第一SLA 3D列印電子小提琴就在這裡!很明顯 - 這是驚人的!( The First SLA 3D Printed Electric Violin is Here! It’s Amazing & It’s Clear ! )

Over the past year or so, we have really begun to see musicians and designers utilizing 3D printing technology in order to create unique, custom, and incredibly sounding musical instruments. We’ve seen everything from guitars to cellos, flutes and violins all fabricated on 3D printers of all kinds. Most of these instruments have been created either on FDM/FFF based 3D printers similar to those found on many of our desktops at home, or large industrial level selective laser sintering (SLS)machines. Now, however, one musician, named Laurent Bernadac had taken things up another notch. Laurent Bernadac, you see, has taken it upon himself to create a fully playable electric violin which has been printed using stereolithographic (SLA) technology. This has allowed him to create one of the most astonishing violins you will ever see. [在過去一年左右的時間,我們確實開始看到音樂家利用3D列印技術設計創造獨特的令人難以置信的動聽樂器。我們已經看到了一切各種3D列印機製作之吉他到大提琴,長笛和小提琴。大多數這些文書已經建立或者在相似於我們的許多台式機在家裡,或大型工業級選擇性激光燒結(SLS)的機器發現FDM/ FFF的3D列印機。現在,然而,一個音樂家,一個名為Laurent  Bernadac 採取的事情了另一個缺口。Laurent  Bernadac,你看,已經使用 stereolithographic(SLA)技術印製他自己創建一個完全可玩的電小提琴。這使得他創造一個你永遠不會看到的最令人驚訝的小提琴之一。]

Called the 3D Varius, not only does it play crystal clear music, but its bout (body), neck and the majority of the rest of the instrument is 3D printed in a clear material as well. [ 叫 3D VARIUS,它不僅起到清澈的音樂,但它的 bout(體),頸部和大部分儀器的其餘部分是透明材料3D列印。]

Bernadac’s design is actually based on a Stradivarius violin; a violin which was built by members of the Stradivari family during the 17th and 18th centuries. It is 3D printed in one single piece, which strays quite a bit from traditional violin production, using UV light to cure a liquid photo-reactive resin. This method of 3D printing builds up highly detailed and precise objects in a matter of hours.


Once the violin was 3D printed, it required a quick clean-up before being put under a strong UV light in order to completely polymerize the entire structure. This ensures that it is completely cured and as strong as can be. Then the surfaces of the violin, which comes into contact with the strings or the musician’s body, are sanded down in order to “offer optimal playing comfort”. It’s then off to stringing the instrument, a process which must be done with complete precision and care in order to ensure that it plays with the clarity it is capable of.


While Bernadac says that the violin is fully 3D printed, in actuality it isn’t entirely fabricated on a 3D printer, as of course the strings are not 3D printed, nor are the tuning pegs. However, the majority the instrument in fact is.
As you can hear in the videos on this page, the violin’s sound is as crystal clear as the instrument itself. Could SLA 3D printing prove to be the preferred printing method for 3D printing musical instruments? Bernadac’s 3D Varius may prove this to be true. What do you think about this unique, yet beautiful 3D printed violin? Discuss in the 3D Varius forum thread on 3DPB.com.

2015年第 2、3季全球PC出貨量約衰退 11.8%、10.8%,蘋果第三季 iPhone 及 MAC 成長強勁 ( 2015 PC shipment drop a lot on Q2, Q3, but Apple Inc. iPhone and MAC has a stronger shipment )

2015年第二季全球PC出貨量約衰退 9.5% ~ 11.8%

根據市場研究機構Gartner的最新報告指出,2015年第二季全球PC出貨量呈現衰退9.5%,而IDC認為衰退的現象比預期嚴重,預測衰退幅度達到兩位數字的11.8%。兩家研究機構調查結果顯示2015年第二季年成長率非常接近兩位數字,這給PC的未來又再一次壟罩了陰影。

IDC認為2015年第二季全球PC出貨量達到6614萬台。這一數字略低於IDC先前預期。主要原因在於2014年第二季,由於微軟不再支援Windows XP,因而許多消費者在這時間點讓其Windows XP升級至更新版本的系統,帶來較高的PC出貨量,這也造成2015年第二季的PC成長率不佳。

IDC與Gartner一致性的看法則是,美元匯率的增強使得其他貨幣減弱而造成PC平均價格上漲,因而抑制了PC的出貨量。另外一個重要因素是,隨著Windows 10作業系統即將推出,這讓PC市場呈現觀望的氣氛非常濃厚,所以PC通路商傾向清理既有庫存的PC產品,所以沒有向PC廠商進貨,也造成了2015年第二季出貨不如預期。

IDC認為2015年第二季PC出貨量太差並不值得擔憂。因為這一下滑的情況其實符合預期,只要Windows 10上路幾年且美元相對穩定之後,PC市場將趨於平穩。即使如此,2015年下半年PC仍將出現中低個位數比例的出貨量下滑。簡單來說,Windows 10推出的第一年對於PC產業的貢獻不會那麼明顯。

更何況微軟允許原本採購Windows 7和Windows 8.1的個人電腦用戶可以於一年內免費升級至Windows 10作業系統,因此許多用戶很可能就不會在第一年購買新PC,而是直接在舊有的PC上進行升級。到了2016年下半年買氣才會慢慢出籠。

IDC認為全球前五名PC廠商中,只有蘋果是呈現正成長的情況,出貨量達513.6萬台,比起2014年第二季的442.3萬台,年成長率達16.1%。這是因為蘋果不需要參與其他Windows PC廠商的價格戰,只要依循著自己的步調,以及透過蘋果零售商店來吸引用戶即可。

可是,Gartner似乎認為蘋果的麥金塔出貨量沒有突破456萬台,因而被排出在全球前五大PC廠商的行列之中。Gartner認為蘋果於美國PC市場,依舊呈現2.5%的衰退,IDC卻認為有11.9%的正成長。這兩家公司的爭議,或許要等到蘋果真正公布其2015年第二季麥金塔出貨量才能見真章。

PC sales drop sharply again in Q3; Apple, HP, Lenovo gain share

  • IDC estimates global PC shipments fell 10.8% Y/Y in Q3 to nearly 71M units, a drop nearly as large as Q2's 11.8% and above a 9.2% projection. Gartner estimates shipments fell 7.7% to 73.7M.
  • IDC: "Across many regions, the channel remained focused on clearing Windows 8 inventory before a more complete portfolio of models incorporating Windows 10 (NASDAQ:MSFT) and Intel (NASDAQ:INTC) Skylake processors comes on the scene ... Though easing a bit, currency devaluation continued to inhibit PC shipments in the third quarter. While Windows 10 has generally received favorable reviews and raised consumer interest in PCs, many users opted to upgrade existing PCs rather than purchase new hardware."
  • Nonetheless, IDC is "optimistic" about a demand pickup. "While PC shipments will be hampered in the short run by the availability of a free upgrade to Windows 10, the improved PC experience across user segments should drive longer-term demand for new PC hardware..."
  • Likewise, Gartner expects "more stable market conditions" in 2016. It's also pleased the U.S. notebook and "premium ultramobile" segments saw positive growth. Various analysts have reported seeing signs of stabilizing PC demand.
  • The market's four biggest players all grabbed share from smaller firms with less scale. IDC estimates market leader Lenovo's (OTCPK:LNVGY) share rose 130 bps Y/Y to 21%, #2 HP's (NYSE:HPQ) 110 bps to 19.6%, and #3 Dell's 120 bps 14.3%.
  • Apple (NASDAQ:AAPL), aided by 1H15 MacBook refreshes, came in at #4 with a 7.5% share, up 60 bps (revenue share is likely closer to 15%). A 4K 21.5" iMac is reportedly launching next week.

蘋果第三季 iPhone 及 MAC 成長強勁

Today Apple released their earnings for Q3 of fiscal year 2015, which ended June 27th. In what seems to be a never-ending sequence of records, once again, Apple posted a record third quarter. Revenue for the quarter came in at $49.6 billion, up 33% from a year ago. Gross margin was $19.7 billion, also up 33% from Q3 2014. Operating income was up almost 37% to $14.1 billion, and net income was $10.7 billion for the quarter, a gain of 37.8% year-over-year. Earnings per share was $1.85, up from $1.28 in Q3 2014.

Apple’s iPhone business has been the primary factor in these record breaking quarters, and the iPhone 6 and 6+ sales continued to be strong. For the quarter, Apple sold 47.5 million iPhones, which is a gain of 35% in units. Even more impressive is that these 35% more units resulted in 59% more revenue, with iPhone sales totalling $31.4 billion for this quarter alone.

Mac sales have also been strong, and while Apple has generally outpaced the PC market in sales growth for a while, Apple saw an additional 5% in Mac unit sales for Q4 compared to Q3, and 9% from a year ago. This is at a time where the rest of the PC market is contracting, so Mac sales were an impressive 4.8 million units, with revenue of just over $6 billion for the quarter. The resurgence of the Mac has been quite the rise, with Mac revenue being eclipsed quite a bit by the iPad not very long ago. Times have changed though and Apple’s PC business is currently the only one that has seen an increase in sales according to the reports floated around in the last couple of weeks.

iPad sales though are not so rosy. The iPad sales were very strong, and while sales are not exactly terrible, the number of units being sold has been dropping for some time. Much debate has been about why this is, but certainly owners of the iPad have not felt the need to refresh their devices anywhere nearly as quickly as phones. For the quarter, there were 10.9 million iPads sold, which resulted in revenue of $4.5 billion. The number of units sold is down 13% from Q2, and down 18% year-over year.

Services, which include iTunes sales, AppleCare, Apple Pay, and will include Apple Music in the future, saw a nice jump as well with just over $5 billion in revenue for the quarter. This is up 1% from last quarter, and up 12% from last year.

“Other Products” which is Apple TV, Apple Watch, Beats, iPods, and accessories had a big quarter, and while individual numbers were not announced, it is likely due to initial sales of the Apple Watch which came out in the quarter. For Q3, this group had sales of $2.6 billion, up 56% from last quarter and up 49% year-over-year. Likely most of the increase can be attributed to the Watch, but without knowing average selling price, it would be pretty difficult to try and extrapolate unit sales without more information.

This pipeline post is quite a bit shorter than the Microsoft earnings, but for all of the right reasons. There is less to say when things are going as well as they are for Apple right now. iPhone sales are still a huge part of their balance sheet, and seem to have no sign of slowing down. People obviously wanted a larger iPhone and sales have skyrocketed since the iPhone 6 and 6+ were launched. But I think we were all expecting this based on past performance. I think what is most interesting is how much of the PC market Apple has managed to chip away with Mac sales, which are up an amazing 9% when the rest of the market contracted.
For Q4, Apple is expecting revenue of $49 to $51 billion, with a gross margin of 38.5 to 39.5%.

蘋果雲端儲存服務也是領先群雄

蘋果 (Apple)(AAPL-US) 在眾多科技領域中,都維持領先地位。一份由 Strategy Analytics 所做的調查顯示,在雲端媒體服務,蘋果也是美國榜首, iCloud 及 iTunes Match 市占達 27%,遙遙領先其他競爭者。


分析

  • 從蘋果第三季 iPhone 及 MAC 成長強勁,很明顯蘋果是大勝,基本上蘋果以流行性、方便性及實用性打敗競爭對手;
  • 從蘋果策略上,使用過蘋果以方便性及實用性,其實會覺得 PC 確實難用又沒效率;
  • 分析發現,若 MAC 還存在 Window 雙模 OS 機種,將對 PC 更大衝擊;

從2000 美國科技泡沫看美國升息、歐、日印鈔中國大幅貨幣寬鬆之全球股市、經濟及資金趨勢 : 全球股市空頭來臨?( World wide stock already came to a bear market for each country, Why ? )

從2000美科技泡沫台股超前跌看

    回億我 2000因為先看見第一季全球手機大廠剛進入衰退,加上政黨輪替及台灣大寬頻股條事件,將長期投資4年之DVD、美股半導體股、未上市股,毅然決定全部賣出,我記得那是一次很成功的投資收益,3.5年投資報酬率超過 625%,也是我第一次長期投資成功建立經濟基礎,非常感謝聖靈在2000台股股災之一再提醒,讓我能堅定在9800附近全數賣出,記得賣未上市股時還非常熱絡大家搶著買,現在想起來真是令人驚懼,因為許多那時之未上市股已經不在了,我選股能力還需加強。

    台股周線達大M頭首波跌幅最低7203點反彈,在長空的結構中周線的大M頭至少會跌2~3波,反彈後避險最佳,九月財報、第三季季報將是反彈利多出盡時間點,還是利空罩頂?

2000 美國科技泡沫前,台股是超前全球股市最早崩盤的,這一波全球股市回檔進空頭台股是開端
台股周線達大M頭首波跌幅最低7203點反彈,在長空的結構中周線的大M頭至少會跌2~3波,反彈後避險最佳
美股道瓊週再不反彈突破就有危機

美股道瓊週線跌破趨勢線17200點,累計量短壓在17476點,短線等待財報及第三季季報,技術面跌破15925後長線的空頭開始,小心投資。

美股道瓊週線跌破趨勢線17200點,累計量短壓在17476點,空方力量主導

美股最大危機是石油相關產業,因為美國石油庫存一直高檔,中國又大幅買石油來建立石油庫存,正如 Seekingalpha.com said : Everyone knows that crude oil inventories are at hugely elevated levels, indeed, at 80-year highs,說實在聽了我真的發毛,因為美國石油相關產業牽連相當大美股之營業額及獲利,會影響財報及第三季季報。

Crude Oil: Where Is The Bottom?
  • Crude oil prices have a long way to fall perhaps to $25 per barrel.
  • There will not be a bottom until there is a serious panic in the oil market and companies perform serious bloodletting.

  • 台股、美股道瓊、德股、法股、巴西股市、泰國股市、印度股市、南韓股市、香港股市都跌破趨勢線, 25 週均線下彎之空頭趨勢,巴西更是面臨破6年頸線低檔支撐最後如何下探階段,全球是有可能發生金融風暴或倒債,在投資上要搞清楚台股周線達大M頭首波跌幅最低7203點反彈,在長空的結構中周線的大M頭至少會跌3~5波,而全球大部分股市也處於第一波跌勢,價值投資時間還沒到。
  • 全球經濟最大風險是中國大陸 
  • 全球經濟及金融最大問題是:過度投資、過剩產能、過度負債、過度依賴貨幣寬鬆及印鈔,卻忽略各國必須創造消費需求,否則,過度供過於求就是資產泡沫及通縮。
