This sounds painful to people like me who like to abuse their drill bits by using them to oblong holes, grind edges, and countersink both sides of the hole. It needs special settings for special people… |
|

[marked-for-del3tion] magic. Poster does not explain how the sound will be made. Is it due to some interaction between the drill bit and the medium, or is it just a preset audio sample that is emitted and distorted based on some input from an internal leveling device? |
|
| |
If you choose the former, then it's definitely magic as I assume you will not be able to reliably control this noise. |
|
| |
If you choose the latter, then it's just silly to add noise to an already noisy affair and I bone it. |
|
| |
Why not just add a level to the top? |
|
| |
The level isn't always handy to look at, when you're looking at the workpiece. |
|

You are quite correct [iron_horse], and
a level
will not monitor lateral
deviations unless it's a complex one
that needs a close eye -not easily
achieved when drilling a hole with the
hammer action on!
[Cwp] You can
always turn
it off when you don't need to use it.
[daseva] Drills can be made
quieter and
there are so many ways to generate a
tone that I
didn't bother burdening the idea with
that
aspect. As for monitoring the position
and
linking it to the modification of the
tone, that
sort of simple feedback system is not
exactly
what I would call magic. |

An auditory sweet spot would be good.
It just needs an angle pre-set and I want one. |
|
| |
Alright. I've retracted the mfd. But, seeing as drills and noise are inextricably linked I hope you reconsider your lack of burdens. |
|
| |
I think a guiding device would be more effective. The guiding device would be fitted onto the drill and would keep the drill perpendicular to the work surface. I've found a patent that illustrates this idea nicely (link). |
|
| |
It could use GPS for positioning |
|
| |
+ Readily bakeable, except for the horzontal drill position.
An optically sensed bubble-level would work fine for vertical positioning, but it's not clear how to detect deviations left and right when the drill motor is held horizontally. GPS is not nearly accurate enough for the +/- 1mm precision required. |
|
| |
I am aware of other guiding devices, but
these have a few problems, one of which
being that they partly obscure the work
area. They are also not adjustable. I
envisage a type of closely monitored
sensitive mercury tilt switch, linked to a
processor then in turn the sound
generator. |

//I envisage a type of closely monitored sensitive mercury tilt switch//
Mercury?
Three axis MEMS accelerometer and microcontroller. <nods assertively> |
|
| |
The deviations left and right are not distances, but angles. +/- 0.5 degree (thats angular not temperature) is probably good enough, and achievable with GPS. Accelerometers also good. Mercury bad. |
|
| |
I don't think 3-axis accelerometers would be helpful in accurate angle measurements, since I they detect linear acceleration. But a gyroscope (my favourite toy) would be very good. It could be spun up by the drill motor and a one way clutch. The datum could be set on a nearby object (corner of the room). |
|
| |
[Ling] with the added advantage that tilting the drill from that axis could make it screech. |
|
| |
// don't think 3-axis accelerometers would be helpful in accurate angle measurements, since I they detect linear acceleration//
What about the constant one, straight down? |
|
| |
[Copro...] Heh, heh. They really need to come up with a better name. And another laugh on "gutter-snipe" it seems to have gone now. |
