Re: First oscilloscope thoughts

Yeah, looking at it more closely myself, it looks fairly MEH....like one of those things you grab off Ali, but what you pay is what you get I guess.....

Thumbs up Re: First oscilloscope thoughts

Yes, but it's about hacking the DS1052E to do 100Mhz (https://www.youtube.com/watch?v=LnhXfVYWYXE) LIKE the DS1102E I'm trying to get. Not sure if the same can be done to this one to bump it even...

Talking Re: First oscilloscope thoughts

4 years later and yo' boy here is still struggling to get his first scope :D

I'm browsing a local site for second-hand ones, since there's no way I can afford a new one that's got decent specs...

Thumbs up Re: Remote pump control ideas.

A quick mod of the snippet I posted earlier: THIS is what I had in mind with those two separate supplies. The suffix _CON is for the "dirty, noisy, nasty" control side of things and _MCU is for the...

Re: Remote pump control ideas.

I know what it looks like :) I was more curious if it should have a specific value/size...etc or if it's enough to be in the ballpark.

Can I harvest this from some random sh!t I find around the shop ?

Talking Re: Remote pump control ideas.

Ok, more things we tried today, to little success.

I first measured the green PE conductor and it appears to be connected indeed - I get little resistance between it and the blue neutral wire and...

Thumbs up Re: Remote pump control ideas.

I'm pretty sure it's a TN-C system, so there's no dedicated earth stake (PE=N). I can't get to the pump itself, since it's below ground under an access hatch...doesn't matter. There is an old rusty,...

Ok, time for more details, since it's getting interesting :D Here's a picture of the box holding all the high power parts, including the contactor. In the original setup, their power supply was in...

Re: Remote pump control ideas.

I've always been afraid of these, though I KNOW what they are and they SHOULD be used, but don't know how to DESIGN them.

The three phase Siemens bastard is a 230v coil and the smaller one driving...

Unhappy Re: Remote pump control ideas.

So: replacement board arrived, we messed with it some more on the bench and my programmer buddy managed to comb through my original code and mix and match stuff to make it a bit better, both in terms...

Re: Anyone got a Scribd account to help with schematic ?

Ok, I replaced all of the components with "fresh" ones and tried to power it up. I connected the battery pack and used a 60w lightbulb in series with the mains plug.

I plugged the mains in, with...

Re: Xbox One dead LAN IC

Just stumbled upon this vid (https://www.youtube.com/watch?v=C2rfmqvwez0) where the chap pretty much does it for me: towards the end, he removes the chip from the board entirely and he gets exactly...

Talking Re: Xbox One dead LAN IC

No network transformer that I can see, so it must be built into the RJ45 connector...

It's worth mentioning it DOES respond to the touch-key being pressed. White LED comes on on both the box and...

Re: Xbox One dead LAN IC

Just in case someone was curious about the outcome of this story: I got the chips from Ali, soldered one on, but the problem persisted: same boot-loop as before. I'm not sure if the chip was not...

Re: Remote pump control ideas.

We hit a snag yet again (this project's just not meant to be): the board which had died the first time which I fixed, died again today :(
This time, the chip appears to have shorted out, because I...

Re: Remote pump control ideas.

I can now definitely confirm there's a power issue messing us up. There's some situations in which the client board locks up and no longer loops and these can be replicated each time, so they're too...

Re: Remote pump control ideas.

I will not even run the relay through my "filter" here - just the Nucleo. I sure hope my changeover idea is "decent" enough :D

Re: Remote pump control ideas.

Good idea. I DID plop a single diode in series with the supply to the board + a single electrolytic, but I guess I should be increasing that capacity, add ceramics too and switch over to a FULL...

Unhappy Re: Remote pump control ideas.

Thinking the power situation at the tank side is a bit funny with that whole "power coming on at night and going out in the morning", I thought I'd update on how I ended up working around that too....

Red face Re: Remote pump control ideas.

True - I noticed in Cube or whatever, you have to define EVERYTHING, every "device" like SPI or Ethernet requires explicit code to be added - NOT beginner friendly indeed, but a lot more powerful in...

Re: Remote pump control ideas.

As a refresher, to bring this discussion up to date again, we are using two Nucleo144 boards. The chip on them is the STM32 F767ZI. We're doing the code in Arduino's IDE. I know ideally we should be...
