I need this thing (Update - found one on amazon. WHY IS IT SO EXPENSIVEEEEEE)
Very useful video! I now know they aren’t filled with magic smoke! 😂
Really cool I remember when I was trying to fix a Uniden Satellite receiver they had a 3 or 4 pin part that looked like a voltage regulator or transistor but it actually had 50 parts inside It was SS and it regulated the voltage. The old days there would have been a section of 50 parts that did the same thing and took up 4 by 8 inches. Looking at old two way radios from the 70,80, 90s, the parts are huge compared to the parts now that you need a microscope to see
These were a game changer in the 80's and 90's industry for controlling loads like heaters. Never realised you could take them to bits. Very reliable but they do need a BIG hestsink
Now can you change it so you can use a public and private key just like regular encryption? That would be cool to see done with pen & paper as well. So you just need to know the peer's public key and never share the private key,
I wish there was a way to delete cards on your account as I have a few on there that ain't finished and made mistakes on them.
They get zapped in time, but we can delete individual decks if you need, email or ask on irc with the deck ID number
@@TheRealRevKwhat is your email address I will contact you, I have some ID cards that trying to make but struggling too
@@TheRealRevKnot sure how to email you, but there is a card I would want to keep if there was a way to lock it.
Also trying to order what I made and can't find it
Everyday for the past 4 days it has said “arriving by 8pm”
That’s so cool!
What is the app
NFC e-tag
Thank for sharing. I was a crypto tech in the army in Vietnam but had to cross train on tty because we only had one teletype tech so I had to cover for him when he was off and vice versa. I worked on telegraph or teletype ckts for 18 years.
Thank you for making this video. My first programming was done with ARS33 running timeshare BASIC on a Nova computer IDK 45 years ago. My only regret is that I did not get one of these teletypes when they were being trashed ....
I learned to program using a KSR33 (the punch/reader -less variant of the ASR33) and dial-up to a nearby school district's time-share HP 2000F running, for our use, HP BASIC. Eventually we computer geeks convinced our high school to upgrade from the KSR33 to the ASR33 and now we could save (punch tape) and restore (read tape) our programs rather than have to retype them frequently. Fun Fact: the answerback drums were setup, IIRC, just like the tape with 3 bits (rings of breakable tabs) on one side of a sprocket wheel and five bits (more rings of breakable tabs) on the other. As noted, you broke off the tabs to encode up to twenty (?) characters. Each of the twenty rows of tabs encoded, in ASCII, the answerback or Here Is string. IIRC, Here Is was defined as one of the ASCII Cntrl+Character code points and receiving that code caused the answerback drum sequence to be read/transmitted. I think it was ENQ (Ctrl+E, 0x05). We figured this out and set up an answerback ourselves, but I have no idea to what we would have set it. IIRC, also, the DC1 (Device Control 1, encoded as Ctrl+Q, 0x11) /DC2 (Ctrl+S, 0x12) /DC3 (Ctrl+T, 0x13) /DC4 (Ctrl+U, 0x14) code points, for the ASR33, were used to start/stop the tape reader and punch. We also had way too much fun with Ctrl+G/0x07--rings the teletype's bell when sent or received. Good times…

Looks like you have to click on the actual text. If you click past the text, to the right, it does not work.
I tried everything, really. You see me click on the text and the space, on one occasion (not quite shown) I clicked on the arrow thing on the left and it worked. It is massively unpredictable and inconsistent, honest.
They arebt going to ban because 'bad people' use them. Instead, it will be because -good people use them...
You can give me where i can buy ?
I just ordered off Amazon I think, but I don't see a current listing. But just doing a web search comes up with www.waveshare.com/1.54inch-nfc-powered-e-paper-bb.htm
I need 😭
Suggest a shower curtain around that water stuff, keep future sprays off the electronics. Go Stargate go!
You should have shopped around! That is a fake deck that you have bought. The gift box is not genuine either, and the print is substandard.
That triac is most likely a copy of the original so 40A may not be possible. As rule, I assume 1/3 of the usable capacity of whatever printed on chips from China.
is that an invisible radiator under your bench? Do the macros need an external program to be running all the time? I need scroll-lock and like it to be the same place in Linux, Macos, Windows or some SBC
My boi prying with a knife.
Surprised you didn't go for blue switches which are clicky (and imo sound a lot better than buckling springs). Also, if you like the unicomp, why not just buy the pc layout one and swap the keycaps from your apple layout board?
Oh no hes finally outed himself as an apple user. My hero has fallen. Keyboard looks nice though. And I constantly kick myself for how many model m keyboards i binned in my early IT support days. Not because I have any fondeness for them but because of how much they ended up being worth!!
At 40 amps you better strap it to a water cooled heat sink .
Does this require any power sources?? If it runs on battery how long does it last
No battery. It uses NFC as a power source!
cheapones wont work with 3volts as the voltage drop from the status LED makes it drop under and not work
Anybody watching this video has to thumb it up. Purely based on you tore down an SSR for us.
It's a Vigenère cipher with an OTP. One of my favorite ways to use the OTP.
What is the "age check" at the top of the screen?
Flawless!
Your front gate is a double gate too. I'd be confused too.
Indeed, the sign has since been improved, and has a picture of the wooden gates now.
Think maybe you need to remove the block paving from your weed-patch... They'll grow better then!
LOL
What display did you use?
Waveshare 7.5" 800x480 e-paper on laminated glass
nice, and what cams do you use?
I'd have to go and check, I can't remember.
That's an interesting way to use e-ink displays! I never thought they would be genuinely useful for anything other than price tags, but I suppose signs would be a good use!
It is tricky - I mean I have seem nice weather displays, but like most things "my phone does that". The dynamic door sign is an example of a good use case I think. And, as you say, price tags. I did wonder about dynamic QR codes, i.e. a QR code you can scan but changes every minute so you can't re-use or use a photo, has to be a near live scan from the display.
I have a reMarkable clone (one with android and does colour), and it's been very good for productivity. Because e-Ink is not super high refresh rate and really only ideal for reading and writing notes, my distractions have been reduced down to zero and I find myself taking better quality notes. As for why I don't just use paper, it's because I am a disorganised guy and a piece of paper doesn't last 5 seconds with me before it's lost or destroyed
We have a huge problem with delivery drivers not reading our sign that clearly state "please knock once and wait patiently, WE ARE IN, disabled occupants so will take a while to answer the door". They always get impatient and knock twice, sometimes will just do a runner which with heavy parcels is a problem as both of us have problems lifting things.
I did consider adding a big countdown timer on the "we're on our way" sign to see if it meant they felt they had to wait.
They have a massive amount of parcels to deliver in a day. They can’t hang around every house with their different procedures.
@@gordonm2821So people who are unable to quickly respond to the door should just accept their lot? Delivery schedules should account for slight delays at each stop and we should stop being okay with companies imposing ridiculously bad conditions on their delivery drivers. Famously Amazon drivers have resorted to urinating in bottles in their vans rather than just stop because it puts them behind schedule. That's not only ridiculous, it's inhumane. Have some respect for your fellow human beings.
Well they don’t have to, they can come back the next day instead. I wonder which is easier for them? The sign helps ensure they know what to do in the circumstance. They don’t have to wait ages, ring again, then decide we are not in. They can see immediately that we are not in without waiting. So this is a big improvement on not having a sign.
I used a dc version of this on my ebike so the 5v alarm circuitry could switch the 84v battery for the motor. bit of overkill as I suppose I could have used an optocoupler and a P channel fet, which no doubt is all that's inside what i bought
What do you do if your extruders are not heating properly
I have one similar to that. Works well as a 12v DC relay. I'd forgotten I had it, to be honest. Right now I'm using two mechanical relays to run my 120v AC 20 foot long morse code flashing penis.
I worked for Barclays in the City of London in 1988 and there was a teletype machine in my office, with a dedicated operator. Nobody else understood how it worked. Thanks for explaining.
Hi, so this is great work. Currently I am completely new to programming etc, and I would like to know if it is possible to just have the code, to put it in an Arduino for example. THANKS !
All the code is on that GitHub link, as well as the PCBs. It is C code in ESP IDF, so no idea if it ports well to actual Arduino.
@@TheRealRevK Thank you, I'll try to look into it, at worst I'll have to buy a new card. ^^
You should do a Pegasus gate. The static gate coupled with LEDs racing around the gate would go quite well.
If only they're was a shuttle to go with it ....
Cool. I'm gonna put the other star gate on the kitchen counter, next to the Doritos.
I would love to see this on a repository like Printables or even on Instructables. Hint, hint, wink, wink!!
this is cool bit i feel it would fit the atlantis style gates better sine the gate didnt spoin my the singular lit constellation spun to the correct one when dialed. also 5/10 still havent dismantled a toaster for this
5/10 no toaster
I'm waiting for someone to turn the stargate into an actual communication system
Just curious if you would ever want to make one to sell? I would love to have one of those on my desktop.
Not ruling it out.
@@TheRealRevK if you decide to sell them let me know, I would definitely be interested
Nice would love to see if you can use some sort of printer to use more black plastic as Gates were obsideon black. But clear where needed?
