I wrote a small PHP script to backup a specific MySQL database, compress the dump in a password-protected zip-file and upload it to dropbox.

To have a simple shield for the Raspberry Pi’s I created a Breakout for the GPIO headers. The Breakout is usable for alle generations of the Raspberry Pi by cutting along the marked line.

For different purposes I created a Breakout for the Particle Photon which can be used for mounting a Photon with and without headers. Both footprints are connected in parallel so a project can start with a Photon with headers and later use a soldered Photon without headers.

While reading about dangerous USB power supplies I decided to investigate the safety of the power supplies used by my wordclocks. I stumbled across the USB power supply tests of HJK and discovered a similiar power supply to the one I am currently using (ETA-U90EWE) which is according to the test result not that secure.
HJK saw a passed safety test for the Flypower PS10A050K2000EU so I decided to buy these. Unfortunately the reseller sent me the follow-up product: the Flypower PS10E050K2000EU. To make sure the new model also passed a safety test I contacted Flypower and they showed me the CE and GS safety test results. So I can confirm this follow-up model is also secure to operate.
They also showed me the CE and GS safety results for the next generation Flypower PS10J which should be also secure.I disassembled the power supplies to make sure the short voltage distance is big enough. You can see the big distance on the Flypower PS10E (left) and a very bad distance on the ETA-U90EWE (right) on the images below.
