Shahriar's basement lab is absolutely mind blowing to me. I love both you two guys and it's great to see you both talking shop together like this! Thanks for doing this Dave and Shahriar. Great stuff. Fred
Shahriar is awesome. He's broken down some particularly complex concepts (particularly in RF) that even a noob like myself can follow along. 👍
In any way Shahriar broke the myth that workspace of a good engineer needs to be messy! Amazing to see how highly productive this young man is. His content is about more advanced stuff, which is, beside the specific knowledge, hard to begin with due to the costs. The most equipment involved is quite expensive. Just proper cables are very expensive. But very valuable to learn from him. Thanks Shariah. For now I am playing around with a few hundreds of MHz up to WiFi and Bluetooth 😀 which is "DC" for mm-wave engineers.
15:40 I collect video equipment. Same here, you sometimes just can't fix something. Custom chips, mechanical components, lack of documentation, and dare I say it sometimes a lack of experience of a particular system, does mean that some projects just have to be abandoned.
23:20 Install some moisture sensor alarms for peace of mind. Years ago I fitted these around various plumbing above my studio and once one went off, sure enough a pipe fitting was dripping. Caught it before it could do any damage.
Lovely to see you two! And nice cat. TSP has a magnificent lab with sooooooooooo much gear that even Dave and CuriousMarc combined are no match :)
Building shifting is real shit, oh yes...
Yeah, but Marc got another level of vintage equipment stashes Shahriar doesnt have and/or need :) Both are brilliant guys in their own game!
To monitor flooding, just have a damp detector/alarm rigged on the floor. Places that do flood all the time, like my old pub, had a small hole on the floor with a sump pump that had floats that pumped the water out of the hole and out of the building when the water reached a certain level.
Electroboom's lost brother.
Basements.......Same in the UK sadly, what I wouldn't give to have a basement that the same size as our house floorplan!
That is an insane amount of gear in Shahriar's lab! BTW, Dave, you could always build a virtual house and lab with tunnels, fireman's poles, moats, and turrets if you can't do it for real. :)
I've seen university labs that can't hold a candle to shahriars basement lol
Я думал, что это комната с приборами при институте, а оказывается это нижний этаж частного дома и судя по всему частная коллекция.
Так как я живу в отсталой стране, при уровне тех заказов что мне попадаются, и уровень оплаты работ, никогда не позволит приобрести все интересующие меня приборы.
Все оборудование, которое вы видите, было сломано. Он покупает их на eBay по низкой цене и ремонтирует. Так он снимает свои видео на CZcams.
Наверняка он иногда перепродает отремонтированное оборудование, чтобы заработать достаточно денег на покупку нового сломанного оборудования.
Кроме того, он занимает хорошо оплачиваемую должность в Bell Labs, крупной компании, занимающейся исследованиями в области электроники, так что в свободное время он занимается этим.
My first job out of EE school I was assigned to the USS Carrier Kitty Hawk... worked below deck with anti sub stuff..
I am uniquely unqualified for that position 😧
Your cat is lovely! And I didn't have an electronics project kit as a kid, I had a chemistry kit.
Media: No need to worry about standby power consumption nowadays it's nothing significant
TSP Lab:
If this awesome video tells me nothing else: Shahriar needs to do more giveaways!! :D Joking aside, this is a fantastic behind the scenes collab w/Dave and Shahriar!
These pics put every lab I've worked in to shame. We also have software guys using ours so they break stuff a lot!
I can remember keeping several computers on all the time, until i realized my electric bill was out of control
Attovolts !
Fireman poles are only fun until someone breaks a hip :p
RF is more of an art than anything else. You could build the same circuit 2 different ways. One will work and one will not.
This video is not starting for me :(
(tried on two consecutive days)
OH NO --- you guys again ! ;)
From 19:48 onwards, you exaggerate a 'bit'. atto is 10^-18, so maybe you can measure and generate 1nV (10^-9) at most, and about 1pA (10^-12A), or a bit lower, into the fA region.
Another myth at 20:39 is, that analogue metrology (V, A, Ohm) instruments like a calibrator or Shahriars 3458A need to be powered on 24/365. That is useful only for voltage references like the 732B, FLUKE 7000, or all the DIY LTZ1000 based ones, which mostly feature battery back-up for that reason. If you have 10 of them in your lab, these might consume 20W in total. An esi SR104 also does not need any power. What really is needed, is a very stable room temperature, like in such wonderful, cool basements as yours, or mine 😎.
The other, power hungry instruments are no real standards, btw. If you switch them on only before using them, they might need 4..8h to fully stabilize, then you could do an AutoCal, and have full uncertainty or stability following their specifications.
Therefore, Shahriar, there is no energy - excuse not to start volt-nuttery.
Microwave.... t'is the devil's work!
The blackest of the black arts in analog electronics, haha!
