Test Equipment Anonymous (TEA) group therapy thread

I guess I should really look into this "dischord" thing, I assume there is an application you need to install like teamspeak or ventrillo?

maybe next week

The invitation link is on P1 of this thread.

No need to install anything. It'll run in the browser. Text and/or voice.

We had 10 people on TEA Time today. 1.5 hrs in and there are still 9 standing.

Yup... I made it thanks to a friendly reminder from tautech that stopped me on my way from the front door directly to Amazon.

Oh, yeah OK, maybe I'll try it next week. I tried the link and it is asking for login details, is this the same as we have for EEVblog or do we need to register an account on Discord first?

Yeah you need to join up and best to use your EEVblog login name so we know who's you are.....unless you're shy.

If none of your other haunts use Discord, yeah you'll need to create an account. Use your SPAM-catcher eMail to receive the confirmation eMail and you're in.

There is also Coffee and more important Cookies  https://discordapp.com/channels/658020677533827101/658020677533827104

Thanks for the lovely coffee.
But the cookies look suspiciously 3D printed just to prank us.

Fairly safe on that front I don't have a dual extrusion printer. But seems how this is Oz who is to say the choc dots are not flies in the mix

Of course, alltho it would fun to come among everyone without disclosing my full identity  but only a troll would do that....do we know anyone that fits that bill?

Apologies for missing the discord, here is a little eye candy for the TEAd.

Things must be bad you can't afford the Electrons to run the dotty displays for us? 

[WastelandTek]

that bottom 5381A needs moar retrobrite

[bitseeker]

It's a color gradient as you move down the stack.

That's quite a collection you've got going there, Rob.

[VK5RC]

The bottom miscoloured unit, I think it is not plastic discolouration but paper change behind a plastic cover.
Unfortunately at present they are in the garage where there is no power, in the next day or so, I will try to get them fired up. 👍

*off in search of a better HDMI switch*

If you find one let me know, mine regularly crashes   

Yeah, mine was purchased because it was well-rated and an "Amazon's Choice" for only $15 Canadian; but it seems to have a cyclic glitch every 30-60 seconds. I was going to just hit the local Best Buy for a name-brand replacement, but they were nucking futs; having only one no-name Chinese import model in stock at $113.

I've decided to do some testing to see if I can find the cause before I send this one back; I have until March to get a answer.

Wow, that's way worse than my problem. I just get no sound and/or picture sometimes when switching sources, or sometimes the sound drops out when  the screen blanks (ie on game loading screens).

EDIT: Wow that's some serious negative delta t, you should glue some Peltier modules to your ears and generate some electricity...
   

Found the culprit. Was a HDMI cable with a borked pin. Weird; it actually caused a glitch on both devices connected, even tho it was only on the Roku. Straightened the borked pin with a dental pick and all is well; been watching HD content & playing Street Fighter IV with my son for hours.

This is the HDMI switch I have: https://www.amazon.ca/gp/product/B07MSG1LXS/

It does both IR remote and auto switches to whatever input just became active. They only include a USB power cable, no power pack. My TV doesn’t provide enough current to run it through the HDMI, so I’m powering it with an old 1A white cube iPwn charger; they seem more reliable than most for continuous use. The remote takes a CR2032 even tho the instructions say CR2025. 

I’ll post followup in a few months; let y’all know if it all keeps working.

Nice! I always prefer to find something easy and mechanical to fix on such gizmos; board level repair on something like that is way past my gear and experience levels.
Pretty sure my problem is glitchy firmware, as turning it off and on again always fixes it...
They seem pretty identical in function and capability, I power mine off a Samsung phone charger, and I always try to cram a 2032 in place of a 2025 if I can, as I have a near infinite supply of cheap ones   
This is my wee beastie: https://www.ebay.co.uk/itm/4x1-4K-HDMI-V2-0-Switcher-Audio-Extractor-RCA-Converter-3-5MM-Jack-Optical-SPDIF/293040696886
Interesting how ebay will show purchases from the beginning of time on a mobile phone, but nothing older than a few months on my pc   


Sorry for any confusion on Discord yesterday regarding my nickname. I pay play (wow, interesting Freudian slip) an MMORPG called PWI (officially Perfect World International, but I prefer Picking Wallets Insultingly) and have used pretty much every chat client available in the various guilds I've been in.
I didn't even remember I'd already made a discord account... 
Since the guild I'm in now uses Teamspeak, I'll try to remember to change my Discord nickname from Spara (Sparafucile is my ign) to ThickPhilM for next time!

I like a Moscow Mule   

(vodka, lime juice, ginger ale)

[Kosmic]

Found a new usage for my reflowR (normally used to reflow pcb). Make a nice and stable hotplate 



I'm using it to heat up mineral oil to precisely 60 deg. Trying to measure the Seebeck effect between a copper wire and a brass tinned binding post, not working so good right now 

Improved setup. Got a clean hot and (almost) cold junctions now. Heat transfer from the plate to the base of the binding post is not great though. I need another thermistor 



In any case, it's working a lot better now. With the hotplate at 70Deg, around 20uV are generated. That's around 1.7uV/DegC. which is ballpark the value I was expecting.

Did you mean ginger beer instead of ginger ale?  Very different and should be ginger beer.
