Turn your old useless laptop screen into an external monitorFor far too long I possessed an old Dell Studio laptop. It served me well for a good 5 years with a number of service centre visits, battery and hard disk replacements, formats and OS upgrades. From the past few years I have ditched the old laptop for a Macbook. Yet still, I never bothered to dispose of it. After all it still works (slow af but works!). What if there is an ‘emergency’ situation where I need to use this ancient piece of technology? I tried selling it, but the act itself and the price I get for it is honestly not worth it. Giving it to someone for free feels like a punishment to the person (most smartphones have better specs). Disposing it off just doesn’t feel right (yeah right! That’s the middle class in me speaking. Also not very good for the environment).2. The Basics of The Firmware Development ProcessFirmware development is a necessary process in creating a new device and an embedded system.
