I had a busy week. I have frozen the board design and sent out two PCB designs on Friday.
Both boards have the same functionality, but one of them is pushed to the smallest limit in terms of size (15.2mm x 23.4mm, see the left side of the photo). It will have to be seen if this board can be manufactured and assembled automatically with components. In case not, I have the second PCB design which is a little bigger (17.7mm x 23.4mm, see the right side of the photo) and which should not have any problems for fully automatic manufacturing and assembly.
I will be spending the next couple of weeks on the mechanical design of the package. This package will be based on the larger board. The two PCBs have been laid out in a smart way such that both will fit in the same larger package.
If it turns out that the smaller board can be assembled automatically (or if hand assembly of one or two components is not a problem), then the mechanical package can be shrunk in size by just changing one single dimension of the package! That's why it took a little while to come up with the current frozen board design.
You can also see that I have redesigned the website slightly and re-arranged some things: posts in the center, polls and the blog archive in the left side bar, and my human rights related links in the right side bar.
Upon request, I have also added a donation button on the left top for anyone who wants to donate. In addition, I have added some Adsense ad-links throughout the page. I have noticed that they are quite on the topic of the blog and they will also bring in a little bit of revenue when people click on them.
I am glad I was able to get this final board design out the door before the end of May :)
