I'm not sure with ny lcr...



What frequency should i get when i attach 3mH inductor to Tx J1, just for test.

[Hyena]

I just finish the smd board with concentric coil
Tx 6mh 20cm diameter
Rx 6.5mh 10cm diameter
Cx about 28 turn

When i check the freq from Tx coil i got 13.2khz with air deep about 18cm.
When i reduce the winding to get 14.5khz for Tx and 13.9 for Rx, the deep is very low...
Any sugestion?

Your residual voltage is?

Did you measure caps and inductance? for 22n and 220n with freq 13,2kHz I am getting 7,2mH. Something is wrong...

I've never seen this particular layout before, so be careful. I recommend only using proven layout, as it saves a lot of pain down the road.

The red frame is still 70,8mm but the green copper is about 69mm , i think it will work.
I need to place the GB Pot more to the right and make the filled areas (corners) nicer.

Im not sure about this layout by the way, i found somewhere in the internet its not tested.

Thank You!

[dbanner]

or you could go with bigger enclosure

[dbanner]

even smaller

[BKY1337]

Looks good. I could use a tape to prevent a connection between the enclosure and the rails.
But it is still too big, i measure 70,8 mm.

My enclosure is 70 x 100mm and i need a little bit space for speaker and pots.

Sorry, and thanks!

[dbanner]

Look at this, it will fit

[BKY1337]

Thank You , im not sure with the left side , the smd capacitors because the pcb will be in a groove and my enclosure is an aluminium one. I fear that there will be a connection between the 12v rail and the capacitors.

I think its still a little bit too big , but thanks.

[QUOTE=BKY1337;238931]Can someone make this layout a little bit smaller?
It needs to be 70mm wide or less. A little bit smaller would be better.
I have 70mm space in my enclosure.

Is this enough?

[BKY1337]

I dont understand what you mean. When i scale it down it will be smaller and the parts wont fit anymore.

[dbanner]

thats easy to do, just load into sprint,go to file/print, you will see scale option. you can use this to reduce or increase size of layout to print for etching.

You have to connect TX coil to get correct power supply voltages. Did you try it with Tx coil connected?

You're right DB! Now its working, Thanks
And i forgot the conection of 4024 gnd, you need to make a link to the nearest gnd supply.
