Test Equipment Anonymous

Nothing wrong with making a big profit, I do that when I can But I at least wait until I've received the item and tested it before advertising it and I don't use other peoples photos (whiich may be illegal)

Quick game of "spot the difference" www.ebay.co.uk/itm/Olympus-CELL-Digital-laser-system-LAS-561-50-/354495754439? and www.ebay.co.uk/itm/255918041132? The seller has done the same thing with items from RAMCO using their pictures and listing the item before they could possibly have receive...

Just a scratch that. Apart from the left index finger tip that dropped off, I've also managed to amputate the end of my right little finger, through the bone, and crush the 3rd finger bursting it like a ripe banana. And to make iti nteresting it was in the middle of the Jordanian desert 200 miles fr...

I did a "change your own dressing" once and the end of my finger came of with it That was caused by the inapproriate use of a local anaesthetic with adrenaline on an extremity.

The "Nano VNA" things are interesting but are pretty limited particuarly the cheaper ones. When they say to use a 10dB attenuator on each port to isolate the mismatch (the ports are not 50R) it makes me worry. Their dynamic range is low enough without knocking 20dB off before you start. If...

I've been thinking about getting a NewScope LCD replacementfor the CRT display in my HP 8753B VNA. The NewScope upgrades it to colour, less power weight and heat. Unfortunatly the required model (9) is not currently available due to supply shortages. Looks like it uses a Xilnix Spartan 6 FPGA. Farne...

They say the NHS is safe in their hands, well I have my doubts, the public message about the 111 service is certainly a lie, that they can get you sorted in as little 90 seconds, look at this video taken today, the 931221 on the screen is the answers to 6 short recorded questions posed to you, I wa...

Hey Rob, this is for you.... 2022-12-25 23_53_47-Window.jpg My first Pico! 6403D. Quick one... why they put the "tuned probe TA150" in the label, can't I just use the 10:1 probe I want? Sure I will compensate them.... Ohh, very nice. Better bandwidth than any of my picoscopes. The "t...

I never ONCE said they were a good idea... only that they are everywhere, and that NiCd is NOT dead; it's just lying low in craptastic products like these. If you guys in the UK really have gotten rid of them, it's only relatively recently, and "GOOD FOR YOU!". And I'll bet more than a fe...

Except they are not being discouraged. As I said, they have enjoyed quite a resurgence of late in just this niche market. Whether we like the idea or not, they are all over the place out in the wild, and are not going away any time soon. :man_shrugging: And I'd bet you a buck-converter that "s...

Latest aquisition arrived today. a Multimetter [sic} Televes-multimetter.jpg It's actually a TV test box including analog and digital receiver covering up to 2GHz and a spectrum analyser . Cost was £9.99. It has a tiny colour screen that can also display external composie video. I need to find a SCA...

More expensive lights like you're talking aboot, I'm sure they can afford a proper Δ-peak charge circuit for NiMH. But everybody, even Wally World, sells a dozen different versions of these Chinesium walkway lights, etc that all use the very basic charge & Dawn/Dusk circuit found in these POS o...

Today's Project over my Morning Cuppa... https://teanonymous.com/f1/download/file.php?mode=view&id=461 These silly little gewgaws leverage commodity LED/solar sidewalk light tech to make a novelty oversized Xmas bulb ornament. I picked them up at Dollar :christmas_tree: Tree along with the sill...

More TEA :o A package tirned up today. Its my £50 Picoscope "2204A" and as expected, rather than a 10MHz 2204, its a 100MHz 2207A :D Even better it has the blue Pico USB lead and two TA132 150MHz x1/x10 switchable probes. None of these were in the listing. In fact it said it was a 2204A-D2...

One presumes a "dial indicator". Which is, if you think about it, a pretty poor name/description as that phrase could refer to any of a thousand things that use a dial to indicate something, for instance a watch, but that is nevertheless the customary and generally understood name for one...

Been quiet here. So I put an offer on some TE on ebay. It was more than the auction start price but was declined. Nice note from seller saying he had a number of watchers. So I won it with a maiden bid
Do you know what it is.....

Yesterday I made an offer on ebay for a Picoscope (BIN with Best Offer). 'scope was listed as a 2204A (10 MHz BW 100 Ms/s) but the image was of a 2207A (100MHz 1Gs/s). Got a message today saying they had just noticed the different number and was I OK to have the 2207A instead? I replied saying that ...

I do now.....

Don't beleive all you read on the web. There are lots of "experts" on all subjects spouting rubbish. Thanks Rob, you read my mind. I will try to contact Adafruit to correct it. That said in the 3 wire configuration they are somehow right, the ADC remove the imaginary drop on the negative ...

This 4 wire meas explanation https://learn.adafruit.com/adafruit-max31865-rtd-pt100-amplifier/rtd-wiring-config#4-wire-rtds-2928771 is not what I was expecting ( I mean ) Datasheet MAX31865 https://cdn-learn.adafruit.com/assets/assets/000/037/309/original/MAX31865.pdf bah....

No problem with my DeWalt oscillating multi-tool and velcro sandpaper.

Won the Cropico milliohm meter I talked about earlier. Classic snipe operation. 0 bids up to 3 minutes left, then someone left a starting bid; at -30 seconds a second bid came through, and I shot the competition to pieces at -3 seconds.

A bit better luck with the Philips (actually designed and build by Labgear here in Cambridge) PM 5503 TV test generator. It works perfectly. Even the RF output is OK. Yes I still have a TV with an analogue tuner :shock: . Its one of those "no subsitute" bits of test gear and I've not had o...

Back to TEA My purchases from the last Peaker Pattenson auction finally arrived today. A TTI TS3021S 30V 2A power supply and a Philips 5503 TV pattern generator. Looked at the power supply first. No obvious issues visually. The bad news is the ouput is pinned at 42V :( So as the service manual is av...
