sigh I really need to come up with a reliable and inexpensive way to power cycle some equipment remotely.

My is up and running but the two software defined radios aren't responding even after rebooting the computer. The computer was involuntarily power cycled twice yesterday when the power went out and when the backup generator transferred the house back to the grid after grid power was restored.

Or maybe the SDRs need to be reseated in their USB ports? 🤔

@douglasvb @ai6yr

Hmm, maybe you can rig up a USB cable routed thru a relay board, and a script that uses that to reset the +5V supply line when an issue is detected?

@douglasvb @ai6yr

Probably... I was thinking of a little USB-C power switch dongle that came with the RaspberryPi in my shack. It seems to just be a latching switch that goes between the power supply and the RPi to let me switch it off without unplugging it. But that isn't necessarily the same as a device that has data lines connected.

The box with the pi was marked Canakit, this appears to be the product. You might find the same thing elsewhere.

Either I've ordered too many things from DXEngineering, or they've just given me too many stickers. Now- what to do with all of these?

kc2ihx,
@kc2ihx@mastodon.hams.social avatar

@bud_t

Even if you check the box saying you don't want stickers, they still send them!

kc2ihx,
@kc2ihx@mastodon.hams.social avatar

@bud_t

Yeah, but like after three orders from them you have enough to cross from "hey fellow hams, I too appreciate a well organized online ham store" into walking advertisement territory. My water bottle got a small one, the car roof box and my tool chest got a bigger ones, but I don't plan to use more than that.

(And the water bottle and roof box also have N7KOM stickers)

Interesting, saw someone selling rooted grape cuttings at the farmer's market at $30 each. (I have so many in pots in my backyard which I cannot give away, LOL).

@bud_t @ai6yr

My grad school roommate would complain about how all farmers markets were ripoffs, and I was always saying he should try going to one other than Boulder's. Not that there aren't other expensive ones, but the prices there were absurd.

(As a farmer market regular where I live now, absolutely. But something about Boulder CO drives the farmers market premium through the roof)

Reading the wikipedia article on microwave ovens and found this sentence in the part describing the frequencies they use:

"The third, centered on 433.92 MHz, is a narrow band that would require expensive equipment to generate sufficient power without creating interference outside the band, and is only available in some countries"

You know what this means? With a big enough amplifier, you could cook your food with a Baofeng.

@kilroy_was_here to be fair, I want to see if I can do EME CW by pointing my old Sharp microwave oven at the moon, after disabling the door lock of course.

Seeking eggplant recipe ideas, as I have one limp eggplant in the fridge and 8 eggplants growing in hydroponics (which may produce a massive amount of eggplant).

So far my repertoire includes 2 dishes:

  1. Eggplant Parmesan (Italian)
  2. Eggplant in Garlic Sauce (Chinese)

(the family hates eggplant, except me, so we never eat it 🤔 )

I didn't order a mystery box (and kinda hate the idea) but I'm going to be so disappointed if it's a NOS TS2000.

Besides, I already have a 706MkIIG, I don't think there are any D-STAR systems I can hit from my shack, and that angled head unit just looks difficult to mount in my vehicle.

But I'd really love to see a new radios in the "DC to daylight" mobile sector.

"$200+ for an arborist throw line launcher!?!? I can make my own for $20".

It.... kind of works? (Video in thread).

The surgical tubing I bought isn't quite robust enough and it turns out pouches to hold the throw bag are a whole school of engineering unto themselves. I ended up spending $35 on a replacement pouch + tubing from an actual arborist throw line launcher. So am in $55 but that's still a lot cheaper than buying one.

Is that your shed up the hill? You said it was way up the hill but I hadn't realized quite how steep.

Finally got a chance to prove to myself that the $60 Eliminator I bought actually does something. Tuned to a local broadcast station with a harmonic on 3.960 that comes in S9+20, turning on the device, it completely disappears down to the S4 noise level that I am picking up across the band.

Only concern is that other than the power button, it seems completely insensitive to other settings.

kc2ihx,

@ai6yr

Kind of hard to tell with these band conditions...

The gain knob on the primary antenna (not the noise antenna) seems to have an effect on my background noise levels.

If I were to go hunt down an old ThinkPad as the one ThinkPad for my collection, given the Wallstreet PowerBook is one of my ever-favourites, what year & model should I be hovering around?

I've never heard of them courting Apple for a Mac OS license fee but that doesn't seem that far fetched.

I think this is the thinkpad in question:

@ai6yr somewhere in the ad I thought I read that all the cables were removed and in boxes, but carefully labeled for reassembly.

That almost sounds worse...

Ran some errands by bicycle today... surprised how easy it actually is to get to the store here without running into ANY traffic, if you know the back route. A lot more people could bicycle to the store, if there were a culture change (living in car-driven SoCal).

@meganL @doskel @ai6yr

My dentist's office keeps offering to let me bring my bike inside, as they don't have a rack, and the receptionist thinks "it's a rough neighborhood". Bringing it inside seems like a big hassle, so I usually just lock it to a lamp post or tree.

But yes, I try to carry my bike helmet in places to subtly signal that I rode my bike there. And I'd love to see the city or someone offer grants to businesses to install usable racks.

But my wood scrap pile goes in a container, and if I can't fit a piece in it, I have a rule that something else has to come out. In theory that ensures my scrap pile will just get better and not bigger.

Inspired by late night mastodon.radio conversations, I put in a low-ball best offer on a TRS-80 Model 102, not expecting it to be accepted, but it was. So I guess TNC field packet is a go? What have I done? 😜 🤠

Looks minty. I will order a replacement RAM backup battery and a re-cap kit just in case (battery certainly needs to be replaced), that's like $20 in parts. And a DB-25 to DB-9 RS-232 cable.

I have been much more selective in what junk I keep after having to clean out my dad's garage. (which was also full of stuff that came from my grandpa's garage.)

After you find the fourth or fifth 2ft bit of telephone or segment of hose, you start to wonder if there was ever a plan for it.
