KiCon 2019 Call for Talk Proposals

KiCon2019

KiCon, a conference focused on KiCad, is happening April 2019 in Chicago and the call for talk proposals is open:

KiCon 2019 Call for Talk Proposals

KiCon 2019 is a conference for people who use and love KiCad. This is the first year of KiCon, but hopefully the first of many! It will take place April 2019 in Chicago IL, USA.

We are looking for community members to propose talks, which will be recorded and uploaded for the rest of the world to utilize. We’re looking for stories about tools, methods, and successes using KiCad in manufacturing, research and business. This conference will bring together the power users of the tool to talk about how they use KiCad on a regular basis and to share that knowledge with others.

Laptop Keyboard Conversion to USB

From Frank Adams on Hackster.io:

I made a “nearly universal” USB controller using a Teensy LC or 3.2 on an FPC connector board that will work with most laptop keyboards.

I did this project because I’ve seen many forum posts from people asking how to use the keyboard from their old broken laptop. Unfortunately the answers given are “it can’t be done,” “it’s too hard,” or “rip apart another USB keyboard and steal the controller circuit.” I believe I have a better answer by using a “nearly universal” keyboard controller based on a Teensy LC or 3.2 mounted on an FPC connector board. This board accepts keyboard cables with up to 34 pins on a 1 mm or 0.8 mm pitch. The board shown below won’t work on every keyboard but it will work on most.

Keep Both Hands on the Probes With This Oscilloscope Footswitch

We’ve got two hands, so it’s natural to want to use both of them while diagnosing a circuit with an oscilloscope. Trouble is, keeping both hands on the probes makes it a touch difficult to manipulate the scope. If only there were some way to put your idle lower appendages to work.

This multipurpose oscilloscope footswitch interface makes so much sense that we wonder why such a thing isn’t standard equipment on more scopes. [Paul Roukema]’s interface relies on the USB Test and Measurement Class (USBTMC) protocol that allows most modern scopes to be remotely controlled, somewhat like the General Purpose Interface Bus (GPIB) protocol of old. [Paul]’s interface uses an STM32 microcontroller to talk USBTMC to either Keysight’s Infinium scopes or the Tektronix DPO line, since those were what he had to test against. Tapping the footswitch cycles the acquisition mode on and off or triggers a single acquisition. He’s thoughtfully included the USBTMC specs in his GitHub project, so adapting it to other scopes should be straightforward. We’d even wager that older scopes with GPIB could enjoy the same handsfree control.

Building Portable Linux Devices: Never Been Easier, But Still Hard — Hackaday

We live in a Golden Age of single-board computers. There was a time when a portable computer that was any good was a relatively rare and expensive device, certainly not something you could expect to replicate for yourself. A Psion, or later a Palm or perhaps a WinCE device would have been a lot more…
