I've released manual how to program ESP8266-12E via FTDI232. But it is in Russian=)

Re: HOWTO: Flashing ESP8266

Long time no see :) Yesterday I've flashed ESP8266-12E using nothing more than FTDI232(cheap USB-TTL, yet has got everything needed onboard), two 10k resistors and one 100MkF capacitor. No additional power supplies. I don't know why people say it need strong power supply. There are a lot of manuals ...

Re: Something on the wheels.

Re: Toyota MGR Rear Traction Transaxle

Interestin observation: I've connected my second MGR to inverter without changing any parameter and it spins :) It jitters but doesn't run away. So that means for MGR you can start syncofs tuning from 22000 and just tune it a little for motor to run smoothly. Video is in Russian, but there is nothin...

Re: Toyota MGR Rear Traction Transaxle

What is the PCD of the BMW flange? It's 80,1mm. Unfortunately for now I haven't got my own lathe. Flange I've designed was pretty similar to yours. Lathe operator said it would be expensive one. To cut MGR flange and weld BMW one to it would be cheaper, yet the most cheap way was to buy two drive s...

Re: Toyota MGR Rear Traction Transaxle

I was trying to design an adapter plate wich could be bolted to MGR output flange on one end and to BMW CV housing on the other end. Almost immidietly realised that it is impossible, or adapter plate must be thic and over complicated. So I see two ways: cut MGR flange and weld BMW flange to it. Not ...

I believe Johu himself explained somewhere in Prius Gen2 Inverter thread that output current is more then dc input current. Why is there a massive capacitor hooked up to Inverter in a first place :)

Re: Something on the wheels.

Little update: My MGR, powered by Gen3 inverter and v1c board now spins good in both directions. I've tried to design adapter plates to connect unmodified BMW driveschafts directly to MGR's outputs, but for this to happen, they need to be 10cm in length, which is unacceptable. So i'll go the same wa...

Re: The Blue Yacht : E39 + Lexus MGR

So I found a potential source of connectors for the MGR. I happened to have 3 Gen 2 prius battery to inverter plugs. Massaged off the plastic with a mallet and got 3 nice large connectors that fit the MGR terminals perfectly. Wouldn't be surprised if they were the same part. I've tried to just pull...

Re: Mk I Golf cabriolet / Prius Gen 3

About that resolver connection: If, after syncofs tuning, your motor will run good in one direction but run away in other, try to swap ground and positive wires of sine or cosine detectors MSNG<>MSN, MCSG<>MCS. Damien helped me with this hint, when I've stuck with FOC tuning.

Cheap, plentiful and designed for continuous automotive use.
Never thought about it. Great idea. Opel tigra or ford fiesta has got electric pumps. Need to check prices.
