Hack: Customize the LED Shake-Stick Images

As I managed to construct the LED shake-stick kit just yesterday evening, I wasn’t entirely satisfied with its operation. For one, the images weren’t particularly inspiring. I mentioned that it should be possible to replace the images in the ROM … 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

Review, Teardown: “Generic” BT-168 Battery Tester

A short while back, I posted about this generic battery tester, which was a cheap and nasty clone of a model which was quite popular, which I used frequently as a child. In my quest to buy it, I came … 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: 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

Review, Teardown: Crest USB 2.0 All in 1 Mini Card Reader (CZUSBCR)

This particular review and teardown is a little different. In fact, this card reader was not one that I had purchased, since I normally swear by my Transcend RDF8‘s as being a decent performing, reliable and compatible reader at a … 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

Review, Teardown, Reverse Eng: Generic Battery Tester

As a kid growing up in the 90’s, one fond memory I had was sorting through piles of batteries to see which ones were good and which ones needed to be discarded or recharged. With many toys and appliances using … Continue reading

Review, Teardown: Nitecore HC60 1000lm USB Rechargeable Headlamp

After I wrote my review of the Nitecore MH10, I decided to ask Nitecore (nicely) if they would like me to review their other products, as they had a reviewer’s section on their site. To my surprise, they were happy … Continue reading

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

Review, Teardown: Keweisi KWS-V20 USB Tester

It’s almost been one year since I’ve looked at “USB charger doctor” style devices, but having reverse engineered, tested and modified one, I didn’t think I’d ever bother with them again. That was, until I saw the Keweisi KWS-V20 USB … Continue reading

Teardown: A failed SUNeCON S-SP/38 38W CFL Globe

SUNeCON is not a brand that’s often heard around here, and for good reason. This particular CFL is a very special globe – at least to me anyway. I was walking through a “$10” shop in Hong Kong back in … Continue reading
