How-To Guides

goal: provide guides that are to-the-point with sited research

This set of tutorials will cover some essentials to designing circuits and pcb layouts using kicad, an open-source tool for circuit (board) design that's free and has no restrictions on number of layers or size (like Eagle). We'll focus more on the unintuitive things as well as tips & tricks rather than re-write the manual.
kicad tutorial
The goal of this guide is to consollidate and test many of the numerous PS2 interfacing guides already out there. Included are the hardware connection requirements, software protocol (including pressure vibration motors, pressure sensitivity and guitar hero controller), and complete hand-shake traces showing everything a real play station and controller say to each other on first connect. Also includes c source code (MPLAB projects) for the PIC18F4550.
Play Station 2 Controller Interfacing
A set of tutorials (including video) showing inexpensive ways to solder a variety of surface mount components, including: fine-pitch QFPs, lead-less QFNs, PLCCs, Resistors, and more. It also includes a listing of inexpensive tools with pictures, and a tutorial on using solder paste with a toaster oven.
Surface Mount Soldering examples
This guide contains a 7 min. overview video followed by in depth discussion of picking out the right tools (how much wattage & temperature is needed? what type of solder? flux?), proper technique, and loads of hi-res, close up shots of good and bad joints.
An 8-min. video introduction to working with metal. It explains how to tap holes (embed screw threads in metal), accurately measure and locate holes, and use a variety of tools including calipers, center punches, squares, files, deburring tools, and more.
Ever wanted to know just how big a screw you need for a given application? Or what the different types are and when to use them? (coarse thread, fine thread, machine, wood, socket, lag, etc). How tight should it be? And what are washers for and when are they needed?
How fast should you set your drill press for a certain size drill bit and material?
What size drill do you need for a given tap size? What size clearance drill?
Just how big is a letter F or number 4 drill. Sizes in English and metric decimals.
