- Comment on Looking for replacement Nixie tubes 5 days ago:
You can create a saved search on ebay, wait and hope some eventually show up. They won’t be cheap though.
- Comment on Email ownership, I give up. 1 week ago:
It’s not really worth the trouble to try to host your own e-mail. There are lots of e-mail hosts that you can use with your own domain. A few of them are free and there are plenty of low cost ones. As long as you use your own domain, you can switch hosts whenever you want and keep your addresses.
- Comment on What are your self–hosted alternatives for inter device communication? 1 week ago:
Syncthing and Nextcloud are both FOSS. You don’t need to sign up for anything.
- Comment on Why don't people with resin printers use acetone/nail polish remover more often for cleaning their prints? 1 week ago:
The denatured alcohol you typically find in the the US contains a lot of methanol. It’s much more toxic than IPA.
- Comment on Tuning in FM Radio on a 3D Printer Heatbed 2 weeks ago:
FM radio stations can transmit up to 100 kW. You can probably receive some just by sticking a paper clip in the antenna jack even if you are a long ways from the transmitter.
- Comment on Better filament than ABS 3 weeks ago:
PETG works great as long as the part doesn’t need to handle more than 60°C. It’s easy to print with and doesn’t warp.
I would not recommend using PETG-CF though. It will shed microscopic fibers unless you coat it in varnish or epoxy.
- Comment on Magnetic bass detection? 4 weeks ago:
Reed switches aren’t that sensitive. The magnet usually has to be within a centimeter or so from the switch to operate it.
- Comment on Drilling and tapping LiFePO4 battery terminal practicality? 1 month ago:
It can be done, but I would suggest doing it outside to be safe. Set the depth stop on your drill press so you can’t go too deep.
You will need a normal tap to get started and a bottoming tap to finish threading the hole all the way to the bottom. 5mm is not a lot of thread to work with in soft aluminum. Those terminals are intended to have bus bars laser welded to them.
- Comment on Sniffing WS2812 (Neopixel) bus? 2 months ago:
With a 24MHz sample rate, there will be 30 samples per bit. The narrowest a pulse for the WS2812 can be is 220 ns, which will be about 5 samples. That’s more than enough to decode it.
- Comment on Sniffing WS2812 (Neopixel) bus? 2 months ago:
The WS2812 only runs at 800kbps. That’s well within the capabilities of one of those 24 MHz FX2 based USB logic analyzers that you can get for less than $10. Sigrok has a protocol decoder for the WS2812 LEDs.
- Comment on Not sure if this is the right place to ask, but does anyone know if I put a wifi extender in the shed (according to the drawing) will the signal reach the office? Thanks for any help. 2 months ago:
I would just get some direct burial ethernet cable, drill a couple of holes and install an access point in the office. WiFi repeaters can be unreliable, especially if there are already a lot of WiFi networks in your area.

Those will jam radio reception for your whole neighborhood. They should be illegal.
- Comment on 4 channel scopes, budget. Siglent or Rigol? 2 months ago:
I’ve got a Rigol DS-1054 and the serial decoding is terrible. It can capture 24 million sample points, but it will only decode from the few hundred points that are displayed on the screen. That means it will only decode a few bytes of data. I don’t know if any of their newer models have gotten any better.
Definitely get a 4 channel scope. The extra channels will come in handy even if you think you don’t need them. The digital channels tend to be less useful. The 16 channels you get on a scope are not enough to probe a parallel bus, but way more than you need for serial. I would rather use a USB logic analyzer. It’s easier to work on a PC with a big monitor and the ability to write your own protocol decoders if needed.
- Comment on Plex’s crackdown on free remote streaming access starts this week - Ars Technica 6 months ago:
Jellyfin is free open source software, they don’t have the money to provide free proxies to their users.

- Comment on 18% of people running Nextcloud don't know what database they are using 9 months ago:
FAT32 is still a very common filesystem for flash drives and memory cards because it works on everything. Lots of people are likely to run into the 4GB file size limit.
- Comment on need help on old CRT tv 9 months ago:
Some old tvs and depending on the electrical circuit they are plugged in dont like when high powered devices are running.
It's not really an issue with high powered devices, it's an issue with brushed motors that arc and produce loads of RFI.
- Comment on I had no idea it was possible to create a working floppy disk from scratch, and neither did this YouTuber until they broke out their engineering chops 9 months ago:
It didn't work though. He wasn't able to actually store any useful data on it.
- Comment on Trump cuts funding to FOSS projects. 1 year ago:
HTTP works fine in Firefox unless you set it to HTTPS only. Even then, you only have to click off a warning to open an HTTP site.
