Hi, My project is a small one and easy one. Even though hackaday covered v1 and v3 and got attention but i don't know why it did not covered v3 yet. V3 is the finest among other two and more easy to build. I hope hackaday will cover it in their blogs and let people know about it.
An update on headers, use this headers, 2.54mm pitch x 5mm height female headers instead of old size one.
i can't find that header in the amazon or aliexpress. fond this but they are smd part. if you find the part in through hole then let me know here.( I got mine from local shop)
