Saike 858D++ - First Block Diagram

After a short break, here is the first part about the redesign of the Saike 858D rework station (Overview).

Let’s talk about a rough block diagram for the new design.

Saike 858D Rework Station - Measurements

The next part in the series about reverse engineering the Saike 858D rework station (Overview) brings a few measurements, I did in my device. It presents me with the problem, that I am not sure anymore if I want to keep the transformer, currently used in the station.

Reverse Engineering the Saike 858D Rework Station

Quite some time ago I bought an SMD Rework Station at AliExpress. The station I ordered was a Saike 858D, which is one of the numerous versions of the 858D line of rework stations. The “original” model is probably the Atten 858D+ which Dave Jones from the EEVBlog also did a tool review on. My station was really cheap and I am, in general, glad that I have it.

However, as usual with cheap equipment, there is also a bit room for improvement. That is what I am trying to do here.

Measuring Air Quality - Adding a Gas Sensor

At the time, there is quite some discussion regarding air quality and pollution going on in germany. Some cities, like Stuttgart, have to deal with high levels of fine particle emissions. That is why some people came up with a simple solution to build a sensor network for air quality. They provide detailed instruction on how to build your own air quality sensor for about 25 Euros. So, if you want to participate, just head over to luftdaten.info

AK Homöopathie - Ein Ende(?)

Die Vorlesungszeit des Wintersemesters ist um und auch das Programm des “Arbeitskreises Homöopathie an der CAU zu Kiel e.V.” ist für dieses Semester beendet.

Erfreulicherweise ist damit aber wohl auch die Zeit des Arbeitskreises an der CAU insgesamt beendet.

Bericht AK Homöopathie - 16. Januar 2018

Am 16. Januar 2018 fand erneut ein Termin der “Ringvorlesung” Homöopathie statt. Leider konnte ich selber nicht an dem Termin teil nehmen, aber das folgende Gedächtnisprotokoll wurde mir von einem Besucher zur Veröffentlichung zur Verfügung gestellt.

34C3 Watchlist

Another year has passed and that means another congress has been visited. This year the congress moved to Messe Leipzig instead of the CCH in Hamburg. I was sceptical about the new location in the beginning.
