Speaker design master Curt Campbell has created several dream kits for the audiophile, including the TriTrix. Featuring two 5.25″ Dayton Audio woofers and a single tweeter in MTM format, the final product has an easy, 8Ω load that can be used for audio or home theater systems. The transmission line kit includes precision-cut MDF for making the cabinets, […]
Just one listen to this home-built, high-end tube amp, and you’ll quickly discover that there’s more to that classic song you’ve been listening to for years. It has nothing to do with nostalgia — tubes just sound more musical than pure solid state, and the PoddWatt is a prime example. So, what can you get from a […]
The great thing about this kit is the variety of skills you’ll learn. Not only do you end up with a warm-sounding tube amp, but you also learn how all these audio components are produced, as well as proper soldering technique, orientation of polarized capacitors, spacing of large-value wirewound resistors, and heat sinking of transistors. […]
This kit gets top marks for ease of assembly and low price, and because it’s preprogrammed to do all the heavy lifting, all you need to do is solder it together and attach it to the device of your choice. It’ll take an average-skilled solderer 1½ hours to assemble, and from there the possibilities are […]
Karol Łuszcz is studying electronics at Poland’s Gdańsk University of Technology. I’d say he’s on-track for an impressive career. This vector-graphics laser projector, his third prototype, includes three laser modules at 650, 532, and 405 nm wavelengths (making it more of an RGV projector, really). Many parts were salvaged, for instance, from a DVD burner, a printer, and a “disco ball.”
Back before cell phones had full color displays they used highly readable monochrome displays like this one, now available in the Maker Shed. These small (1.5″ diagonal) displays were originally used in old Nokia 5110/3310 cell phones. They feature a white backlight and 84×48 individual pixels so you can use them for graphics, text or bitmaps.
Congratulations to Joseph, winner of the latest Weekend Projects giveaway. You get a Maker’s Notebook and a Mintronics: Survival Pack (above). The Mintronics pack includes many of the components that we’ve been working with over the past few months in Weekend Projects. And with the notebook, Joseph will be able to jot down his project ideas in the years ahead.
