is there anyone on here that would be able to lay out the pcb for me, i intend to use the iron on stickers for the pbc or use a light box and accitate.

and then develop it in a tray and drill manually.

single sided pcb would be great.

thanks in advance

hi,
It would help if you posted the circuit diagram.

Hi Cobra1,

I would like to help you. If you can't download Eagle I would create a scaled pdf file of the PCB layout.

However I need a pretty precise part describtion, e.g. what type of LC-diplay and which brand and type of transformer you want to use.

I also assume you don't want to mount the temperature sensor on the PCB but use a three pin wafer (similar to fan connectors on mainboards) to have the temperature sensor where you want to measure.

Here is your PCB design.

Board dimensions are 84.4550X65.4050mm

How long did it take you to create that design Boncuk? That would take me a while, but I guess you get pretty quick with practice. I've only tried designing one PCB and it was a spectacular failure, I asked someone to check it for me and the advice was basically to burn it to ashes.

I'm pretty new to electronics though so I'm going to try again with a much simpler PCB design; I have a very simple schematic for a dual battery / wall-wart power supply for a device which I plan to make a PCB for as soon as I can get my hands on some etchant.

Hi bryan,

not quite. It has one wire jump requiring two vias.

The first design took me two hours including the creation of a package for the transformer.

After having designed PCB layouts for many years you have got routine to place components intuitively seeing possible collisions of traces already by looking at the ratsnest.

As for your spectacular failure I recommend to name (almost) every net when creating the schematic. Print a net list and compare with the intended schematic. There might be unconnected nets to one pin which the ERC won't catch if it is not an input pin. A missing connection can easily happen when switching grid sizes, e.g. from 0.5 to 0.125 inches. You won't discover the missing connection unless you use the "show" function which should highlight two (or more) connected pins.

I'm pretty new to electronics though so I'm going to try again with a much simpler PCB design; I have a very simple schematic for a dual battery / wall-wart power supply for a device which I plan to make a PCB for as soon as I can get my hands on some etchant.

Email me your project including a parts list and I will suggest a neat and error free PCB layout for you.

Very cool, Boncuk.
