As someone with some EtherCat and CNC experience, what’s your interface from gcode to your CNC? Have you written custom software or is there a EtherCat compatible gcode sender I’m unaware of?

They ground up rebuilt it a while back and it seems like they’ve fixed that issue.

The Cypress part family you are likely thinking of is the PSoC line, it’s a MCU mixed with very configurable analog front end.

I’ve been very happy with my Siglent 4 channel/100 MHz scope (with logic analyzer but I don’t have the $200 pod so I don’t use that). The scope was about $400 and I find it worth the investment. It’s on the same level as the popular Ri

From my research into microscopes for fine electronics work, the keyword you are looking for is “trinocular”. They have standard camera mounts built in and you can attach almost any camera via an adapter.

Did anyone else play Mavis Beacon growing up? I recently got a mechanical keyboard and there’s an online version of Mavis Beacon that held up surprisingly well, and got me used to typing on the new layout.

The only roadblock I’ve found has been the webserial API, which enables users to flash ESP32/8266 or other devices from webpages. It’s super handy for flashing WLED or ESPHome to devices because you don’t have to install any extra soft

Honestly, I don’t consider this mindless piracy. It’s ridiculous how many links on HN are behind a paywall. I understand the press needs to be funded, but I do not regularly read NYTimes or the many other news sources locked behind a paywal

Tkinter is fairly basic but feels very native on every platform I’ve tried, and it’s easy to use. There are lots of extensions available too. I just wrote a comment about it: If you’re interested in Python desktop apps, check out TKinter. I

If you’re interested in Python desktop apps, check out TKinter. I have a piece of boilerplate code I typically start with, and within an hour I can have a finished piece of software that runs in the native windows manager on any OS with no

I suppose old hardware restoration falls under the “hobbyist” label?

FYI, there is a Home Assistant integration for the WiZ bulbs that I find works really well… I almost exclusively control my 6 or so via HomeKit and they have been rock solid.

This looks cool, but your link is to a video describing it, and the app “Object Capture” doesn’t appear to be in the Apple App Store.

I signed up for a one year Nebula subscription after one of my favorite YouTubers posted a discount link. I wanted to support him, and I found the price to be fair. In the few months I’ve been subscribed, I’ve found that the library is much

24 VAC is a common voltage for irrigation control, which is likely why they chose to use it.

Even this appears to just be a limited source repo containing just the most basic UI components. Also, per the README: > Please note that LX Studio is not open-source software.

Would love to see more open source competitors in this space. I was excited when I saw a Github link, but that's basically hosting just a README and the only one I know of is GeoPix [0], but to be fair I haven't used either LX Stu

> And... AVR64DB32 is cheaper at Digikey than ATMega328pb. Sure, you save about $0.80 off your BOM, but currently DigiKey has a stock of over 200k ATMEGA328P (in 31 P/N), whereas searching for any of the AVR64DB32 family (of which t

Those WiZ bulbs have actually been pretty reliable for me in the few years I’ve had them. Pretty early on I set them up to be controlled by Home Assistant [1], and they are on par with my other Hue devices in terms of performance (maybe not

Another huge aspect is the CRI/CQS of your light sources. CRI (Color Rendering Index) and CQS (Color Quality Scale) try to quantify how faithfully colors are represented when a subject is lit. Generally a higher CRI equals a higher qua

@theacodes- I'm blown away by the awesome inline KiCad visualizations. Did you use any tooling for capturing the layout view so the layers could be overlapped so easily? Any thoughts on making a library for this so others can build sit

How is it not open source? The very first download link is to download the source. And it’s GPLv2 licensed.

I’ve still got my copy… interestingly enough though, it appears as several volumes now, of which only the first is free. The others are $9.99. IIRC it used to only be one book.
