Hi there, I'm Pierre from France, an electronic maker. For some time now I have been working on a reasonably sized smartphone. Because today there're not any manufacturers making small smartphones anymore. But lot of people are complaining about smartphone big sizes. So I created the project OneDevice, which feature a compact 5" LCD with only 118mm height. You can check it out on www.onedevice.eu Today the development of a smartphone is not difficult, the only problem is to reach enough people in order to interest OEM manufacturers and components manufacturers (Processor, screens...). I think this project will interest lot of your readers, as we had a first article in a french media which raised a lot of interest (https://www.frandroid.com/produits-android/smartphone/651099_ce-francais-veut-relancer-la-mode-des-petits-smartphones-de-5-pouces). If you like this project, writing about it will help it becoming reality! :) Thanks and have a good day, Pierre

Hello Everyone, I am trying to build a mobile phone charger (For my Samsung phone) by myself using following components. Step down transformer (from 230V to 9V 1200mA) Bridge Rectifier 1000uf capacitor (To smooth the DC voltage) 7805 Regulator (To get output voltage 5V) A micro USB cable I got from a broken charger. Appreciate if you can share your thoughts regarding this. Will this harmful to the phone or will this work better than the low quality Chinese chargers?
