The model N2802A offers 25GHz of analog bandwidth, 17.5pS of rise time and a total differential input capacitance of 32fF at 10k-Ohm […]

Simplify Eagle library part creation from BSDL files

Here’s a tutorial on how to automatically generate Eagle parts from manufacturers’ BSDL files. These files are available from some manufacturers and include tables listing pin names and numbers. This information is used by the make-symbol-device-package-bsdl.ulp to generate your device. On our wiki we have a tutorial on how to built devices for your Eagle […]

Hak8or’s scavenge of electronic parts from old computer hardware

Got an old computer collecting dust? Break out the hot air, and start scavenging for electronics gold. This is just what Hak8or did over the weekend. He took components form an old motherboard, and a SCSI PCI card. For a detailed component by component breakdown of his score check out his blog. I wanted to […]

7 segment display controlled by simple SPI interface

Touch let us know about these 4 digit SPI controlled 7 segment displays that cost a little less then $1 a piece. They include decimal separators and a colon separator so it’s easy to display time. I picked up some cheap 4 digit 7 segment displays over on eBay for $10 + shipping. They Include […]

Component Organizer source code released

A while back we posted about an app, Component Organizer, that helps you organize datasheets, and app notes connected to various parts you may be interested in. Yesterday Msr let us know that he has released the source code. You can download it at github. He also added a tutorial to help contributors get started. […]

HOW-TO: Create Eagle parts with pins that have the same name

Most chips have multiple power pins that need to be connected to the same power supply, but Eagle doesn’t allow you to give 2 different pins the same name. This short tutorial shows how to get around this and name multiple part pins the same thing. Keep reading below, see our other Eagle tutorials here.

Ceramic, tantalum, and electrolytic capacitor comparison

Arhi made use of his precision LCR meter to measure capacitance and ESR values of ceramic, tantalum, and electrolytic capacitors. He made his measurements at various frequencies to help him graph the changes to the values over a wide frequency range. From the graph it can be extrapolated that the ceramic capacitors have the lowest […]

Sjaak’s shop-a-holic trip to Akihabara Electric Town

Sjaak stayed a little bit longer in Tokyo and had more time to score some nice parts. As we already said the big plus of shopping in Akihabara is you can actually touch the stuff, but it also has a major downside – you buy too much stuff… Please continue reading about our shop-a-holic trip to […]
