Moodz' Awesome Gold Pulse Induction Version 3 - MAGPI V3 Project

[Dean Sarelius]

how about 1.5 amp peak to peak bipolar with 1.2 microsecond risetimes and 650 volt flybacks ?? ... for starters.

Great result Moodz.

Dean, if you have trouble with the AliExpress parts drop me your postal address on PM and I'll send you one.
We will need most of what we have for our prototyping but happy to help out for your proto board.

Cheers

Hi Md,
Thats is really appreciated and will definitely take you up on the offer if the Alliexpress chips turn into duds.
Cheers

Hi Dean,
You are correct, no stock. I last looked 3 days ago and there were 650 in stock.
Are you in Au?

MAGPI V4 - Bipolar Nfet ?

Here is the latest firmware for the V3 MAGPI. Version 1.3

Fixed motorboating background noise in audio.

Oversampled ADC for smoother target operation.

This is pretty much the final version .... started work on the V4 MAGPI which will be quite a bit different

Hi Md,
I double checked the TI website both the INA125U and the UA but cant find any stock in the SOIC package..?

Dean,

TI have them in stock, look again for different options, eg cut tape, reel , rail etc and also note the min order Qty.

The board looks very nice ...

Are you including a charger circuit for the lithiums?

moodz.

Hi Moodz,
I have an RC battery pack charger which can charge 2 battery packs at a time.
I wanted to minimise as much as possible any external connections that might allow salt or moisture into the case.
Both the encoder and the coil connector will be exposed to the elements and I have added a low cost Bluetooth audio transmitter so no need for plugging in headphones.

Looks like TI are out of stock also..?

Thanks Moodz,
Ended up buying them from AlliExpress fingers crossed there ok.
The board is mainly surface mount so needed the SOIC package unfortunately.
By the way here is a picture of the board in the case Altronics H0325.
I will prefer to assemble and iron out any issues before releasing all the docs on a new MAGPI V3.1 SMD thread.

The UA part is surface mount ...

One of the reasons I made the V3 a through hole board is the semiconductor shortage after covid.

Mouser have 2933 INA125P and 1034 LM6171 both DIP through hole packages in stock .... Plenty.
