How I built a RC Hovercraft

Last weekend one of my friend came to me and told me about an HOVERCRAFT event, and I thought I will give it a try as I had never in my life built a RC Hovercraft. So we thought we will learn something while building and we started with just a top-view diagram my junior made it on a drawing sheet. We got two extremely power full brush less DC motor. We did not buy the motor for the hovercraft. we bought two motors to build a twin engine aircraft and thought we can use it for this purpose also. The motors were too power full, hence we had to maintain the power to 50% and max 60%. We encountered several problems like the air cussion was not proper. we had to come up with the perfect design by trial and error. first we used flex banners for air cussion. unfortunately the flex was a bit heavy for the aircraft. later we faced another problem once the hovercraft started to hover, it started to rotate because of the rotational force. then the new problem was the rudder we made was small. we were unable to extended the rudder size as the event rules require our crafts to be well within 50x50x50. later we figured out the solutions for all the problems. then the last problem was that ours was not a programmable RC. So it was difficult to control two motors with the RC. Finally it came to life and here is a clip of the hovercraft.

Switch debouncer using SR Latch

We use switch in our day to day life to switch ON/OFF a bulb or a fan or any electrical devices. But when we use switches in digital circuits, we observe a phenomenon called bouncing. This occurs because, when we turn the switch, the mechanical parts vibrate. i.e It toggles between ON and OFF state for some time until the mechanical contact attain equilibrium. this vibrations are minute and are not at all noticeable in electrical circuit. where as in digital circuits, these vibrations create pulses. which are detected by circuits which results in an error. In the above circuit, there is a switch connected to VCC. You can toggle it between terminal 'a' and terminal 'b'. which as a voltage drop of 'Va' and 'Vb' respectively. In digital circuits if you can observe, it takes a finite amount of time to toggle between terminal 'a' and 'b'. which might approximately take 15ns. Now let us consider the terminal is at 'a'. we...

ADXL 355 Accelerometer

A few days ago I went to get components for a project I was building. and came across a 3-axis accelerometer. So I decided to test it and make a post to give you an idea of things work and how you can use it. ADXL 355 The accelerometer I have is ADXL 355 v2.0 board. there is are 5 headder pins, ground, 5V supply, X-axis output,Y-axis output and Z-axis output. It is quite compact. The one I have measured around 15mm x 15mm. These sensors are low cost. And can be incorporated in Projects or robots we build. The ADXL 355 board I have has an onboard Red led (smd) for the indication of power. The accelerometer has a wide range of applications. ADXL 355 is a basic accelerometer which gives analog values for all the three axis depending upon the position of the IC. ADXL 345 is an advanced accelerometr which can detect free-fall,activity,tap,double tap and communicates via I2C. The ADXL is a a ultra-lowpower as it consumes only 25 u...

Latch using JK Flip Flop

In this post we will learn how to use JK flip flop as a latch. i.e. for one pulse, the circuit continues to stay in the ON state until the next pulse. and the circuit continues to be in the OFF state till the next pulse. This can be achieved by using toggle mode in JK flip flop. TRUTH TABLE: IC 7476 J k set ' reset' Q Q' 1 1 1 1 Toggle IC CD4026 J k set reset Q Q' 1 1 0 0 Toggle Note: Set is referred as PRE or preset. Reset is referred as CLR or clear. Refer the Datasheet of the JK flip flop you are using ...
