Surface mounting with hand-soldering tools

Surface mounting with hand-soldering tools

Pcb3SolderpasteGood how to on surface mounting with hand-soldering tools. “Integrated-circuit (IC) manufacturers produce fewer new designs in dual in-line package (DIP), shrink dual in-line package (SDIP), or other through-hole forms. These are the classic looking chips that have legs that extend through the circuit board and are soldered on the other side. They’re easy to put into sockets and easy to use on solderless breadboards. Most of the new families appear only in surface-mount technology (SMT), surface mount device (Philips SMD), or surface mount component (SMC) packaging such as small outline integrated circuit (SOIC), small outline J-leaded (SOJ), small outline transistor (SOT), plastic leaded chip carrier (PLCC), quad flat pack (QFP), or thin small outline package (TSOP). Without special adapter (carrier) boards, surface-mounted components make breadboarding and hobbyist experimentation difficult.” Thanks Greg! Link.

HOW TO – Make a Digital Pinhole Lens

HOW TO – Make a Digital Pinhole Lens

Pinhole Camera“One of the oldest camera forms is the Pin-hole, or “natural” camera. The pinhole camera was mentioned as early as Leonardo DaVinci in his Codex Atlanticus and Manuscript D. The term Camera Obscura or “dark room” was first used by Johannes Kepler who used the term to describe a dark room or box with a small hole used by artists to draw landscapes, it wasn’t until the 1850’s that the first photographic pinhole image was created.” Here’s how to make one for you digital camera. Thanks Greg! Link.

HOW TO – Build your own Ring flash

HOW TO – Build your own Ring flash

Ring Flash 8“One of the cooler lighting effects that we have left over from the 90’s era fashion photography is the use of Ring Flash as a primary light source. Ring flashes are often used in either fashion photography or in macro photography where the ring of light helps to eliminate shadows. When used in fashion or generally people photography it has the effect of creating a flat but almost iridescent lighting quality with a ‘halo’ effect around the subject. Cool yes, cheap? No. Flashes designed for macro photography generally will set you back about $400, while ring flashes for medium format and intended for fashion photography cost well over $1000!…Well fortunately, building your own ring flash is a fairly easy project with results that can easily rival professional ring flash assemblies for only a fraction of the price.” Link.

LED Lights for your home…

LED Lights for your home…

Borealis Sq SidebarExcellent write up of a Maker who created a beautiful line of low power LED lighting for your home, and now they’re for sale – “The light I built for my dining room has three 1W LEDs encased in clear rod, surrounded by transparent blue plastic. This means that the light shines downward with white light but glows out the side in a very nice blue. I built it for our dining room and so I call it the dining room light, Eurolite has come up with their own names for the lights and this one is the Borealis Linear.”Link.
