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 SSID can serve a "beacon" and "advertising" opportunity. Coupled with some nefarious networking tricks on the Raspberry Pi, I can make a small device that I can carry with me to advertise my site to everyone that is nearby. How did I do it ...
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 products, etc. I call it my "room", it gets a little cramped, but that's the least of my issues. What I really don't need are interruptions. Creatives and coders would probably best sympathize with me - once you get in the "groove", find your "muse" or get in t ...

Stocking up on Wi-Pis

Posted by lui_gough Top Member Jul 19, 2015
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 to help your Raspberry Pis and other devices "go mobile" for basic data-shuffling.   I've gone into depth, tearing apart one for all to see on my blog here: http://goughlui.com/2015/07/19/teardown-element14-wi-pi-usb-wireless-802-11n-150mbits- ...
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 commended it for the convenience feature of being able to detect an open fuse without actually taking it out and testing it by using the Earth Bond test selection as the manual said ... Had I been a little more awake this morning, I might not have had to use this f ...
Recently, after having posted a review of the Raspberry Pi 2 here, I was tipped off by mcb1 that his Raspberry Pi 2 looked a little different. A little discussion also had clem57 letting me know of some RAM differences between original RPi boards which got me wondering - what sort of variations of Raspberry Pi 2 are out there?   For research purposes, I collated photographs from different online shops, forums, from my own board, from the board my colleague received, and from Mark and put i ...
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 from here. To be completely fair, I have gone back and added the link for it back into Part 1 - but as to why I didn't find it when I was doing my searches still remains a mystery.   The manual itself fully details the board's design topology, cap ...
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 would appreciate them, so lets keep this show rolling . Before anyone asks - no I didn't receive the items, prepare them, and get something working all in a day.   The parts themselves arrived on 19th January 2015, right after I got back from my internati ...
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, because doctorcdf sent me an e-mail, letting me know that I was going to get a little bonus with my other RoadTest - I would be receiving the Arduino Uno, Arduino Yun and Infineon RGB LED Shield as well for my own tinkering. I'm so very lucky to hav ...
Well, it's past new year and I finally got a little time to sit down and do something. The first thing I did was to publish my review on the Christmas present to myself, alluded to in my last blog post here.   So, what was the present? An Agilent U1241B DMM and Accessories of course! You could've guessed it if you were following my postings about 3.5 digit multimeters and the like.   Without any further ado, here's the mega-article - a self-funded RoadTest: Review: Agilent U1241B 4-D ...
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 opinion of the product is, one year after I started using it. After all, some products are all fine and great in the "honeymoon" phase, but after a bit of usage, you really get a feel for the developments, limitations and annoyances of the product and they're wort ...
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 hobby. It's been a while since I ventured to their doorsteps, but just last week and again today, I decided to pay them a visit.   One of the biggest perks of living in Chester Hill is being less than 10 minutes walk from the element14 Australian headquarter ...

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 thoughts on my personal blog at http://goughlui.com, but I suppose I might find a use for this blogging space for particular element14 related things - like extensions on RoadTests and the like.   - Gough ...
