Retrospective Review: Traxxas Bullet

Slash, Revo, T-Maxx, Stampede, E-Maxx, Rustler, Slayer, Summit, Jato and the list actually goes on. If you're into RC, these are household names. And, of course, they're also all trucks and trucks made by RC giant Traxxas. But, even if Traxxas is arguably currently the biggest name in RC trucks, the company out Texas didn't start with trucks. It kicked things off with a few buggies (The CAT and Bullet) and an on-road pan car (the Fiero).

Brushless Motors: Sensored vs. Sensorless

There are all sorts of motors that qualify as brushless motors, but a significant point of difference between brushless motor designs used in RC truck applications is sensoreless vs. sensored operation. Explaining the difference is best done by defining what sensored means. All brushless motors used in RC applications have three main wires, but sensored motors have an addition multi-wire loom that connects the brains of the speed control to the motor.

Similarity Between Induction Motor And Transformer

The development of a wound-rotor induction motor from a single-phase transformer is depicted in Figure 7.1. In Figure 7.1(a), we see a section through one of several possible arrangements of a single-phase iron-cored transformer, with primary and secondary windings wound concentrically on the centre limb. In most transformers there will be many turns on both windings, but for the sake of simplicity only four coils are shown for each winding. Operation of the transformer is explored in Section...

Reciprocal Mixing

The dynamic range of a radio receiver in the range from the minimum discernible signal to the maximum allowable signal (measured in decibels, dB). Although this simplistic definition is conceptually easy to understand, in the concrete its a ttJe more complex. SeveraJ definitions of dynamic range are used (Dyer, 1993). One definition of dynamic range is that it is the input signal difference between the sensitivity figure (e.g., 0.5 puV for 10 dB S + N N) and the level that drives the receiver...

Deep bar rotors

Deep Bar Rotor

The deep bar rotor has a single cage, usually of copper, formed in slots which are deeper and narrower than in a conventional single-cage design. Construction is simpler and therefore cheaper than in a double cage rotor, as shown in Figure 6.11. The deep bar approach ingeniously exploits the fact that the effective resistance of a conductor is higher under a.c. conditions than under d.c. conditions. With a typical copper bar of the size used in an induction motor rotor, the difference in...

Rotor construction

Two types of rotor are used in induction motors. In both the rotor 'iron' consists of a stack of steel laminations with evenly spaced slots punched around the circumference. As with the stator laminations, the surface is coated with an oxide layer, which acts as an insulator, preventing unwanted axial eddy currents from flowing in the iron. The cage rotor is by far the most common each rotor slot contains a solid conductor bar and all the conductors are physically and electrically joined...

Draw Circuit Diagrams Using These Tools

In the virtual world an electronic component is represented by a symbol. These symbols are used to represent graphically the diagrams circuit in 2D or 3D designs. A diagram is used to showing how are connected the electronic components while using simulation can be determined the design defects and deficiencies. While all electronic components are represented by symbols , the wires are represented as straight lines.

The Proto Cam - An Easy Way To Make Projects With Your Camera Module

Just before I released the original ProtoCam, the Raspberry Pi B+ was launched, with its different layout and 40 GPIO pins. Soon after that (and as predicted by many in the Pi community ) the A+ was released - the smallest Raspberry Pi so far I couldn't resist making a prototype 'ProtoCam+ ' for the new Pi models, and I'm so happy with it that I've decided to release it as another Kickstarter project.

How To Install OSMC On A Usb Stick For Your Raspberry Pi

Installing OSMC to a USB stick isn't as simple as you would expect Ever since the Pi 2 came out, I've been a little bit unsettled with my choice of Raspberry Pi Media centre. I was originally a happy user of RaspBMC, but as the Pi 2 wasn't initially supported by RaspBMC, I moved over to OpenELEC and have been reasonably happy ever since. RaspBMC has since come to the end of its busy life, with OSMC (Open Source Media Centre) taking over.
