RFID im Gesundheitswesen – dies sind die Vor- und Nachteile

Tracking mit RFID ist mittlerweile auch im Gesundheitswesen ein Modewort geworden. Immer mehr Krankenhäuser setzen auf diese Innovation, die viel Geld und noch mehr Arbeit ersparen soll. Bekanntlich ist aber nicht alles Gold, was glänzt, was auch für RFID im Gesundheitswesen gilt. Unbestritten ist, dass die RFID-Technologie vor allem in Krankenhäusern viele Vorteile hat, aber […]

App note: Linear motion potentiometers

App note from Bourns on linear motion potentiometers and how they can be used to detect position by voltage division ratio. Link here (PDF)

The elements of the LMPs are manufactured with conductive plastic (CP) for extended wear capabilities. Unlike Trimmers, which are “set and forget,” these devices are designed to monitor position and are thereby designed to have a very high cycle life capability. LMPs are ideal for converting a mechanical linear motion displacement into a proportional voltage output when used as a sensor.

In defence of the Iklectik Art Lab

The Iklectik Art Lab is at risk of eviction from Old Paradise Yard. We talk to Tom Fox from Hackoustic to hear what can be done to save this iconic music and arts centre.

My learning journey with Music Hackspace

This post is about my learning journey over the past 1 – 2 years – how I came to Music Hackspace and what it came to mean for me. I’m …

Free Stuff - September 2023

The September recipient for the Great Scott Gadgets Free Stuff Program is Erik. Erik is an Ojibwe filmmaker and artist. He has only had his amateur radio license for a short while but he is already assisting in running community demonstrations on how amateur radio can help in emergency situations. We are sending Erik a HackRF One so he can build a mobile training station and take his emergency preparedness demonstrations on the road to Native communities. As an avid camper and road tripper, Erik is also excited to eventually take his demonstrations into wilderness settings and rural communities. We...

App note: How Silicon Carbide power schottky diode properties provide enhanced application capabilities

Great read from Bourns’ white paper about the new SiC Schottky diode which revolutionize power handling capability and other benefits compared to Silicon diodes. Link here (PDF)

For diode applications, the ideal component would be one with no voltage drop during forward conduction and no leakage current when reverse biased. It would change instantly from conducting forward current to blocking reverse voltage. Compared to junction silicon diodes, Schottky diodes provide reduced voltage drop with decreased reverse bias recovery current.
This paper discusses the properties of Schottky diodes constructed using a silicon carbide (SiC) n-epitaxial semiconductor material layer attached to a metal contact...

App note: Trimmers interfacing with surveillance system sensors

App note from Bourns about the robustness of trimmers used on surveillance system, typically sealed to protect agaisnt harsh environment. Link here (PDF)

Trimmer technology is designed for use in applications where the unit must be calibrated before it is shipped to a retailer, and eventually the end user. Typically, these pre-calibrated electronics use a trimmer for required adjustments to account for component variations over time. Medical and industrial designs frequently take advantage of the system calibration convenience of a trimmer. In surveillance systems, the trimmer is adjusted to obtain the best resolution of the sensors at an
installation point.

App note: Basics of linear fixed resistors

App note from Vishay going back to the fundamentals of humble fixed resistors. Link here (PDF)

In the shadow of microelectronics, passive components such as discrete resistors would seem to have fallen out of the field of view in electronics. Yet, it is the rare circuit that can do without resistors. And a look at a modern circuit board will show that it has become more difficult to locate them visually.
