And a shout out to Tim Keller. He re-wrote my bad RP2040 PIO code for Apple II keyboard emulation. With the new latching circuit, I can type my full speed! So fun! twitch.tv/videos/1457172…

My little side project which i worked on between everdrive stuff. WSPR beacon with menu, GPS navigation and time synchronization, up to 3W TX power, can work from regular USB power bank. Made of junk from nearby Amazon sotcks, operational range - the whole world (:

9+ hours from home on a work-cation. Decide to hit a Renaissance faire and by sheer coincidence run into POPESQUIDWARD emily💅🏼 and Ozzy. Nice to finally see you all in person!

Woodworking experts, what else does this skill tree need? Color in the boxes, see your progress and get inspired to try new things. Basic, intermediate and advanced skill ideas needed.

Like many new indie games, Olliefrog Toad Skater has been stuck with a case of O.H.P.M.: Obligatory Hipster Photography Mechanic. Symptoms include additional backburner Jira tickets for expensive post-processing filters & at least one snarky Slack comment about bokeh. #gamedev

With a lot of find-and-replace I converted the C code for my dsPIC33E video chip into C# so I could attach it to my Z80 emulator. I need to design a way to transfer sound commands to the chip and read pixel data back (e.g. for POINT) so easier to prototype here!

#KORG is legendary for their synthesizers, but what's the deal with the #oscilloscope kit they released? On #WorkbenchWednesdays, James finds out, as he builds and tests out the NTS-2 kit! bit.ly/3QhEyr8

Soon. You’ll get to see a project video that took over two years to make. (And many of you helped with!) Until then, what project have you had major ups and downs on, like this? youtube.com/shorts/0ybzwxC…

Two Raspberry Pi RP2040s help modernize the (almost) 40-year-old Apple Mega-II chip. One adds a USB Keyboard and another does VGA Output on this IIe-compatible computer. See the video, design files, and code on the @e14Community: bald.ee/e14-megaiie

Another component of my Train Simulator physical #train controller: dimming the backlight of my air gauge from the dashboard of a (virtual) Class 801. #diy #simulator #ee

In my ongoing quest to build a physical controller for Train Simulator, I'm building a module to fully control real UK train speedometers, including the ATP LEDs and alphanumeric status display. #trainsimulation Train Simulator #uktrain #simulation

Huge props to Tim Keller for helping me turn my cardboard prototype into a spiffy set of laser-cut UK Class 80x-style door controls for #TrainSimulator. Train Simulator #trains

Time for more buttons and switches in my #Train #Simulator controller setup, which can only mean starting up my assembly line and making more of my CAN bus controller boards (z80.me/blog/can-contr…). #ee Train Simulator
