During the Hackjam of the 30th of November 2021 we had an informative conversation about bitcoin. Thanks for Irivan for his resumé of the talk he shared on our IRC channel on libera.chat. Here is a copy:

2. It solved issue of printing money crazily by Government e.g. Vietnam
3. It could replace the currency that we hold if…

Our Business Facebook page got compromised. We tried to get it back, but Facebook has a system in place for you to get back your personal Page, and got NOTHING for getting back your Business Page. We did provide them with a lot of information such as owning the domain name, address proof, pictures, but no, it is not enough; in short Facebook does not care about the Business Pages – who care about the right owner as long as there are advertisement on the page!

I would suggest you to do the…

Today I installed the Air Quality sensor at the Lab. You may have noticed the widget on the right side of the page showing you the important values for Air Quality.
It is constructed around a D1-mini (ESP8266) and connected to an SDS011 and a BME280. It measures the following values:

• Particulate matter PM10

This evening we did not see a lot of members as a few of them are traveling to the Chaos Communication Congress or going on holidays for the Christmas / New year period.

This evening we had the visit of a few visitors, 4 to be exact, coming from the USA. Most of them new to Hong Kong or even Asia in general. We hope to see them again after the festivities.

One of them, Jeff to whom I talk with for some time is interested in golf, and is having his own design golf putter been CNCed in…

On this Saturday the 21st of December 2019, we will organise an afternoon for grown-up and kids to learn about the use of a laser cutter machine and create decorations for Christmas.

Painting will be involved as the laser cutter will only cut the pieces of wood. We will use Inkscape as the software to create the decoration or modify existing ones. We have collected a few ~20 decorations from the internet for the little ones to choose from. Teenagers and grown-up can create their own design.

Please find below the list of the workshops and event provided by the members of Dim Sum Labs in the coming weeks.
