Openbench Logic Sniffer is an open source logic analyzer. It’s designed to support the SUMP logic analyzer software at the lowest possible cost. Download the source and design files from the Gadget Factory project page.
This project started in the comments on a post. Initial circuit design, PCB layout, development, and testing continued in the forum under the code name Project SUMP PUMP. Many, many people contributed ideas and advice, the Gadget Factory and Dangerous Prototypes coordinated circuit development and routed the PCB. We borrowed heavily from the Gadget Factory’s Butterfly Platform.
The Open Logic Sniffer is a purpose-built logic analyzer board designed to be low cost but high speed. It sacrifices a lot of the features you’d look for in a full-scale development board to achieve our primary goals:
* 70MHz+ sample speeds * 32 channels * 16 buffered, 5volt tolerant channels * USB interface, USB powered * USB upgradable everything * Make it as DIY as possible * Make it as open source as possible * $30-$40 price range
We didn’t quite hit our initial price range, but we got really close.
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
