Since I changed my other sites, I may as well complete the trilogy. Ka-Ching Pal now has the same snazzy look as my other Silicon Sparrow branded sites.

I liked the new Super Transcribe site that Bea designed for me so much, I copied the design to Serial Gadget too! It has the Silicon Sparrow logo at the top and a more prominent BUY button. The colour scheme is much improved and it ties in well with my current branding exercise.
It looks like [...]

Bea did a neat new design for me. This is a lot better than the previous design.
I like the more prominent DOWNLOAD and BUY buttons, plus the news items are better separated from the main text. The Silicon Sparrow logo has been included in a big way which continues on the theme of drawing all [...]

I was setting up some eCommerce websites recently, maybe it was a combination of not enough sleep and too much coffee but I thought to myself, I wish that whenever I got a payment through PayPal, my PC would make a Ka-ching! noise.
So then I spent a couple of hours making a Windows Tray App [...]

I’ve just built the first of my new revision 3 RS232 Bit Rate Converter. It has the following improvements:

Cleaner, more stable RS232 output signal
Can accept a range of power supply voltages from 5V up to 12V
Has a professionally designed and printed vinyl label instead of the rather amateurish ones I was making myself

The design is [...]

I’m looking for a little bit of freelance work at the moment, if you are interested in someone to help you out with digital circuit design, embedded systems design or programming, application development or even web sites or server back end work, drop me a line at adam@siliconsparrow.com. I’ve put my Resumé online for you [...]

Being in the electronics design business, I am often ordering parts in small quantities and the best place to do that is Digi-Key. But it really annoys me that Digi-key can’t sort by price. When I’m looking for, say, a 470µF capacitor, it gives me 100 different ones to choose from, of course I just [...]

After looking at my sales figures, it seems the majority of my RS232 Rate Converter sales are going to America. I’ve only sold two into Australia ever, so it seems to me that pricing it in Australian dollars is not appropriate for this product, especially since the Australian dollar has been moving quite a lot [...]

It’s taken me a little while to fit this in around my freelance work and family obligations but finally I have put out a version 1.0 of Super Transcribe. This is transcription software for Windows. It allows you to load up a media file (most common formats supported) and slow down the replay so you [...]

One of my peeves about the electronics business is the poor availability of parts. I’d found this brilliant AP1115 power regulator from Diodes Inc. which I’ve been using for months in my RS232 Rate Converter but now, you can’t get them anymore. I haven’t found a supplier who stocks this part since June and my [...]
