I have plans on making a compact noise canceling DIY ribbon microphone from scratch. All the 3D models are done (most of it will be 3D printed) and it ended up being quite neat. But its structure itself poses a big problem. Since it's small, the 2 transormers (2 ribbons) end up being too close...

Hi hackers and DIYers I have a Lenovo Y50-70, and I am really satisfied with it.. except the battery life. The original one has a 54 Wh battery that can get support me for 4 hours... not enough for a days work. So I decided to do some modding. I bought some 18650s 3000mAh each, and want to...

Hi I seem to either have terrible luck or have very bad choices and have gone though a HP, Dell, Toshiba and Acer Aspire laptop in the last 5 years. They seem to just give up and die, mainly a motherboard (and usually unresolvable issue). I always have some sort of virus protection but not sure...

I replaced the LCD screen of my laptop to fix a burnt out backlight bulb issue, but now when I turn on the computer it stays at a blank blue screen. I've tried resetting the PRAM and it stays blue trying to hold down the command keys too. I inserted my OS installation disk and nothing still...
