No Moving Parts HMI – The Essential Device for Industrial Environment

The technology is getting better and better every day. Now, there are many industrial have been using the No Moving Parts HMI to help them detects the effects of the human operators’ hands on eight input devices. Honestly, the No Moving Parts HMI (Human-machine interface) is equipped with the high tech MC33794 e-field sensor, which is often being used in many electronics project that involved sensors on it! Technically, the input devices are fully-designed around electrodes to produce responses to human interaction, in either digital or analog form. The HMI is normally had two analog speed control inputs and six digital switches. Three of the digital switches are attached on each side of the two axes. In this case, it can be used to perform the motion control, including of Forward, Reserve and Maintain Speed. Honestly, the great part of the MC33794 is the repeatability of the signals, which is produced by the electrodes. Hence, once an input device is calibrated, the inactivated and activated signals can be easily interpreted by software! In addition, the calibration are going to be… Continue reading

Antitheft Suitcase – You Won’t Be the Target of The Thieves Again!

You want to keep the important things in the suitcase, but you’re afraid that you’ll become the target of the thieves? Well, if you have plenty of money, then you might didn’t mind to buy a high end suitcase. Or, you might want to spend a few hours to modify and create your very own sophisticated “Antitheft Suitcase”! Honestly, the concept of this antitheft suitcase is derived from the security briefcase used by jewelry. In this project, a piece of metal foil under the handle needs to be connected to an MC33794 e-field sensor. This step is to sense when someone is carrying the briefcase with or without permission. In addition, three metal tabs are used to connect to other three e-field electrodes, which are serving as keypads to enter the arm or disarm codes. Normally, by only using a proximity electrode, the device can sense the suitcase distance from its owner. Furthermore, the MC68HC908 microcontroller-based system is included into the project. Its main purpose is to sound a buzzer alarm to alert the owner, if the stranger is picking… Continue reading

The Backpacker’s Treasure – Backpack Water Level Monitor

People enjoy different types of activities in their free time. Some love to spend their time on the indoor activities, while other might find outdoor sports are more thrilling and exciting! If you’re one of those that enjoyed the outdoor activities, then you should keep yourself prepare with this backpack water level monitor! For the extreme hikers, they have to face many possibilities during the hiking expedition.

Hence, it’s extremely important to bring an ample water supply in a backpack. However, the hikers always faced the difficulty, where they didn’t know how much water is left inside the backpack’s bottles! Well, thanks to the advent technology, now the backpack water level monitor can be your personal assistance. The main purpose of it is to gauge the water level in backpack, where the monitor is regularly measures the water level and display it when the user presses the button! Beside that,… Continue reading
