I recently put together one of the very cheap ($15) toy digital oscilloscope products from JYE Tech, the DSO150, see https://jyetech.com/dso-150-shell-oscilloscope/ The main board comes fully

Bruce: Looks Great. Please put me on the list of folks for more details, when they are available. Thanks 73 Fred WD9HNU

Hi Bruce, Nice job, I have done the opposite, no custom pcb, modules including a TDA530 amplifier module joined using crimped KF2510 connectors. All are powered from an external 5V mobile phone power

Hello Bruce W8BH, That looks really good! How do the PCBs arrive? Are all three boards stuck together? You are using JLCPCB? What are the parts used? What is the most difficult SMD to solder on this

Nice job Bruce. Can't wait to see more details. 73 Ken WB2ART

Attached are photos of a Morse Tutor prototype I built. Some features: Handheld: 110 x 60 x 20 mm (roughly) Li-poly battery or USB powered, with built-in battery charger Larger 3.2" display. Built-in

Hi Mark: I really like your case. The idea to make it as thin as possible is a great approach. My only issue with it is permanently soldering The STM32 to the PCB. I guess the reason that is an issue

John I did a derivative work of the stl you references and they are at https://www.thingiverse.com/thing:4190589 the main difference is that it is a little thinner since I soldered the stm to the

I hope this message finds everyone well. ?Very difficult times for sure. I saw the idea about creating “sub-groups” for kitting the W8BH Morse Code Tutor. ?I would like to do whatever I can to

Hello Bob. Yes it would help if you uploaded your notes. Ken,? I had the ST-Link files.? What I am after is how others are programming the Blue Pill using a Windows machine.? I am not a Linux user

Hello Bob GM4CID, Go ahead and upload your notes to the File section. Let me know how it goes. You will be the first person to try, as far as I know. I recommend uploading your notes to GitHub or a

I initially loaded the sketch using the Arduino IDE and a USB to TTL serial adapter connected to A9 and A10. Later installed the bootloader onto the STM32 Blue Pill and now can install sketches in the

Hello Jim, The link to the STLINK utilities is at: https://github.com/texane/stlink Just in case that link does not make it through to you, here it is, broken down: http colon double forward slash

Hello Bob GM4CID, I appreciate your effort to try and stimulate some discussion. I think that the lack of an actual "KIT" for the W8BH Morse Tutor might be part of the reason for the lack of

Has anyone done the Blue Pill programming using Windows that has written up the procedures?? I was trying to find the binaries as the group home page /g/w8bhMorseTutor and going to

Hi Ken, hope you are coping with current personal restrictions. Well I with this approach I can get a new concept up and running quite quickly with a known starting point and fewer problems from

Hello Bob GM4CID, That is a very sharp looking Morse Tutor! Your Single Lever Paddle is also a nice piece of work. Ken KM4NFQ

Hello Bob GM4CID, Wow! That is a very nice prototyping setup you have made. I use Busboard Prototype Systems BB830 Solderless Plug-in Breadboards. https://busboard.com/breadboards In the past, I have

Here is an example of my latest approach to prototyping, a POC (proff of concept) breadboard with an Arduino Nano in an expansion board prewired to an I"C 16x2 LCD, a rotary encoder that can be

Here is short video of my STM32 W8BH Morse Tutor build using point to point wiring, unit is powered by a 5V mobile phone powerbank, speaker is recycled from a broken TomTom satnav. The initial build
