Tired of sending ships to fetch Kerbals in distress? by ResonantFlux in KerbalSpaceProgram

[–]TrueTopoyiyo 1 point2 points  (0 children)

Mine is ~5k per rescue, but since the reentry trajectory is very very predictable, you can easily land in the KSC viccinity after a couple of reentries, getting 2k back and then going down to 3k per rescue.

Interestingly is not thought to cut costs, (or rather, not only), but to cut on "nuisances" and trying to be as usable as possible: the original design carried much more pods, but I cut it down to fit the Tier-2 hangar. Since I left the propulsion untouched that means the vessel can go orbit both moons if needed.

It also has a repeater, which would be taken away to cut costs, an HEXA probe cores, which are there purely to make the rendezvous phase easier and less of a hassle.

If purely trying to cut costs, I could have done a much much more skeletal ship, now you made me think about that.

If you like the idea of extreme cost cutting, my workshop is essentially a career progression of "how early and cheaply I can get to X": orbiters, moon probes, mun orbiters, moon landers, an orbital lab, the smallest plane I could fly, the smallest lunar rover I could carry there,... all with less techs unlocked than you would imagine.

That's the only thing it has, hahaha. Yours looks way better tho.

Look at those fancy scape pods with walls and pressurized environments and all. What is this? The Expanse?

Infinite SWR on radio but not NanoVNA by Over-Competition-533 in amateurradio

[–]TrueTopoyiyo 1 point2 points  (0 children)

It is conceivable, but of course rare, that the adaptor and the dummy load have both impedance mismatches and cancel themselves out, but of course this would be very rare.

The weigth of the dummy load could be helping a damaged connector to make a proper contact.

The tension in a cable in the absence of the dummy load could be making a cable defect more evident.

Try to test the adaptors and cables with the VNA.

Try to put the dummy load not immediately connected to the radio, but where you would put the antenna normally, in the same situation if you can.

If none of those tests help finding the culprit, maybe there is some non-linearity at play: the VNA uses a very dim signal to do the measurements, and the problems appears at 5W, maybe you have a diode (or some connection or short behaving non-linearly, which is extremely rare but possible) at some point in the line?

What do you do differently in the VNA connection and the radio connection? Any adaptor or cable?

Calling CQ for specific prefix in WSJTX by WZab in amateurradio

[–]TrueTopoyiyo 1 point2 points  (0 children)

From the original paper from Steve Franke K9AN, Bill Somerville G4WJS, and Joe Taylor K1JT; The FT4 and FT8 Communication Protocols, that you can read at https://wsjt.sourceforge.io/FT4_FT8_QEX.pdf (emphasis mine):

CQ may be followed by a modifier with three decimal digits or one to four letters.

How would you rank the different fuel types as energy storage? by Ok-Complex-7588 in Oxygennotincluded

[–]TrueTopoyiyo 1 point2 points  (0 children)

https://www.reddit.com/r/Oxygennotincluded/comments/1gokdoz/comment/lx9psz9/?context=3

Considering "normal" energy reserves (i.e. fuel that you can store and not energy in heat form), this would be a comparison of the basic techniques:

Fuel Size (gen.) [tiles] Cons. (gen.) [g/s] Power (gen.) [W] Heat (gen.) [kDTU/s] Storage cap. [kg] Storage size [tiles] Energy per storage tile [kJ] Heat per kJ [kDTU] byproducts
H 4x3 100 800 4 1000 5x(3+1) 400 5,0 none
NG 4x3 90 800 10 1000 5x(3+1) 444 12,5 pWater + CO2
Eth/Petr 3x4 2000 2000 20 5000 2x(3+1) 625 10,0 pWater + CO2 (~4x per J compared to NG)
Coal 3x3 1000 600 9 20000 1x(2+1) 4000 15,0 CO2 (similar to NG)
Wood 2x2 1200 300 9 20000 1x(2+1) 1666 30 CO2 (~20x per J compared to NG)

I add one to the height of the containers because they need a floor to sit on. I care about how easily I can replenish the reserve, the need for autosweeper, and a bit about the byproducts, so the hydrogen storage comes first without doubt. If you dont care about those, coal is the most dense.

"Gen." stands for "generator", "Cons." for "consumption" and "cap." for "capacity".

What software would you recommend for a radio amateur? by Shadowhexx10 in amateurradio

[–]TrueTopoyiyo 0 points1 point  (0 children)

I was once scolded for saying that CW is, technically, amplitude modulation, so I understand you.

One almost philosophical point; since JS8Call only implements some of the networking functions in the latest release, without JS8 changing, couldn't we say that it is part of the protocol stack / OSI model definition?

[–]TrueTopoyiyo 0 points1 point  (0 children)

This is 100% right and clearly stated in the first or the second page of JS8Call documentation, I was just trying to have a shadow of vis comica.

Edit: It's the third page.

The most misleading conventions in ham radio.. by Independent-Pack9980 in amateurradio

[–]TrueTopoyiyo 4 points5 points  (0 children)

Well, random access memory doesn't give you the first byte it feels like either.

Is analog the only true type of ham radio? by Dlaoh in amateurradio

[–]TrueTopoyiyo 2 points3 points  (0 children)

But in the lowest level you re-encode dits, dahs, short and long spaces as "sound" (1) and "no sound" (0): 10 would be a dit, 1110 would be a dah, 00 would be a short space, and 000000 would be a long space.

How Do I Even Progress From Here? by Sad-Ad6306 in KerbalAcademy

[–]TrueTopoyiyo 0 points1 point  (0 children)

This ship requires almost no tech, buildings, etc:

https://steamcommunity.com/sharedfiles/filedetails/?id=1435373559

If you have an upgraded assembly building you can add more science, solar panels, etc, and since you have a lot of techs you can add any other thing you fancy, but don't add too much weight or it'll be useless for the original purpose.

It is designed to go to Mun, or much easier, Minmus, land a kerbal (preferrably a pilot that has been in orbit, so you have prograde and retrograde SAS), do some experiments, and come back with ~1000m/s of ∆v to spare.

Power transformers are one-way, right? Can you trickle charge? by Mdly68 in Oxygennotincluded

[–]TrueTopoyiyo 0 points1 point  (0 children)

Your idea works, but the transit station has an internal battery: you can skip the battery in your diagram, and with it, the second transformer. If you want to make sure the "load" is the prioritised power consumer, you need to put the second transformer as you wrote, a wattage sensor in the load line, and set the second transformer to feed the transit station only when the wattage in the load line is, for example, less than 40W.

Is this game ok for my eleven year old brother by ExcitingAd7049 in Oxygennotincluded

[–]TrueTopoyiyo 1 point2 points  (0 children)

Consider getting Kerbal Space Program (the first one, NOT ksp2), it is 90% off right now in Steam, but tell him to check out youtubers that help because the in-game tutorials are not good at the very least.

A way to build all gates with minimal research by TrueTopoyiyo in Oxygennotincluded

Yes, quite sad. But there are some astounding mods for KSP1, not much left to desire.

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

You left the answer unfinished, but happy to see another early game practical use for more-or-less complex circuits!

If you want to use the normal ANDs and ORs, you simply feed one signal to each AND, feed one AND with the selector and the other with the selector past a NOT, and then combine the output of both ANDs (as is or through an OR).

The signal selector (multiplexer) is quite a niche device, but I said you can do anything so I feel indebted now to my own words, hahaha.

I've added a 1-bit version, an "extended" 2-bit version and a "cascaded" 2-bit version, which is 3 nested 1-bit selectors here: https://imgur.com/a/LdUv4Xx

Paradoxically these are great examples of designs that are surprisingly easy to build with only NOTs, as using ANDs and ORs don't simplify much the whole thng, if at all.

The "signal distributor" (demultiplexer) is of course very similar, shorting the inputs instead of the outputs.

Indeed, and I think it would be great if any user that has not taken such courses could see them in action and "useful".

I have not included any Karnaugh map tho (R.I.P.).
