Semiconductor test equipment (IC tester), or automated test equipment (ATE), is a system for giving electrical signals to a semiconductor device to compare output signals against expected values for the purpose of testing if the device works as specified in its design specifications. IC Testers are devices which are used to test Integrated Circuits by →
Did you know than an audio equipment can cause “off gear distortion” on line level signals that are driving multiple pieces of audio gear? I have had situation where I had one CD player wired to inputs of two different amplifiers (Y-splitter cable). When both amplifiers were powered on, everything worked nicely. But when one →
Now that’s two shots on the ARM processors. NVIDIA and SoftBank Group Announce Termination of NVIDIA’s Acquisition of Arm Limited. NVIDIA has announced it is dropping its plan to acquire Arm, walking away from a deal originally valued at $40 billion in stocks and shares — with the Cambridge-based company set to go public under →
Hackaday has spent several months in this series journeying through the world of audio. Now it’s time to descend into one of the simplest yet most controversial areas of audio reproduction. Every audio component, whether digital or analogue, must be connected into whatever system it is part of, and this is the job of audio →
While the world’s chip shortage dominated the 2021 headlines, the semiconductor industry blazed new trails with the increased electrification of cars, focused AI applications, improving power/performance, better utilization of data deluges, dealing with design challenges in advanced nodes and much more focus on chip security. Semiconductor Engineering’s Tech Talks reflected these focus areas. Semiconductor Engineering’s →
Transformerless power supplies are showing up a lot, especially in inexpensive products where the cost of a transformer would add significantly to the BOM. But transformerless power supplies are a double-edged sword. You can get yourself easily electrocuted if you don’t understand them and take proper safety precautions. Poking around in a transformerless-powered device can →
The Pinouts Book Is Here, And It’s Just What You Need. The Pinouts Book project has published the free PDF download “book” that contains over 300 pages of hardware diagrams and their respective pinouts. This is a work of hacker minimalism at its best. THE PINOUTS BOOK is available a PINOUTS.ORG The Pinouts Book is →
By far the most used oscilloscope probes are the passive 10:1 attenuation probe. Next step in probe categories are active probes. Active probes succeed in practically eliminating reactive loading of the circuit under investigation by means of a small solid-state amplifier in the probe body adjacent to the tip. There are two main classes of →
Smoke and fire alarms can save lives. The occupant and the housing company are responsible for the acquisition and maintenance of smoke alarms in Finland. It is the duty of the occupant of the flat, i.e. the resident, to buy a smoke alarm and to keep it in good working order. Smoke alarms must meet →
I got some TAIYO YUDEN 9012R0 LEADED COMMON MODE CHOKE COILS FOR AC LINES and thought some uses for them. The specifications for those from datasheet were: TLH10UA 901 2R0 RoHS Common mode inductance (mH): 0.9 min. Normal mode inductance (mH): 0.067 DC resistance: 0.089 Rated current (A max): 2.0 Rated voltage AC (V max): →
