A few weeks ago Kolja Windeler’s Queso DIP was featured in a blog post. Queso connects to C.H.I.P. and adds four additional USB ports, plus handles power.
But Queso is not the only DIP JKW, as he’s known on the forums, is working on. He currently has five more DIPs in development! Make sure to use the forums and let JKW know if you have questions about his awesome new DIPs!
DIPs are add-on boards for C.H.I.P. that connect directly to it and expand its functionality. A good DIP design doesn’t add every possible feature all in one board, but focuses on adding one or two new features. That’s why there are so many different DIPs starting to appear on the forums –each DIP is meant to specialize.
Salsa DIP brings realtime control to C.H.I.P., which is great for controlling motors and blinking lights. The awesome four-wheel drive vehicle in the video below is powered by C.H.I.P. and Salsa DIP.
Onion DIP has a built-in relay, which is great for controlling external devices and it also includes a small prototyping area for wiring up your own custom circuit. It’s a bit like the Relay DIP that Gus created for my RocketC.H.I.P. project.
(Thanks to iot_steve from the forums for pointing out that the Onion DIP does have a realtime clock.)
Spinach DIP is filled with 32 powerful, multicolored LEDs that are controllable directly from C.H.I.P.. The video below shows a C.H.I.P. and Spinach DIP in action, but it’s extremely bright and difficult to see the boards. Scroll to the top of the page for a more clear image of the Spinach DIP.
Guacamole DIP is still in the works, but it’s designed to take a digital audio source and convert the output to an analog signal. From the listener’s perspective, the analog signal is a much more rich, full sound compared to the digital signal.
This conversion is actually done by a specialized component known as a digital-to-analog converter or DAC for short. If you’re interested in a more detailed explanation of how a DAC works, check out this site.
Not in WiFi range? No problem. The Hummus DIP provides a wired ethernet connector for C.H.I.P.. Believe it or not, there are actually some projects where having a wired ethernet connection, not WiFi, is a must.
A good example are DIY cluster computers, where multiple boards are wired together to cooperatively perform computational tasks at very high speeds. Since each board needs to quickly communicate with the others, wired connections are the preferred data transport method.
These DIPs are all community created, so you won’t find them anywhere but the forums. Thanks to their open source hardware design, the files and tools are available for you to make your own.
