Re: How about an ultra-portable "QCX mini" version? #qcx

We're probably about the same age (I've been licensed since 1954) and suffer the same issues when building anything any more. Still, I've learned to enjoy SMD parts and find them probably a little easier to use. Videos like yours need to be more widely distributed so people can see how easy it really is to use SMD components.
As to Hans and the QCX, he doesn't use the Arduino Nano. Instead, he uses the "raw" Atmel 328 chip, thus avoiding the resources sucked up by the bootloader. That's why you have to use something like Arvdude to program a fresh chip or upload a new version of the software. Last time I spoke with Hans, he has something like 9 bytes left. I've done a fair amount of programming myself, but what he's packed into those 32Kb's is nothing short of amazing. He is well aware of the limitations of the 328, and the QSX will house an STM32F4 series chip which has a lot more resources and a faster clock. Like everyone else, I can't wait to get my hands on it. (Right now I'm talking to my QCX via CAT using a Teensy T4...I have some serious plans for it!) If you want to dink around with the code, I know of a beginning C book I can recommend...
There would be some advantages to having a "semi-kit" like the µBITX, as some of the support questions Hans has to field would likely disappear. I can see pro and con for each approach. We'll see what happens. Anyway, good work on the video!

When I was almost 59 I decided that it was time to learn to solder SMD's. It made perfect sense to wait that long. I can't see as well as I used to. My hands aren't as steady. But! I am grandkid trained. I have lots more patience (cough). I stopped aging when I turned 6D. I am now 6D2. The alphabet age is wonderful :)
