Spring-loaded pins are rapidly finding new applications in modular product design. Also referred to as SLCs (spring-loaded connectors), this product resolves many of the manufacturing issues like misalignment, coplanarity, and tolerance stack up that can plague traditional pins and sockets...
In this blog post i will share the OLED libraries with you, which are written for mikroC compiler and can be used with any other C compiler.
Following are the functions which are currently present.
void OLED_Init( void );
uint8_t OLED_Width( void );
uint8_t OLED_Height( void );
void...
The following attached file contains an SSH Client extension
which I made for my own use, but it may also be useful for users of the MIT Application Inventor 2 (AI2) community, or even to the AppyBuilder community (code intrinsically compatible for the last one, but not tested). This is just the...
Find bellow an Android TCP client extension
that implements a very simple socket; note that its operation is performed 'one-shot', which means that only one command is sent ( and its respective response, read ) at a time, and then the socket connection is closed. So, be aware that it is not a...
HSM-20G is one of the most common humidity and Temperature sensor. This sensor is fully analog type. The outputs are analog voltages rather than any digital signal.
The datasheet indicates that the output pins need some extra devices with it. here is the connection diagram:

Ceramics comprise the most widely used non-polarized dielectrics. The reason is they offer attractive combinations of volumetric efficiency, manufacturability, and cost. Some applications -- such as high-frequency RF signal chains and high-precision measurement circuits...

Electromagnetic interference (EMI) can create serious issues for manufacturers in an industrial environment. A buck converter generates a pulsating ripple current with high di/dt at the input. Without input capacitors, ripple current is supplied by the upper power source...
Lot of people who start with HFSS have issues in making the complicated geometry in HFSS. Here are very simple steps which anyone can follow to make a 3D structure in HFSS
Just take example of this cavity with attached beam pipes
Step 1 Draw this 3D structure on paper as 2D line Diagram...
In this blog post i will share my Graphical Lcd libraries with you which are written for xc8 compiler in MPLAB-X development environment.
The libraries functions are inspired from mikroC functions and i tried to keep most of the functions similar to the one available in mikroC compiler.

While I was home this winter, I saw that the remote for our TV tuner was damaged physically, causing the buttons to not function responsively. Some of them just didn't work. I saw this as an opportunity for a fun couple days' project to build a new remote controller for the tuner.
The TV...
The Intel Edison test board, along with the USB mouse
I have recently been using the Intel Edison for the Cornell robotics project team (which co-hosts the Intel-Cornell Cup USA competition). Building on my previous knowledge of embedded systems, I started learning to use and program on...
Hi friends !
After a long time a came back again ! 8-)
I want to share you some simple literature ( my own handwriting ) about control systems and oscillators but believe me i tried to make it as simple as i think simpler than this is impossible !
Ready ?
Here i share you 16...

This is a method for calculating the Tin/Lead content in any solder containing mainly those two metals. The method uses only a scale to precisely determine the density of the solder and from there knowing the density of the Tin and Lead, to calculate the Tin/Lead ratio.
As you know the best...

Introduction to I/Q signal
As mentioned above, for SSB modulation, in reality, there will be at least three tones in the spectrum.
One is signal(i.e. desired sideband), another is undesired...
I/Q Imbalance
As mentioned above, for SSB modulation, there should be only one desired sideband in the spectrum in theory.
Nevertheless, in reality, there will be at least three tones in the spectrum.
As shown below, one of the three tones is undesired sideband, so-called image ...
Single Sideband Modulation
Conventional double sideband(DSB) modulation can be considered wasteful of power and bandwidth because they contain a carrier signal and two identical sidebands.
Conversely, single sideband(SSB) modulation, as the name implies, uses only one sideband to provide...
We can also analyze it in terms of E/H fields .
As illustrated above, both microstrip line and stripline radiate E-field outside.
Thus, we need ground plane to absorb their E fields.
And larger the ground plane,
lower the ground impedance, more the E-fields that ground plane...
According to my previous experience,
wideband matching from 700 MHz to 2700 MHz (GSM/WCDMA/LTE) can be achieved by mere 3 components.
If the frequency range is 2.4, 2.1, 1.8, 1.6, 0.9 GHz,
and you have 5 components,
just do the wideband matching from 0.9 GHz to 2.4 GHz
To start...
For a Direct-conversion(Zero-IF) receiver, RF signal down converts to BaseBand signal near 0 Hz directly.
Let’s assume there are 2 tones , f1 is interference, f2 is signal, and their frequency are close, i.e. f1 = f2.
If LNA IIP2 is not good enough, f1 and f2 will compose IMD2...

EDAboard's sister publication, designworldonline.com has several "Tips" sections covering a variety of topics from power to microcontrollers to motor control. We'd like to encourage you to check out some of these helpful tips and share them with your colleagues. To get you started, I'll post the...
It is a common concern of technicians to adapt equipment manufactured on countries whose frequency of electric public mains differs from its local, so that a modification becomes necessary, but depending on the size of equipment, the cost of the transformer may be the largest when compared to...
GLCD is one of the most interesting device in electronics works. People working with microcontroller are very interested to work with it. And me? Yes! I’m very much interested to it… I did some works professionally, but I felt that you may need a help to make your own big font work with GLCD...

Generating Sine wave is very demanded job in power electronics field. So do to me too. I read some topics over the internet and found many ways to generate a sine wave. As most of you are really interested in generating sine wave so I’m writing today about it here.
There is some different ways...
Using the PIC32MX250F128B, I decided to make a simple audio player. I wanted to play back good quality audio from a large memory space - a microSD card. So, I made this WAV player that can play back 16-bit 44.1kHz WAV files with 12-bit stereo audio output. Of course that's not all it can play...
With power LED's mounted boards with adequate copper surface or aluminum surface area (~1 sq.in/Watt) cool emission of light can be adapted to almost any fixture with mindful avoidance of glare.

In Part I of this blog, we saw that we can construct two partially correlated signals, x1(t) and x2(t), as:
\[
\; \; \; \; \; \; \; \; \;\; \;\; \; x_1(t) = \sqrt{P_1}s_1(t) \\
\; \; \; \; \; \; \; \; \;\; \;\; \; x_2(t) = \sqrt{P_2}ρ∗s1(t)+√(1−|ρ|2)s2(t)ρ∗s1(t)+(1−|ρ|2)s2(t)
\]
where P1 and...
Note: This blog is split into two parts because edaboard limits the number of pictures and equations per blog. The second part can be found here: [link].
Introduction
It is often useful to be able to generate (real or complex-valued) signals with specific cross-correlations. In the simplest...
I was recently asked how to estimate the frequency of a noisy sine wave over a short capture. In this context, 'short' means the total capture duration relative to the period of the sine wave. So we may have, at most, a few periods of the sine wave (or, at worst, less than one period). Here is...
Coding Spacing is commonly generally defined by the range between data transitions to prevent DC content of data. Bi-Phase which is self -clocking but reliable and used in early Telephony 1.544Mb/s repeaters then tri-level coding was used. Similar starts in ethernet coding were used.

Power measurement methods for RF
**Peak** = instantaneous maximum read with storage memory ( digital or Analog )often measured with Log Amplifiers calibrated in dBm for 50 or 75 Ohms
**Average** = time interval averaged over specified interval
Both above are computed by voltage detection...
Design site has error in the design calculations for RMS >Peak.
In the end the RMS voltage of the transformer should only be slightly more than the LDO Vdc if the optimal parts are selected.
Assuming you want 5V,1A regulated choose LDO regulator with minimum drop otherwise 2.5V typical may...
