Pickini V4 SMD File

Thank you for your help

SMD layout. Ready to print.

@bang80:

my Pickiny V4 buil with semi kit of Bernard is very good.

Glad you liked it. The purpose of the kit was to lower the threshold of using a small yet powerful microcontroller.

Now, that you have the SMD layout - thanks to bernte_one, Arionas, dbanner, .., please be aware that you will have to program the SMD controller yourself.
The programmed chip that I offer separately or in the semi-kit is the through-hole version.

Success !,
- Bernard

Hi,
Thank you for the PDF SMD version. I have the program, a program card , PIC pgm software and SMD version of PIC. So I will try to build that with my hot gun and solder paste.
Have a nice day !

IC Fuse setup ???

I am close to starting this project I understand that 10K is ok for the sensitivity pot, but where is that listed on parts list ?

If I connect just 5v +and - batt to the chip will it produce any pulses just for testing programming ?

[BC547]

The sensitivity potmeter between 5v and Gnd can be 4k7 or 10K.
It is not listed in the parts list.
The parts list is just a copy of the BOM generated by Eagle - and since the potmeter is not on the PCB, it's not on the parts list.
Neither is the audio jack, on/off switch, pinpoint pushbutton, ... anything that is connected via wires to the PCB.

If you power the microcontroller only - 5V only, it should produce the welcome sound on the audio output.
And after a while, a low error sound because the coil flyback is not detected ( coil not connected ).
You should also have a 100 microsecond pulse every 2 ms on pin 5 of the controller - this goes to the IRF gate after level conversion to 12V.

Thanks reply, will try and test the chip tomorrow

The chip seems to test ok thanks.

Is this a double sided PCB with ground plane? What type switching fet is used ?

[BC547]

Guzzi,

you can find all construction details here : http://users.telenet.be/willaert/MD/.../V4/intro.html

The PCB and schematic page: http://users.telenet.be/willaert/MD/...ectronics.html
.
It is a single sided PCB with a ground plane and the FET is IRF740.

You can make it easy for yourself by buying the semi-kit with the PCB and all semi conductors including the programmed PIC controller:

Fantastic project Bernard, along with your patience in helping folks out with the build. I read through much of the thread and the info on the project site and have a quick question. How does the temporal method handle EFE at the end of the swing?

Hi Bernard, in eagle what are the 2 and 3 terminal blocks parts called ? thanks
