Turning Raspberry Pi into Shop Display 樹莓批電子餐牌顯示

Shortly after my retirement, I had bought a number of Raspberry Pi Single Board Computer for fun and DIY works. Projects that I had engaged included network based time-lapse camera and multi-nodes Docker Clusters. Later on, as I needed to focus on running my own cafe, all my Pi projects were shelved. In my current setup of the cafe, I do have an electronic display system built on top of the Raspberry Pi. Relaxed and let me share with you my shop display box. 剛退休時買了數片 Raspberry Pi (樹莓批)單板電腦,學習製作一些簡單的 DIY projects。先後做過些網絡縮時攝影機、Docker Cluster。後來因為需要集中精神攪好我的食店,只好暫時放下。 其實在食店內我也有利用 Raspberry Pi 整合了我的電子顯示屏,就在這𥚃和大家分享一下。

Unboxing – Round Three 第三次的開箱

I have written several unboxing posts covering life-style and IT related topics this month. To keep up the momentum, I have just completed another one. 這個五月已經寫了多編不同性質的開箱文,有生活閒情,也有資訊科技;那就不要讓熱情停下來,再來一編吧。

Works had been put on hold and school life suspended. Work-from-home becomes major mode of work for adults and distance learning being adopted for students. My boy has been away from school for nearly four months and has jumped on the video conferencing bandwagon recently.

Getting My Next Mobile Platform

Ever since I have quit my job in late 2017, I don't have any notebook computer with me. This sounds a little bit inconvenient and I have been thinking of getting my next mobile platform for quite a while.

Enabling BLE and ANT+ under macOS

Getting Your Old iMac to Speak ANT+ and BLE

Tired of running your bike training and virtual cycling system on your smartphone, tablet with tiny screens? Constrained by the limited connectivity options and/or processing power of those smart devices?

Apple iMac Mid-2011 RAM and SSD upgrade

Extending My Old iMac’s life 令我的舊iMac回復青春

My first Apple iMac has been running for more than 6 years and is still doing its very best to support my normal day-to-day works. To be honest, 6-year is a very long time for a computer and my iMac starts to show its deficiency - start-up very slowly and unable to handle those resources intensive works like multimedia editing and program development … 不經不覺中,我的第一部Apple iMac桌上電腦已替我工作了六年多。日常工作它仍然升任,不會令你失望,只是歳月留痕,令它慢慢的追不上時代的步伐了,每次起動都需要花上十數分鐘。近來亦多了用它作視頻編輯及程式的開發,更令它吃不消 …
