The Smart SD Card Bathroom Scale

  By

Are you always having trouble of weighing your weight, especially when you’re on the bathroom? If this problem has been bothering you for a very long time, then this smart SD card bathroom scale would be the best solution for you! For today’s project, we’re going to learn on how to hack a digital bathroom scale, so that you can write (log) your weight variations over time on a memory SD card. It might sound a little bit complicated here, but honestly, it wasn’t as hard as you thought in the first place. Basically, the theory is very simple and work perfectly for everyone. If you would like to have the bathroom scale sending by wireless the weight values, then you should apply a display console (running embedded GNU/linux) and attach it to bathroom wall. The wireless signal would be received and a graph will be shown to the user with last values of the last two weeks. As a result, it’s a best method to let the user have a clear picture about their weight progression from time to… Continue reading

Dual Axis Level Sensor – The Perfect Application for Home or Industrial

  By

Most of the time, we’re have been experiencing this awful situation before. Go figure, how many times you’ve tried to adjust something for level with a spanner, but you’re not able to see how you doing! Furthermore, things start to out of control, if you are handling a pool table that has four adjustable feet, which you can fiddling around with the spanner and trying to figure out what is the exact table level is! Yeah, the whole scene could turn into a really nasty and huge pain for the fixer… However, there’s better solution for the above matter. Let’s meet the Mr. Incredible, Dual-Axis Level Sensor (Oops, is it really a person?). Basically, the dual-axis level sensor is based on LPC2138 microcontroller. Even though the designation is quite simple and unattractive, but it provides exceptional convenience to the users! For your information, the sensor system is fully-designed around electrolytic tilt sensors, where is capable of providing precise positioning measurements in within a few seconds! The units form the basis for many other applications. The Dual-axis level sensor is including… Continue reading

DIY Wireless Keylogger is as easy as ABC!

  By

As the internet users, do you know what the most dangerous parts are? Well, some of you might say, “It would be the nasty computer viruses or malware”. However, most of them neglected another important factor here: Being the victim of the keyloggers! Oh, for those of you that didn’t know the meaning of “Keylogger”, it’s refer as “Keystroke logging”, which is the practice of logging the keys struck on a keyboard, typically in a sneaky manner. In this case, the person who uses the keyboard is unaware that their actions are being monitored or manipulated by the keyloggers! If you want to know how the keyloggers monitoring someone with his/her keyboard, then it’s very important for you to know the basic of DIY your own wireless keylogger! Basically, most of the keyloggers starting their DIY with the hardware part. So, a hardware keylogger is a perfect solution for monitoring user activity at a very low risk of disclosure. For your information, hardware keylogger is normally a purely electronic device. Due to this feature, no access to the operating system… Continue reading

TV-based Oscilloscope – The LPC2138 Microcontroller-based Device

  By

Many home hobbyists like to try something interesting and different. If you’re one of them that love to take on a challenge, then it’s the perfect time to get into this TV-based Oscilloscope projet! Hold on a minute! You’re thinking, “TV-based Oscilloscope? I’ve done the similar project before and I don’t want to waste my time on this stuff again!” Come on, guys. This TV-based Oscilloscope is slightly different from the others, as it based on a LPC2138 microcontroller application. It can be used to convert a standard television into a high-functioning oscilloscope. This means, with only a single chip solution, it able to turn your TV into a digital storage oscilloscope with a sampling rate 160 Ksps. This feature allows you to monitor five different voltages on the five analog inputs simultaneously! The main purpose of the project is to implement a high-resolution video generator inside the ARM microcontroller, LPC2318. In this case, the video generator is able to operate in the background mode, even though with a very low CPU loading! It supports two different standards, American NTSC… Continue reading

Buckymeter – The Best Buddy for Professional Bull Riders!

  By

Is anyone here ever watched the “America’s Toughest Jobs”? Did you know that the bull riders are amongst the top 10 jobs in America? Also, it’s one of the most dangerous and brutal job, as you might twist your ankle or probably get yourself killed, during the bull riding event! Even though the annual salary of Bull rider is not too high, which is measly around US$42,000, but there are still many youngsters interested with this job! If you’re happened to be a bull rider, then this Buckymeter might be the ideal device for you here! Basically, Buckymeter is a tool, which is based on MEMS sensors and an LPC2138 microcontroller. For your information, the Buckymeter is also known as “Precision motion-sensing system” and it’s only being used in the military and commercial aviation in the last few decades! Thanks to the advent technology, a collection of these sensors can be connected to a custom microcontroller easily. This makes the MEMS sensors as one of the most high-end sensors in the electronics world. Well, the Buckymeter might be a small,… Continue reading

The Remarkable Measurement Computer of Nuclear Weighing System for Conveyors

  By

Human beings are capable of doing many things in their life. Sometimes, we still need the help from the computer to perform some tasks that require high accuracy and precision! For an example, it’s impossible for use to carry out the nuclear weighing tests all by ourselves, unless we have a Measurement Computer of Nuclear Weighing System for Conveyors. Technically, the measurement computer of nuclear weighing system for conveyors is a complicated process computer of digital processing to process measurements. For building this project, you’ll need the following components: An LPC2132 microcontroller, A Sealed radioactive source, A detector, An LCD, A power supply. You can use the nuclear weighing system to provide a non-contact method of measurement of materials on a conveyor belt, and screw conveyor system. Honestly, many Measurement Computers had been installed at Industrial field. The main purpose of the installation is to process the signal coming from the detector of Nuclear Weighing System. In addition, you can use the Measurement Computer to perform these tasks: Processes the signal, Display the data, Output the standard signal (4-20mA) to… Continue reading
