Nice find: datasheet here: https://media.melexis.com/-/media/files/documents/datasheets/mlx90324-datasheet-melexis.pdf Arduino code for a cousins here: https://www.melexis.com/en/documents/tools/tools-mlx90397---firmware-for-arduino and here https://github.com/melexis/mlx90392#readme PC stuff Prob easier to gut it.

Oh, tricky. Drawing a blank so far, will look up more places later. Got OEM part number?

Ooooh, blue caps!! Shiney! Ain't got nothing for you until you fish out the board and show me the chips, sorry.

SuperCheap auto spade crimp sockets are shit. No spring, loose at the 1st use. Do not recommend.

Pics. Clear circuit diagrams are better. If the input is delta connected, changing it to star would probably get you in the ballpark. Best have a sparky check it.

Send me a pic of it's innards, and I'll tell you how to goose it. The resistor is gonna cost you 12c

2 || lipo, easy. Oh, you can has mains? Well, is 2Fiddy too much? https://www.jaycar.co.nz/13-8v-40a-switchmode-bench-power-supply/p/MP3089?gclid=Cj0KCQjwi7GnBhDXARIsAFLvH4mmOTYQPrmYhm-zriE338bz0AvlewRgMaoQkyPeuknaqPXv3SryrKIaAqK6EALw_wcB

Matter if it's a couple of volts more? 18V 2Ah, $59 https://www.mitre10.co.nz/shop/black-decker-2-0ah-lithium-battery-18-volt/p/269913

@Ned @kempy @P_Star what else we need? DIP switches, some RC filters, Analogue? 103kA SCR drivers for your Rail Gun?

Oops Oh there's why. Who the bloody hell mounts the terminal in the flappy area of the alternator belt !!1!1 ... oh, me.

True, if direct on line starting e.g. 3ph high eff squirrel cage motor. Inverter drive can bring this down to 200 - 300% when slow starting. Pic of motor plate you're having trouble with?

Good point. Is the inverter set to ramp up speed slowly?

Cain't remember if I showed you this? Good practical wiring guide:

Do we need a vaguely car related / electronics thread? (per ^: dang, TOTP)

@Ned or @kempy Topward TOPWARD 6303A Dual-tracking DC bench power supply -working up your way $50bux so far https://www.trademe.co.nz/a/marketplace/electronics-photography/radio-equipment/amateur-radio/listing/4250718955 (sorta temped, but I have 4 bench PSU already and it'll be too heavy to courier, really)

Nice, sneak it lower and put a nut / weld a captive nut to the underside? - oh thread for the oil hole blocks. As you were. Might want a sharper front corner for oil line sealing surfaces? *1. (Ignore*2, I figured it out, you clever man!)

Clean run opposed piston 2T, 120hp from 500cc, nice graphic https://www.thedrive.com/news/company-builds-powerful-500cc-one-stroke-engine-immediately-installs-it-in-a-miata (Oh, the link worked!)

Algodoo to was fun 2D physics modeller/game/ kids edu program, but awkward to edit objects after creation, and no parameterization. FreeCad physics seems to be about static FEM analysis. Suggestions on what to use to make a Dino skeleton out of rods and pivots and springs please ? Meccano? (There's a new CAD input package for Blender, but it looks rather Beta)

Oooh, ooh! Jaycar has naked bulb green and blue neon indicators now!

Bahaha, if you don't start a slush fund for me to contribute to these shenanigans, I shall be frowny face. If that goes stonkingly well; after reading the comments on reducing weight to reduce high RPM stress, you could get the Italian metal wizards to make you titanium rockers, etc? Ceramic pistons?? Oh and bearing speed, oil shear etc, any option to do what the 2T goons do, and throw in roller bearings?

Oooh, punchcard auto phone dialler! https://mastodon.nz/@dan@discuss.systems/110681574669887729

@Roman would be a good man to tag here, but yes. You could closed loop control (means use feedback from some sensor to attain some goal) and have the system strive to give you the EGT you want, or the coolant temp you desire, or exactly 3000 RPM for your gen-set, etc. If you want good hp etc, you may find you need to use an O2 sensor to get a quality of results acceptable to you.

Bugger, - I don't, maybe @Ned or @kempy? If you've a little time, I can con a client into ordering some on their next buy (a month or so). Anyways: (adjusts Barrie (tm) personalised cap): Digikey has a really good parts selector thingy: you can see they have 50 kinds of those family IGBTs https://www.digikey.co.nz/en/products/filter/transistors/igbts/single-igbts/279?s=N4IgTCBcDaIPIDsDKBTAtgSwAQFEDGA9kgAoCCASgNJYCSA4gEIAqIAugL5A these guys reckon https://www.msextra.com/forums/viewtopic.php?t=57426 this goes one OK https://www.digikey.co.nz/en/products/detail/onsemi/ISL9V5036P3-F085/2509749 (though - no thermal protection - probably ok to just chuck a 15A fuse inline?) Narrowing for 400V ish to 100V, and 23A upwards in to-220 and the slightly bigger TO-262-3 gets you these 8 options: https://www.digikey.co.nz/en/products/filter/transistors/igbts/single-igbts/279?s=N4IgjCBcpgbFoDGUBmBDANgZwKYBoQB7KAbRABYwBmMcgDhAMqvMpAF0CAHAFyhADKPAE4BLAHYBzEAF8CAJjAAGCNBDJI6bPiKlwSpQAIAgoxDyqJsxYB0AVisLyj8w9MLYL%2BbBsBOLwDsXnRe-u4gVEbhNC5U8rGW0c7RbmZUntFBmfaxATZZaSHRYWbkUaVgLuTx4eSJpcmlqUwZpQVMRaUlBHblPZXhdjVmdvU9jT3NIHatPe3TnT3dILB9KwNmsMMEsGMrEytTsLMr87CLK8sBawEbBAHbIAF7AQcBUwEnAfMBFwHLdDWdDuIDojzoezoBzoUzoJzoF18a18IN8j18e18B18U18J18iJKnBAvH4AFVxKIeAB5FAAWRwaCwAFdhDhZAplFQEOpUJhcARiJAyFQkYYAGppHES0oGGVMMAOSVMeRGZUUeRK0qReUUKhaphlXWseLq1gGii9Y2rY2A41i9W9NWbOXq2BW9XXZ33D1mJHekA4gPKV0cbh8SAgClU2kMpms9lyEAAWnIPI0WgFumF0yo%2Bt8HBkRaAA Anyways, if your MS is something like the one described here: https://www.diyautotune.com/support/tech/other/troubleshooting-ms-injector-driver/ i.e. has Q14, R37 and Q15 and R38 (current limiting) section and Q3, Q11 sections, then probably most of these will do (287 options) https://www.digikey.co.nz/en/products/filter/transistors/igbts/single-igbts/279?s=N4IgjCBcpgbFoDGUBmBDANgZwKYBoQB7KAbRABYwBmMcgDhAMqvMpAF0CAHAFyhADKPAE4BLAHYBzEAF8CAJjAAGCNBDJI6bPiKlwSpQAIAgoxDyqJsxYB0AVisLyj8w9MLYL%2BbBsBOLwDsXnRe-u4gVEbhNC5U8rGW0c7RbmZUntFBmfaxATZZaSHRYWbkUaVgLuTx4eSJpcmlqUwZpQVMRaUlBHblPZXhdjVmdvU9jT3NIHatPe3TnT3dILB9KwNmsMMEsGMrEytTsLMr87CLK8sBawEbBAHbIAF7AQcBUwEnAfMBFwHLdDWdDuIDojzoezoBzoUzoJzoF18a18IN8j18e18B18U18J18iJKnBAvH4AFVxKIeAB5FAAWRwaCwAFdhDhZAplFQEOpUJhcARiJAyFQkYYAGppHES0oGGVMMAOSVMeRGZUUeRK0qReUUKhaphlXWseLq1gGii9Y2rY2A41i9W9NWbOXq2BW9XXZ33D1mJHekA4gPKV0cbh8SAgClU2kMpms9kyOQrHmiAAm-AAtMoIOH%2BGYeABPLjsyNM5BJoA Octopart is great for finding who has the thing, and at what MoQ and price: https://octopart.com/search?q=ISL9V5036P3-F085&currency=USD&specs=1 Cheers

Fuck 'em

That swarf down on the batt, right of R56?
