I eventually learned that they are very flimsy technology, easily breaking or failing in various ways.</p> <p style="margin-bottom: 0px;">This pair simply stopped working one day. I just found it and asked my wife to fix it - she understands electronics and I don't at all. I don't know what exactly she did, but they work now. Another set couldn't be fixed and had to be trashed, but one got rescued!</p><p>Photo by <a href="https://www.23hq.com/Gwenlyn/">Gwenlyn</a></p> https://www.23hq.com/Gwenlyn/photo/5276157 Mon, 11 Jan 2010 05:37:01 GMT https://www.23hq.com/frickel/photo/5171763 <p><a href="https://www.23hq.com/frickel/photo/5171763"><img src="https://www.23hq.com/4937363/5171763_a91f7d7c44afae67ec8102b6f92cbca0_standard.jpg" width="460" height="375" class="23-standard"/></a></p><p>A re-design of our USB Developer Board with a new name - OpenFrix v0.1.</p><p>Photo by <a href="https://www.23hq.com/frickel/">frickel</a></p> https://www.23hq.com/frickel/photo/5171763 Fri, 11 Dec 2009 00:46:04 GMT https://www.23hq.com/frickel/photo/4961217 <p><a href="https://www.23hq.com/frickel/photo/4961217"><img src="https://www.23hq.com/4937310/4961217_aad61bb9a6f90de85382fbcf6b859bad_standard.jpg" width="460" height="336" class="23-standard"/></a></p><p>Second revision (with DC-Jack) of the Matrix8W PCB (and also my first PCB).
