Ham Goes Nuts for Tiny Transmitter

What’s the minimal BOM for a working amateur radio transmitter? Looks like you can get away with seven parts, or eight if you include the walnut. You’ve got to have a walnut. Some hams really love the challenge of QRP, or the deliberate use of low-power transmitters to provide a challenge to making long-distance contacts. We’ve covered the world of QRP before and noted that while QRP rigs don’t throw a lot of power, it…

Old Thermometer Gets New Eyes

As much as we’d like to have the right tools for the right job all of the time, sometimes our parts drawers have other things in mind. After all, what’s better than buying a new tool than building one yourself from things you had lying around? That’s at least what [Saulius] must have been thinking when he needed a thermometer with a digital output, but only had a dumb, but feature-rich, thermometer on hand. Luckily, [Saulius]…

60 Watt USB Soldering Iron Does it with Type-C

Some time back we ran a post on those cheap USB soldering irons which appeared to be surprisingly capable considering they were really under powered, literally. But USB Type-C is slated to change that. Although it has been around for a while, we are only now beginning to see USB-C capable devices and chargers gain traction. USB-C chargers featuring the USB-PD option (for power delivery) can act as high power sources allowing fast charging of…

A toast-buttering robot for your breakfast routine

Tired of buttering your toast in the morning? Well, William Osman has just the solution for you, albeit slightly dangerous and excessive for the task at hand. For his “extremely violent” machine, Osman used a jigsaw motor to hold the butter and an Arduino-driven linear stepper motor to move the slice of toast back and forth. The robot’s frame, spikes, and […]

Power a 1980s MicroVox with an Arduino Uno

After digging through an extremely complete manual, Monta Elkins used an Arduino Uno to make a MicroVox speech synthesizer do his bidding. The bad thing about obsolete gear is that it is generally very hard to hook up to modern equipment. The great thing for Makers, though, is that many of the devices from one’s childhood (or before) […]

Turn an old mixer into a MIDI input fader with Arduino

Using an Arduino as an HID, Evan Kale turned a “gently used” analog mixer into a computer interface. Older audio equipment may not have the interfaces that you need to make totally electronic music, but they can be very well-built, so are perhaps worth salvaging. In the video below, Kale salvages potentiometers from an old mixer, then […]

Have you seen my new lift ticket?

Over the past year more and more ski resorts in Colorado have started to use RFID based lift tickets as opposed to the classic sticker-on-your-zipper-pull. To me, this is great. I no longer have to have thing flopping in the wind while I ski, that I have to chop off at the end of the day. I stick the plastic card in my pocket and the lifties scan my torso with a RFID scanner and say ‘Have a good run Nathan’. I’ve been…
