HackSpace Magazine, Issue 13

HackSpace Magazine Issue 13This month’s maker-focused HackSpace Magazine includes my relatively long-term review of an extremely clever, though far from perfect, temperature-controlled soldering ‘station’: the Miniware TS100.

First, some necessary definitions: brushing aside standard, fixed-power soldering irons, you’ll find adjustable-temperature and temperature-controlled irons on the market. The former are, typically, not much larger than a standard soldering iron and include a small knob on the body for adjusting the power and, thus, temperature of the tip. The latter go a step further, reading the temperature of the iron and using the feedback to dynamically adjust the power output to keep the tip as close to a chosen temperature as possible, and most often come with a bulky base station to which the iron is tethered.

The Miniware TS100, and its not-yet-available-in-the-UK successor the TS80, is different. While it’s a fully-fledged temperature-controlled iron, there’s no base station in sight: instead, the iron packs everything it needs into a surprisingly compact body, including a small OLED screen for live feedback and adjustment of its settings.

What’s most interesting about the design, though, is that the firmware that drives its internal microcontroller is open source. It’s entirely possible to download the source code, modify it, and flash it onto the iron with nothing more than a simple USB cable – and many have done that, producing alternative firmwares which either improve its performance or turn it into something else, including a Tetris-playing games console and a functional oscilloscope, entirely.

The TS100 is clever, then, but not perfect. A design which lacks any form of flaring to stop your fingers drifting forward onto the hot tip is one thing, but a larger problem is an ungrounded power design which leaves the tip floating at voltages more than enough to damage sensitive components. Thankfully, the reviewed unit came with a bundled grounding strap – but that leaves you with two wires rather than one, hampering the portability somewhat.

The full review can be read in the print and digital copies of HackSpace Magazine Issue 13, with the latter available for free download now under the Creative Commons licence from the official website.
