The old Audial DIY stuff is not available anymore.
You can however still find some projects online.
Also, we will make one more run of AYA II 2014 DIY project, starting in the second half of October, so you can use this chance to buy the kit or PCB. For up-to-date information on this item, please visit Audial blog.
For regularly available Audial products, please check this page.
