Hackaday Prize Entry: ESP Swiss Knife

The best equipment won’t help you if you don’t have it with you in the moment you need it. Knowledge, experience, and a thick skin may help you out there in the mud of the hardware battlegrounds, but they can’t replace a multimeter, an oscilloscope, a logic analyzer, a serial console or a WiFi access point. [Arcadia Labs] has taken on the challenge of combining most of these functions into a single device, developing the Hacker’s equivalent of a Swiss Army Knife: The ESP Swiss Knife.

esp_swiss_knife_enclosureJust like a Swiss Army Knife is first and foremost a knife, the EPS Swiss Knife is first and foremost an ESP8266. That means it is already a great platform for any kind of project, and [Arcadia Labs] supercharged the plain ESP-12E module by adding a couple of useful features commonly used in many projects. There’s an OLED display, four pushbuttons, a temperature sensor, and a Li-Ion cell with a charging module to power the device on the go. A universal “utility socket” breaks out the ESP8266’s leftover GPIOs and the supply voltage for attaching further peripherals.

With the hardware up and running, [Arcadia Labs] went on with building a couple of applications to provide the functionality that would make the device earn its name. Among them is a basic oscilloscope, a digital NTP based clock, a thermometer, a WiFi tester, a weather station and a 3D printer status monitor. More applications are planned, such as a chronometer, a timer, a DSLR intervalometer and more. A protective 3D printable enclosure is also in the works. [Arcadia Labs] has been joining the Hackaday Prize 2014 and 2015 before and we’re glad to see another great build coming into existence!

  1. The hardware is quite similar to the Project I’m currently working on (well, actually I’m waiting for my PCBs :)).

    I use a TPS63031 buck-boost to get all the charge out of the battery and an MCP73871 to charge the battery. I couldn’t find what this project uses as charging regulator as there is no information on the .io project site. I also added a microSD socket and 4 buttons for UI navigation which has left no spare pin to break out.
    The form factor is also quite a bit smaller (probably mostly because I didn’t use perfboard). Check out the PCBs here: https://oshpark.com/shared_projects/2DB07IAN
