I didn't succeed yet with making one, but that is not because it is extremely difficult - I just happen to live where access to such stuff isn't straightforward. That said, if you have access to the materials, you can start with sre's blog [0]. Additionally, chapter 3 of his thesis [1] has quite verbose description of everything that is needed, as well as a diagram (Figure 3.3) clearly showing the location of the required pins. We can also help you with any further information you may need.
