This poster is about the start of JSPB-Build and Battle (simply known as BNB), which is a course in cooperation with Masters of Lego. The founder of this class told me that we needed a gun for kids that wasn’t too heavy, easy to load, could be modulated and could fire at least three bullets. This resulted in the birth of Build and Battle Mini Hopper.
這張海報是JSPB-Build and battle(以下簡稱BNB)的開端,是與玩樂高手合作的課程,這個教室的創辦人跟我說,我們要給小朋友使用的槍不能太重,然後要容易組裝,模組化,最少三發子彈,因此誕生了Build an battle mini hopper.
This design is where I tried the hopper clip for the first time. This kind of design is quite modern from a homemade aspect. If you are interested, you can search for the article “DIY: Hopper Clips” by Ryan201821 on the NerfHaven forums. This kind of design has quite a long history behind it. Its biggest merit is its simple structure and it allows shooting many rounds without active mechanisms.
這是我首度嘗試使用Hopper clip的設計,這種設計在Homemade的領域是相當流行的,如果你有興趣可以查看nerfhaven的論壇Diy: Hopper Clips by:Ryan201821這篇文章,Hopper clip這樣子的設計相當悠久了,它的優點就是結構簡單,不須活動的機構就可以達到多次發射.
The most important thing about BNB’s design is that it gives even more space for people to use. It’s not the same as the JSPB Pro2 as its range is quite small because the resource allocation of the power system is very delicate, if the air is either a little too much or too little, it would lead to malfunction. However, with the BNB, you can make adjustments. The picture above is the HPA (high pressure air) prototype. It contains a specific design that can bypass air, allowing it to rapidly fire three rounds. However, this is only the prototype. So when the third round fires out, the pressure lessens. Therefore, you have to modify it by using a larger air tank.
BNB的設計最重要的是可以讓人有更大的發揮空間,這不像是JSPB Pro2一樣,JSPB Pro2能夠更改的範圍相當小,原因是動力的資源分配起來環環相扣,只要空氣有一點太多或太少都會導致運作不正常,然而在BNB的設計理念則是你可以更改它,在上圖呈現的是HPA(high pressure air)的實驗原型,裡面有個特殊設計可以讓空氣分流,因此可以連續發射3發,不過這只是原型設計,在於第三發的時候威力會衰退,更改更大的空氣瓶就可以改善了.
Accuracy is very important for a launcher. There is no doubt that using fishing line is a good method. However, besides fishing line, is there any other method used to spin the darts? I’ve tried six different designs attempting to use the air and its direction to change the path of the darts as well as avoiding fish tail. However, after experimentation, the previous use of the fishing line achieved the best result so this kind of design is still valuable for the future designs.
準度是發射器相當重要的一環,然而使用魚線固然是個好方法,除了魚線之外,還有沒有其他方式可以讓Darts旋轉呢? 我試了六種不同的設計,利用空氣的路徑與方向去改變Darts的方向以及防止Fish tail的設計.但是實驗結果顯示,目前釣魚線還是最有效果的,然而這些設計在於日後仍然是有價值的.
The design of Homemade’s Hopper Clip has a problem where the darts cannot be loaded or it is double feeding. The problem is that at the moment of percussion, the air has already taken off along with the dart. The plastic tips on the darts have very strong friction, which doesn’t flow smoothly sometimes. Usually, using large amounts of air is able to solve this problem, yet too much air will lead to double feeding. In order for the darts to pass through smoothly, my design’s hit point has been moved way forward. That way, it can use the plastic dart tips to seal the chamber, and then the power from the trigger passes through the chamber. It’s quite smooth when these steps are taken separately. The picture above is the Beta version, where the air vent’s incline design adds funneling space allowing the darts to spin.
Homemade's Hopper clip的設計有一個問題就是容易出現沒有Load到dart,或是Double feeding,這問題是擊發的瞬間,空氣已經先跑走然後再把Dart帶走,Darts的塑膠頭部會有強大的摩擦力,有時候會不順暢,通常使用大量的空氣就可以解決,但是大量的空氣又會造成Double feeding.為了讓Darts流動更順暢我設計的擊發地點往前了不少,這樣子可以利用橡膠彈頭去密封膛室,擊發之後的力量再去轉彎進入槍管,這些步驟分開進行後相當流暢 .上圖是Beta版本,出風口的傾斜設計加上漏斗空間可以讓Darts旋轉.
This is the latest version, which uses multiple directional air holes to create a vortex. This version compared to the previous one is more flexible and smooth. It can also provide more spin. The trigger design carries a 1:1 design from the Beta model. In order to increase eruption power, the design has changed to a leverage design, making the trigger lighter when pulling.
The logo on the left was about the initial emphasis on “cyclone power”. It stresses functionality but doesn’t appeal much to people, so it has been redesigned with some trendy elements. Eyes have been added to the check valve to make people think of a mascot. The name emphasizes the experience of “Build & Battle” because it is a DIY set.
左圖Logo是一開始強調的Cyclone power,強調功能性,但無法讓人印象深刻,因此重新設計,加入了潮流元素,在check valve上加了眼睛,讓人聯想到吉祥物的概念,而名稱更是強調使用者"建造與戰鬥"的使用經驗,因為這是個DIY的套件.
The cartoon eyes give the BNB more personality, making it trendier.
This time the glue used in the Pro2 strong enough, such as the removal of the pump when the Air tank will be loose, it is recommended to use a stronger glue to connect, you can also save AB mixed time.
How to choose glue? Pipe material for the PVC, the use of plastic for plastic, waterproof function of the plastic will be better to reduce the probability of leakage.
在2/12 過後的訂單, 我們不再提供膠水,這次提供的膠水使用於Pro2強固性不夠,例如移除打氣筒的時候,Air tank會鬆脫,建議使用更強的膠來連接,也可以省去AB混合的麻煩.
