High quality, digital copies of manuals for obsolete test equipment

Out of date and hard to find technical manuals are our specialty

Welcome to TekWiki, a wiki for the community of Tektronix oscilloscope enthusiasts.

Here at our locally owned, brick-and-mortar business, we strive to create a warm, friendly environment for all of our customers. We always offer free coffee and the full extent of the knowledge to inspire and educate customers so they can see their ideas come to life. We're always more than happy to answer any questions you may have regarding products or the project you're working on. Please stop by in-person to see the perks of buying from a real storefront!

Whether you need parts for work or play, you’ll find what you need at EPO. We deal extensively with basic components, wire, tools, connectors, surplus, project/educational kits, motors, robotics, micro-controllers, and hardware. We have vintage computer equipment, test equipment such as oscilloscopes, meters, power supplies and more! From typewriters to vintage film projectors and cameras we have it all.

We are a Dutch company and love exotic and obsolete electronics.
We service a global market that urges for vintage high quality products
while cheap inferior Chinese crap is trying to dominate. We only sell parts
from well known manufacturers that comply to specs you would expect
for a affordable price.

We keep our stock up-to-date by acquiring NOS parts out of insolvencies
and overstock. At the moment we have about 40,000 parts in stock within
2,000 product ranges.

SigNoz is an open-source observability platform native to OpenTelemetry with logs, traces and metrics in a single application. An open-source alternative to DataDog, NewRelic, etc. Open source Application Performance Monitoring (APM) & Observability tool

In this post I want to give some love to an open-source project that I have discovered just a few months ago: SigNoz.

[Heath Paddock] wanted to confound his friends with a game that mimics an escape room in a box. About six months after starting, he had this glorious thing completed. It’s a hardware version of a game called Keep Talking and Nobody Explodes where players have five minutes to defuse a suitcase bomb. This implementation requires at least two players, one with the box-bomb itself, and one who holds all the knowledge but can’t see the box-bomb to defuse it.

There are plenty of hobbies around with huge price tags, and ham radio can certainly be one of them. Experienced hams might have radios that cost thousands of dollars, with huge, steerable antennas on masts that can be similarly priced. But there’s also a side to the hobby that throws all of this out of the window in favor of the simplest, lowest-cost radios and antennas that still can get the job done. Software-defined radio (SDR) turned this practice up to 11 as well, and this radio module uses almost nothing more than a microcontroller to get on the air.

The design uses the capabilities of the Raspberry Pi Pico to handle almost all of the radio’s capabilities. The RF oscillator is driven by one of the Pico’s programmable I/O (PIO) pins, which takes some load off of the processor. For AM and SSB, where amplitude needs to be controlled as well, a PWM signal is generated on another PIO which is then mixed with the RF oscillator using an analog multiplexer. The design also includes a microphone with a preamplifier which can be fed into a third PIO; alternatively it can receive audio from a computer via the USB interface. More processor resources are needed when generating phase-modulated signals like RF, but the Pico is still quite capable of doing all of these tasks without jitter larger than a clock cycle.

Stream-Pi runs on multiple platforms; Windows, MacOS, Android, iOS and Linux. This also includes ARM Systems like Raspberry Pi.
