[Other] Show HN: Voltpeek – Vim-inspired oscilloscope software This is software for my headless, PC based oscilloscope, which is controlled entirely via commands similar to the Vim text editor. I built this because I liked the idea of headless oscilloscopes; I always have my laptop around when I’m working on electronics anyway, and it’s very convenient to save images of captured waveforms. However, I found the software for off the shelf models to be annoying and cumbersome to work with. In my experience, this holds true both when opening the software and connecting to an attached oscilloscope, and when adjusting the scope settings using menus and buttons. I have also built my own oscilloscope hardware for use with Voltpeek. The specs are nothing to write home about (7.5MHz BW, 62.5MS/s), but they should be adequate for some basic debugging and measurement tasks.

[Other] Show HN: Mathpad – Physical keypad for typing math symbols Here&#x27;s something different than your usual fare: A physical keypad that lets you directly type math!<p>Ever tried typing mathematical equations in your code IDE, email, or on Slack? You might know it can be tricky. Mathpad solves this with dedicated keys for Greek letters, calculus symbols, and more. Press the ∫ key and get ∫, in any application that accepts text. It uses Unicode composition, so it works everywhere: Browsers, chat apps, code editors, Word, you name it. Basically, anywhere you can type text, Mathpad lets you type mathematics.<p>I built Mathpad after getting frustrated with the friction of typing equations in e.g. Word, and what a pain in the ass it was to find the specific symbols I needed. I assumed that a product like Mathpad already existed, but that was not true and I had to build it myself.<p>It turned out to be pretty useful! Three years of solo development later, I&#x27;m launching on Crowd Supply. One of the trickiest parts of this project was finding someone who could manufacture custom keycaps with mathematical symbols. Shoutout to Loic at 3dkeycap.com for making it possible!<p>Fully open source (hardware + software): <a href="https:&#x2F;&#x2F;github.com&#x2F;Summa-Cogni&#x2F;Mathpad">https:&#x2F;&#x2F;github.com&#x2F;Summa-Cogni&#x2F;Mathpad</a> Campaign: <a href="https:&#x2F;&#x2F;www.crowdsupply.com&#x2F;summa-cogni&#x2F;mathpad" rel="nofollow">https:&#x2F;&#x2F;www.crowdsupply.com&#x2F;summa-cogni&#x2F;mathpad</a> Project log: <a href="https:&#x2F;&#x2F;hackaday.io&#x2F;project&#x2F;186205-mathpad-the-math-keypad" rel="nofollow">https:&#x2F;&#x2F;hackaday.io&#x2F;project&#x2F;186205-mathpad-the-math-keypad</a>

[Other] Show HN: NaturalCron – Human-Readable Scheduling for .NET (With Fluent Builder) Hi HN!<p>I built NaturalCron because I was tired of writing and debugging CRON syntax like:<p><i>&#x2F;5 </i> * * 5<p>Now you can write something human-readable in .NET:<p>var expression = new NaturalCronExpression(&quot;every 5 minutes on friday&quot;);<p>Or use a Fluent Builder for strong typing and IDE support:<p>var expression = NaturalCronExpressionBuilder .Every().Minutes(5) .On(DayOfWeek.Friday) .Build();<p>Great for: - Code-based scheduling in .NET apps - Overriding schedules from configs or databases - Displaying easy-to-read rules in UIs<p>NuGet: <a href="https:&#x2F;&#x2F;www.nuget.org&#x2F;packages&#x2F;NaturalCron" rel="nofollow">https:&#x2F;&#x2F;www.nuget.org&#x2F;packages&#x2F;NaturalCron</a> GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;hugoj0s3&#x2F;NaturalCron">https:&#x2F;&#x2F;github.com&#x2F;hugoj0s3&#x2F;NaturalCron</a><p>Would love your feedback on syntax, builder design, and what features you&#x27;d like to see next!
