I don’t think that adds up… For one, the resistance going down means less current flowing through the resistor. For two, for the voltage to be high enough to harm the body at those currents, those would have had to be completely insane meters. Our bodies routinely handle thousands of volts whenever we feel a static discharge. It’s not a problem since the current is extremely low.
E=IR, where E is voltage, I is current, R is resistance.
At lower resistance in the test material, since the meter operates at a fixed voltage, there is greater current flow causing more deflection in the meter (assume analog meter, though the input circuits of a digital meter operate on similar principles).
The ‘resistance of a human body’ is about 30,000 ohms, but that is really about 15,000 ohms for the skin at either end of the current path. Pressing ‘thins’ the skin, lowering resistance. Puncturing the skin makes a circuit of metal probe leads and ionic solution, dropping resistance to near zero. As resistance approaches zero current goes to infinity, allowing even the typical nine volt battery of an ohmmeter to produce a fatal current flow (hypothetically, did not test this part).
I’ll see your ‘Wired,’ and raise you a
Considered to be one of the hardest computer games of all time…and a terrific education in electronics. There’s a ‘play on line’ ‘modernization,’ but I haven’t tried it. Yes, I am old enough to have played the original.
I played a lot of MS DOS games but missed that one. Wonder if it can still be found.
I lied.
This turns out to be the original game, just running on-line, not ‘modernized.’ 1985 graphics and all. Made me shudder. This game was popular among the nuclear reactor operators that I was running with at the time, and no one I ever met could finish it, including me. The first few levels are immensely satisfying, because they are hard enough, but once you get to where the robots need timing circuits precise enough to synchronize their movements…yeah, I was not good with failure back then…
ok thanks! But yeah. I will have better success with the Wired game in the YT video.
Edit: Wired is FREE on Steam
Uh, I highly doubt that… Isn’t resistance usually determined by passing constant current and measuring the voltage? I guess it would work the other way around too, but a meter constructed that way might erupt into a merry little fire every time somebody accidentally shorted it… (or at least need a breaker replaced).
There’s no such thing as a volt meter. All meters measure current - but by measuring the current flowing through a known resistance, the voltage can be extrapolated - and that’s what voltmeters do.
Similarly, by passing a known voltage through an unknown resistance, the current reading can be extrapolated to give the value of the resistance - and that’s what ohm meters do.
And the old-fashioned AVO meters from 50 years ago weren’t auto- ranging. If you tried to measure a voltage or current higher than you had the meter set to, you could blow up a very expensive instrument - or at least blow all the fuses.
Confusing, isn’t it?
Well, this is turning out to be a refresher on my veeeeerry little used electricity knowledge. I hadn’t expected that here, but it’s by no means unwelcome!
Well while you guys debate that, I did this in Indiana Jones Crazy cogwheel puzzles. A couple of them were quite challenging.
Boy am I glad I found this Robot Odyssey Rewired thing…I am through the first puzzle of the second level and feel like I got kicked in the brain by a horse…
@sheralmyst , You have persuaded me.
Given that nothing of note is going to happen to No Man’s Sky until some time in February, I have taken your enthusiasm on board, and bought Indiana Jones.
So far, it’s very pretty.
I am on my second run. Hope you like fist fights cause guns are fairly useless in Indy’s hands, except as a club.
I am attempting to reach every item and snap every pic in one run. So far, there is only 1 item I know of that I cannot get and it requires a key from each main area. Not entirely sure how I get those…
One hint, when you reach Sukhathai, you will encounter wooden cogs. The small ones can be taken with you. Take every small wooden cog you find and do not leave them behind. They will be used in multiple places. Yesterday, I thought I had completed all uses and left mine behind in the jungle…and I don’t remember where…so, I also highly recommend supplementing the in game map with some notes of your own.
So far, I’ve only got as far as the Vatican - but I’ve already discovered the combat peculiarities.
Woody Guthrie’s guitar used to carry the message “This machine kills Fascists”. I suspect even he would have quesstioned its suitability on an umbrella or a fly-swatter. And I hit a guy once with a monkey wrench, and broke it. Some hard skulls, these Italians.
Hand bells thrown from a distance and precisely aimed. I highly recommend it for a laugh.

Thanks! Interesting topic: Game devs have to manage expectations and make tough decisions which features to include and which to drop.
I’ll follow SpaceCraft news, but I don’t intend to buy the EA nor preorder. They are not even at a stage yet where they could show gameplay.
It’s being compared to Space Engineers, I’d be curious to be shown the parallels. SE can handle only a few dozen players per server (SpaceCraft expects 1000). SE lets you craft, build physical ships out of blocks, fully detail the shape and interior, and walk inside and on the hull (!) of any ship or vehicle even while it’s moving (!), plus basic terraforming. (SpaceCraft hasn’t shown their take on these details yet.)
For comparison, SE just announced their EA release of SE2 for a similar date. They have 10+ years of experience having produced 3 games (2 no longer receive updates). They’ve been building a new engine for 5 years before they even showed it to anyone. They can currently livestream creative mode in game, and they can show tech demos of e.g. talking NPCs and water flowing on planets.
That’s what I consider a realistic state to be in, they have a head start and they promise only features they have experience in. And it will still take a few years for SE2 to progress from EA to full release… That’s the maturity level that I compare other games (like SpaceCraft) to. Let’s see what SpaceCraft announce next and what an in-game demo looks like. Currently, they promise less than SE2 (no terraforming, no water, no console support, no singleplayer, no modding), so maybe they can do it.
If SpaceCraft have less experience and promise more, I’d be sceptical. That’s kinda what is happening with StarCitizen (to which these games are also being compared). The SC dev team was much larger but had no coherent experience, they started writing and rewriting the engine under the public eye, and they promised a lot more (1000s of players, single and multiplayer, missions, full physics (!) down to elevators and “persistent cups”, dynamic economy, talking and interacting NPCs). On the other hand, SC doesn’t support custom ship building, consoles, or terraforming, which makes certain things easier.
PS: Then there’s the difference whether a game is indie/self-published or dependent on a publisher (who can just decide to dump it). I think the above three are all indie? And HG are indie (but Sony wrangled control over the console release?)…?
