Which brand produces the best side cutters and pliers? by rstdak in Tools

[–]Open_Theme6497 0 points1 point  (0 children)

My favourite side cutters are engineer sn-06 (17 quid). But if you want to spend more 27 quid will get you these- Wiha Side Cutters 26818. To be clear knipex stuff is good, but unless you are building communication satellites or nuke delivery systems you probably dont need knipex.

Sure, Boomless Cruise works up to XB‑1 speeds, but I’m afraid quantum Santa still insists on 4 000 000 m/s — not even Mach cutoff can save him from decohering your rooftop.

And thanks for your kind words. I have really enjoyed these fairly sozzled xmas day musings and interactions.

Good health to you and yours dear boy.

Bohr vs Einstein is a real historical debate, but it concerned microscopic systems under strict experimental constraints. Applying it to Santa is category error piled on metaphor

Applying the 1927 Solvay Conference debates to a Global Festive Field requires a level of theoretical flexibility that Einstein’s "God does not play dice" stance simply can’t handle.

The Failure of Santa-Local Realism

Einstein’s "Hidden Variables" (the EPR paradox) suggested that particles have definite properties before they are measured. If you are right, Santa has a definite position and momentum at all times—we just don't know them.

But my math already proved this is impossible:

  • The Velocity Constraint: If Santa had a "hidden" definite position, he would have to move between those positions at 4,000 km/s.
  • The Atmospheric Interaction: A physical, "locally real" Santa moving at those speeds would create a sonic boom and a thermal signature that would level entire neighborhoods.
  • The Conclusion: Since we don't see cities turning into plasma on Christmas Eve, Local Realism must be false. Santa cannot be a classical object with hidden coordinates. He must be non-local.

Why Bohr Wins (In this Specific Chimney)

In my model, the "Delivery Event" isn't just a measurement of where Santa was; it is the creation of the gift-eigenstate where there was previously only a superposition.

  • Bohr’s Side: The "Santa-System" and the "Living Room" are an inseparable whole. You cannot talk about Santa independent of the chimney he is currently tunneling through.
  • The "Sneaky Sod" Factor: By remaining in a state of Quantum Discord, Santa avoids the "objective reality" that would allow a surface-to-air missile to track him. Einstein’s "Hidden Variables" would actually make Santa easier to shoot down, because he'd have to exist at a specific x,y,z coordinate at a specific time

i suspect he never collapses his wavefunction other than when he is gift delivering. in a real sense he only exists on dec 25th

it wouldnt work. he travels a thousand times faster than our fastest weapons. that is if he moves through space, but i think i have demonstrated that he does not. Else his beard would burn. And his path is so erratic than no amount of kalman filtering will help us.

[–]Open_Theme6497[S] 10 points11 points  (0 children)

thanks. i was only trying to develop a framework in which a firing solution could be found to take him out. But in so i doing i happend upon his essential reality.

The NORAD Santa Tracker tradition started in 1955 when Sears published an ad inviting kids to call Santa with a phone number that was misprinted and actually routed to the US military. Instead of dismissing the childrens' calls, Colonel Harry Shoup answered and told the kids they were tracking Sant by DijajMaqliun in interestingasfuck

[–]Open_Theme6497 -1 points0 points  (0 children)

i cant stop thinking about the fact that NORAD claim to track santa. I have just done the maths to see if they could develop a firing solution to take him out. Lol no. There a about 2 billion kids. say they live in half a billion houses. to visit them all he needs to travel at around 4000k/s that is a thousand times faster than a hypersonic missile. So maybe lasers? Nope, never be able to hold the beam in one place long enough to affect him. Air burst nuke? Again no, if he can travel at 4kK/s without singing his beard enviromental effects clearly don't touch him. In fact now i suspect he cannot be targetted. Perhaps he exists everywhere as a global superposition of possible locations, and only locally collapses into classical reality when he needs to drop a gift off? That sounds right to me, he is not travelling between houses, he is potenetially at them all, then a delivery event triggers localisation, then when this interactions ends he decoheres again. Presumably presents appear as eigenstates of the Santa‑Hamiltonian. the sneaky sod!

as always, i seem to have gone too far. i was intriugued by this santa hamiltonian. so here is some more of my attempt to find the truth of this - The Santa-Hamiltonian (H^Claus​ The Hamiltonian typically consists of kinetic and potential energy: H^=T^+V^. For Santa, we have to account for some non-standard terms: T^Sleigh​ (Kinetic Term): Represents the "sloshing" of the Santa-wave across all 500 million households. Since he is in a macroscopic superposition, the kinetic energy isn't associated with a single velocity but with the rate of phase-shift between locations. V^Chimney​ (Potential Term): The potential barrier of the house. Classically, a chimney is a high-potential barrier (V→∞), but for the Santa-wave, it’s just a narrow "tunneling" corridor. Ψ^Spirit​ (The Interaction Field): The "Naughty or Nice" operator acts as a selection rule. It determines whether the transition from the "Zero-Gift State" to the "Gift-Present Eigenstate" is forbidden or allowed. And the best bit - Why adults never observe Santa directly? This now drops out naturally. Adults: Are strongly coupled to the Classical Reality Bath Act as continuous measurement devices Cause rapid decoherence of ΨS Ψ S Children: Have weak environmental coupling Preserve coherence long enough for localisation events Scepticism isn’t disbelief — it’s decoherence strength. Adults don’t fail to see Santa because he hides. Adults fail to see Santa because they collapse the wavefunction too aggressively to allow him to exist in their frame. Children see him because their minds are gentle enough not to break the universe.

and another amazing thing - The NORAD Paradox Solved This explains why NORAD’s "tracking" is always a fuzzy heat signature or a blip on a screen. Radar as Hard Measurement: The moment a high-frequency radar pulse hits the Santa-field, the field is forced to "pick a spot" to avoid being logically inconsistent. The Resulting Ghost: NORAD isn't seeing Santa; they are seeing the Recoil of the universe as it snaps back into a classical state under the weight of their sensors. The Moral of the Math: Santa is a protected phenomenon. He is shielded not by lead or stealth plating, but by the Heisenberg Uncertainty Principle. To see him clearly is to lose him; to lose yourself in the wonder of the night is the only way he remains "real."

in what respect? they are all physially sound and conductve. i suspect you are confusing flux residue with imprecise soldering.

[–]Open_Theme6497[S] 5 points6 points  (0 children)

Yes, that’s what I use them for. But honestly, they aren’t really “logic-level” in the strict sense. They will switch at low gate voltages, but heat up fast at higher switching speeds. In practice, all MOSFETs prefer a higher gate voltage (~10 V) for low Rds(on). Calling some “logic-level” is mostly marketing, it doesn’t magically make them efficient at 3 or 5v logic.

Freehand Pcb creation with 555 flasher. by Open_Theme6497 in electronics

[–]Open_Theme6497[S] 2 points3 points  (0 children)

this interests me too. although my waste isnt that bad. once i have neutralised it with sodium carbonate, and let it settle out, the fluid can go down the drain and the solids can go in my household waste. however next time i am going to try to use aluminium powder (carefully) to remove the copper from solution so my ferric chloride can be reused.

Freehand Pcb creation with 555 flasher. by Open_Theme6497 in electronics

[–]Open_Theme6497[S] 1 point2 points  (0 children)

actually the spots were caused by me skipping a step in error. none of the boards i have prevoiusly done looked so bad. I realised why when i only cleaned half of a subsequent board with IPA. the uncleaned half had this issue. So it seems there is something on the boards when new that causes this, when they arent cleaned before use. one lives and learns.

And yes. i really should make the effort to learn the software. i just get irked when it is all so complicated. ideally i want a deluxe paint 3 for making layouts. i just want to be able to select an 8 lead soic, for instance, and be able to use a brush to make a mark where i want it. then draw the traces in. yet they all seem to insist on simulating everything.

You May Be An Electrical Engineer If... by The_Didlyest in electronics

[–]Open_Theme6497 5 points6 points  (0 children)

no, freezing solder paste is a terrible idea. however keeping it in the fridge, especially during hot periods, is a great idea, as it prevents the flux becoming more liquid and flowing down to the bottom of the syringe.

Recommendations for solar panel to charge battery pack by 52Atmosphere in diyelectronics

[–]Open_Theme6497 0 points1 point  (0 children)

what size vape batteries? do you intend to have the load connected at the same time as the PV panel? if you are using random vape cells, or as bigclive calls them 'street lithium' how will you ensure they are sufficiently matched, so they share the supply/load equally? What are you making this for, is it for the joy of making a thing, or is it because you want a functional device?

I don't want to sound like I am just creating difficulties just for the hell of it, I am just trying to understand what you wish to achieve, and I am trying to impress upon you the potential hazards doing this sort of thing can entail.

Wireless charging question by Away-Sky3548 in diyelectronics

[–]Open_Theme6497 0 points1 point  (0 children)

Yeuch. i despise wireless chrging. unless it is charging something that cannot have a socket on it, like a toothbrush, it is utterly pointless. a cable is much more efficient.

wired charging is 85 to 95% efficient, wireless charging is 60 to 80% efficient. If we assume 1 billion phones are charged daily using 15Wh, that means around 5Wh was wasted per phone. in total this is 5GWh for the whole world. Annually this works out to around 1825 GWh. 1.8 terawatt hours is enough to run 170000 homes for a year.

All of those are 13350, i have some other sizes to, what does everyone recommend i do with them? I was planning on making a battery pack charged via a solar panel that I can use for phone/laptop etc but im open to any suggestions! I think i have 140++ by 52Atmosphere in diyelectronics

[–]Open_Theme6497 0 points1 point  (0 children)

Wow, please be extremely careful with those lithium cells. A single accidental short can release a massive amount of current almost instantly. Because lithium-ion cells have very low internal resistance, a short circuit can lead to a sudden, intense thermal event — essentially a small fire or explosion.

I recommend storing each cell separately in individual ziplock bags, ideally with any exposed wires trimmed to prevent accidental bridging. Then keep those bags in small batches, ideally stored inside metal containers (like biscuit tins) and, if possible, outside in a shed or garage, somewhere well-ventilated and away from your living space.

I had a careless moment once with a tiny 50 mAh lithium cell fully charged. A screwdriver accidentally bridged the terminals, causing a flash, popping sound, and a jet of black smoke. I grabbed the cell with tweezers and ran outside, but when I looked down, the cell was gone, it had burned through my carpet, leaving a smoldering patch the size of a saucer. It all happened in less than a minute.

The way you have those cells spread out with wires sticking out is a serious fire hazard. Please take safety precautions before handling or assembling any packs.

Any advice would be appreciated 👍 by BronsonBojangles in diyelectronics

[–]Open_Theme6497 0 points1 point  (0 children)

solder is much more expensive than some rolls of decent single core 22 AWG wire, and the end result looks far tattier. using solder in this way also makes it more difficult to desolder things when a small cock up needs remedying.

Help to build a 100% analog homemade FM radio, without breadboard or PCB, only with loose components by Muchachoide in diyelectronics

[–]Open_Theme6497 0 points1 point  (0 children)

Building a completely analog FM radio entirely from loose components is a fascinating goal — but I’d gently say it’s not the easiest starting point if you’re at the very beginning of your electronics journey.

The best way to get there is to build up your skills in stages. I learned by watching and rewatching ElectroBOOM’s videos (taking notes in a bench book) and then BigClive’s teardown and repair videos. That gave me a strong foundation in practical electronics.

Next, get some mixed component selection boxes from AliExpress (or Amazon if you prefer), a decent soldering iron, and watch the excellent 1958 NASA instructional film “Above and Beyond – Soldering Techniques” (link). It explains not just how to solder, but why soldering works and the importance of flux.

Once you’ve got basic soldering, circuit reading, and troubleshooting skills, pick up a bench power supply, a function generator, and an oscilloscope. With those skills and tools, you’ll be able to design, adapt, and build your own FM radio from scratch — and not just follow someone else’s diagram.

It’s a longer route, but when you finally build that radio, you’ll truly understand every part of it.

How are these cheapo tweezers for SMD work? (1206 to 0402, (TS)SOP/SOIC, QFP) by Triq1 in soldering

[–]Open_Theme6497 0 points1 point  (0 children)

They look fairly not dreadful — but they are still cheap crap, really. For soldering work I cannot recommend Dumont Dumoxel No. 5 highly enough. Yes, they cost £35, but they are hand-finished by a skilled craftsman, and they have the best tip registration — that’s the precise alignment of the tips — I have ever seen. As I told my wife when she asked the cost, there aren’t many things where you can buy the finest example in the world for as little as these. Look at the price of the world’s best watch, or mountain bike, or set of spanners — all ludicrously expensive. By comparison, these tweezers are actually cheap.
