Metcal’s CV-5200 Connection Validation Soldering Station Changes Everything

You may or may not have heard about Metcal’s new soldering station, the CV-5200. The evolutionary tool removes much of the reliance on visual inspection of hand-soldered joints and adds a second, more technology-driven method for validating a successful Read more

LEDs in the Extreme: How to Keep Them Lit Regardless of Environment

LEDs in the Extreme--How to Keep Them Lit Regardless of EnvironmentRain and wind. Extreme heat, moisture and more—LEDs need to work properly regardless of the elements. While adhesives have been perceived as slow and expensive assembly methods, the correct LED adhesive for harsh environments not only expedites the manufacturing process but also perfects it.

Adhesives perform well on glass, metal, ceramic and most plastic substrates. They provide excellent chemical and solvent resistance, serve as insulators and can be used in high-speed production environments. And, when it comes to LED assembly, these benefits are critical. In some cases, choosing the right adhesive for the job at hand also means cost-effective production that would have been impossible with mechanical fasteners.

For every type of LED package, from circuit board mounting to completed luminaires, adhesives and sealants play an important role, including long-term protection from vibration and shock. If you’re operating in an extreme environment, explore modern LED adhesives and sealants, like those from Henkel Loctite®, that perform over a long range of temperatures and provide excellent chemical, humidity and UV resistance.

The Changing Face of ESD Control: Have You Done Your Due Diligence?

The Changing Face of ESD Control--Have You Done Your Due DiligenceEnsuring compliance to ESD requirements and standards presents challenges, especially in light of recent ESD Association changes. Depending on your workplace or environment, improper ESD control can cause fires or explosions resulting in costly damage and injuries. For these reasons, maintaining compliance, and ensuring your program’s efficacy, requires due diligence, including the careful selection of all appropriate instrumentation and other equipment.

Selecting the right equipment for the job at hand is paramount. Desco’s ESD control products are designed to help you maintain compliance with your organization’s ESD program, the basic tenets of which likely include the following:

  1. All conductors of electricity should be grounded to ensure an equipotential balance of electrical charge at all times in protected areas.
  2. Ionized-air sources should be provided to neutralize electrostatic charge on the necessary nonconductors in protected areas.
  3. Appropriate static control packaging or containment for protection of sensitive items should be used when the items are removed from protected areas.

ESD control products from SCS, on the other hand, are primarily comprised of testing and measurement equipment, so you can verify your program is working properly. When used in conjunction, Desco and SCS brand products help to create fail-safe methodologies for an efficient and safe ESD program in any environment.

New Chicken Feathers Reactor Garners Reaction

New Chicken Feathers Reactor Garners ReactionTwo teenagers from Bosnia and Herzegovina have built a reactor—from chicken feathers. Ubiquitous and far less expensive than carbon nanotubes, chicken feathers have already been used to store hydrogen and produce biodiesel. Their reactor, which combines these discoveries, earned the teens a finalist spot at the Google Science Fair in Mountain View, CA last week. Weeding out thousands of submissions, the system produces both biodiesel and carbonized chicken feathers.

Carbonized chicken feathers can store hydrogen at least as well as carbon nanotubes, but presents an affordable option. A 20-gallon carbon nanotube tank costs $5.5 million to make; whereas chicken feathers can be used to store the same amount for $200.

Hydrogen is used extensively in the production of ammonia, methanol, gasoline, heating oil and rocket fuel. It is also used to make fertilizers, glass, refined metals, vitamins, cosmetics, semi-conductor circuits, soaps, lubricants, cleaners, and even margarine and peanut butter.

New Device Converts Light to DC Current

Posted on by Kathy S. in Green Initiative Leave a comment

New Device Converts Light to DC CurrentEngineers at Georgia Institute of Technology have demonstrated the first optical rectenna, which combines an antenna and a rectifier diode to convert light into DC current. The device uses carbon nanotubes that act as antennas to capture light from the sun or other sources, creating an oscillating charge. As the charge moves through the attached rectifier devices, the rectifiers switch on and off and create a small direct current.

Advances in fabrication technology have made it possible to capture solar energy in this way. While rectennas have operated at wavelengths as short as ten microns for more than 40 years, this optical rectenna is the first of its kind.

Currently, its efficiency is below one percent, but the researchers predict a greater than 40 percent efficiency in the near future, with commercial potential available within a year.

Is Your Networked Lighting a Security Risk?

Is Your Networked Lighting a Security RiskLightbulb hacking. It might not sound like a real threat, but savvy, networked lighting hackers could gain access to your entire building automation and smart home systems.

The necessity for preventing unwanted access to connected safety and security devices like door locks and security cameras goes without saying; however, any device connected to the network, including a lightbulb or appliance, can serve as a gateway to the system.  Researchers have demonstrated this across multiple brands of lighting products utilizing both WiFi and mesh protocols like Zigbee.

The key to protecting connected devices? Rely on a dedicated, tamper-resistant security device, such as a secure microcontroller that enables secure storage of network passwords and authentication keys.
