As the result of this study, spindle speed of 18,000 rpm and feed rate of 2 m/min resulted with minimum surface roughness values of MDF, Ayous and Beech wood for laser and stylus techniques.
The stylus of the laser stimulator was mounted on a wooden stand and an 8 cm distance between stylus and the dorsum of the right hand was maintained.
I recently tested two bigger styluses: the Style-iT 2-in-1 ($25), from Bracketron, and Griffin Technology's Stylus + Pen + Laser Pointer ($50), which is a great gift for executives, or people who like to tease their cats.
The device — called aclock — is another project from hardware maker Hex3 (whose past projects include the YuFu, Nota and JaJa styli; and a smartphone laser blaster gun showed off at Disrupt SF back in 2012).
Surface roughness (Ra) values of specimens were measured by employing stylus type of equipment and laser based robotic measurement system.
Hex3 founder Jon Atherton didn't have any hardware hacking experience when he launched Kickstarter campaigns for the company's debut products, the AppTag Laser Blaster and the JaJa Pressure Sensitive Stylus for the iPad.
A laser is bounced off the tip of the stylus to amplify the minute ups and downs so that the shape of the molecule can be made into an image, and even into a moving image.Using such a device to look at active biological molecules is difficult, however.
Figure 4 shows the photographs of the stationary rings textured with bionic cluster spiral groove (a) and spiral groove (b) where the textured areas appear as darker matt surface, and the 2D profile of grooves marked by the Optical Fiber Laser Marking machine, which are obtained by Dektakxt Stylus Profiler.

The methods of surface roughness measurement are overviewed and the examples of measurement instruments (both contact based on the stylus and noncontact based on white light or laser interferometry) are provided.
