PRODUCT SHOWCASE Android smartphone temperature datalogger from Ocean Controls The TagTemp-NFC is a temperature datalogger with a Near Field Communication (NFC) interface. An Android smartphone with the LogChart-NFC app can configure and download data from the TagTemp-NFC by holding the smartphone close to the TagTemp. The TagTemp NFC was designed primarily for monitoring the temperature of medical shipments but has numerous other uses. It is fitted with an external temperature sensor on a 30cm lead (other lengths are available) and is able to store up to 4000 records. The internal battery life is typically 400 days. The LogChart-NFC app allows the user to view and graph the temperature history. The NOVUS Cloud Portal is offered as an optional service to TagTemp-NFC users that make use of Android smartphones. LogChart-NFC android app can be configured to send out temperature recordings read from TagTemp-NFC devices straight to the internet portal. Once stored on NOVUS Cloud, records can be checked from any internet browser. Price is $85+GST.

A: When it’s a THREADBOARD! We’ve seen a lot of breadboards in our time but this has to be on of the fanciest, best-thought-out and easiest-to-use ever. For a start, the Threadboard isn’t simply a breadboard – it’s a system. It consists of a thick (4mm) 5083-grade aluminium base (a great heatsink!) with a matrix of 3mm tapped holes. The Threadboard is also available in HDPE plastic and both have two removable side bumpers for protection. The holes are spaced to accept a large (830 hole) and small (400 hole) somewhat traditional prototyping boards – these are amongst the nicest we’ve seen. But wait, there’s more! In addition, the Australian-designed and manufactured base is also drilled and tapped to suit a variety of popular boards such as Arduino, Raspberry Pi, Beagle Board and Intel Gallileo. Because of the number and spacing of holes, a range of PCBs can also be fitted. Add to that the range of accessories, including feet, long legs, stand-offs, M3 screws in various lengths and washers and you have a real development system – suitable for the dedicated engineer or the raw hobbyist. And unlike any prototype system we’ve ever seen, both sides of the Threadboard can be used (with links through unoccupied holes). This is one product that everyone involved in electronics, at any level, should have on their workbench. We know where one is staying!
