Relatively new to freediving/spearfishing and am a bit confused with the different information conveyed online regarding weight belts and how much lead weight I should be using. I know the best way is just to go into the water and experiment, however I want to have a somewhat accurate estimation so I can buy weight accordingly.
I recently bought a 5mm 2pc open cell wet suit. I weigh roughly 73kg/161lbs and using this calculator (http://www.divebuddy.com/calculator/weight.aspx) (Selecting Experience: Novice/No Tank - Freediving/Salt water), it tells me to use 9.5kg/21lbs of weight. Other rules of thumb say to use 1kg for every mm of wetsuit + ~1-2kg, which is approx 7kg/15lbs.
My boss asked me to draft pieces of a clock from schematics in a book for a side project that is not work related. I use AutoCAD 2012 infrequently for work doing GIS/surveying type of stuff so I'm not a complete beginner but I'm not too familiar with drafting. I'm wondering if there's an easy way to draw the curves, angles etc - it doesn't have to be identical to the schematic so long as the hole sizes are correct I believe.
If anyone wants to point me in the right direction, that would be great. Hell, I'll give you permission to draft it for me if it's easy :P It's probably good to note that I'm using metric so I'll have to convert all measurements.
As the title states, I'm looking to see what I have installed in my car. I'm a complete amateur when it comes to car audio, I know bare basics but nothing of wiring or the technical details; I've read the sidebar material to familiarise myself but I'm not building a system from scratch, so would like to know what I'm working with in my own car. I purchased the car from my brother who purchased it off his friend and I don't wish to quiz either of them, for reasons I don't need to go into detail.
Currently the sound is amazing however I'm looking to put a subwoofer/s to complete the system as it is definitely missing the low range. I didn't even know ther
