New Product – Lynxmotion UAV / Drones 16mm Aluminum Clamps

At Lynxmotion UAV we were looking at the future of our UAV / Drones lineup and had to take decisions for our next models. There are tremendous ways to make a UAV frame and we wanted to keep the Lynxmotion soul of being modular and expandable. Something you can use to build your frame design and be able to reuse the parts on other projects. With that objective in mind, we chose to explore a Tube and Clamp system and create our own Clamps that would solve the major issues normally associated with that type of hardware. This was a first step and now with the right building material, we can develop our next UAV / Drones around it.

Lynxmotion UAV 16mm Aluminum Clamps

Lynxmotion UAV 16mm Aluminum Clamps

Common issues with clamps available on the market:

  • Most use two screws that sandwich everything from top to bottom plate of the frame and a nut. This mean you have to tight every Screw / Nut with two tools from top and bottom and that your frame is  loose until all the tubes are inserted and properly tightened. This is less than convenient and quite hard to assemble.
  • Weight is sometimes an issue with injection molded clamps since they need to be bigger in size to hold the torque applied to properly squeeze the tubes.
  • Plastic clamps are also prone to slipping. The plastic clamps need to be over-tightened for them not to slip and even then, they still do.

Lynxmotion UAV 16mm Clamps Features:

  • Strong construction made from billet Aluminum and milled by CNC equipment.
  • Easy assembly design with two screws per sides that hold the clamp on it’s plate before final assembly.
  • Two 4-40 x 3/4″ will be used for final tightening of the tubes. One on each side plates.
  • Only one allen key is needed since there is no use for nuts because the body of the clamp is threaded.
  • Industry standard holes spacing at 25mm between the centers make them compatible with various frames on the market.
  • Four threaded holes are available for optional mounting and use 2-56 screws.
  • Middle top hole that can either be used for mounting the clamp or to add a setscrew and tighten the tube even more to avoid slippage.
  • Anodized Lynxmotion orange for durability and look.
  • Low weight of 8.64g with full hardware (all screws and clamp parts, even the 2-56 screws)

Because weight is Important:

Talking about weight, one can think that a metal based clamp will be heavier in the end than a simple injection molded version. Even if that can be the case, a properly designed Aluminum part can be lighter in less critical areas and keep it’s strength while loosing considerable weight. We weighed a set of injection molded clamps that were used on DiaLFonZo-Copter frames in the past and the new Lynxmotion UAV version and we not only equal the weight but, we are actually lower!

Manufacturing Process:

Here you can see the process of making the prototypes by our factory. They kindly provided us with this video which shows how intricate making an Aluminum part can be.

 

 

Clamp Dimensions:

If you are looking to design your frame around our clamps or simply would like to make sure they fit on your current UAV, here are all the dimensions:

GT06 GPS TRACKER REVIEW

Posted: 28 Mar 2015 08:07 PM PDT

There are many reason to incorporate a motorcycle anti theft security system that enables the user to remotely control the motorcycle and or cars alarm by SMS (short messaging system). Putting up an alarm that only alert people within the vicinity of the parked vehicle without alerting the real owner is not that efficient and only by these so called GSM alarm can do the job properly. Once an alarm was detected by the unit, it will send a series of text to the owner notifying them of the alert. In this article. I'll be reviewing the cheap GT06 GPS car tracker alarm that is so cheap and, easy to install unit. It has a downside though and will practically write it down at the very last part of this review.

GT06 Car GPS Tracker GPS/GSM/GPRS Tracking Cut Off Fuel Web-based Gps Track for vehicle motor car alarm


When it arrived, I immediately unpack the box and see whats inside. It is a complete system already and only a GSM sim with of course enough CREDIT to make it work.

Installation is an amateur work too. Take a look closely at the photo for the right installation procedure.

(photo courtesy of the watermarked site)

The relay can be use to cut anything like CDI positive supply, pulser coil signal to ignition, and with just a simple text code to the system will entirely disable the IGNITION system and halt the operation of the vehicle and going nowhere but the side of the road.

For the installation. It must be hidden of course, since this is i think the cheapest out there, no external antenna was provided thus it can be put everywhere like the U-box compartment, but there is a precaution since no external antenna like those of the bigger and efficient units. Any sort of metal within near the unit to where it will be placed on your motorcycle will entirely affect the performance of the GPS function, nonetheless, that function is only used for tracking the vehicle to where it was on a MAP after triggering the cut engine alarm.

Instructions


A WORD OF CAUTION when ordering this online, make sure the supplier already made an account of the tracker to the WEB BASED GPS positioning software to where you must log-in to monitor and track the position of the unit. We really do not know why ours was not registered on gps588.com, and having to seek other software just to pinpoint the location on a GOOGLE map.

PROS:

  • cheap 
  • sleek design
  • easy to install
  • good idle current consumption (battery will last for days up until the engine is started to charge the internal battery supply)
  • only 4 wires is needed to connect it on your vehicle
NOW the CONS

we all know CHEAP means..you get what you paid for

CONS
  • poor GPS satellite lock in. Having problems to to get a fix satellite that will enable the GPS track location of the unit, since it has no external antenna provided due to sleek design, poor GPS signal is what you will get.
  • Ain't WATERPROOF..so if you are installing this on a motorcycle, make sure you cover it with ZIPLOCK plastic.
  • Installing it near any metal part of your vehicle is a NO-NO..when i do found a fix satellite for the tracker and put it near a metal on my motorcycle, GPS led indicator stop flashing indication of GPS satellite searching again.
  • If it was not directly registered by the supplier to their own global positioning system tracking system, You will not have any means of tracking the unit when you do registered online, it will only tells you..: NO data receive by the GPS blah blah blah" in other WORDS...."OFFLINE"
Up until now, SMS alarm is GOOD..(A-OK)...but the GPS tracking of the unit is a PAIN in my head..still when it comes to remotely disabling the entire ignition system works 99%..

With 5 star rating of the unit..I'd go for 2.5, the lower idle current consumption is great when it comes to waiting for anything to not good happening outside when you are not near your precious vehicle.
