Mar 2026【隨筆】Clone a Meta Ray-ban Display glasses application|藍芽 L2CAP CoC 極致低延遲架構優化:實現 720p 智慧眼鏡流暢串流 👓(LIVE DEMO)

最近在做一些實驗性質的東西,記得去年短暫玩過 2023 年底上市的第二代 Ray-Ban Meta 智能眼鏡,雖然它主要還是依賴智慧型手機作為算力中心,但我們對它所使用的串流技術很感興趣,因為聽說他們是用藍芽做串流。 去年曾經有同事隨口問我:「我們的眼鏡做到跟他們一樣你覺得有可能嗎?」,因為我知道我們的硬體規格跟人家的相比並非等號,加上當時有其他事情在搞,所以隨口開玩笑回說:“可是聽說 Meta 有200個人在搞那個眼鏡捏(雖然不知道他們負責搞應用的有幾人),啊我如果一個人可以幹贏他們200人,那我還在這幹嘛???(笑)” 也記得更久以前,當我們還在研究那個眼鏡時,常聽到像是:『 他們不知道用了什麼黑科技 』,這類沒有建設性、不應該從 RD 嘴裡說出來的話,而我也是不以為然。坦白講,以前每次只要聽到某SW嘴砲經理(暫且以H君稱之),沒事就把『 黑科技 』三個字掛在嘴上,當做無知的遮羞布,我就會感到倒胃口!同樣身為RD,我只覺得  Shame on you!(打嘴炮、作秀搶風頭、噁心帶風向、搞政治操作、把別人做事的成果搶去幫自己抬轎、有鍋直接推給下屬扛、散佈同事私生活謠言,還有職場霸凌,這些你他媽都頂級專業戶,除此之外沒啥洨用了!) 一件理論上可以做到的事情,外行人的認知被信息差,不懂加上沒實作能力去驗證,就什麼都變成黑科技了(多黑?比巴西黑鮑魚還黑嗎?)。反重力技術說不定也非啥黑科技,只是政府不讓你普通老百姓了解罷了。 Ray-ban Meta 的黑科技,講白了就是人家拉個百人團隊在搞那支眼鏡,然後把軟體技能和硬體規格點滿,再加上極致優化後的成果罷了! 當時知道 Ray-Ban Meta 的智慧眼鏡有塞入一個強大的 WiFi 6 晶片在裡面,一開始我猜測會不會有可能是透過 WiFi P2P 或 WiFi SoftAP 的方式去做串流(確實 Meta 的智能眼鏡,在同步媒體時,會強制要求開啟手機的 WiFi 開關,所以媒體同步應該是靠 WiFi 通道做的),而去年初我也快速做了一個WiFi Direct 架構來做 POC,確實傳輸效率非常快,幾百 MB 的大檔幾乎秒級傳完,從眼鏡端將媒體串流到手機端更是不用說的順暢,而且當時我們的媒體串流還是以未經編碼的方式傳透過 Socket 直接傳輸的(這表示傳輸時所需的頻寬會更大,功耗據說也較大)。 後來因為 ...

2017, Oct 1st ~ 4th【泰北♡清萊】Travel to Chiang Rai, Northern Thailand (2nd visit to Thailand)

Chiang Rai Province is located in the northernmost of Thailand. It is a mountainous region with rivers and jungles, so there is a lot of beautiful nature surrounding the area.
The north of Chiang Rai borders Myanmar, the south borders Phayao Province, the east borders Laos, and the west borders Chiang Mai Province.
The cool season is the perfect time to visit Chiang Rai because the weather will be incredible and you will get a chance to enjoy beautiful views from the mountain tops.












Phu Sang National Park is located 90 kilometers from Phayao Province. Take the Phayao–DokKhamtai–Chun –Chiang Kham –Thoeng Route, 6 kilometers from Amphoe Chiang Kham. The National Park provides accommodation, camping areas, as well as convenience stores for tourists.











Phu Chi Fa Forest Park is one of the most famous destinations uphill in Chiang Rai, especially during winter time, when visitors try to reach its cliff that offers spectacular views of the valley and sea of mist at sunrise.
The peak stands at an elevation of 1,628 meters above sea level and offers amazing views of the landscape below.  From the peak, you will expect to experience the views over Mekong River and the spectacular mountain scenery.














































The village of Pha Tang has the lodgings, from camping tents, hotel rooms to bungalows. The cost is about 200 baht per tent to 500-800 baht per bungalow. However, if you avoid major Thai holidays and weekends, there is plenty of supply for lodging.










Doi Pha Tang far from Chiang Rai town about 160 kilometers, and is about 25 kilometers north from the well-known Chiang Rai’s tourist destination – Phu Chi Fah
In Doi Pha Tang there is a very beautiful hill on the border between Thailand and Laos located in Wiang Kaen district of Chiang Rai.
The best time to go hiking in Doi Pha Tang is during December and January. The Sakura trees are in full bloom at the end of each year and pathways covered in pink like floss makes it an ethereal experience.
A short trek in nearby hills finds a mountain gap which overlooks the lower planes of the North. Views of the Mekong river and on the opposite the lands of Laos. The diversity in these areas partly due to the location near the Golden Triangle where four countries come together; Thailand, Laos, Burma and China (Yunnan). 
While the viewpoint is what drives visitors to Doi Pha Tang it is more popular in early months (January to March) when the area blooms with pink Bauhinia flowers and Thai Sakura.




















The Mekong River is a river in the south-eastern part of the continent of Asia. It flows through the countries of China, Burma, Thailand, Laos, Cambodia, and finally Vietnam. The Mekong begins in the Lasagongma Spring which is in the plateaus of Tibet, disputed part of China, and flows about 2,703 miles (4,350 km) south-east to the South China Sea.







































The Baan Dam Museum (also known as the Chiang Rai Black Temple or Black House Museum) is a museum and gallery that was home to the renowned Thai artist, Thawan Duchanee.





















Wat Rong Khun, also known as the White Temple, is the most popular attraction in northern Thailandand is located about 30 minutes south of the historic city of Chiang Rai. This temple was designed and built by artist Chaloemchai Khositphiphat in 1998 and building still continues today.



The Chiang Rai Night Bazaar is a vibrant market that brings Chiang Rai to life at dusk. It is similar to Chiang Mai’s night market, albeit on a smaller scale.
The Night Bazaar is held nightly between 6pm-midnight and sells a huge range of hand crafted items, cloting as well as authentic Thai foods.
