Gough Lui

433Mhz Reverse Engineering Part 2 - Burning Questions are Answered

Gough Lui

I couldn't help but wonder, based on the previous posting and the discussion, exactly how did the 1 million combinations come about? Also, what are the functions of the fixed bits? Are they fixed pre-amble as my experience would suggest? Are there mo...

Woefully Insecure: Remote Control 433Mhz Power Sockets

Gough Lui

It's been a while since I've had the time to post anything around here. Luckily, I had recently just submitted my PhD thesis so that gives me a chance to take a short break and do some of the stuff that I like. Recently, I came across a bunch of...

Gough Lui

Some of you might have gotten a little suspicious seeing that I had stocked up on Wi-Pis earlier. Well, you are right to be suspicious, as I was thinking of a little Wi-Fi-based project. I came to the realization that a wireless network's ...

Project: Raspberry Pi Door Sign in Under an Hour!

Gough Lui

When it comes to me getting some work done, there is really only one place in the house where that happens. Coincidentally, it's the same place where I get some sleep, hack about with electronics, write code, record videos, take photos of product...

Stocking up on Wi-Pis

Gough Lui

The end of financial year sales at element14 definitely got me shopping around the Connect catalogue, where a deal leaped out at me - the heavily discounted Wi-Pi wireless adapter. Sure, it's a pretty basic device, but it's handy to have a few around...

An Expensive Mistake: I blew a fuse, and now I feel like a fool!

Gough Lui

Last week, I delivered a review of the Keysight U1461 Insulation Resistance Test Multimeter. It's a lovely unit, and as with all new and wonderful tools, it's become my new "go to" unit when it comes to experiments. In my review, I ...

Internet of Holiday Lights Off-RoadTest - Part 3: Current Waveform, Optimizing LEDs & I2C Commands

Gough Lui

Suffice it to say, an early criticism of mine from Part 1 was a lack of decent documentation for the board itself. Oh how I'm forced to eat my words as I realize that there actually is a perfectly good board manual from Infineon that you can grab...

Internet of Holiday Lights Off-RoadTest - Part 2: Hardware Preparation & First Light

Gough Lui

The timing of these blog posts is a bit irregular because of previous engagements with medical appointments, my PhD, other RoadTests and my personal blog. It's not easy to find the time to write the posts sometimes - but I'm sure somebody wou...

Internet of Holiday Lights Off-RoadTest - Part 1: Unboxing

Gough Lui

Just around Christmas-time, element14 ran a RoadTest entitled Internet of Holiday Lights. I was a bit busy around that period, with overseas conferences to worry about, so I never bothered to apply for the RoadTest. Alas, I didn't end up missing out,...

One Year after the RoadTest: Keithley 2110 Digital Multimeter

Gough Lui

Seeing I have this blog space which I promised to put some element14 related content on, and I have about half an hour that I can spend, I thought I'd take a look back on some of the RoadTests I've been involved in and see just what my opinio...

Gough takes a trip to element14 ... just one of many!

Gough Lui

I think it's no understatement to say that element14's probably my favourite place to shop, of all places. A wide variety of parts, tools and test equipment - it's pretty much most of what I need to repair and test things as part of my ho...

Blog Post #1

Gough Lui

Wow. I didn't realize element14 had its own blogging service as well. Hmm. Well, I'm a bit of a random person, so I like random things. My mind never sleeps, but the time to write posts is always limited. For now, you can find my latest tho...
