I have, for quite a while, provided modified versions of the code for my projects free of charge. However, the cost of webhosting for this site has tripled in the last couple of years and the little I make out of the pcbs I sell goes nowhere near covering this cost.
As of October 2017, I will be asking for a donation in exchange for providing custom modified code for my projects to help keep this site available.
Updated Australian Band Plan page with the latest info (under 'Misc' heading).
A modification plus software to allow the Simple DDS VFO to be re-calibrated as often as you want without having to re-program the PIC has been added to the Simple DDS VFO page. Simple DDS VFO bug problem fixed. Code uploaded to webpage as version 'c'.
There is a bug in the Simple DDS VFO code. See Simple DDS VFO page for the problem and updated code. Included an add-on for the Simple VFO project to indicate which step size has been selected. Simple DDS VFO project updated and software file uploaded. The pushbutton on the encoder is used to change step size (step sizes 10Hz, 1kHz and 10kHz).
Noise Canceller kits now available.
Updated both the DDS Xtal Substitute and DDS Xtal Substitute Mark 2 projects into one project. The original webpages are available to download as PDF's.
New project added - my version of the X-Phase noise canceller. PCB available and a kit of parts to follow soon
It is not the policy of this website to endorse products or companies. However, I will make this one exception. Several months ago a new HP Laptop was purchased and everything was fine until we tried to hook it up to the TV via it's HDMI connection. After spending many hours with HP support over a couple of days, it still wouldn't work, so I decided to call it quits and return it for a refund as obviously faulty (I should point out that HP support had been extremely helpful and bent over backwards in an attempt to fix the problem up to this point). On the third day, out of the blue, I received a call from HP asking if I had organised the refund yet. When I told them I hadn't, they told me they would send a technician out to fix it. Now some will know I live in the middle of nowhere (which I explained to the person on the phone), but they said that didn't matter. To get to the point, the technician arrived a couple of days later, replaced the motherboard in the laptop and it is now working as it should. All I can say is, to me, that is service above and beyond what I would consider reasonable in the circumstances so thankyou HP. Other companies would do well to take a leaf out of their book in regards to product support. (I have no financial interest in, nor received any other benefit, financial or otherwise for the above comment, from HP or any other source)
I'm fiddling with the website again, mainly playing about with this page, but will also be adding the Model Railway page either later this month or early in the new year. I'm also trying to work out why the address bar gives multiple slashes when moving between various pages, so if you get a 404 error or some other strange happenings occasionally when visiting, I'm probably playing with various code changes at the time.
Hopefully, I have cured the multiple slash problem in the browser url bar now
I've been a little slack updating this page, but have been updating/adding some of the projects and other pages. Particularly the Xtal Substitute and Simple VFO projects. The Noise Canceller project has also been added. I have, for quite a while, provided modified versions of the code for my projects free of charge. However, the cost of webhosting for this site has tripled in the last couple of years and the little I make out of the pcbs I sell goes nowhere near covering this cost. The rest of the cost is paid from my own pocket and so far I have resisted the temptation of adding horrible, intrusive, in your face advertising to my pages, although that may have to change if push comes to shove. So, as of October 2017, I will be asking for a donation in exchange for providing custom modified code for my projects to help keep this site available. I've also been asked why no Paypal button for the pcb's and kits. Simple answer, besides the extra cost of having to get an SSL certificate, - too many dickheads who have nothing better to do than trying to hack websites and I've got better things to do than filter their crap. I do accept Paypal, but you need to contact me for the details. As an aside, I recently received from the UK, a proper, old school, written on paper and posted order for a pcb. It was a distinct pleasure to receive (considering about the only things that turn up in the mail these days are bills and junk mail).
TIP - need pcb pins or sockets to connect to pcb pins? Find an old lead with DB style connectors that you no longer have use for and carefully remove the pins.
As a lot of people have pics of things unrelated to ham radio on their websites, I thought I would add a couple of my own. Banjo, our Red Heeler/Koolie cross at 4 months old. And at 12 months old (Feb 2016) enjoying his birthday breakfast treat of banana on toast.
A new addition to the family, an 11 week old kitten (end July 2017), rescued by Banjo after being trapped between a water tank and fence. Her name is Storm after her colouring and she's eating a bit of toast and jam (yes, our animals do eat strange things, including lemon meringue pie). They are now the best of friends.
Banjo hasn't got any bigger than he was at 12 months old and although Storm has, she is going to be a miniature cat. When I can get her to sit still long enough, I will try and get a pic with some sort of reference to show how small she is compared to other cats of the same age (she weighed 2.5kg when we took her to the vet to be spayed mid Nov 2017). In the meantime, above is a pic of the pair of them together under the ceiling fan (it was a stinking hot day).
