@forty2@oldbytes.space Sorry to see that… I adopted a process of always wearing leather gloves while working with ANY power tools (especially drills). This has certainly saved me several times. Also, I have some dull bits that I use (by hand) to take the burrs/edges off of freshly drilled holes. Can make a countersink in acrylic by hand with a little time and patience. Hope your project turns out well! (And fingers heal soonest!) #ClampDownWork #WearGloves #SafetyFirst

@NH6SP@mastodon.radio HOA antenna countdown: Have HOA restrictions here and likely at future house. Having some success with indoor CHA Floop-3 magnetic loop and planning gutter antenna at next house. Gutters worked pretty well at past QTH! Hope you find a workable stealth solution! 73 #HamRadio https://qsl.net/n8dmt/amateur-radio/index.html

@BoscoLab@social.tchncs.de @marcoreps@bird.makeup Have seen similar in lab (but to a lesser degree). Have you sampled and looked at the distribution? Have used LabVIEW in past to sample and gain insight into these types of measurement challenges. #TestEquipment #LabVIEW #MeasurementNoise

@tsherrygeo@m.ai6yr.org Hoping you don’t have shared neutrals (like I had in a past home). I never figured out exactly what connected from Point A to Point C via Point F in that home. Electrical was wires in conduit but buried in drywall. Was thinking I needed to dig out the time-domain reflectometer and start chasing pulses, but called it good enough and moved on. Didn’t solve that mystery! Enjoy the bright LED lighting! A nice upgrade…

@tsherrygeo@m.ai6yr.org I know that the beaded-metal pull cord is stronger, but with no ground at the fixture, have you considered an insulated cord pull just in case that LED fixture ever shorts out to the mount? (Looks like there is a pull-lead coupler a few inches down from the fixture that could accommodate an insulated pull?)

@BoscoLab@social.tchncs.de Wish we had today’s wiz-bang cameras back in the day when I had a separate transmitter and receiver ham station. Backlighted dials, meters, and the tube glow from the top of the chassis was a treat in a semi-darkened ham shack. Don’t run across photos of these older stations often these days. Thanks for sharing your test equipment setup photos. Hope your LoRa signal comes along soon!

@BoscoLab@social.tchncs.de Full size test equipment has a significant ambiance when the lights are lowered a-bit (much better than my current USB-based gear). If you’ve seen one USB-Instrument’s PC display, you’ve seen them all. Not so for Hp856x and the other items pictured. Nice! #TestEquipment

@sundogplanets@mastodon.social Internet search: “Mazda MX-5 Miata: A specific mention indicates that the Mk2 and Mk4 Mazda MX-5 models often weigh in around 1250 kg (sometimes lighter, around 1100–1200kg for certain models).” Not a large car, but people might be able to imagine what size it is coming in like a meteor?

Nice day here in EN52 Chicagoland and catching up on some backup / field-day inverter generator maintenance for the off-brand inverter. Have fire extinguisher nearby. Will fill with fresh gas afterwards. (Unit placed to block sound at nearby neighbor. Shh! #HamRadio #FieldDay #EmergencyPrep

@g7vkq @relistan Might be able to use gear mesh pressure in the 3D printed design to eliminate the small meshing tension spring in the original metal version? Hoping there might be a home lab 3D printer in my future (once moved and having lots more space for one). More fun ahead! #HamRadio #RadioTuning

@BoscoLab@social.tchncs.de Very nice setup. Curious to see how the stabilized setup works out. My Fluke sweeper is only happy when sweeping and has fair to poor stability when in CW mode… (Lucky to have other sources that are far better for fixed frequency use.) #hp #Agilent #Fluke #TestEquipment

Ever have one of those days where by the time you get through multiple restarts & rounds of Windoze updates, that you forget what you had pulled out that laptop PC to do? At least now the silly thing can’t find anymore updates and will be ready for the next time (provided I don’t wait too long to power it up again). #WindowsUpdates #TimeWaster

@Pepijn Nice listing of critical factors for smoke alarms. Installed four replacement Wired/Battery interconnected detectors this past weekend for a family member. Took about an hour to install/test all (including finding and labeling power shutoff breaker) and cleanup. Well worth it as they were > 15 years old! Thanks for being an influencer. #SmokeDetector #SmokeAlarm #tech #influencer
