Weekend Project: MMA8451Q Accelerometer as a Microphone?
Last weekend was the Australia Day long weekend, so aside from chasing Shortwave Radiogram broadcasts and posting radiofax galleries, I also decided to build something I thought was rather interesting. In the past, I remember vaguely seeing articles about how … Continue reading

Review, Teardown & Test: Portable USB 18650 Li-Ion Rechargeable Fans (x3)
It’s summer in Australia and this one is another scorcher! Our summers do get somewhat hot, but not usually this hot. Data from my own weather station in my backyard shows that the temperature over the period from Christmas Eve … Continue reading

Project: DIY Weather Station & Displays
It’s summer in Sydney and we’re definitely feeling it. In the west, there are often strings of 32 degree Celsius or above days coupled with dangerous storm activity, so staying comfortable is not always easy even with the modern conveniences … Continue reading
RoadTest Review: B&K Precision BA6010 Battery Analyser
If you’ve been wondering why it’s been quiet around here for a while – it’s because I’ve been unusually busy. One of the things I’ve been working on is a review of the B&K Precision BA6010 Battery Analyser I received … Continue reading

Repair: Soyoung S-C18 Soymilk Maker

Note: Bosch Sensortec BMP280 vs BME280 Sensor Confusion
While looking around for some cheap environmental sensors, I came across the seemingly ideal and relatively popular Bosch Sensortec BME280. This is a digital I2C sensor that can operate at 1.8 or 3.3V, providing temperature, humidity and barometric pressure measurements … Continue reading
Tested: MINI-360 (MP2307-based) “3A” Buck Converter Module
As mentioned in my earlier Canton-Power buck-boost module review, voltages from batteries are rarely exactly the voltages you need to safely and reliably power your electronic creations. While that converter was rather acceptable, the efficiency wasn’t exactly stellar. In the … Continue reading
Tested: Canton-Power DDO603SA 3.3V Buck-Boost Converter Module
If you like to experiment with electronics, sooner-or-later you’re going to build something you’d like to use in a portable way, perhaps running off batteries. While things that run off 5V are easy to cater for, as USB is ubiquitous, … Continue reading
Project: Generic Electronic 57 LED Hourglass Kit (TJ-56-205)
I couldn’t help myself, so once I finish one kit, it’s often straight onto another. This kit was sold as an electronic LED hourglass and was a little more expensive at AU$3.07 including postage. Compared to local suppliers, this is … Continue reading
Project: Generic 18 Red LED Flashing Love Heart Kit (TJ-56-30)
Another day, another classic kit. It seems that LED heart-shaped displays are a timeless novelty, so after building a multi-coloured chasing heart and a breathing heart, why not a flashing one? For just AU$1.68 including postage, I managed to score … Continue reading
Project: Unbranded Generic NE555+CD4017 SMD LED Chaser Kit (YL-117)

Project: EQKit HBL-22 Breathing Green LED Heart Kit
I just can’t help myself, so I grabbed another kit off the pile and decided to build it. This is yet another “cheap” kit from eBay intended for educational use. This particular kit is an EQKit HBL-22 “breathing” LED heart … Continue reading

Project: Unbranded 38 x 5mm LED DIY Lamp Kit

USB Connector Resistance: Another reason for slow phone/tablet charging
It was back in 2014 when I first published about USB cable resistance as one reason why your phone or tablet might be charging slowly. At the time, quality cables with good gauge wires were hard to find, and many … Continue reading

Repair (?): ICOM IC-R75 that won’t turn on!

Review: Uni-Trend UT210E Mini Clamp Meter

Teardown: RadioShack Amplified Telephone Earpiece (43-229)

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, 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
