Hi,

So, as you may know, I have "some" PCBs for Maarten, PA0MHE's plugin for the Wavelab transverter boards. I have successfully stuffed some boards on my pick and place machine, including the vast majority of the Rs and Cs, the "hard" silicon and soldered it in my PCB oven. I'll add the 2 large regulator devices , the (U32, U33), the ADM7151ARDZ (U52) and the 2.45GHz filter not shown in the photo. U6 (not shown in photo) will also be added.

This leaves some surface mount inductors, hand soldered connectors etc. It took Maarten 2 hours I think to finish off, which was considerably shorter than mounting all the Rs and Cs by hand!  To date, I have soldered up several boards for Maarten and we have had zero problems with the placement and soldering of the synth chips etc, no solder bridges under the chips yet ... but please bear in mind, whilst every effort has been made to get it "right", these are not tested, but they are inspected to the best of my ability.

The cost of the boards with the components as per the attached PDFs is £100, I appreciate this a non-trivial amount, but this is "at cost" for the silicon plus a small amount (£8.50) to cover the passives, solder, cost of stencils for the paste etc  See spreadsheet.

I've had more requests for boards than I ordered part sets, so I will place 1 last order for parts this week from Mouser, lets say Wednesday evening. I have 5 made up here, I will just order the extra components, run the remaining boards and then take the components off the machine.

My list of people who expressed interest is:

Me x2

M0GHZ

G3WIE Chris
G4NNS Brian (via WIE)

G4GXL (2, to be confirmed)

Peter VK3PF

G8IKP John

AA8IL  Mike

SP5MS Peter

Could those listed please just email me to confirm or deny they still want them, (absolutely no problem if you have changed your mind, as I have more requests than sets of components) and I'll order the extra components and close this off, so I can get the machine set up for the next project ...

I suggest Recorded Delivery post, given the value, I'll find out how much that is ... or I can send just 1st class for free in the UK.  Overseas post will be at cost.

Any more takers? The component order is going in tonight ... if your name is not on the list and you think it should be ... or shouldn't be, now is the time to shout up.

Hi Robin

While I don’t see many people in the north on the list there does appear to be quite an interest. If not too late could I get 2 assembled ones please - at least I can work myself until the access picks up.

If too late not a problem

Thanks

Hi Robin,

I thought I had put my request in before.

No matter, please add me for 2 boards.

thanks

I have a Wavelab transverter that I haven't done anything with yet.

Am I too late for a board?

Hi Robin
If there are still any extra components spare please could I have a board?
