传统捕鱼方式

不久前,我钓了一天很糟糕的鱼,因为我的煎锅或冰箱里有东西吃。同样的故事也发生在离我几米远的老家伙身上。因此,我们决定花些时间聊聊我们以前捕获的记录鱼。当老家伙换鱼饵时,我注意到他在L端没有鱼钩。伊恩……那个装置是什么?你怎么用它捕鱼?老家伙笑着说,他也经常去打猎,总是不让鹿角碰到鹿之类的东西。他不是用钩子,而是用一个圆圆的尖杆,中间有一点缺口。他不知道这怎么可能会钩住鱼。所以这次笑得更大了:(“放松拳头,把它放进去,然后拉到绳子上。“他说,我很傻,以为它不会起作用:(通过两个流血的刺来弄清楚……鱼把“棍子”吞进诱饵里,一个有一个钩子,一个尖头总是会被卡住。另一个移动,直到没有移动的空间了,鱼被钉住了。只有道nside是指一条鱼太大了,可能抓不到——倒霉的是,用这种方法来代替钢钩,让我想起了我祖父以前做的竹竿。是用来钓鳗鱼的吗?鳟鱼,鲤鱼,甚至是从船上拿鳕鱼和沙丁鱼,他都很喜欢他的竹子。甚至让我用一根竹子做了第五根飞钓鱼竿:)然而,这个老人有很多手工制作的鱼竿或角针作为鱼钩。当他的手仍然像眼睛一样好的时候,他甚至用这些角棍做了苍蝇!他向我解释了这个过程,但我从来没有耐心去做正常的苍蝇,用角棒做这个,估计最大的鱼可能有多大,同时确保它既不太重也不会浮起来……我真正喜欢的是这个浪费掉的捕鱼日是我从老人那里得到的故事。“你不需要幻想或结束。”灵敏的渔具,如果你饿了,一个安全别针和一些包装袋就可以了!”最好的故事是,他是如何用手钓线钓到一条2米长的沙丁鱼作为诱饵的。我真的可以帮他打3个小时的船。哈哈,什么是你最成功的老派,或者只是用一个真正的体育渔夫都不会碰的东西来钓到的?

电池组和太阳能电池-可以很好的指导你去做!

我很幸运地从当地的折扣店买到了一个漂亮的、真正的8000mAh的太阳能电池组。我开始怀疑,认识到太阳能电池与其说是真正的用途,不如说是一个花招……我们都喜欢我们的移动设备,真的讨厌它们需要不断充电。在长时间的户外旅行中,人们常常携带大量的装备和重要的辅助设备。谎言。在今天,似乎太阳能和电池开始取代食物和水。没有照片,旅行就不完整。自拍和录像,some even take a drone with them.So: are there ways to increase your luggage weight by thinking smarter?Modern technology has come a long way and moves faster ever year.Solar cells are no exception here.Be it foldable setups or now even roll ups of flexible cell systems,you have the total freedom of coice.But then again: You are going on a week long camping trip in the middle of nowhere...Going on foot or using a bike means you need to keep the extras down or hire someone to carry them.Here are some of my yet to be finnished ideas:As long as you don't use them commercially feel free to make an Instructable or just use the ideas!1.弹出式和普通帐篷。他们现在似乎是新的标准。大的,里面没有杆,甚至是从未使用过帐篷的人都可以设置它们。有了这个设计,就有了一种折叠所有东西的方法来包装它。灵活的太阳能电池设计不会破坏,通常可以被安排,这样他们就能够真正地替换部分外部帐篷。材料。如果这可能意味着他们会扭动太多和太频繁,他们仍然是完美的创造一些“带子面板”,可以卷起,并包括与你的泡沫垫或床垫。一个200或甚至400 W系统可以运输方便,重量比80W折叠解决方案,你挣扎着确保你的背包或B。艾克。2。追踪器!现在几乎是固定安装的标准,但在移动设置中仍然看不到。您会弹出面板,connect the power packs or batteries and go fishing,徒步旅行之类的。太阳继续移动,太阳能电池板的效率受到影响。这些太阳能跟踪器有很多很好的IBL,from simple to 3 dimensional.Kites loves to use carbon fibre rods to reduce the weight.A tracking frame to hold a good sized flexible panel would count at less than 300 grams....In return you get up to 40% higher effiency and overall output compared to a fixed panel!Roll the panel up,fold the frame and you end up with a quite small roll that is easy to transport and very low in weight.3.电池备份。不管你计划了多长时间和多久,在旅行开始后不久,天气可能会让你失望。对于很多人来说,这没问题。但是,电力不足会导致一些人努力保持他们的视频记录运行。你的小型无人机可能很棒,但它只持续不到30分钟,直到你需要新的电池。如果你使用稳定器,类似的故事也会发生。automatic tilt and pan gadgets or just a 360° camera.Just your cell phone alone can be a hassle if you use it as the main thing for GPS,图片和视频。现在至少有一组备用电池是必须的。对于很多事情来说,这确实很有意义,for others not so much.Unless you really need ongoing power it might be enough to just charge you empty battery at the end of the day.But then the sun is down and options are gone for solar energy.In the RC area we can find a lot of powerful battery packs.Usually around 14V but 40 or more are no problem.And if you check the E-bike and scooter sections you will find some quite powerful and light weight battery packs.If you go outdoors a lot and for longer periods of time then it makes sense to replace the multiple battery options with just a single one.Use a high power backup battery with your solar system.DC-DC converters make it possible to literally combine everything with everything.Select the battery size so it will suit your charging needs and capabiliteis of the solar setup.Once time to close the tent you enjoy electricity to finnish your logs while your batteries are being charged during the night from the backup.4.Emergency generator.We all know these cheap gadgets like crank up torches or cranking mobile phone chargers.Nice to play with,utterly useless if you actually have to rely on them.A full charge for your modern phone might mean you crank for at least half the day - good luck!If you already carry a supply of gas for your cooking needs then these new fuel cells running on butane might be nice.Some of the Kickstarter projects actually made it into production!Prices though are more for real fans or those with enough money...But a small RC engine can drive some nice DC motor with very little fuel....In return you get a pocket sized generator that can charger your phone fully in the same amount of time a wall charger would...

现代生活的代价和缺点

在另一个主题中,我们注意到时间在维修方面发生了变化,备件或者只是找个替代品。许多人似乎不再费心去修理他们破碎的东西,而且对于那些仍然想有选择的人来说,这些东西正在迅速消失。以普通的草坪搬运工为例:我们可以在专门的商店里买到,当地的五金店,supermarkets and sometimes even at Aldi.But if you need such a simple spare part like a fuel hose or gasket for the carby you are usually lost unless you can order the parts from some online store at the other end of the world.电子设备更糟,在这里,一个坏的充电插头或只是松开充电器就意味着人们把它扔进垃圾箱去买一个新的设备。剪断绳子?如果一大捆绳结做同样的棒棒糖,何必费心呢?你还记得那些修理你的Waching机器的小修理店吗?TV or sometimes even your electric drill?他们现在在哪里?Or all these small electronics shops selling resistors,电线和成套工具?I still remember the times when I could take my radio to the local shop,the guy listens to the sound and lack of available stations and knew right away what parts I needed - and they were right at hand.For a few bucks extra he even replaced the broken bits if he had the time.在考虑了这些之后,我开始意识到两件事:a)我们变得懒惰,不再学习重要的技能,因为现代生活使我们认为我们不再需要这些技能。b)除非你能自己修理,劳动力成本意味着修理往往不值得。谁在这里?under the age of 30 still knows how to make a good campfire from scratch,dares to take the lawnmower apart to fix it himself or simply bothers to stich up a little rip in his fancy tent instead of buying a new one?For crying out loud,很多孩子甚至不知道如何操作洗衣机的时候,租赁父母家永远…学校似乎不再教授使用钢笔和铅笔来支持这些生活变化,更不用说墨水了…孩子们得到的只是一台平板电脑或笔记本电脑,这意味着他们甚至不需要再学习语言——这就是拼写检查程序所做的。如果我敢再旋转25年左右,我只会看到混乱。每个人都非常专业,noone bothers to cook anymore and the third generation in the family no longer has any clue what the first generation is talking about.When my grandfather grew up life was hard.When my parents grew up life was all about expressing yourself.When I grew up life was intersting because everything was changing so fast.当我的孩子离开家时,他们会怎么说?…你怎么认为?How much has modern life affected since you grew up?当然:你认为这是正确的趋势吗?

can you help identify kite parts

我想知道是否有人能帮我辨认出一些风筝部件。我在当地拍卖会上赢得了很多,包括字面上成千上万的风筝制作部件。(I have a lot more not imaged here) Unfortunately, I have little experience with kites and the scale of the volume I have acquired is a little daunting.所以我想我应该向专家寻求帮助:)到目前为止,我认为我已经找到了以下几种:22000 4毫米的端盖6000 3毫米的Spar/EAP 1500,我认为小道格(黄色的东西看起来有点像弹壳)。它们也可能是端盖,但我完全不知道这一个)500橡皮筋6000 5毫米端盖3000 6毫米端盖8000 3毫米橡胶槽色调的名称标签我知道有许多缺口端盖,我认为弯曲的塑料位是3个杆可以连接称为二面体。65 kites The fabric parts of around 10 large kites made by greens of Burnley (a lot of them branded as the pioneer range) I haven't measured but im guessing around 9ft across I think the lot originally came from Greens of Burnley who are no longer trading but I have found their archived site https://web.archive.org/web/20060818054031/http://www.greenskites.com/spares.asp If you could help by identifying some of the parts/ what the pioneer range of kites is possibly a place where I can sell some of the kit (there's far to much for me to work with here) I would be relly grateful :) PS ill put up more photo's if anyone is interested.  PPS I have just found some info on the Greens of Burnley kites http://www.ebay.ie/itm/Vintage-CODY-War-Kite-1-GREENS-KITES-Greens-of-Burnley-Large-Frame-Box-/401079737121 PPPS I found the original image I think I have a few boxers from the range. http://www.kitelife.com/wp-content/uploads/2012/01/Kite-Lines-v7-3.pdf

Making this ethereal paper bird lamp

I wonder if anyone has any suggestions on how to build a lamp that looks something like this (Perch Light by Umut Yamac).这一个是由档案纸和固态发光二极管。I can't tell whether it's nothing but folded paper or has glued components.

Fire Glove

Ok listen up guys,我有一个科学项目,我真的很想做这件事,但我担心我的手在这个过程中可能会严重受损。我想做一只手套,在那里我可以折断我的手指,用某种打火石产生火花,然后用像木材之类的燃料源点燃火焰……我正在考虑买一个耐热手套,这样我就不会被活活烧死,但是任何想法都会有帮助。
