事情大致上是這樣的，因為現在在用的那個自制尿袋（內地：充電寶）已經用了好幾年了。 就是這一塊電池，是由2014 年頭的時候買下的，到現在都不知道經過了多少次充放循環了。 而且原本的尿袋也有很多很多的問題，好像是插頭不夠（當時想著一個插頭充手機就足夠了，可以之後用著才發現還有平板電腦、藍牙耳機等等好多東西要充，根本不夠位置），而且當時設計的時候插頭只能輸出1.2A，既然是這樣不如重新設計過整個尿袋吧？ 想著都已經經過這麼多年了，技術力也提升了不少。這是以前的線路： 就是這樣解單，一塊充電板、一塊升壓板和一個開關制。 這是現在的線路圖： 你說這些技術是哪裡學回來的？嗯，就是 Minecraft 紅石啊。遲點有機會的話我會說一下如何把 Minecraft 裡的紅石轉成真實電路圖，但是這次就不說這麼多了。 經過好幾晚的研究，讀Datasheet 跟做一點試驗之後，終於得出了這個設計。你要知道作為一個野生技術宅，設計甚麼的我可是不太在行。所以參考了某些日本技術宅的設計，最後就把設計圖改成這樣。 好吧，之後就是落實生產。下一次跟進可能已經是一兩個月之後的事情，再看看到時能不能做到相似的成品吧~~

Project Introduction Power Bank usually output at a Voltage of 5V with current up to 2.1A (MAX), however in some cases, when you want to charge a bit faster, increase the current will not help as most of the devices usually draw up to 1A (MAX). Hence, if you want to charge a bit faster and not afraid of damaging your devices, you can try to use the Hyper Charge approach. Explanation Hyper Charge is just a random name for the technique that rise the voltage of the output USB port by 0.5V to 1V. Hence, the maximum power delivered to the devices will be increased from, for example 5W (5V 1A) to 6W (6V 1A). Hence, the devices should thermostatically charge a bit faster.

  Project Introduction Power supply usually is a problem that occurs when you go camping or long period of outdoor activity. The time that this power bank was made, the common power bank volume you can find on the market has a maximum of  10000mAh. That is quite enough for daily uses but not for those who go camping every years. Hence, I made myself a giant power bank with solar charging system. Explanation During camping, there is no electric plug for charging your power bank. Hence, I need to find an alternative sources of power supply which Solar power come into my mind. We all know that Li-ion Battery will lose its stored capacity during unused period. And the solar panel on top was to reduce the energy lose by continuously charging the Battery just to refill its energy lost.

Project Introduction Hologram on youtube or instructables are always a hot topic. You can buy those cheap Hologram stand for a few dollars, but actually, you can make your own. Due to the over simple mechanism of this DIY project, I better just post pictures and let yourself to decide how to make it. The back of the Hologram Screen     Side Views with our Old Logo Explanation You can see the thin transparent screen makes a 45 degree angle with the bottom card board. Hence, when you place the mobile phone onto the screen, the light reflects from the screen and create a Hologram like image. You can also change the black background to other image just to look cool. Specification 7 inch 1mm thickness Full transparent Aquatic Sheet   Project Ended in 28/8/2014

IMUS Laboratory Product Development and Prototype Resale Welcome to IMUS Laboratory PD-PR web page. This post will explains how this page works. Basic work flow Tell us what you want to make, the more detail you give, the better the results and pricing accuracy. Tell us your target pricing or the amount you are willing to give for this prototype. MAKE SURE YOUR REQUEST IS "DESIGN SKETCH ONLY" or "PROTOTYPE READY" We will provide a rough pricing for your prototype (The final pricing may be greater or lower than the expected price) If you agree with the price, the project will be started. If you disagree with the price, you can try removing some functions or cancel the prototype request.
