Project: A Major Upgrade to My Workstation

Over the past two years, I’ve been seriously thinking about upgrading my workstation for a number of reasons. Despite this, I could never actually make the commitment, as my computing needs are quite high and the investment would be sizeable. … Continue reading

Teardown: RadioShack Amplified Telephone Earpiece (43-229)

After my experimentation in building a T-coil receiver on my own, it seemed that the unit did have some issues which I eventually corrected. While it seems the schematic may have been a victim of a transcription error, I thought … Continue reading

Recovery: “Musical” SyQuest Cartridges with DoubleSpace Compression

I’ve long offered my “volunteer” data recovery services for those with 44/88/200Mb 5.25″ SyQuest disks, and it’s been a little while since my last SyQuest recovery post. Just when I thought that maybe nobody else would be interested in it, … Continue reading

Project: AT89S52-based LED Shake-Stick Kit

Just recently, I built an AT89S52-based LED Heart and an LED Clock Kit, so I wondered just what else is out there that is AT89S52-based. Searching around on eBay led me to a “shake stick” kit for AU$4.37. It looked … Continue reading

Project: AT89S52+DS1302-based LED Clock Kit (EC1204B-Equivalent)

Since I started along the line of garish LED-adorned kits, I thought I’d order a few other kits built around the AT89S52. In this case, it was a clock based around the AT89S52 80C51 microcontroller and a DS1302 real-time clock. … Continue reading

Project: AT89S52-based Multi-Coloured LED Heart Kit

As my radio kit-building adventures have reached the “bottom” of the eBay well, with most of the kits available being built, I decided to branch out into other “low cost” kits to see what they are like. Most of the … Continue reading

Project, Reverse Eng, Repair: ATmega328-based “Transistor Tester” Kit

A common complaint and reason for the falling popularity of electronic kits is that none of them really let you build something that’s really useful that you couldn’t buy pre-built at a lower cost. I believe this complaint does have … Continue reading

Project: YYDZW BH1417F-based Stereo FM Transmitter Kit

While I was browsing the listings of electronics kits on eBay, I came across this particular stereo FM transmitter kit but I didn’t think much of it. In fact, given the chance to buy it, I passed over it twice. … Continue reading

Project: Sainsmart Forty-9er “3W” 7.023Mhz QRP CW Transceiver Kit

Even though I’m insanely busy, it seems I just can’t help myself when it comes to cheap Chinese kits available on eBay. Of course, having built most of the cheap radio-based kits already, there isn’t really that much to build … Continue reading

Project: CD2003GP+SC3610D FM Receiver w/LCD Alarm Clock (74-108Mhz)

My little “mission” to build random Chinese radio-kits from eBay continues with this rather odd and difficult kit. Unlike the other kits, this is the first to come with an LCD display, but is advertised strangely as FM Radio Kit … Continue reading

Project: S66D/E 9018-based AM Radio Kit

If you’ve been wondering about all the random radio kits I’ve posted about recently and had the thought “Gee, that guy must’ve just looked for any cheap radio kits on eBay and bought them all!” You’d be absolutely right. In … Continue reading

Project: 7.023Mhz PIXIE_V3 QRP CW Tranceiver Kit

After I stupidly decided to push the limits on the PIXIE_4.1 and subsequently destroyed its amplification, I wasn’t too concerned. Being the prepared sort, when it comes to low-cost kits, I sometimes buy two in anticipation that maybe some parts … Continue reading

Project: 7.023Mhz PIXIE_4.1 QRP CW Transceiver Kit

Going along the same vein of “radio kits”, this one is a little bit different. This one is a do-it-yourself PIXIE 7.023Mhz QRP transciever intended for amateur (ham) radio morse code (CW) usage. It doesn’t have many specs, but apparently … Continue reading

Project, Reverse Eng: Hex3653 AV2B Stereo FM Receiver Kit

When I built my last radio kit, I lamented that there were some kits out there which were mainly black-box which don’t offer that much of an opportunity to learn about what is actually going on. While I was dismissive … Continue reading

Repair: Apple Macintosh PowerBook 100 AC Adapter (M5140X)

Since I made my posts about the PowerBook 100 that has “become” mine, I faced a dilemma as to what to do next. Even though I didn’t get too many people chipping in their opinion, it seemed that a full … Continue reading

Project: Paeansonic CF210SP CD9088+CD7642 AM/FM Radio Kit

It’s been a bit quiet around here lately – I’m just swamped with work, and it never quite goes away, but neither does the desire to do something for my own enrichment and enjoyment … and the desire to blog … Continue reading

Project: Arduino Grid Mouse Clicker (and other Pokemon Go-related fun)

Project: ADSB-pi Mark 2 with dump1090, hostapd, dnsmasq & text logging

Teardown: Osram St151 4-22W Series Glow Starter

Project: Scanning Sydney’s DAB+ & FM Broadcasts

While on holiday in Hong Kong, I did some scanning of broadcast services over there and SydneyCityTV tipped me off that there were indeed slideshow services on DAB+ here in Sydney as well. It’s funny how we “get used to” … Continue reading
