Hi Crusty. That type is good. Contact the seller and see if you can negotiate a bit on the postage - bear in mind the figure I gave would have been to Australia, it might be cheaper to the UK. You may find others - I think I searched on "hand nibbler" to find that one, but try "nibbling cuttter" and other such search terms. There are some very tasty purpose built electric ones out there as well, which is why I tried including "Hand" in it. Good luck....
Hi Crusty.. Don'tcha hate it when one of your tools passes on to tool heaven and you can't find another one? I will keep my eyes open and let you know if I find one.. I can thoroughly recommend the drill-accessory ones but I see your point, my hand one is also more suited to square holes, though it is going the way of yours I fear.....
Most of the time, it's just a nail and a hammer . It's the breakable medium (e.g. glass) when you have to get creative. Microtorch (and anything combustible) gets me excited easily but I couldn't use it as much as I'd like to. Old soldering iron could be used to make holes in PVCs - of course, you wouldn't use the tip directly, you would wrap metal wire of needed diameter on it . And then there are chemicals - lovely sulfuric acid made more holes in my clothes than in the objects of my experiments.
It looks like not everything is made in China; for example, on Amazon I found a German made Bosch drill (for >$400) and a German made Fein drill (>$800). I believe that Proxxon rotary tools are still made in Germany, but they're not drills.
BTW, just about everything is "globally sourced", including a lot of stuff that's "Made In China". For example, most memory (DRAM, flash) isn't made in China.
Also off topic: my vacuum is a German-made Bosch canister vac. The price was reasonable (unlike Miele and some others). It's 8 years old and still going strong; the Dyson canister vac was more expensive, made in Malasia, and had a lot of quality complaints.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
