Which information are you using to wire up? The resolver connection doesn't go to the Zombie Board, the inverter will want that.

The stm32 is clearly unwell. Without showing clearly what was connected where no one will be able to say what you've done wrong. You might get lucky and replacing the stm32 might be the only dead component

You can do a power up test without connecting anything except the 12v+ and ground. It’s best to use a bench power supply rather than a 12v battery for testing. With the power supply you can limit the current, then if something is wrong it won’t do as much damage.

Sorry to be a pain and I understand that you have a number of "irons" in the fire. As I said I can't view the "Improved zombie" of October 28th video despite being a patreon so I do not know where things stand. I also note that the VW charger video has appeared on Youtube despite it being made after the mystery video.

Have recently purchased the zombieverter vcu from Damien and had it assembled as per video but still have to fit IC 10 as not supplied in the kit. After connecting the resolver cables and doing a basic power check using 12v volt battery the micro controller IC 8 started giving off smoke signals so I quickly disconnected. Where have I gone wrong.20221106_204748.jpg
I am using the lexus 300h and inverter.
Thats super weird. As i mentioned on the email I power test every board and in fact have to apply power in order to load the software. Even connecting the 12v in reverse would not cause this sort of a failure. I'm happy to replace a board foc if its a manufacture or design flaw but sadly this looks like power or some other signal may have been applied to the wrong pin or pins. We'll sort something out and get you a replacement or a repair but I'd rather know the cause least it happen to anyone else. e.g. have I misdescribed or mislabeled a pin in the wiki videos etc.

Maybe photos of the Zombie connector and the inverter connector annotated with the signal would help also, incase those aren't correct

Also do a dc volts check between ground and your inverter signals in case the inverter is bad and killed the vcu. I recently helped a customer with a 6 month problem that we ultimately chased down to a water damaged inverter. He'll update the thread with details himself.

So I had an incedent with my GS450 inverter and Zombieverter. This was entirely due to myself and not the kit.
Not as bad as Damiens Panzer troubles but expensive just the same.
It seems that the capacitor dishcharge resistor inside the GS450 inverter was blown and so the inverter would not discharge even after a day. This indirectly led to me accidentaly shorting my HV sense wire to the Shunt because the inverter was still full of HV. the result was a blown shunt and a blown Thunderstruck master BMS. Having replaced these units I now find that the zombieverter, IC 11 XL1509-5.0e1, has expired. see top of picture.

Unfortunately I am not an electronics person and do not have the skills to check out the ECU and it seems that there are no XL1509-5.0e1's in the uk. Does anyone know where I might get one and also someone who could fit it and check the Zombieverter for me.

Thanks

It is difficult to see detail in the photos as transmission + inverter are placed in a tesco shopping trolley.

If you're not able to use all-unique wire jacket colors (usually not an option; OEMs use stripes/bars to double the available options), then I recommend using wiring lables at BOTH ENDS of each wire for at least the fabrication stage. Numbers or descriptions, your choice, but it's very easy to mis-wire harness connectors when re-using colors.

Well . . . it's not required but mis-wiring connectors is a common harness misteak, and is so easy to do that triple-checking is the baseline here. One person checks twice, and a separate person also does a single check, at a minimum. On our equipment, wiring mistakes are more expensive than just a ZV board :(

You'll need to go back over those wires and double check and do a voltage test as I said earlier to ensure nothing is wrong in the inverter that caused the board to fail.

Just to let folks know that V1a boards are now shipping with the Wemos wifi module. See the pictures here for fitting information. Can someone please add to the wiki? The Olimex header is still there for those who may prefer that option.

If you can get a replacement ic but dont want to do the soldering and fix up that track I can do that for you

Thanks Bigpie, that's very kind of you.

Waiting for a delivery from China at the moment so I will have a close look at everything. I did manage to assemble the Zombieverter kit, somehow, and I do have 10, IC11 coming.

The main worry is more about testing and not further damaging the board.

These are my thoughts so far,

The burned track from C29 to IC11 is 12v+, this is converted to 5V + by IC11, C20, C22 and D1, this 5v is then smoothed through L3 and goes on to power the 5V side of the board. The 12v side is split at the positive of C29 and powers the rest of the 12v needs of the board.

If IC11 was removed from the board, no tracks are shorted and the ECU was powered with 12v normal input and 5v applied to the track between D1 and L3 with 12v - and 5v - connected together should the board should come to life?

Your answer to the the above will probably determine my capabilities to repair the board or let you do it.

Not an expert but reasonably handy with soldering iron and hot air. I'd probably start by removing the IC, and just probing for shorts on the 12v, 5v and gnd like you say. Maybe then try connect with STLink or see if the serial connection is working. If there's any signs of life proceed to replace IC11 and repair the track. Someone with more expertise might have more ideas.

Damien, great to see the Zombieverter is lurching ahead! We have our GS450H vehicle which has been running around for a few months, on fairly old code, with no real problems.

But I want to update it now, the main things we are missing are:
* Working regen
* Smooth current limiting
* Settable throttle response curve

I also need to add some CANBUS messaging to work with other components on the vehicle. Firstly accepting a current limit from the BMS.

My question: Is the current code available and build-able? I know it wasn't for a spell which is why we held off and worked on other stuff. I'll resume adding to the wiki!

Thank you.

I think I have figured out just about everything before I jump into buying the Zom VCU board for the Nissan Leaf Gen 2 stack. Really it was just the ancillaries, like water pump and vacuum pump. I think that is figured out. I know there is probably some work being done for read only display or to connect it to donor vehicle gauges, such as using the pot 1 & 2, DAC, PWM pins. It appears the Zom VCU has a lot of very useful data that can be displayed in a read-only format using an Arduino display screen. If that is possible, then that would be the cats meow! :)
