Our friend Arjan van der Meij made this charming musical instrument from a signal generator, a servo motor, an Arduino and a processing program. He wrote an instructable for it so you can build one, too.
He also wrote about his experience with the project in Dutch on makered.nl. Projects like this one, that started with a question (“Why don’t you build a machine to do it?”) are great for learning new skills. I often get asked what things someone should get for learning electronics, and my answer is usually that the first thing you need is a project that you want to make so that you’ll have motivation to research what you’ll need.
Arjan wanted to learn tinkercad, and used this project toward that goal by modeling the knob adapter he’d need for connecting his servo to his signal generator knob. Even if you don’t want to make a musical instrument from a signal generator, this project may provide inspiration for trying out new techniques.
We’ve been working on the MOnSter 6502 project for quite some time. We first introduced it last year, and since then we have brought it up to the stage of successfully running programs in assembly, BASIC, and Forth. We have taken this opportunity before Maker Faire to put together an introductory video for the project.
The folks at Mouse-Sensitivity.com used the AxiDraw to do a mouse sensor accuracy test, comparing the Logitech G900, G700s, and G9X (and a cheap HP they had on hand). The resulting visualization of the sensor information is fascinating!
Historically, these machines were programmed with semi-transparent picture cards which were scanned by the machine line by line. For later machines, you could enter a pattern via lots of tedious button-pressing. Some models had an add-on gadget that connected to your vintage TV.
With the AYAB interface, you can provide an image of up to a 200 pixel (or needle) size from your computer. The control is done by an Arduino-compatible microcontroller board, which replaces the vintage control board. We are excited to be helping to bring new capabilities to these beloved machines.
The makers of OSHChip are now producing the IC pins on their own for you to use in projects where square header pins just aren’t a good solution. The larger header pins can damage breadboard sockets, but Flip-Pins are the same size as traditional IC pins.
We’re stocking these elegant parts in packs of 10 of each of the available sizes: 8-pin, 14-pin, and 20-pin strips.
They come packaged in a carrier strip for ease of soldering into your PCB.
While I’m a big fan of paper and circuits, I’ve never really given paper circuits/circuitry a shot. Unfortunately, I have no good excuse for this. (Fair warning: I’ve been collecting links and ideas on this topic for several weeks now, and even though I intend to break up the post into more manageable chunks, I have a feeling this is going to be a doozy) …
