Fred points out this schematic for a rather interesting radiotelephone transmitter instantaneously powered by the operator’s voice – One of the neatest minimalist amateur radio transmitter circuits around – this one is voice powered – it provides DSB, (double side band)modulation and power from an ordinary 8-ohm speaker – if are in doubt that the […]
Dino sent us this vid demonstrating some potential audio effects resulting from landline-to-cellphone delay times. Strictly speaking “reverb” is usually considered as sound delays with no discernible separation – but hey, who’s counting? Good clean fun to try at home- would definitely be cool to see this effect taken advantage of in a live performance […]
This is the second revision of my PIC based LED binary clock. The original version was the first PIC project I attempted, it used a PIC16F84A to do both the timekeeping and control the display matrix, unfortunately it didn’t keep good enough time and gained about a minute every week.
From the MAKE Flickr pool In need of a more visible level for setting up long exposure night shots, zomie made an LED illuminated level attachment for use with his DSLR + Gorillapod setup. Check out his instructable for the step-by-step.
From the MAKE Flickr pool Augustson designed etched and assembled a specialized Arduino board for a new robotics project – What is ADM 1.0? Basically we built an Arduino, added a Dual Motor Controller to it and a small prototyping area. Hence the name ADM (Arduino Dual Motor). The board works and is programmed just […]
Peter Johansson is building a medium-format film camera. Like, from scratch. He’s about 80% done and has done a wonderful job documenting the build. [Thanks, Billy!]
From the MAKE Flickr pool Mark of Spikenzie Labs shares this simple recipe for a pumpkin cutter using a scroll saw blade and some duct tape. Looks like a good choice for those intricate/curved designs.
