PC Automated Pressure Measurements

Pressure Cooker

Pressure Cooker

One of the vivid memories from my childhood is working in the garden picking vegetables. We lived on a farm and it was common to have a big garden. My mother would can all types of food, such as tomatoes, pickles and green beans. Part of this canning process involved boiling the jars of food in a pressure cooker. The release valve, with its hot hissing steam escaping, always intrigued me.

Canning food in the kitchen is a relatively simple process and easily controlled by the cook, but there are many other applications where it makes sense to automate the process. (more…)

Between Mac and PC: The Expert I/O API

Mac vs PC

Mac vs PC

PC based automation doesn’t need to be difficult. Some application user interfaces are terribly complicated and take forever to learn. Often, even the simple interfaces prove difficult because they make some features impossible to use so that other features are simple.

I see this all the time in products. The Mac vs PC battle (which is really Apple vs Microsoft) is a perfect example. (more…)

GPS, Trade Shows and PC Based Automation

Rosemont, IL

We made the trip to Chicago (Rosemont) last week to visit the Design & Manufacturing Midwest show. I did my due diligence the night before and printed directions and maps which looked fairly straight forward. Up I-65 to I-94 to I-294 and exit on River Rd. right at the convention center.

Unfortunately, I was distracted with the frequent toll stops and road construction. When I started seeing signs for Milwaukee, I began to worry. (more…)

2009 Golden Mousetrap Finalist

2009 Golden Mousetrap Finalist

Earlier this year, we entered the Expert I/O 1000 in the 2009 Design News Golden Mousetrap contest. Today, we are proud to announce that it was selected as a finalist in the Test & Measurement category. It’s a great honor to be standing shoulder to shoulder with the likes of Agilent, National Instruments and ABB who also attained top positions in the same category.

For more than two decades, the Design News Awards Program has recognized engineering innovation and creativity in product design. This year, Golden Mousetrap awards were given in four major categories: Electronics, Motion Control/Automation, Hardware/Software, Materials/Fastening/Joining/Assembly, and 20 subcategories. Design News gathered a record number of entries, distributing them to their beat editors for judging. Based on the editors’ expertise in each technology area, 71 finalists and 23 winners were selected. (more…)

Design World August 2009

Design World August 2009

Dajac recently published a press release describing the Expert I/O 1000. As has been the case time and again, we received a very positive response. It was published on no less than 13 technical magazine web sites (listed below) and this month, it was included in print for the first time. The August 2009 edition of Design World magazine gave it more than a fourth of a page!

To celebrate this milestone, we are offering special pricing for a limited time. Mention Design World magazine during your Expert I/O 1000 purchase and receive a 25% discount. You’ll have to act quick. This offer only lasts through September 8th, 2009. (more…)

TIED IN KNOTS – A Must-Have Guide to Untangling USB Extension Options for PC Based Automation

Understand Your Options

Understand Your Options

Stop Your USB Devices From Being Shackled to a PC Like the Pretty Boy on a Chain Gang (He Can't Wait to Get Free!)

Most people believe USB connections are constrained to 5 meters from the PC. In PC based automation projects they toil with PC and device placement.

It's never been easier to free yourself from this restriction. (more…)

Links to USB Extension Products

Wednesday, August 19th, 2009

In TIED IN KNOTS – A Must-Have Guide to Untangling USB Extension Options for PC Based Automation, I discussed several methods for extending the USB connection between the computer and the device. While these solutions exist, not all of them are easy to find. Here are a few product links for each solution. (more…)

Understanding Expert I/O 1000 Access Times

Expert I/O Timing

Expert I/O Timing

I often get questions about the Expert I/O 1000’s access time characteristics. The short answer is that you can change outputs at a rate of 100Hz and you can read inputs at 50Hz. However, the complete answer is more complicated.

When dealing with MS Windows on a PC, it’s not possible to get absolute realtime results. You will always have some variability in timing. However, Dajac’s USB implementation directly associates the timing to guaranteed values in the USB specification. Therefore, we know the guaranteed worst case access times at the USB level. (more…)

Single-IC USB isolation.

Single-IC USB isolation.

Worried about using USB connected devices because they lack electrical isolation? Worry no more. Your life is about to get incredibly simpler. Analog Devices has answered your prayers with their new iCoupler ADuM4160 single chip USB isolation solution. Combine it with the ADuM5000 and isolate the power as well.

The ADuM4160 is the industry’s first single-IC USB isolator that meets medical and industrial standards while replacing complex board level solutions. The ADuM4160 offers 5kV rms medical-grade isolation as well as upstream short-circuit protection. (more…)

David Novak, Owner and Engineer

Hi, I’m David Novak, owner of Dajac Inc. I want to take a few moments to introduce myself and tell you about Dajac. I graduated from Kansas State University with a BSEE degree in 1993 and continued at KSU in a masters program the following semester. In 1994, I graduated with a MSEE degree. During my masters work, I specialized in machine vision and image processing. This was put to good use when I went to work for Hopkins Manufacturing. (more…)
