Re: Morse Keyboard Photos
Hello Ken, ? Yes I¡¯ve made contacts with the 20 meter QCX unit, but in all honesty it was while I was using a straight key (J-38) a while ago and not the Keyboard Keyer that is currently attached.? My longwire antenna here at the house broke a while ago during a storm and I have not repaired it yet. However, I did hook up a line to the house gutter which if I use the tuner in line should be just fine for the system that you see in the photo. I¡¯m planning on getting it up and running sometime this weekend and hope to be able to report on it and the keyboard keyer next week. ? The keyboard keyer box is one that I got from ¡°The Container Store¡± up in Kenwood, Ohio (a northern suburb across the Ohio River).? Only trouble with it was that it was a little delicate, one of the hinges broke the second time I opened the box.? I replaced the hinge pin with a short piece of brazing rod (the gold color of the right hinge in the picture). ?This was the time I decided to try a store bought box and I have had second thoughts about that after the hinge experience.? Just wanted something to keep the dust and grime out of the PC board material. ? All for now, 73, Allan,? WA9IRS ? Sent from for Windows ?

Re: new project: LED tester
Greetings, I have built the LED Tester project on a breadboard, following the tutorial that Bruce wrote. I used a 400 tie-point Solderless Plug-in BreadBoard with power rails from Busboard Prototype Systems (BB400).
My Build Notes can be found at Bruce's GitHub site:
Bruce's tutorial will take you step-by-step from Blink on the SeeedStudio XIAO MCU to a working LED Tester. Following the tutorial will allow you to check all the main components (MCU. OLED, Digipot, & Rotary Encoder). I discovered that the reason my LED Tester did not work properly was due to a very small whisker of solder bridging the SPI pins on the MCU. Si I highly recommend breadboarding the project first, before soldering a PCB.

LED Tester on a Breadboard Build Notes
#build
Greetings,
I recently built the LED Tester on a breadboard.
As I built the circuit, I drew a few diagrams.
The diagrams are organized in an HTML page that can be viewed with a web browser.
Bruce W8BH, put my notes up at his GitHub account:
The latest documentation for the W8BH LED tester is now available.
This is a fun project that results in a very useful piece of test equipment.
A while back I bought a few Grab Bags of LEDs without any documentation.
Also, this will be a helpful tool for figuring out what all those loose LEDs in the junk box are.
Hopefully helpful.

Bruce,
Thanks for the keyer design, on my future list of projects to be sure!
As a note, a while back I experimented with several USB shields for Arduino like??and?
The first pretty much worked out of the box and I seem to remember that I got the second one working t0o. They both have some sample keyboard reading software. Proved that to my satisfaction that it basically worked, but didn't stress test it at all.
I used it with a mini wireless keyboard:
Just a thought if anybody wants to take your design and add USB (wired or wireless) connection to your keyboard design. Definitely more expensive than your solution, but the wireless mini keyboard has interesting possibilities for SOTA, etc.

Ah, that 'splains it. No problem...keep us posted when/if you decide to release it.
And if you need a beta tester, let me know.? :)

Re: new project: LED tester
Greetings,
Thank you Bruce W8BH for sharing your LED Tester project with us.
I know that I, for one, am very interested in building this project. My current LED tester consists of: a bench power supply, two DMMs; one to measure Voltage, and the other to measure Current, a Resistor Substitution Box, a breadboard where it is all connected together and where I insert the LED.
It works great, but it is rather large. 8^D

Hi Mark.
You are correct.? I did not publish the code for the YouTube version.? ?It is incomplete.

Hi Bruce...
The code you link to does not seem to match the clock in the YouTube video. The three screens are there but the touch zones seem to be different and there's no audio code and no speaker or moon icons. I'm using the GPS_CLOCK_triple code. Is that the latest source?

The following breakout board is not nearly as clever as Ken's design, but it's what I used when breadboarding the keyboard keyer.

Re: New Project: keyboard keyer
Greetings,
Thank you Bruce W8BH, for sharing such a fun project with the World..
I recently built the Keyboard Keyer on a breadboard. To do so, I needed to breadboard the PS/2 port. My solution was to use some stripboard to make a BreakOut Board (BOB). This is the diagram of the BOB I made:
This is what the actual breakout board looks like after soldering it together.
I superglued the FR4 sides of the stripboard together, lining up the holes. For vias, I used pieces of resistor wire, bent in a U shape. I soldered the free ends of the U first, then soldered the U side, then clipped off the U. The support tabs on the PS/2 port hang over the edge and do not need to be soldered.
I was able to plug the BOB into the breadboard, then add the voltage divider resistors to the breadboard.
I soldered male headers on the OLED, so it fit on the breadboard. Likewise for the XIAO.
Here is a short video clip of Step 3b of the Keyboard Keyer tutorial:
My eyes are not what they used to be, so I drew diagrams for the XIAO, OLED, and the Piezo.
Finally, here is a snapshot of the completed breadboard with the final KeyboardKeyer sketch uploaded.
It works as advertised.
This is a fun project to breadboard.

Mine, too.? Thankfully the biggest chip in my project only has 48 pins.? And it has real leads.

those 100+ pin ICs are a bit beyond my skill level. :)

Ooops...never mind. I neglected to update the user_setup.h file.
Sorry about that...I've been immersed in the ?SDX world for a while and away from clocks. I hadn'd seen this version and it looks pretty spiffy. I'll probably not do it SMD, tho...those 100+ pin ICs are a bit beyond my skill level. :)
Thanks for another cool project.
