quem colocou este projeto aqui não quer que ninguém monte pois não tem o HEX do PIC, este circuito é uma fria montar, deveria haver um pouco mais de sensibilidade de um autor desses, o arquivo comprimido também não tem o HEX, UMA PENA !!!

Very cool this project.
Where I can download files – sch, pcb and PIC firmware – for this project?

Heya i’m for the first time here. I came across this board and I in finding It really helpful & it helped me out a lot.
I am hoping to present one thing back and aid others such as you helped me.

Can anyone help? I have built the circuit board and populated as per the list above. I had a specialist transformer made which includes the 24V supply and the 6.3 V supply rail.
When populated with the ICs it does not output any voltage but with IC3 removed the output voltage is the rail voltage of about 34V. IC3 (the op-amp) seems to taking the current from the transistor. Pin voltage on IC3 is +30V (pin4)and -1.28V(Pin11).
I cannot understand how to get round this.
Suggestions please. Has anyone else had the problem

I second what Denis said (except the profanity). I cannot download the plans due to adware interference. Please clean up your site so I can get this download and begin my project.

Thanks!

You cannot download from link provided, goes to adware shit, Shows this site in a poor light.
please give valid download link

Hi,

Would I be right in thinking that the 6.3V transformer is not critical? Looking at the 337 datasheet for calculating output, input voltage does not seem to be critical.
I want o use a 9V or 12v supply (otherwise I will need to pay an import charge to Farnell to bring a 6.3 V transformer into the UK)

Thanks, think this is a great project, which I’ve been looking for sometime. How you guys work it out is quite amazing.

sir what’s the meaning of JP1 and JP2…do i need to short it?..is it possible to replace the IC1 op amp with LM324. i already build the circuit, but the LCD only light on in few seconds and light off again..how can i troubleshoot it..

and….where should we get the output?

sir how to test if the PIC microcontroller really works, we already burn the program…
