I had the opportunity to grow up in a Connecticut factory, where I spent many days after class. Since I was a child my family introduced me to different manufacturing techniques, protocols, and hard work. I still remember sweeping the machine floor when I was eight, or operating the mills when I was a teenager. When I reached a more mature age, I was slowly introduced to technical drawings, drafting software and computer aided machining.

It has been the last seven years where I have become involved with the FABlabs and the maker revolution. In hindsight, growing up around industry was a unique experience that had influenced everything that I have worked towards since.

It is what I experienced in the factories that inspired me to want to study Physics and Mechanics in Paris. As a freshmen at the "University of Pierre et Marie Curie", I helped organise the student association that would later become the first Fablab of the Sorbonne University.

After a few years working for the University I worked with a Parisien start-up to help develope an algorithm and online marketplace to allow for makerspaces to solicit their laser cutting services. This was my first "light bulb" moment where I saw the definite potentional for Makerspaces to adapt their flexibility and reactivity to the fast paced, small series productions of the design, art and Start-up community. The last year, I have been building the concept of a compact factory in the center of Paris.

My goal is to bring all of the rigor and efficiency of the classic factory and marry it to the adaptability and reactivity of the modern "Makerspace".

Introduction to cloud computing and elastic

Our co-working houses another company that only tends to the 3D printing machines. We have installed 20 3D printers, a laser cutter and CNC machine in the center of Paris and we are working to put everything on network so that our small team of 2 co-founders and our 1 co-working resident can run the entire factory.

Our community is only entrepreneurs who are looking to have things prototyped or produced.

We have trimmed out the teaching and community center aspects of the Fablabs for the sake of production and assembly line effeciency. I hope my past experiences and current expertise can help inspire the makers of our new industrial revolution where we design smart, make robotically and sell locally.

One of the most complicated aspects to consider when laser-cutting is the delicate balance between translational speed and laser power. We want to cut as fast as possible, but are there times when it is best to slow down?

We are going to share with our maker community the effects that speed and power have on cut width, kerf angle and engraving depth. This will be the first edition of an ongoing series of articles, with help from Mako. Other parameters such as resolution, engraving direction, and frequency will also have an impact on your work, but none as much as the big two. We will determine to what extent these two parameters have any predictable behavior on the quality of cut. More precisely, when we cut a piece of material we notice that the kerf, or the thickness of the cut, depends on the overall energy that we are focusing onto a point on a work surface.

Laser beam piercing a 3mm-thick material, we see an exaggerated Kerf angle of 1 deg and a kerf width of 0. Each individual square was measured with a micrometer for two different characteristics:.

A normal radar set sends out a radio pulse and waits for the reflection. Then it measures the doppler shift in the signal and uses the shift to determine the speed. Laser or lidarfor light detection and ranging speed guns use a more direct method that relies on the reflection time of light rather than doppler shift.

Radar speed gun

You have probably experienced the reflection time of sound waves in the form of an echo. For example, if you shout down a well or across a canyon, the sound takes a noticeable amount of time to reach the bottom of the well and travel back to your ear.

Sound travels at something like 1, feet meters per second, so a deep well or a wide canyon creates a very apparent round-trip time for the sound. A laser speed gun measures the round-trip time for light to reach a car and reflect back.

Light from a laser speed gun moves a lot faster than sound -- aboutfeet per secondmetersor roughly 1 foot 30 cm per nanosecond.

A laser speed gun shoots a very short burst of infrared laser light and then waits for it to reflect off the vehicle. The gun counts the number of nanoseconds it takes for the round trip, and by dividing by 2 it can calculate the distance to the car. If the gun takes 1, samples per second, it can compare the change in distance between samples and calculate the speed of the car. By taking several hundred samples over the course of a third of a second or so, the accuracy can be very high.

The advantage of a laser speed gun for the police anyway is that the size of the "cone" of light that the gun emits is very small, even at a range like 1, feet meters. The cone at this distance might be 3 feet 1 meter in diameter. This allows the gun to target a specific vehicle. A laser speed gun is also very accurate. The disadvantage is that the officer has to aim a laser speed gun -- normal police radar with a broad radar beam can detect doppler shift without aiming.

This article explains work that I performed to my guns without the assistance of a qualified gunsmith. I claim no responsibility for use or misuse of this article. Again, this article is for entertainment purposes only! A laser sight attached to a handgun allows you to make accurate shots when it is not possible to use the iron sights.

Add a tactical flashlight to the mix and you have a potent combination. In the past most tactical flashlights had long bodies because they were designed to be handheld. If a handgun owner wanted both a tactical flashlight and laser attached, the combination was often bulky and heavy.

Activating the light and laser was sometimes impractical because of wires and pressure switches. Flashlights that used traditional incandescent bulbs often could not stand up to recoil. I was searching the Internet for a less expensive alternative and stumbled on Ali Express. Ali Express is a wholesale outlet for sellers. Retail shoppers can purchase items individually, or in lots at discounted prices. I found a manufacturer in China that produces almost an exact copy of the American-made unit — at less than half the price with free shipping!

The Chinese are well aware of our infatuation with firearms. On the bottom there is a 5 miliwatt red laser that is adjustable for both windage and elevation. The body is made of all aircraft-grade aluminum; believe it or not the domestic versions are made of nylon or plastic.

It took about 2 weeks for the unit to arrive. The unit came in a foam padded case with a small hex wrench for adjusting windage and elevation of the laser. The unit did not come with the 2 required CR batteries; apparently they are considered hazardous and could not be shipped. A quick visit to the Internet brought me to CR Batteries.Replace your error-prone contact encoders with a laser precision gauge and begin realizing immediate production savings.

Once again init was brought to Laser Technology's attention that the market demands had changed and a laser speed measurement device needed to be developed that was lighter, smaller and even more affordable. LTI again listened and our engineers were not only up to the challenge but they set the bar yet again with the TruSpeed S.

This was the beginning of the TruSpeed S family. Not only is the TruSpeed S the lowest priced laser speed measurement device on the market, it is small - weighing in at less than one pound and is very easy to use. In midLTI listened yet again to demands in the market for an affordably priced incident reconstruction tool and the TruSpeed Sx was born. Note: This dual purpose speed measurement and mapping laser was discontinued in mid Together, along with your smartphone, make a formidable team in enforcing the speed limit as they capture and store a picture of the offending vehicle.

S porting the same features as the TruSpeed S, it also has the addition of a built-in tilt sensor, giving this laser the ability to measure both horizontal and vertical distance for crash scene mapping. The TruSpeed S family is designed with police use in mind having a rugged exterior that is weatherproof and a 7x sighting scope that allows officers a wide viewing range and the ability to see clearly in all lighting conditions. The compact binocular-style design sets the S family apart from other TruSpeed devices and makes these laser devices fit comfortably in your hand.
