Those right angle standoffs are actually hinges. you did not need to remove them; just unscrew the other side of the board and it hinges up. That preamp looks like a great box to make your own custom LAB stuff; already has BNC's. Looks like there was something hiding in the big aluminum block at the other end. Yeah, when I started, the draftsmen were doing 2x and 4x PCB masks with tape and precut pads. We were doing 0.012" traces high tech ;)

Dave is going to get like 15 telephones in the next mailbag because he mentioned he needed one.

I'd say that antenna looking right angle bracket on the scanning electron board is a hinge to let you raise the board up and out of the way to get underneath

Just finished my thesis in electrical engineering, what way could possibly be better to celebrate than with Ben Hecks “Speak and Dave”?

18:40 those right angle stand offs look to also double as hinges. =)

I need the Dave speak and say so that I can constantly be reminded of the EEVBlog when I am without internet!

Dave, Gemstar was the company licenced under JVC to produce G-Codes for VCRs to record a show out of the TV Guide. That gadget would sit on top of the VCR and hang over the front and at the correct time, it would change the channel on the VCR and hit record, by blasting ALL the codes out for ALL known remotes. That thing kept the time and the date though, and could supposedly be put anywhere in the room so long as the IR signal could hit the front of the VCR somehow.

The Showview thing is an automatic universal remote for a VCR. It has a built in clock and if you programmed it, by entering the showview number, it turned on your VCR, set it to the right channel and started, and later stopped, the recording. Before that, you had to program it to let it know which channel was stored on which number on the VCR. The numbers are still printed in some tv guides and some modern DVD-recorders still offer showview programming. In some countries, the system was named VCRPlus or Videoplus. There was also a "deluxe" version you could use as a normal remote for your TV and VCR. I had the deluxe version and I think my parents still have got the version you got, but rarely, if ever, used it. It was easier and more logical to enter "monday, 20:15 to 21:45, memory 5" into the VCR than a 10 digit number.

Showview was basically a remote control just to setup your VCR to record a show from TV. Many people were not able to program their VCR by using the built in menus etc, too complicated. So they printed codes in the magazines like "291 582 294 911 812" for every single show. You only needed to enter this code into your ShowView device and point it to the VCR like the IR remote control. Bang, the show got programmed for recording.

When you said you had never had a Reese's cup my jaw dropped...

Wow, I watched Ben Heck build the SpeaknSay, was surprised to see it turn up in the mail bag :P

It's fun to see the live stream repeat to see how you do it and then the actual video to see the close ups and details of the things that you unpack! :) loving it

How many people do you know that get gifts all year long? :-) Must be nice.

show view was a system where TV guides gave out codes so you can simply punch in a code and your VCR perfectly records the show where it exactly cuts recording when there is a commercial breake and then restarts recording once the show is back on. was a nifty idea

I have a little brother, he can read and write, so it is time he learned about electronics. This seems like the perfect add-on to his instruction

I remember G-Code in guides, Panasonic used a barcode version. they also had a barcode sheet with Record start, end times, days channels etc... Manual programing was easier, Day(s), Channel, start time, end time, remember insert tape, wound to begining, press timer record and set operate to off. I learnt to program an old JVC vcr back in the late 80's when i was 7ish, the instructions were on the front door. amazed me for years how many didn't know how to set the clock.

In shool (for Electronics trainees) we are still using those Unigors :) On the measurements we do there we don't need that high accuraty so Analog Multimeters work fine. The main reason they are still used is a): They are still working fine and b) They are basically like indestructable. You can't blow a fuse. And trust me, my classmates aren't that carefull using stuff so you'd have to replace fuses every day.

Dear Dave, My name is max pincu and I live in Dallas Texas in the USA . I have watched your AMAZING blog since I was eleven. I especially love teardown Tuesday and aspire to be like you one day you crazy Aussie! I hope to meet you one day and see the lab if I ever visit New South Wales .

I will give it to my child, and he will play with it and learn the wonders of electrical engineering through your inspirational voice.

We used to have Showview codes printed in the TV mag in the Netherlands. I never used it though. As I understood it, you have to enter a string of seemingly random numbers to program your VCR. It'd be easier to just program the VCR with the times. Our VCR remote had a different system, which used a red LED with which you could swipe barcodes, and that would automatically set the VCR start and stop times in the remote, all you had to do then was click the 'Send' button to program the recorder.

i had such a vcr recording showview device back in the days, it works with every vcr that has a remote, you programm the recording time into it, and it sends out IR pulses allthe way around it and forces the vcr to record at the desired time. you can use codes provided in the manual to st it up for different brand vcrs. its just like a multi-device Ir-remote but programable to do differnet things a pre set times, really handy thing

When I was going at school in 1986 we use unigor multimeter, you could always hear when somebody tryed to measure voltage in AMP there came loud click when the thermo fuse popped. :-)

Those ShowView codes were pretty common here in Finland during the VHS era. I remember all TV schedules in the newspapers having the ShowView codes after each television program. Made it easier to record a program just by punching in code than manually set the date, channel, start and end times.

I remember that showview on a VHS-VCR. In TV program guide they had these showview number for all the movies and show on TV. You only had to enter the number to program the recording.

I have been waiting for this my entire life. When I left the womb my immediate thought was Dave Jones sound spiny thing.

Did I just watch a grown man eat his first Reeses Cup?

On that scanning electron microscope module, those little PCB mounts you said look a lot like a part from antennas, well, they used those as a hinge so you can remove only 2 screws and pivot the entire PCB like a door!

29:30 for the thumbnail image.

My family used a thing like ShowView called VCRplus way back when. You'd get recording codes from TV Guide for each show listing, plug them into the device, and when the show came on it would IR blast your VCR with the channel number, record and then stop.

I would really like to have the speak and say. My engineering teacher at school also watches your videos and it would be so cool if i surprised him with it at school. It would also give us an excuse to watch you vids in class :)

The "prototyping" area is probably for a custom logic interface to whatever computer you're connecting to it, there weren't really any "standards" for this type of thing back then.

I love that cradled dip switches in ev-meter.

Your swiss army knife is in dire need of a good sharpening! Love the mailbag. Thanks for all the great videos!

I would leave the speak'n spell to modify the code so that Dave speaks when the wheel stops!

The ShowView is for programming VCR's without actually using the VCR. TV programmes used to have a ShowView code next to interesting shows or movies which you had to input into the ShowView device. IIRC the ShowView either sends the decoded time/date/etc to the VCR and programs it, or it just sends "record on channel XX NOW" when the show starts.

Hi Dave, That Showview device was made for a thing you could use for your VCR. There was a showview code in the programguide and that code you punched into this device. Than the device sended the recording program to your VCR so that you don't have to program everything. It was used in Holland too.

You have so much equipment is there bow you're going to need a huge grid of sloar roadways to power it all... If they weren't total bullshit! LOL :)

I do have schematics for the 2003 preamp if you still want them. Kevex is still around, they became part of Noran and then a part of Thermo Electron.

4:00 the ShowView was a device used to program VCRs for shift recording, on program guides there were codes which you had to put on the device and the device transmitted at the VCR the time of start and end of the show, many later VCRs came with ShowView operation on their remote so this was probably a device meant to enable old VCRs to be programmed

Maybe that error in the multimeter is because you have to use it in an horizontal position. That is written in the low-left corner of the scale.

Having the speak and say would be awesome! Because It is like a quote generator and more importantly it is a combo thing between my two favorite electronics related youtubers!

Thanks Dave. I can't wait to see the teardown of that analog meter!

I want the Dave speak and say because it would just be awesome to have! I wouldn't stop playing with it and listening to some of the things Dave says! It would really be awesome to have.

Hey Dave, you might noticed the meter orientation symbol on the multimeter gauge panel. It says you must place it horizontally in order to get full precision.

ShowView was/is a way to record programs. This device is probably for hooking a non-showview device up to use the service. These codes where/are published in TVmagazines, and you could program these in, and then it would start recording at program start, when they broadcasted the showview code, and end at program end.

18:35 The right angle mounts are hinges, you can hinge the board up!

21:40 - I think it's a double transistor package for matched, thermally coupled devices, perhaps used in a differential amplifier (input of an opamp) cicuit.

I admit that some of the stuff you talk about goes over my head. That being said, I learn something with every one of your videos I watch. I love the enthusiasm, it's almost contagious. Thanks for the great show!

Those "right angle spacers" for that pulse processor appear to act as hinges for ease of service...

Another taker for the Speak'N'DaveJones here! I'd quite like this thing as at college (electronics course, total BS sadly). Most of us there quote you in the lessons which leaves the lecturer somewhat bewildered (although he always is - I've corrected him so many times now that he sends me out whenever I do). An extra added touch of real Dave Jonsiness would be a really good addition to my course.

how that showview thing works is it acts a bit like a universal remote. ie, you would either program a code into it from a code list or program it yourself manually and it would, at the correct time and date, send an ir remote command to a vcr to start recording the program. you would leave a blank tape in the vcr ready to record and this little unit would command the vcr to start and stop at the right time :)

Very vintage mid-70's TI calculators like the TI-2500 are awesome, I have several of them, all in DAMN WORKING CONDITION after a simple cleaning and replacement of the Ni-Cd battery packs...

The show view must have been one of those RF remotes that could turn on a VCR and set it to record and stop before the age of programmable VCRs.. Old tech!

Those angled standoffs are hinges. If you took the 2 screws out on the other end of the board you could rotate the board on it's hinges to see what's under it. And it allows you to easily test it with power on it and board swung out of harm's way. I've seen this in some military stuff.

The whole wire wrap thing on the 74 chips makes me think nothing but an acient PLD

Hey, Dave, check out the 1 kV rating on that cap in the pre-amp module! Awesome! :)

We have a Multimeter almost exactly like that at work, I might take a look tomorrow. I never noticed it's a Metrawatt though

lol I remember those showview things...they used to print a 5-digit code in the tv guide that you typed into your VCR and it was supposed to automatically record the show..it never worked though lol. I guess that's a standalone one?

I want it! When I'm stuck during my design hours, this will give me good advices! =D

My sister walks past my room when I start watching Ben's show and I recite the opening phrase off by heart. I also do the same for yours. So when I heard Ben was making a project inspired by you I was just a little excited. So I would greatly appreciate the speak and say

I did't expect to see a dil circuit in a Texas calculator from this time.

I can't believe how simply calculators can be constructed!

34:10 - Q: "Do you like Franklin?" A: "I don't know - I've never frankled!"

those right angle standoffs at 19:00 in are hinges so you can raise the board up to access underneath it. You've seen things like this in 80s AV equipment, but made out of flexible plastic.

The puzzle solver chips are most likely a micro-controller (to drive the display and run the software) and a (P)ROM/NAND chip to store the dictionary.

Max was the ausie Interceptor, Dave is the ausie Receptor. Awesome stuff!

You and Mr. Ben are my role models. I'd love to have something which resembles both of you. Thanks Dave.

40:46 - i don't think the chip is soldered in. the melting point for that plastic is very low, so just a soldering iron nearby and you will destroy it. the holes for the DIP-IC is probably trough-hole plated (black carbon), so the chip makes contact just by sitting there. Nothing is soldered, that would be too expensive!

hey, on the last item (the letter about the hydra e-vehicle charger) the guy mentions he wanted to give away one of his units, and wanted you to choose a winner, Dave! I think you were in too much of a rush to get home and didn't notice it at the end of the letter :)

I think that showview is a videoplus - back in the day before VCRs could be programmed to self record on a timer you could program a little box that worked kind of like a universal remote to make your VCR record a program. Here at least, TV guides used to come with number codes to make the programming easy.. i think that's what that is

I find it quite interesting that school, for me, was the only time I used an analogue meter good to be taught but they're not really useful anymore

can't believe dave has not had peanut butter cups! practically a staple in the U.S.

There is not a cat on that thing! A toy without cats? Brilliant! Cats are evil, i think you know it. I´m a big fan of your vlog and i follow the stuff from BenHeck since he wasn´t even on KZfaq. My wife is pragnant, this thing will teach my son with the most popular phrases of electrical engineering! Without Cats! Dave! Gimme that thing! :) Greetings from Hamburg/ Germany. :P

Ben Heck FTW! I've been following him for over 10 years! I even made an Atari 2600 portable based off of his designs. Back when I had my own vintage video game shop, he ordered 20 Atari 2600 boards from me to make portables from them. Brilliant!

We usw those analog Multimeter here in school :) cool.

I'm an electrical engineering student. And the lack of Australian EE lingo is holding me back! Therefore, this device will help me see through my dreams of becoming a bi-lingual EE. (Australian and English) ;)

having had reeses peanut butter cups after they melted the flavor does change a bit. next time you hit the states unless they sell them in australia, you should give them a shot fresh. can be found at just about any big box store and small local store.

I'll have the eev sound board game. A guy I work with hears me watching the eevblog and your voice drives him crazy. That's why I want it hahaha! Great channel Dave.

Bloody hell! I used to have that exact same calculator! It was about twenty years ago, I was in and out of hospital about once every four weeks for IV Immunoglobulin. I was in for one of my teen birthdays and got that calculator plus a 35mm film camera :D Bobby dazzler! Thanks for the memories :D

2020 to 2014..... Ah, the classics! 👍😎

These mailbag videos are hilarious. People send him stuff and he totally shits all over it. Incredibly enjoyable.

You think that calculator was cheap, I bought one at the Dollar Tree for $1 that was actually made of paper on the inside.

I need the the SpeakN'DaveJones as a decision decider for my life choices

I want the Speak and Dave Jones primarily for the creepy looking cow in the corner. It just looks like it knows that it's been modified and is extremely unhappy.

I have a Casio HS-8G solar-only calculator which has a bare die mounted directly onto the flex and a cap just sitting between the two layers. It's also invincible.

The description is on the right for me.

I'm amazed there aren't peanut butter cups in Austrailia!

4:48 holy fuck, they've used a whole arrangement of through-hole as surface-mounted stuff, and the SMD stuff that was meant to be surface mounted was hand-soldered it seems

0:14 That moment when you forget what number comes after one.

I recommend you take a look at Open Broadcaster Software too. It may not be as easy to use as xsplit but is at least as powerful once you know all the misc and plugins.

I loved watching the build video on Ben's channel! Which btw lead me here! Love the See and say!

I want it to TEAR IT APART!

i would love that speak and say for my baby bro! best way for hum to learn his technical terms!

"She who must be obeyed" - That's just AWESOME :p

I want it because I want to smell the smell of Australia left on the thing. It must be strong!

I want that toy to wake me up in the morning "Don't turn it on, take it apart!" :)

29:36 oh Dave… that would be the "See-n-Say: Dave Jones Says"

Hold on, you didn't know you can buy Oreos here? They're everywhere!

I only understand 15-20% of what you say. I would love to have even half as much knowledge as you. I'm still considerably young, but you are a true inspiration. Thank you for all these videos, I try to learn as much as I can, and while it's usually only a little, if I had a better understanding, then I would understand so much more. Any recommendations on how I may pursue a field like this, and start to learn?

I would like the Speak and Say Dave so that any time I am working on a school project and I need one of the half broken oscilloscopes to work, I can have you say "Its your average 30 year old technology".
