Introduction: LED HDPE Plastic Handbag

I've been saving the 1L HDPE bottles for a while now, mainly because once you cut off the top and the bottom, you will end up with a nice, straight piece of relatively thick plastic that can be easily shaped and welded into all sorts different things. And so I decided to make another handbag for those who liked myfirst one, but don't have a sewing machine. Here goes ;)

补给品:

Tools:

  • 剪刀
  • craft knife
  • soldering iron (I tend to use a separate one for welding plastics)
  • needle & thread

第1步:瓶子制备

我开始砍掉瓶子的顶部和底部,并彻底清洁内部仍然留下任何液体。

Next I printed out the template and moved onto the fun part.

第2步:徽标和切割

使手提包看起来更有趣,我决定用设计标记将我的徽标绘制到它上。如果您想复制此项目,我将在模板中留下一个空格,为您绘制自己的设计。

追踪我用工艺刀。我开始将塑料表放在模板上,用透明的胶带固定它并用工艺刀轻轻追踪线条。

对于我预期使用剪刀的下一步,但得分的塑料真的很容易弯曲和用刀切割,从而留下更好,更清晰的结果。

为了保护用标记绘制的设计,我涂上了一层聚氨酯工艺清漆,否则会很容易地划伤加班。

Step 3: Bending

Before welding the handbag together, I proceeded to bend the pieces along the scored lines. Most of these were inward bends apart from the very top of the front and back pieces where the handles would later be attached to and the top of the inner wall. For these I bent them inwards first and then outwards.

第4步:电路

For this step I started by uploading the code to the Arduino and attached the header pins, so that the code could be easily re-uploaded later.

我希望袋子里的所有电子产品有固定位置,但随着开关,充电器和arduino仍然可以轻松访问。所以我决定将内墙右上角的开关用它旁边的充电器和Arduino恰好在充电器下。

为了做到这一点,我将一个足够大的洞,使开关滑过内壁,并用针头和螺纹将开关缝合到内壁上,以将其固定到位。接下来,我将两根电线焊接到开关上,并通过开关和内壁之间的间隙推动它们。这些电线比附着在充电器上的正输出和Arduino的VCC引脚上。另一根电线将充电器的负输出连接到Arduino的接地销,然后为电池提供两根电线。

Next I soldered the two wires for the push button onto the pin 2 and ground pin and three wires for the LEDs onto the pin 6, VCC and GRD pin.

To make sure everything works as intended, I attached the wires onto the LEDs and the battery and shorted the push button wires. To make the soldering onto the battery easier and avoid applying too much heat I gently filed both ends of the battery with a nail file.

Since everything worked as desired, I removed the wires from the LEDs and the battery and stitched the charger and Arduino to the inner wall.

Step 5: Welding

HDPE(高密度聚乙烯)的熔点是130℃,因此我将烙铁设置为约280°C。我发现这是在不得不等待长期和燃烧塑料之间的甜蜜点。此外,我并不真正了解自我焊接铁的确切温度,这是廉价的,它们在精确的温度部门并不是很可靠。我拥有一些焊接铁杆,这个是不再用于它的原始目的。因此,如果您决定制作自己的包,我会建议使用废物碎片进行一点测试,并相应地调整温度。

我想确保袋子中的所有电子产品都会受到保护免受任何意外短路的保护,因此我采取了更大的废料并为USB,Switch和Arduino报头切出孔。

To begin the welding process, I slid the cover over the header and aligned it with the inner wall, then I poked a lot of holes through the two plastic layers with the tip of the soldering iron to create a strong joint. Then I attached the hood for the Arduino headers.

接下来,我对齐前部和侧件的底部边缘,并沿着内部的重叠焊接。对于侧面,侧面用前部向上铺设片,然后我夹住侧件的边缘并与前件的底部边缘对齐并从外部焊接。我在另一边一直对齐和焊接两件并重复。一旦两侧被竖立,我就可以从内部焊接前部的每个标签。

When it comes to creating shapes from plastic sheets, you can pretty much treat it as a paper craft project except you would use heat to create a bond instead of glue.

Step 6: Inner Wall

To keep the wires organized and out of the way, I cut the inner wall tabs wherever necessary into smaller strips and used those as wire fasteners.

在将内壁安装到袋子之前,我将一些双面胶带涂在LED条带上,缩短并焊接来自Arduino的电线并将其连接到前部的底部。然后我将内壁焊接到袋子的底部,并进行以对齐并从外部焊接内壁的每个突片,然后从内部焊接。

Next I shortened and soldered on the battery wires and made a small battery cover.

第7步:调整

Upon turning on the LEDs I found the electronics to be a little distracting and so I decided to cover the inner wall with a piece of white plastic sheet salvaged from an old monitor, stuck onto the inside of the inner wall with some double sided tape. This could be easily substituted with any white sheet. Once that's done I secured the top of the inner wall onto the top of the front piece from the outside.

接下来我将袋子的底部附着并从内部焊接并焊接侧面。之后,我用剪刀切断突出侧面。

第8步:快速紧固件

For the closing mechanism I decided to go with the sew on snap fasteners. I cut two small holes on the back side of the bag for the bulging parts of the fasteners to sit in and welded on the handles to the front and back of the bag. Next I sewed on the fasteners and welded on the bottom piece of the bag.

第9步:完成

要完成关闭,请将一个小矩形切入顶层,旁边的按钮的背部紧固件旁边。我从剩余的塑料纸上切割了一些较小的条带,并用它们来固定推动按钮线到位。接下来我缩短了电线并将它们焊接到按钮上。最后,我用矩形开口切割另一个小块塑料,并通过按钮焊接到按钮保持到位。

Step 10: Final Thoughts

I love how the handbag turned out. I manged to get 22 hours of continues illumination on a 5 hour charge, but this will hugely depend on the battery itself. This bag could be used especially if you like to stand out in a crowd or as a safety measure on those walks home at night. It could also be used as a night light since it gives enough light to let you see where you're walking but it's not blinding. Also the cost of making the bag is very low since most of the items necessary could be salvaged from the recycle bin and broken electronics.
