With several Hams in Holland we have Build the LC Meter MOst components are no problems. Only the Entry Jacks are not available with stores in Holland. So we did make a minor modification so we can use more common Jacks See our solution in the attachments.. -- With Regards Cor Struyk, PA0GTB

I thought I would share some pictures my latest build for the NTP Clock. This is my second build, I wanted to try out Bruce's 3d printed case https://www.thingiverse.com/thing:5372775. I printed the case on an 'original' Ender 3 printer. I bought the printer in late 2019 and have made a few hundred prints using it. (I now have a small printer 'garden', 6 printers, 4 Enders and 2 Anets.) Of all my printers, the original Ender 3 gives consistently the best results. I mounted a usb c female connector in one of the existing holes on the side of the case. I used some brass standoffs of the right height and the universal builder equipment and material, a hot glue gun. I connected the usb c female to a usb micro male which plugs into the ESP8266 module. I also used a dab of hot glue to give some strain relief where the wires are soldered to the usb connectors. Here is the finished side view of the connector. Notice how smooth the side is, the small blemishes at the join line are from slips with the hot glue gun. Here is the front of the finished clock, taken with no flash, so it looks much dimmer than it really is. The tft and pcb were hot glued to the front of the case. Even though I have made 300-400 prints, what I have determined is that 3d printing is as much of an art as it is a science. I just recently discovered/developed a technique which results in really good results for me. My technique is super simple, too! If Bruce gives me the ok, I will make a post with pictures showing my technique, since it is somewhat off topic. Below is a picture of the back of the clock showing how smooth the finish is. The back was the side on the surface of the 3d print bed. If you are 3d printing, you will appreciate how smooth and blemish free the surface is. (I couldn't avoid the flash reflection.) You can see the overall smoothness of the sides in the pictures above. A big *THANKS* to Bruce for sharing his designs, and special thanks for the box design. Putting a build into a nice enclosure has been my building nemesis for decades! Good building! Of course, if you 3d print, YMMV! Mitch W4OA Opelika, AL

A friend admired my NTP Clock (dual) on my qrz.com web page. I volunteered to furnish him the pcb and I 3d printed him Bruce's nice box. The box came out GREAT! Since I had some ESP8266 modules extra I decided to program one for him, I would assign an arbitrary wifi name and password so he could check it out with his cell phone hotspot. I programmed an extra ESP8266 module and plugged it in, compiled for my home wifi. Compiled just fine, no errors. But no display, no joy. Compiled and uploaded Bruce's "Hello World" display test sketch, compiled and uploaded ok, led blinking away. But, no display. Checked the TFT_eSPI library by Bodmer, it is now at version 2.4.72. I was at 2.3.59. Bruce used 2.2.14. I tried to retrogress the library to 2.2.14, no joy, it won't load any version prior to 2.3.59. Unfortunately, the last time I compiled the clock was when I built mine, over a year ago. I don't know how my library got updated, but it did. So I am stuck! Anyone run into this problem and find a workaround, or any suggestions on how to solve my problem? Tnx in advance for any assistance! Mitch W4OA Opelika, AL
