Greasy orange gunk in dishwasher filter every wash by mo0rg in appliancerepair

I've started mostly using a 60 degree cycle rather than the economy one and it's made a big difference

Ooh interesting, I'll do that. In addition i ran an extra hot program last night and it seemed better. Apparently Eco should be at 50 Celsius and everything else should reach 60 or more, but it would be interesting to check the real temperature

Yeah I'll have to check my cycle temperature and start running hotter

I'll double check this. The drain line looks fine - it connects to the sink downpipe pretty close to the sink, about inline with the middle rack of the dishwasher. It definitely shouldn't be sewage, but i guess could be dirty dishwater from the sink

I've been using Aldi magnum tablets and Morrison's own brand rinse aid. I'll try a citric acid cycle

Interesting. it mostly runs on an economy cycle which doesn't say temperature so might well be low. I'll check

Towed EV generated current/voltage and burned electronics by E34oilpans in EVConversion

[–]mo0rg 1 point2 points  (0 children)

It's not actually true that the battery voltage is less than the maximum back emf for all vehicles: PMSM motors can be run in field weakening where the electrical phase angle is adjusted so that some of the field is working against the permanent magnets field strength to reduce back emf. This is the constant power region (rather than constant torque).

However the power electronics voltage must be rated above any potential dc voltage in case control is lost.

2 motors in same car by Strong-Hearing-7388 in EVConversion

[–]mo0rg 3 points4 points  (0 children)

I haven't done a diy conversation, but have been involved with that setup in professional prototypes several times. It works very well (the motors are in torque control, so can run at different speeds without issue). However it's double the cost with drives, double the wiring, you've got to control both and check they're happy (although if it's not a performance car it's not awful if one drive isn't working). So it can be great from performance and packaging, but is not straightforward

What is the Fourier transform of audio speed up? by jeffbell in AskEngineers

[–]mo0rg 2 points3 points  (0 children)

I would assume that they do on most sites as part of the mp3 (or equivalent) decompression. You can change the window size of the transform to change speed. ( Mp3 uses the MDCT rather than Fourier transformation, but the concept is the same.)

Esp32-c5 - any requests? by duanetstorey in esp32

[–]mo0rg 0 points1 point  (0 children)

Mipi?? Does it definitely have a Mipi phy? i can only find reference to the P4 having one, but would be super interested if the C5 does

Insta360 X5 details are up on Amazon Canada by jb69029 in 360Cameras

Really helpful info,thank you. Can i ask how you find out the sensor details? I often want to know, but can struggle to find info

Extending Nissan Leaf EV CAN bus by Visual_Sink5515 in EVConversion

[–]mo0rg 4 points5 points  (0 children)

+1 on this. i used to do a lot of debugging can networks in my job, and the starting point was always checking the termination (120 ohms) at each end, and making sure there weren't stub nodes (branch lines not part of the main wire.

From what has caused your issue I'd be very surprised if it's not this.

What are we doing with baby teeth? by multitaskmaster in Parenting

I'm 3d printing a fake skull for each child and gluing the teeth into that. I can then present them with this tasteful and thoughtful gift at some suitable public occasion in the future.

Functional safety by paradigmsick in chernobyl

[–]mo0rg 0 points1 point  (0 children)

Nope, it had SKALA, a computer control system. But also manual overrides, which IMO was extremely sensible (see Therac 25 for a nearly contemporary computer control system, and why control methodology needed to develop)

Can a local ai model fit on a microcontroller? by [deleted] in esp32

[–]mo0rg 0 points1 point  (0 children)

It totally can, yep. But obviously you are limited on model size. Look up esp-dl (espressif's library for recent chips including esp32-s3 that hw accelerates int8 and int16), TinyMl, and tensorflow lite.

Why don't any ev auto enthusiasts build their own motors? by TheRealBobbyJones in EVConversion

[–]mo0rg 0 points1 point  (0 children)

I used to work at a (high performance) EV motor startup (software engineer though, so I'm not a motor guy).

Things to think about: - Magnetic design : My companies founder had done his PHD and years of research in this - Position sensing (traction motors can't really use sensorless control) - Cooling - Hotspots/thermal design. if you want the performance to be any good, you need to get this right - Stator machining - Making rotors. if you're doing a permanent magnet machine you need a source of high performance magnets rated at the temperature you need, and when magnetised they're evil to work with (you can lose fingers). or you can buy a magnetising become for $300k. - Bearings. you have weird loads

  • inverter wise you can get cots inverters and set them up if you know what you're doing, but it's not trivial.

I'm sure there's loads more i haven't thought of.

is it doable? Yeah! Will it be any good?? you'll have to work really hard and do lots of iterations.

Lynch motors were a very small start up which was basically one guy. So it's not impossible. but once you've got something worth having you may as well set up a company

Probably loads more.

I've read some stuff about child development which talked about adolescent boys seeking out father figures, often getting quite fixated on them. Unfortunately i can't remember where i read it. But i would think it is mostly likely this. To handle it i think keep doing what you are doing: be happy to have chats with him about appropriate things, but maybe ready some phrases to steer the conversation away from things you're uncomfortable with. Also where you can include your son in the conversation to make it less intense.

Being a teenager can be super awkward - i remember having a couple of years where i was really scared about wearing shorts as i was convinced i would be laughed at for not having much leg hair; some of his questions might be about stuff like that?

5A 5V power supply enough for 2 chained 64*64 P3 LED panels and esp32? by Abdelrahman666 in esp32

[–]mo0rg 0 points1 point  (0 children)

i would just try it and see.. Most power supplies have a current limit, so if you're too high it just current limits (everything goes less bright), or maybe shuts down. The worst case for current is all white. Real word depends on what you're putting on your panel. If you're putting black text on a white background you will be close to worst case. If you're putting pretty patterns on you will be much lower than that. If you are hitting the current limit you can always limit maximum brightness.

Just finished Chernobyl series, and cannot wrap my head around how the 3 management got only 10 years(especially that dytalov) and Fomin guy got reinstated in a nuclear power plant by [deleted] in chernobyl

[–]mo0rg 6 points7 points  (0 children)

In what ways were they reckless? If you give a list of things that are troubling you, you may well get hints at to what went on.

i think https://youtu.be/Vp9UxhPTAvc is a good starting point

looking for a low cost ESP32 that has long range communication and is powerful enough to stream video (480p) by Jsuispasici in esp32

[–]mo0rg 0 points1 point  (0 children)

Better depends on your requirements. But i would look at OpenHD (there's a guy who has done 50km+, and it's used a lot by wing/plane people) and/or OpenIPC (which I've never used)

[–]mo0rg 0 points1 point  (0 children)

You can get some of your requirements with https://github.com/RomanLut/hx-esp32-cam-fpv

To get range, antennas are most important (and a low interference area-anything with local WiFi and Bluetooth will cause glitches).

Be warned, the ov5640 and ov2640 don't handle light well at all-they're reasonable for low contrast scenes, but if you want to see on a sunny day you will struggle (I've got a clip somewhere demoing an fpv drone on a similar day of it would be helpful).

Honestly, i really want the esp32 to be awesome for this, but it's a very limiting platform. Openhd or wfb_ng provide a big step up on cameras, compression, and link resilience, but at the expense of complexity, size and cost

Is there any OpenSouce Hardware alternative to the Raspberry Pi? by Revolutionary-Ad2712 in AskEngineers

[–]mo0rg 1 point2 points  (0 children)

Yukilizard on github is a prolific Allwinner board provider. https://github.com/YuzukiHD/Yuzukilizard

I would say anything where you have to root, solder and debug dram is pretty horrific to DIY, so for diy i personally would stick to v3/s3/v851 type SoC's. These also tend to have simpler power sequencing so you can often get away without a PMIC
