Welcome! We are enthusiasts interested in Arduinos, Raspberry Pis, and other little computer boards that are friendly for beginners. CARPE is a great place for beginners to start.
CARPE is a group of people who love to play around with hardware. From automated chicken coops to robot safe cracking to thermal imaging, we love it all. Join us to tinker, learn, hang out and have a good time.
The location has MOVED! to
"The NEW Columbus Forge"
with free valet parking.
June Meeting 2019-06-11 Meetup page
This month Rob Huston will continue our series on signal amplification with:
Adventures in Multi-Stage Amplifiers:
A brief tour in multi-stage BJT amplifier circuit design, culminating in the implementation of a simple push-pull amplifier to drive an external speaker from the headphone jack of a MacBook Pro computer.
All are welcome, especially beginners.
There is a technical mailing list for technical discussions. It is separate from the meetup mailing list. To get good answers, consider following the advice in the links below.
Pillar Technology has a facility called "The Columbus Forge" on the eighth and ninth floors of the Lincoln Building. The meeting will be on the ninth floor. The Lincoln Building is at 711 North High Street. The Lincoln Building is the second building south of Buttles.
Free valet parking:
Pull over in front of the Lincoln Building at 711 North High Street. Save the ticket the valet gives you when you hand your car over to the valet. Go to the ninth floor of the Lincoln Building and enter The Columbus Forge at the glass doors that you can see from the ninth floor lobby. Be sure to get a validation sticker from one of Pillar's experience folks to make the valet parking free.

The ESP Series of Systems on a Chip for Prototyping IoT devices
Bill Ball will give an overview and bring examples of the ESP series of SoCs by Espressif mounted on development boards. Implementations of the ESP32 & ESP8266 offer the means to quickly learn and prototype connected hardware at low cost using a variety of programming environments, languages, and attached peripherals. Bill's current focus is on evaluating the Lolin D32 Pro implementation of the ESP32 as the basis for learning micro-controllers in a rapid prototyping class.
Bill is a Scholar in Residence at Capital University where he teaches courses on rapid prototyping and game and VR development. He also leads the planning of the annual MakerX festival of creating with technology.
April Meeting 2019-04-09 Meetup page
One of the key skills needed when working with hardware is the ability create good conductive connections between components, which usually means skillfully melting metal for that purpose. Are you good at soldering? Bad at soldering? Never soldered but dream every night about doing so? Well then this is the group for you. We will be having our quarterly soldering workshop to improve soldering skills, make some simple gadgets and hand out.
If you have a soldering iron and tools, please bring them. If you have anything you would like to solder or un-solder, please bring those.

First Software for New Hardware by Jim Prior
This presentation shows an example of getting software to work on new (as in "never existed anywhere before") hardware. It gives one a feel for how this kind of software development goes. Getting the first sofware to work on new hardware can be difficult. One does not know if the hardware works or not and one needs software to test the hardware, but one does not know if the software works or not either. Both software and hardware must be correct for either to work. So first software is debugging not just software or just hardware, but both simultaneously. If the desired output does not happen, it can be very difficult to figure out what is wrong. One learns to start with the very, very, very simple and progress to the complex in tiny incremental steps. KISS applies for embedded software much more than with regular software.
