Frex, the 31 Junary, 2016.


Hello all,

I opened here a new blog page to replace the dedicated wiki page previously
made for this group buy list.
The DIYaudio wiki is unavailable for weeks now and that will take some time
to be re-opened. So for this reason i move the group buy here on this new blog.
I will probably also take advantage of this new blog to share many others things.

Until now, 12 pre-order are done on 25 required. We will wait end of February,
and then if we stay less than 25, i will make a new price estimation for a lower batch.

This is the pre-inscription list for a group buy of the project named EPSUX3V2.

A short video presentation of the PSU at work is available HERE.

The main thread of this project is HERE.
You can post on this thread for any technical question.

The group buy is about only these parts :

I will only accept Paypal payments. The price include all fees and shipping using a priority letter.

The price list above is only available if the group buy reach 25 orders.
Below this, i reserve the right to cancel the group buy.

You need also to purchase all electronics part and enclosure to fully build the project.
The total cost of other parts is 360 (from Mouser, price from 11-12-2015).

So, the total project price is about 500 .

The project include a Altera CPLD (5M1270) with the embedded software
of the PSU. This parts need to be programmed,
and to do that you simply need an USB Blaster from Altera (~15 on Ebay).

If many DIYers are interested about, i will also offer to provide the main
PSU board with the CPLD soldered and programmed (price has to be defined).

I will complete this wiki soon and add some informations
as projects progress.

You can download at bottom of this page some project files as :

* Full schematics of each board.
* Preview manual of the PSU with detailed operation and specifications.
* Full bill of material.

This is a pre-subscribe page, for order on the first quarter of 2016.
