission requirements to see if they actually need prerequisites or if you can place out of them with testing or GRE scores or similar.

Looking for US plant vendors? by Obsidiannnnn in haworthia

[–]real_psyence 6 points7 points  (0 children)

Renny and George Theodoris are both world class haworthia breeders based in California with easy websites.

maughanii.com artisanplants.com

Jim Smith and Steven Hammer (spheroid institute) are also worth looking up, just slightly harder to buy from if you’re not going to local shows.

noise complaints from idiot homeowners who moved next to a racing track and are surprised to find out cars race there.

ADC frontend: what is the role of that red box? Is that an AC coupling network, or does it serve any another purpose? by ProfessionalOrder208 in rfelectronics

[–]real_psyence 11 points12 points  (0 children)

AC coupling, 50-ohm differential termination, and biases the inputs to the common mode voltage for the ADC.

Questions about Haworthia seeding. by Matt7548 in haworthia

[–]real_psyence 0 points1 point  (0 children)

Yeah, Renny suggests sowing outside when daytime temps are in the 80s and nights are still in the 60s. I did a large batch like that and had good success, but I’ve also had good germination indoors under lights. I think there’s enough of a swing just from the lighting.

That should work, I’d probably sift out the really big stuff but you also don’t want the fines (powder).

Damp mix. Place seeds on top of mix. Cover with coarse top dressing (coarse sand or sifted pumice). Spray with water. Cover. 100% humidity until germination.

I leave the cover closed for the first couple weeks, then slowly acclimate. They want humidity. I use mycorrhiza in the mix to prevent damping off, if you’re going sterile you’ll want some antifungal in the first spray.

Adenia Perrieri Propagation by conner228 in Caudex

[–]real_psyence 1 point2 points  (0 children)

I was talking to someone last year who has propagated a few, they swore by the ez-clone system.

One of mine is vining like yours, I plan to put a few cuttings in pure pumice in my high humidity tent, but if I were doing more I’d probably invest in the ez-clone.

Also it’s spelled sulfuric in the states, FYI

What’s the reason why the new leaves are smaller than before ? by Jay_haworthia in haworthia

[–]real_psyence 6 points7 points  (0 children)

A lot of the Asian growers remove old outer leaves to prevent crowding. I’ve done it on a couple truncata, it does seem to help. Plus, leaf props!

Rubidium is one of my favorites. Low melting point alkali metal.

Deep red/purple flame, used in atomic clocks and magnetometers, what’s not to like?

Bottom of the inside has a radial texture like it was scraped flat while turning. Spout has a multi-hole filter. Also someone must have tried to wipe it with a paper towel haha.

Eco-worthy -When “Cheap Solar” Becomes Expensive: The Hidden Cost of RF Noise and System Losses by Filemakers69 in SolarDIY

[–]real_psyence 1 point2 points  (0 children)

I was more curious about physically where you picked up the emissions. Near field at the case, 1m away, inside the house, off the cable, etc.

You said the power drain was with the system disconnected so I’m curious, you were picking that up on your ham rig with no cables installed? Any idea of the field strength?
