    usb project

    First decide upon the USB microcontroller you r going to use. Atmel, Cypress & Microchip provide them, Phillips provides a USB interface chip & FTDI provides a USB to RS232 bridge. I think the factor of chioce will be cost. Dose anyone knows a low cost usb controller?

    Best design software and board lab

    At first you may find Eagle frustrating. But withine one or two hours you can master it. It is the best free package around if you r into making PCB's.

    Dose your LCD rolls?

    Okey i has one 89C52 based project which measures displacement by using an incremental rotary encoder & displays it on 16X2 Alphanumeric LCD. I purchased a 230V -> 5V SMPS to power this thing. And guess what the LCD started rolling :o I replaced the SMPS by trusted X'mer & 7805 &amp...

    My computer is slowing down!!

    Norton system works is grate for all windows ver. It is a good tool to recommend espically the 'speed disk' (the defragementor). It is lightyears ahade of the default defragmentor that comes with windows. If you have NTFS then i don't think you should even need to defrag often.

    Are you using WindowsXP? If yes then you should find the folder at D:\Windpws\Prefetch . On my machine it is not hidden. Clear it when you do major changes to your system (like install/uninstall spree:)). This folder is used by windows to preload the programs you use on your PC. However windows...
