We are complete, 5 sets have been given, we just have to decide how to do it with transport and payment.

Perfect, so it looks as follows:

mweymarn 1 set
eliocor 1 set
parasole 1 set
Edison 2 sets

I will move to private for the rest of the details, after all this is a technical thread :)

If anyone in Europe will start a new order, I'd be interested to take a PCB Set. Pls PM

PCBs are made to order, they are not ready in a warehouse so that they can be left over, therefore the minimum order is 5 pcs.

Are all 5 spoken for ? If not, I would like one set. USA also.

Hi,
I am interested in the PCB set. Do you still have one slot available on this?
I just learned about this project yesterday.
Thanks!

Yes, But.....

I screwed up and only ordered the back panel (very new to this, who the Hell was Gerber?) (actually I am curious).  I will talk with PCB and order the complete package (sans back panel) on Monday.

I KNEW it was too easy! :-DD

Gerber files are the files used by the PCB house to build the boards. They contain all the information needed for the machines to build the boards (vias, pads, sizing, etc...)

I got the order straightened out. The other 3 boards are on the way! (I have the rear panel).

@Watchmaker I am tentatively interested in a set of boards as well. Did you order the main and front PCB's with the SMD parts soldered?

OK.  the Boards are in.

Let me know if you want a set.  With shipping to me it will be $55 USD per set plus shipping to you.  Overseas is not an issue for me.  I have 4 sets, one I think is spoken for.

Hi everyone, I had long COVID and huge health problems... sorry! As a matter of fact, it's been some time to this forum.
600 euro for 10 sets of parts?? I was under the impression it was the price for one. If that is NOT he case, 60E + 55 for the boards is a bargain.
I'm still interested...

Hi, I'm interested in a set of boards, shipping to the UK if they're available.

Please let me know.

The precursor of the modern embedded system instruments:



The instrument system/software is entirely housed inside of the FPGA of the DE10-Nano, no additional system/PC/computer is necessary to operate the instruments but multiple PC's can connect to the FPGA board instrument server as clients to start the instrument software and get data. Additional ADC/DAC and signal conditioning electronics connected to the DE10-Nano were required.

Hey Dewey,

I'm in the US and would be interested in a board set if you still have any?

Thank you, Dewey, for the board set. Much appreciated.


For others that come along: expect to spend around $600 USD (2024) on the total project.

I have shopped, and shopped, and shopped for the required parts.
Ultimately I ended up with $95 in parts at Newark and most of the rest at Digikey. This maddening effort saved me around $85 USD in the end.


Absolutely do not buy the 6 banana jacks at Digikey @ $6/ea. Newark has them at $2/pc.
Even with the separate shipping you come out way ahead!

Newark also has some of the expensive switches/etc for a fair amount less:


SP3T  switch M2024SS1W03:
Newark has 5 in stock with more expected Dec 2024. Digikey has zero and lists it as obsolete

M2024SS1W03-BA is an equivalent, with just a plastic/rubber bat hat as the only difference.
It is also discontinued; As of July 20, 2024 Digikey has 13 left in stock. Newark lists it as NLA.

This SP3T has been surprisingly difficult to match.


Rotary switch MRA112 is obsolete, limited stock..Digikey has 120 as of July 20, 2024.
MRAN112 seems to be a new replacement. I cannot confirm.

Newark has the rotary switch 51P22-01-1-16N for about $8 or so less than everybody else

Newark had the better prices on 1 or 2 of the transformers.

There were a few others that stood out, but you get the idea.


As for the special 5 row test sockets --- good luck. The Aliexpress link in the BOM seems to be the only option

EDIT to add:

I can't stress this enough, but don't waste your money, patience, or time on P1 & P2 on the front panel. These are an abortion that will not accept anything put the stiffest of wire with far too much effort.
Just avoid the expense and headache and solder your wires direct to the board. I wish I had.
Found on the Front panel BOM:
Amphenol NQ0321100000G, Digikey 609-5214-1-ND



ALL OF THIS and more has been fixed in the BOMs, with more that has been fixed and more coming.
Front board BOM has some gotchas with the Digikey part numbers
Digi-reel part numbers instead of cut tape, which adds $7 to the cost of each

line 53:
$7.10 vs $0.10
2019-RK73H2ATTD2051FDKR-ND  ----> 2019-RK73H2ATTD2051FCT-ND

line 59:
$7.10 vs $0.10
2019-RK73H2ATTD2493FDKR-ND  ----> 2019-RK73H2ATTD2493FCT-ND

line 61:
$7.93 vs $0.93
497-14376-6-ND ----> 497-14376-1-ND

I would also like a set of boards and panels if this helps make up the numbers. I'm in the UK. Thank you.

NB JLCPCB are quoting £49 GBP including delivery to the UK for a set of front panels, front and main PCBs, or £59 if you want the rear panel as well. £20 of this is shipping, so five sets of boards work out at only £30 or £38 with the rear panel. You could 'panel' the boards into a single PCB to save a bit more, but run the risk of errors when merging the Gerber files. Give the total project cost, buying your own set of boards might make sense.

Interesting, they charged me $50 for shipping alone.  And then $200 for the 5 sets of boards.  Price drop?  Currency exchange?
