How do you breadboard your Arduino projects, here is how I currently do mine.
|
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 switched to A0/A1 or D2/D3 or disconnected, an encoder switch to A2 and another switch to A3. All wiring is done from underneath so all the Nano ports and multiple Vcc and Gnd connection pins are accessible.
In the photo an OLED display and a Si5351 DDS on the small breadboard are connected using I2C. A second Nano and rotary encoder are for the moment mounted on the larger breadboard. and connect to an adjacent SPI TFT display. When not powered from a PC, I use either a 5V mobile phone power bank and a USB lead or a couple of 18650 batteries to Vin. How do you do your prototyping? 73, Bob GM4CID |

Wow! That is a very nice prototyping setup you have made. I use Busboard Prototype Systems BB830 Solderless Plug-in Breadboards. In the past, I have purchased cheap Chinese breadboards from Amazon and eBay. However, the cheap breadboards are not very cheap in the long run, as the quality is very poor. So I recommend buying good quality breadboards for prototyping. I made a simple setup to hold some potentiometers, but otherwise my parts are usually scattered around the breadboard.

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 discussion? However, the lack of an actual W8BH Morse Tutor Kit gives everyone an opportunity to kit the project in their local area, according to their local needs. Some areas might have ten people, and other areas might have fifty? Instead of getting an 'extra' PCB from someone who has purchased a set of five boards, each person here might order a set of five boards, and build a couple of units to show to their local Amateur Radio Club or Society. There is the opportunity to be an 'Elmer' and to share a project that has the possibility to allow beginners to: (1) learn how to solder, (2) how to use the Arduino IDE, and (3) learn CW. I don't know about the UK, but here in the USA, the requirements for CW have been totally abolished. As the current population of CW Operators become Silent Keys, there are not enough replacements to further the practice of CW. It will slowly become a thing of the past, as fewer and fewer people practice the discipline. So I encourage everyone to order some PCBs, build a couple of W8BH Morse Tutors, and try to drum up some interest for CW in their local area. The potential for exciting some interest in homebrewing and CW is there. It just requires some 'Elmers' to get the ball rolling. Young people are the future of Amateur Radio. That includes the 'young-at-heart' as well as the actual youth. The QRP Labs 'QCX' 5W CW Transceiver was designed for the Youngers On The Air (YOTA) summer camp in 2017. So if a local group can be stimulated to build a Morse Tutor, and learn CW, then the next step would be to lead that group in the building of a QCX, or maybe a W8DIZ 5-Watter CW Transceiver. Yeah, it takes some time and effort on the part of the person who decides to be an 'Elmer'. But the 'self-isolation' period for the COVID-19 virus won't last forever. Now is the time to 'kit' a W8BH Morse Tutor. When groups can once again get together, working units can be shared with others. This group was started to discuss using the W8BH Morse Tutor, help troubleshooting builds, and sharing the joys of learning CW. Ken, KM4NFQ On Fri, Mar 27, 2020 at 1:51 PM GM4CID <gm4cid@...> wrote:
