Afterglow GI - AGGI for short - Bulk order

Good evening,

I was planning to prepare a bulk order through PCBWay for my own usage of about 10 AGGI boards, and @stumblor mentioned that there might be a few interested.

I still need to submit the BOM to PCBWay to get a quote, so I will fill up the cost information when I receive it, however it is very likely price will be below 50 euros (excluding taxes and shipment) - since that's precisely what I paid for a fully assembled 128x32 PIN2DMD board through PCBWay, and AGGI is far simpler in design.

A few notes notes:
- I'm located in France, so shipping will vary depending on where I need to ship afterward
- No cable provided (this is a hell of work), no PCB standoffs/screws, just the board
- No Arduino either, you need to source it yourself.

- This will be a zero profit initiative, only manufacturing/material cost, import taxes (warning, they can be high, in France it's about 20% plus admin, and it's a lottery whether they can go through customs without tax duties), and shipping cost to you.
- I have yet to think about how how to test the boards as I don't have a test fixture, and how to account for defective boards

In the meantime, could anyone interested please PM me. I'll have a hard time tracking the main thread, so please private message only. I will publish on the main thread the names and number of units so you can check you are on the list

Cheers

[EDIT] Current quote for 20 units is at $63 per unit + shipping. I'm expecting the cost to drop by a few dollars as I identified an error in the BOM.
[EDIT2] I checked the BOM, and there is no room for improvement (aside from component negotiation which is probably overkill).
[EDIT3] Just realized I forgot the PCB cost in the cost breakdown, adding it below

Price breakdown (bulk order of 20):
$49 PCB cost, $233 assembly cost, $983 component cost, $58 Paypal fee, shipment to Europe is Free using Fedex-IP (seems there is a temporary promotion on shipping)

So per unit cost: $67 (US dollars, as PCBWay quotes in dollars)

NOTE (to ensure everyone is on the same page):
- This does not include potential tax. There are times where some of my shipments were taxed (add 20% + admin fee), others where it went through without taxes
- This does not include shipping from France to your final location. While it's expected that shipment to Europe will be sub $20, I have no clue about other destinations.
- as you can see I need to make an upfront payment of more than $1200 dollars, so before committing I really need to ensure that people will commit for their unit. I won't charge before shipment to you though.
- I will test a few units at arrival, but I have no way to test them all.
- I don't charge a cent for the work

Please confirm interest, as I have to perform an upfront payment for the whole lot.

Note: you will also need cable and connectors.
Note that some of the connector (the 34 pin pin female header that mounts on the ribbon) are rather expensive, and you need three of them (10 euros a piece), so total cabling will likely be around 40 euros (unless @stumblor can comment and point out if I'm making a mistake)

Current list of interested parties

@stumblor 2 units [Confirmed]
@Andypc 2 units [Confirmed]
@Fifty 2 units [Confirmed]
@MajesticPinball 2 units [Confirmed]
@broomstick 2 units [Confirmed]
@David_Vi 2 units [Confirmed]
@Paul 2 units

I'm up for 2 @Ashram56 will pm you. Thanks a lot for doing this! It's a big effort but makes a huge difference to a machine and will be greatly appreciated. 🤜🤛

I know absolutely nothing about arduino, as long as there's no crazy coding involved put me down for 2 please
 
Just updated the first comment with received names.
Would appreciate country of destination for each as well (I'm located in France)
 
Original post updated with cost breakdown
@Andypc please confirm interest, so far this is the only one missing from the original list

Regards
 
Good morning,

Locking down list
I updated the quote details (I had forgotten the PCB cost)

Will issue order later today

Regards
 
Thanks very much for sorting this out. Appreciate the work! Price is okay to be expected with the smaller runs.

Anyone who needs the double ribbon connector made up hit me up I have the bits to do it.
 
I increased the total number of unit to account for the additionnal demand, so up to 25 units now.

Order has been issued, so no more order now :)

PCBWay is asking for the Centroid file, I must admit I'm confused as I don't recall uploading the Centroid file for my Afterflow order. I'll check with them, but @stumblor would you know how to generate it ? (I must admit that I'm not too proficient with the CAD tool, plus I don't even know what tool was used to create AGGI).

Also, it would be good if you could point to the connector reference you used for the ribbon cable (a Mouser link) for everyone benefit.

Cheers

I assume it's this version you are using @Ashram56 ?

https://github.com/bitfieldlabs/aggi/tree/master/afterglow_gi_nano

If so, I was able to import that into EasyEDA and export a 'pick and place' csv, which I believe is the same as a centroid file (@MadNat would you mind having a look at the attached file and confirm please).

Here is the Centroid (one of 2 - top and bottom were seperate files in one zip file) for the Afterglow boards:

You have many more columns in your setup. There is a help page on PCBWay to give spec of Centroid file they require:
Creating CENTROID PCBWay

Hope that helps.

Mike
 
Thanks mike. I thought the centroid file was less of a bom, and more of a component location thing?
 
Let's take a step back just to be sure:
- Reading through it, @stumblor the file you provided two comments above is the Centroid file for AGGI, right ? Unless I'm mistaken, @stumblor file precisely includes part reference (first column), and component location
- @stumblor, when you ordered your Afterglow at PCBWay , which Centroid file did you use ? I'm using this gerber: https://github.com/bitfieldlabs/afterglow/tree/master/afterglow_nano_smd
- @MadNat, I'm not sure I understand your comment: "one of 2 - top and bottom were seperate files in one zip file", and you seem to imply this Centroid file is for Afterglow, not AGGI ?

Sidenote: who is the designer for Afterglow and AGGI ? Both are really great design, kudo to him/them. Just wondering what it would take to accomodate for Stern as well.

I'm also trying to understand why BOM cost for AGGI is higher than Afterglow by almost a factor of two, out of curiosity (it's actually higher than a PIN2DMD...)
 
I helped Stumblor with the Afterglow project - and created the Centroid files for him. I was giving the Afterglow Centroid file as an example. There were 2 csv centroid files submitted to PCBWay for the Afterglow project - one for the top layer, a second for the bottom layer, we put them both in a zip file. Simply using that project as a guide for packaging up files for your project - before sending to PCBWay.

Not sure about the BOM costs if you share your costing sheet I'd be happy to have a look and see if there are any significant areas of cost difference.

Good luck with your builds.

Mike
 
@MadNat could you share the full ZIP file with both layers for Afterglow ?

I will need to generate the Centroid file as well for AGGI, I'll install EasyEDA
 
Hi @Ashram56

You can use EasyEDA online if you don't care to install, it's great resource. The feature I used was the 'Export Pick and Pack file' which I assume contains the same data as the centroid files that Mike (MadNat) generated, although both sides are represented in one file, unlike Mikes where they were split into two. The file I provided is definitely the one for the AGGI, not the AG.

The AG one is attached here (the one Mike generated). We used the same design as you: https://github.com/bitfieldlabs/afterglow/tree/master/afterglow_nano_smd
