What's Been Happening?Since the last website update a few months ago which coincided with the publication of one of my designs in
the March 2015 issue of the US amateur radio magazine "QST", published by ARRL, I've continued to design and build new items.
This time around, the NEW designs I've added to the website include:
A suite of three different designs for temperature controlled soldering stations, with a detailed design for the most compact unit. It uses a single 8-pin ATtiny25 microcontroller and not much else, and it is packaged in a compact 3D-printed enclosure, also of my own design. (Right-click the image for a closer look or visit the web page)
That's something you'll be seeing more of on this site - cases designed and built using my 3D printer. I purchased a Printrbot Simple Metal 3D printer late last year, and since then, I've been making all sorts of things with it.
Another new addition to my website is a Four Dot Clock using just four cheap LEDs to display the time. It's surprisingly accurate. More interestingly, perhaps, is the fact that unlike most clock designs you might have seen, this one does not require another chip to actually do the timekeeping. The clock's ATtiny45 does all that, and more.
And the final addition in this website update is an accessory for the temperature controlled soldering iron I mentioned earlier. It's a tip cleaner accessory using an easy to obtain item from the supermarket, and printed on a 3D printer.
And, of course, all of the other designs are still available to browse and build, all listed over to the left in the index. help yourself!
What else is on this website?
Aside from my rants about Yahoo and mail, my website describes a variety of projects related to my hobbies of amateur radio and electronics. These include circuit diagrams, descriptions of how they work and what they do, PCB layouts (sometimes), construction details, and software for designs which use microprocessors or microcontrollers.
For the record, the microprocessor designs here use the AVR chips including the ATtiny15, ATtiny25, ATtiny45 and ATtiny85, ATtiny2313, ATtiny26, ATmega8, as well as some earlier designs which use 8051 processors including the 80C552, 80C751, 80C51, 80C52, AT89C1051, AT89C2051, and AT89C4051, and so on. Almost all of my 8051 software is written in assembler while the AVR code is a mix of assembler and BASCOM (Basic).
New Designs Coming Soon...
New projects and designs to be added soon (I hope):
- Some notes about adding a crystal oscillator to my QST talking counter design
- Homebrewed battery holders (Try to buy a battery holder in the desert!)
- Adding a speedometer to a car - Yes, I know, that sounds really strange, but wait...You'll see why this was necessary
- My version of an LC meter, and
- A new take on the SWR meter
See you soon...
