Those 2 HP calculators have arrived, well-packed, delivered by Evri.

It seems that the 17BII, on the right can be switched in and out of the RPN mode when required manually, need to read the manual later for more info, but now its boy dropping off at work time and a spot of shopping, in this stupid heat, I must be mad.

will confess that if those were in the calculator tray at the thrift store i'da bought them.

on an unrelated topic.......finding solder blobs and jumpers on cartridge fuses........WTF??? 
I did, £14 delivered for both, bargain  :-+

just returned with a 1.5 kWp PV set which is stackable to 3, 4.5, 6, 9 ...
Had a long discussion w/ the authorities regarding building permit etc

Will need to take some measurements, however the administrative guy responsible told me that he liked my approach and would support my plans.

The simple answer is that it’s impossible to make things idiot PROOF.  The best you can hope for is idiot resistant, and achieving even that is a pretty tall order.

On the Bench Today: NEW A1 SIZE CUTTING MAT   

      https://www.amazon.com/dp/B08FM3ZP4V

One of the things that evidently didn't survive either move were any of my cutting mats; I've already got some marks on the marble countertop, so time for a new one. I've used the grey FISKARS ones for quite a while now, as they're only $30-38 in A1 size; but they're only a 3-layer mat, and the last one I got at Wally Wurlld just reeked of plastic outgassing for over a month.  :o

Today I found this one; a 5-layer mat with a nice metric side, and with the current 20% discount it's only $26.

When it gets here in a few days I'll post real pics and first impressions. If you're needing a new mat, this could be a killer deal. No idea if those outside the US can find this one with similar discount.  :-//

FOLLOWUP:

*knock at door... pitter-patter of footfalls... vrooom...! of truck pulling away as I open the door to find a huge flat Amazon box*


* SQWEEEEE!!! of delight  as mnem scurries away to the dwagon-cave with his prize*




First... I need to clear off the bench...




*plop!* Oh yeah, baybee!!!




Construction is a really nice, dense 5-layer with solid layers and foam with just the right rigidity and a nice grippy surface, over 3mm thick. Heavy too; balanced on edge on my kitchen scale, it weighs 1.7Kg.  :o Even working right on it like this, outgassing plastic smell is barely noticeable. Much better than my last two mats.  :-+

And as always, the only time I can actually lay paws on my good tape measure is when I don't need a tape measure...  :o




Print is nice and crisp, unlike many of the "green mats".  :-+




THE MONEY SHOT: View from the "captain's chair". This pleases me...




...now let's get it dirty!!!  :-DD

So far, I quite like the initial quality of this mat. At $26, a steal of a deal... but evidently it is sold out right now.  :-// I'd say it still warrants watching to see if it comes back in stock; even for a few dollars more than the Fiskars, I would take this one first. I like the protractor print better than the Fiskars nested rectangles, and it doesn't stink me out of the house.

I had cause to rouse the Swiss Bastard today and put him to work.



I will never get tired of that gag.

Say what you like about the Swiss, and I know some would be prepared to wax lyrical on their many perfidies, but they do know how to make a damn good file. This is one of those tools that it's always a genuine pleasure to use.

Maybe, maybe not. Everybody had zero feedback at some point. If you're nervous, get in touch with them. If they're genuine they ought to understand and not take offence. Just follow the "treat others as one would like to be treated" rule and one can't go wrong (unless one is a cheating unprincipled scumbag with all the morals of a rabid hyena, of course).

If it's lots of your listings, I'd guess globfly bidding bots. Your stuff is probably no minimum and some interesting term in one or more of your listings; the controller will often then direct their bots to camp out on all your listings.

One of many reasons why I usually put a starting price that honestly reflects the minimum I'm willing to take; it weeds out the dickbags and bots and cheapskate Ferengis ( no offense, bd139 ;) ) hoping to get something for nothing, leaving only serious bidders.

You can refuse to sell to buyers with zero or low feedback, you're perfectly within your rights on the eBay terms of use; particularly if something feels off like international buyer and request to pay with escrow, or asking for a serial#/IMEI before paying, etc.

Cheers,

mnem

I normally include a in the description to the effect that I will not sell to someone with poor or inadequate feedback. No problems so far.

I'd also look at how long they have been on fleabay, and whether or not they have purchased vaguely similar items before, e.g. someone that has bought solder/resistors vs toiletries/clothes.

I wouldn't worry about offending such cheapskate Ferengis; they just smile in another Ferengi's prescence.

When at hamfests and someone asks my prices, I tell them cheaper than fleabay but not so cheap they could simply flip it for a large profit.

On fleabay, I simply state the price and that I will take non-stupid offers; that weeds out those that offer 10% :) I will sometimes do an informal dutch auction, occasionally reducing the price.

The only time I will consider an auction is when I can guarantee there will be multiple bidders, since in a normal auction the price is set by the second highest bidder.

So a bit more detail on my cheap portable colour spectrum analyser. It's primariy a cable TV / internet network test tool. Make is Sunrise Telecom who were bought out by VeEX. Model is a CM2800E. It's a WinCE based portable with a 6.4" touchscreen. The spectrum analyser covers 5 MHz and 1100 MHz. Minimum resolution bandwidth is 30 kHz. It has peak or average detection, peak hold and comprehensive markers. It does not have demodulation but the unit also has a selective level meter that has analog and digital demodulation. This makes an OK receiver. Also included is a RF generator / sweep generator. It's network connectable, has USB and CF sockets and will export data or screen shots Overall it makes a very nice unit for level measurement and interference hunting.
As I have enough SA's I'm going to ferengi this one and have just bought a second one for just a little bit more money  :D

Does this mean 75 \$\Omega\$ input impedance?

Yes, but not an issue for intereference hunting and can be fixed with a transformer or minimum loss pad. Has interchangable connectors for BNCs are an easy option.

I have just discovered that I'm not the only person here who loves calculators, it turns out that our benefactor Dave has quite a good collection of his own and he discovered that his Casio FX135 had the batteries left in, Varta anti leak and guess what, yep, they leaked.

EDIT:
Surely then, that must mean that all talk about calculators must be deemed as on topic  ;)

Daughters paper work is also sorted, exchanged today, completion on Monday.

I thought I was finally rid of her and that she was an independent adult. Doubly so since the car I lent her has just been totalled when legally parked. Clearly no fault, but still a major pain in the backside in the middle of "ice cream high season"

Oh no. I've been informed that there are Things she will want me to do on her house.

I'm pondering whether I will make it to the FRARS hamfest on Sunday, and/or the Rugby hamfest next weekend. Both are equally distant.

Any recommendations based on past experience?
