Have a squizz, see if the drive current is different. If so, then setting up a constant current drive for each might even up the speed

Gas dowser. It blinks, it beeps. What more does a man need? Led at each end changes colour as each gas level rises, and the highest side blinks. It beeps a tone depending on average gas level, (warmer, cooler) to help localize source. I've realised the LPG sensor can be swapped out for ammonia, etc in the same footprint

Ah. piss.

ahem:

Anyone got info on these dual fuel carbs? (diagrams / theory of operation etc?) I'm pondering if they'd meter hydrogen. https://www.trademe.co.nz/a/marketplace/home-living/outdoor-garden-conservatory/lawnmowers/parts-accessories/listing/5006589801

Yeah I bounced it to a random port. Once you got NERD-LEVEL networking, all it takes is ONE little hole :-D

Jeeezuz @locost_bryan or whoever the ISP nerds are lately. Where's the secret list of ports that One/Voda/iHug etc block these days (which includes port 1194 if our openVPN is playing nice). Conclusion. My openVPN is no longer playing nice. Fuck those guys

@Hemi anyone use Diesel or kero as outback emergency Hydraulic?

Wild arse guess: Any chance of stuffing the 24V pump into the Ram for an empty lift to get to the rest of the wiring/tubing hoo ha under teh deck?

Win the rocket thrust race by first winning the chemical hazard chart bingo game: 18:11 " If this engine were actually used in a stage 1 booster, it (exhaust) would douse the launchpad in a toxic acid capable of dissolving sand... "

oof, whassit doing / not doing?

Oh good, I understand the assignment (eventually)

Ah, run your relay off the NC terminals of the limit sw for the first stage parallel to the motor, so it switches off with the motor at the limit, then you have the NC terminals on the relay will relax closed, to drive the next thing. You'll have those NAND/NOR/1 bit sadder gates going in no time!

Sounds like Nick might be on to it with DPDT? Use one NC to common terminal to open at limit, then the other common to the other NO terminal, which closes to enable your 'next, Go!' signal? Or 2x SPDY limit sw if they don't do DPDT? Of course, if you supply full cad drawings and all your Arduino code, I pinky promise I won't steal them and get zillions made in China Oof. I did a reading fail. How much coil current becomes a problem? Is 10mA for an SS relay too much? Also, I think there are set/reset relays that only consume energy at change?

It's close: https://media.digikey.com/pdf/Data Sheets/NXP PDFs/BUK215-50Y.pdf It's just a switch, Input on, output on, unless faults.

These days, 25A rectifier, a few thousand uF capacitor and a cute little AliExpress switch mode Buck regulator: easy.

Watch for the 70s / 80s Suzuki regulators (eg RG 250). They had the 3 phase rectifier, then each cycle when a phase reached regulating volts, they'd just short circuit that winding with a big fat SCR (a solution with cheap electronics parts). Fine if the gen/alternator is designed for it, just makes a bit of heat in the wire/regulator - not sure how you'd check a random gen is suitable for that...

I do have a 1/2 built prototype design for a round-robin load-sharer, exactly for running multiple freezers etc off a limited supply. E.g, drop the freezer when you hit the microwave, then restart the same one while the compressor is charged, then after the first one reaches temeperature set-point, start the next one .

Yeah, as your daughter noticed, it's running a bit oil rich; which I could fix, but, maintenance... *Shrugs in Italian* Oh I have plans for this POS motor once it's out! Compression ratio only counts above the exhaust port, amirite?

Sounds good, but check the power limits - draw too much, you may find you discharge / damage the 12V, which will then be tricky to see once the HV to 12V tops off the (now weak for current) 12V battery

Oh - it was starting to run shit because of ... plugs! Who'd a thunk? I should really put the good motor back in.

Yeah, it's super tiny. It was the wrong size 0.66 inch, so about the size of my thumbnail. Then I fitted the WIDE-SCREEN one. 0.96" so a little bigger than my thumbnail. It's playable if you've got OK close up vision (old man). There's a 1.36" (?) on e on AliEx, might work?
