Voltlog #40 – InTheMail

Once again too many mail items to fit into a single video, so we have a two parts upload. In the first video I only had time to show two items the SONOFF from ITead and the SP mini from Broadlink but that is including teardowns and discussions on the internals.  Surprisingly the SP mini doesn’t use the ESP8266 as expected but instead it uses the MT7681 from MediaTek.

Voltlog #37 – InTheMail

Hi and welcome to a new InTheMail, this time we have allot of items to look at and some of them were ordered 2 or even 3 months ago but due to the postal service madness that happens every year during holidays they arrived a bit late.

The video is split across two parts to avoid making it too long so make sure you watch both parts.

Voltlog #31 – InTheMail

Usually when I order stuff from China mainland to Romania it takes about 3-4 weeks to arrive while stuff from Hong Kong takes about 5 weeks to arrive. However every year orders placed starting from about 15th of November up to 31st of December take very long to arrive sometimes even arriving after 8-9 weeks. So right now about a third of my orders are late or missing because there is also a good chance they will never arrive once they go past the 8 weeks mark.

A list with links for all the items shown is in the video description so do check them out.
