Re: ATmega328 unavailability due to global semiconductor crisis
Hans, you are so honest and as someone else said - transparent - about it all, you are to be commended. Besides we all know you. You'll figure out something regardless. Maybe some people will be miffed by your price increase but if they are upset, let them be upset. Nothing in this world is the same as it used to be. I think we are blessed to have what we have. Keep up the splendid work sir. You are truly an inspiration.?

Re: ATmega328 unavailability due to global semiconductor crisis
Hans has already said that he's using the STM32 family for some of his projects. However, I fear that almost any ?C is going to be in short supply for some time. Jack, W8TEE

Re: ATmega328 unavailability due to global semiconductor crisis
¿ªÔÆÌåÓýIf there is a change like that, I would also suggest a minor change ? On the LPF / BPF alter the pin outs so that the two signal pins are the 2 central pins and the ground pins are the two outer ping, their circuits are the same from both directions, it then makes it no longer required to put them in then right way round on the board, and eliminating a potential problem ? Down side you have to have an old an new PCB for the kits ? Peter M0PWX ? ? From: Mark M Or perhaps this would be a good time to move on from the 328?

Re: QRP Labs Shack Clock
Adafruit has a nice selection of 20x4 (and 16x2) displays.? Some with reverse/negative(?) LCD which can help with viewability in some lighting conditions.? They also have ones with RGB backlighting if you want to have some fun. ? They all take the same 16 pin header except for the RGB which has a few more pins that you would need to separate and send to your own RGB circuit.
They also sell the temp sensors that work with the clock (it can display 2 different temps) If you plan to go portable with it like I am, they also make a 3.7 -> 5.2V voltage converter + battery charger that will let it run off a typical rechargeable LiPo type battery or USB power. I am building a self contained field clock for portable operation. It will show UTC + local date/time, my gridsquare, altitude and coordinates, local temp and maybe the temp inside my go box(why not?). I'll post pics when it's done and running (it's a winter project). |

Re: Soldering TCXO module on QDX
The TCXO board is very small so not very heat tolerant, so avoid excessive heating. Normal care in soldering. ? I have found that using the longest cut off leads you have, leaving excess on both ends and not trimming until both sides are soldered appears to work better.? This will help in preventing the main board connection from coming loose while soldering the TCXO board.?
