Another item in the post this morning – for when the old fashioned inclinometer will no longer do – how about one powered by a pair of AAA batteries… this one came complete with full English instructions from GearBest.
Here’s the link: https://goo.gl/sBVWVT
A neat little gadget, the “Mini Digital Protractor Inclinometer Angle Gauge” is around £12.40 (free shipping) and while not something most of us would use every day, is a lot more convenient than my old spirit inclinometer and probably more accurate. I end up using such tools pretty much on a once-a-week basis.
Resolution 0.05 degree, accuracy +-0.2 degrees, repeatability 0.1 degree.
This handy pocket inclinometer (unlike my trusty old spirit level) has buttons for zero (for relative measurement – good), backlight and hold. I took my own photos but in this case the stock photo on the GearBest site is better. Around the back are 4 screws (they provide a screwdriver) to remove to fit or change the two AAA batteries.
So, there it is.
Now, don’t get me wrong, this is of course not designed for hackers, but on request I pulled out all the screws and can I HELL get the back off. The battery cover opens no problem (just as well, really) but getting to the innards for hacking looks like a job involving finger-nail damage, so I’m going to give that a miss for now if you don’t mind.
