"and I found that blowing on the chip makes it run faster"
*blows on potato chip*
*wave goes to the right*
I laughed way too much at that.
"blowing on the hot potato chip"*
lmao ikr somehow that's funny
right is faster, left is slower... well, let me ask my wife what she thinks. :P
Potato... chip. Oh, I get it.
I didn't get it until I read your comment. Thanks. :D
Oh, yeah, I had to google that too, because I am not a native speaker. "The dad joke is a pejorative term used to describe a corny, unfunny, or predictable joke, typically a pun. Generally inoffensive, dad jokes
are traditionally told by fathers among family, either with sincere
humorous intent, or to intentionally provoke a negative reaction to its
"dagginess"."
only works when bought in plural
Also, a 'potato' is a nickname for obsolete hardware, thanks to the game portal. It is a brilliant name in multiple ways :)
And old computers and electrónics are usually called potatoes, or toasters, so its a double joke :F
You made a TCO = temperature controlled oscillator. A pretty sophisticated way to measure temperature.
Debraj Deb he made a taco
yes
nerrrd

*HUGH MUNGUS* Inc.
Humongous what !? :D
@@PainterVierax Ink obviously. Be a great name for an ink supply or paper good company XD
@@joshuarichards2421 I think you totally missed the reference of the joke at the time it was written.
Mungus
Sus 😳
Leaving the unused pins open may be contributing to the instabiliy & power draw
mikeselectricstuff I was thinking same thing
Gotta ground them hex inverters!
I always forget to do this every time as well. Spent far too long messing with a NAND based memory cell till I realised not grounding the inputs when input switches were open (hence left floating inputs) was making the thing go nuts.
luketorpedo yeah. Leave no pin floating unless the data sheet explicitly says leave disconnected. In which case, pad on the PCB. Nothing further.
It's a good lesson that all EEs. Hobbyist or Professional, eventually go through. The world is full if EM noise.
Not may. This is 100% the reason. Floating pin = major increase in capacity.
"You could make a short range bluetooth jammer... But I'm not going to show you that."
Aww, darn. Take all the fun away. :P
Laughed out loud when you blew on it to speed it up!
Thanks for showing this company - I'm working on a 74xx CPU design right now and this is perfect for updates I'd planned for revision 2!
if you that i instant sucribe your chanel but at least run it at 100mhz.
Gotta walk before you can run!
Currently I'm using standard 74HCxx parts on a breadboard. Couple of kHz, max. I just finished wiring things, if you go ahead and subscribe you can follow the progress ;-)
If you don't already know his channel, you should check out Ben Eater. He got a (soon) complete, freakin awesome tutorial series on how to build an 8-bit computer with ICs only.
kHz? Is that limited by the breadboard? Because 74HCxx can run up to 16-20 MHz.
GRBTutorials the breadboard does significantly reduce speed.
Also, the 74HC series can run at 20mhz on their own, sure, but once you string dozens or hundreds of them together, your critical path is no longer 50ns...
Now I'll just wait for Tomato Transistors and Cucumber Resistors and Sausage capacitors!
hehe
Well, I'll pay 1$ for Bluetooth jammer video:)
I'll pay 5$ for a bluetooth jammer video . . . although, bluetooth is mainly on 2.4 Ghz, if you found out how to keep the frequency at 2.4 ghz, you have your bluetooth jammer right then and there. . . . (just don't get in trouble with the law)
The FCC (if in the States) would like a serious conversation with you.
Either isolate the 2.5Ghz harmonic or make it run faster (blow that potato) and maybe amplify it :D add an antenna and done. dont forget to bake some potatos on the hot chips :P
Richard Skyephotography okay..
2.4ghz?! Wouldn't just using wifi jam Bluetooth?
so you can make an actual potato computer ;)
Who's going to be the first enterprising Tuber dad to build an enormous potato battery to power one?
genetically engineer potatoes to be more acidic.

While overclocking just make sure you don't fry... the chip
Thank you sir. I've been waiting for these for years. The 7474 analog is a great little part for my SDR project (for a quadrature divider). At $2-$3 these are hot little potato chips indeed. :)
"Naming your company after a dad joke is a great idea."
Because i'm a potato!

Brian M. Portal 3 Confirm!!!
I can hear the exasperated autotune voice.
God, now I want to build one of those 70's era diy cpu kits out of this ttl logic.
Back in 1986, I used to call Radio Shack and say "Hi, I wanted to know if you have an RCA CA-3080 transconductance operational amplifier potato chip?". They'd ask me to repeat it a couple of times, unsure if I actually said "potato".
I was a legend in my own mind.
You can limit the effect of your o-scope by driving a 4th inverter, and taking the output from it.
This is still one of my favorite TH-cam video lol
*Fun Fact:* There's a potato chip inside the SEGA's VMU.
1:40 The construction of the circuit is actually quit good if the decoupling cap is located where it should be (but that's something you'll know about). A dead bug style circuit can have very low stray capacitance. The property you want for this type of circuit.
I made some sort of FM transmitter using the cd 4011 in the same configuration , never understood very well how it works , but i guess the FM modulation was done by the same oscillation instability by self , 20 years ago nice memories BTW and video ...
all the love for this video!
**Listens carefully and occasionally nodding in agreement**
(Meanwhile inside my head) "I have absolutely no idea what this tech-wizard is talking about (。ᴗ°)"
Holy crap! This is really useful
+Afrotechmods hey mate thanks for this vid, would one of these ICs be a good option for high speed voltage level shifting? I think some of their gates can run at 5V so that output high can be 5V, and use 3,3v input high
Dear Afrotechmods, Always brilliant videos aimed directly at the subject at hand. No look at me, look at me videos where the author seems to believe his face all over the video is good! Good clear voice, designed inform those new to electronics yet not boring those who are experienced. Keep up the good work your only rival I have found after much searching to date is "Great Scott". You both have great styles and must both be offered the honored title of Guru, Shifu or Sifu,,,,Master! Well done, Respect!
Nice! Good to know about those Potatoes chips :) Thanks!
TH-cam recommended
well that was educational.
I'd be glad if I could see a quick tutorial by you on what exactly all this means...
Thank God for this video
I understood about nothing you said there, but I’m really interested! Where would you recommend someone start learning about this stuff? Where did you start out?
I just tried the same thing with a 74hc chip. It works just the same as you would expect. But it also works with only one inveter which has its output connected to its input, what results in a way higher frequency than with three inverters in a row. Have you tried this out too?
Your blowing skills works as frequency changer. :D
pretty interesting chips, thank you
Careful how you solder them, unless you're okay with lead in your Potato chips.
I feel like I need some Potato Chips now.
So... was one of their processors use in the Dreamcast VMU?
Man that was fun! Thanks :-) Now... how about inductively coupling it to an LC oscillator for harmonic selection and a BFR90 PA? :D
Thank you for sharing this video
So essentially what you've made there is the world's most unexpectedly complicated, digitally readable thermistor?
Show us how to make the blue jammer 😂😂
Your the greatest teacher I've ever watched teaching with a side of jokes 😂😂
add capacitance such that one of the harmonic is nearly equal to 2.4 GHz and that's it.
I want to see what this thing can do with one of those little IC heat sinks glued to it!
potato semiconductor. thats amazing
para ahcer un oscilador así tenés que usar un schmitt trigger, además debes usar un chip de salida para aislar la carga de salida
Spread-spectrum jamming is easily achieved with FM using a tunnel diode, varactor diode, and class-c amplifier. Totally analog!
How badass would it be to have a quad of 4 bit 74181 4 bit alus and 182 carry lookahead generators? With those two and the other chips already offered by potato, one could (assuming one can find some very fast proms) literally build their own 1ghz Vax 11/780 clone right down to the chips. I ask again: how badass would that be?
Hello, I have a simple regulated box mod power bank or power supply for vaping tanks. It has a voltage cut-off chip that turns the device off after only using .8 volts of the battery power. I want to put another chip that gives it more time before turning itself off. It is the tesla invader three. How do I distinguish the cut off chip and can I replace it without pissing off the " internal blink when something isn't right" chip?
Best conclusion
Far as I can tell here, I believe those harmonics you are seeing would be down to the actual signal being generated being a square wave. This is pretty clear by every second multiple of the fundamental frequency having a higher spike in amplitude which summed make a square wave. I'm not sure why there are smaller spikes between, but they won't have much effect given a small reduction in dB is a huge reduction in signal in real terms. I would guess the low bandwidth of the oscilloscope in comparison to the 2nd harmonic is probably why the scope is outputting a sine rather than the square wave the signal analysis suggests is present.
I just can't find any places where would be possible to buy some of them chips...
but can it run crysis?
*points at the door while shaking head *
what if you used these to make a discrete computer?
Ive seen those made with discrete transistors but those arent near 1ghz speeds by far.
I have been looking for this channel for 5 years
+8 subs
could you explain more about how these chips are redesigned to run at modern speeds?
I put that company's webpage in my favourites list, just because it's called Potato. Well done, lads.
TIL a new term - "Dead Bug Soldering". Hysterical!
Words I understood: Circuit, Potato, Chips.
GENIUS!
so? What's the advantages to produce high freq. with this chip. Can someone explain?
Potato chips, genius!
2:01 Please show us how to do that, rather than telling us how to do that😁😉
I think youd need to isolate the frequency, amplify it a bit and make a transmitter. I think either or a combination of a RF Filter, Low and/or High pass filters. never tried, but I know its posible and if you try it localy, with a tiny amplifier so within 10 menters youd jam, it probably is allowed as "research".
Note that bluetooth is on 2.5Ghz as Wifi is aswell (later wifi is also on the 5Ghz. ) jam those and your sure some device cant talk good anymore. I might be wrong tho, im not a licensed radio amateur, just an electronics enthousiast
@ STU-Christian Its not illegal on private property.. But you gotta keep the bleeding in check so it does not go off your private property. Once it effects public areas is when the FCC will fine you if you are reported and they can prove its bleeding off your property. Plus I already know what he's talking about. But I as well, wont tell.
Excellent!
This channel is the coolest.
I'm eating app ordered pizza,I'm from the future too...
Hmmmmmmmm........ I'm gonna have to check their sit out. I want to know what they all have. :D
Undefined potential on the unused pins and no heat dissipation. That should be the main source of the instability!
Maybe try it again when soldered in?
Can you please make the latest video about electrolytic capacitors avaliable for all countries? I am prohibited to watch it...
Flankymanga get a VPN if that doesn't work use for network
Potato Pototo. Good times.... Good times.... 🤗 Thank you for the brain food.
I wish someone would do this with old MOS chips. It would be fun to have a 1 ghz 6502. lol
I wonder if these could be used to make a high speed version of a 1970s mini computer?
can someone tell me how to build the bluetooth jammer or is there any information on this subject?
Why am I binge watching this even though I have no idea What this is
"And no, I'm not going to tell you how to do that."
And the FCC rejoiced. Selah.
we need more potato! lol
Does the company also make TH-cam cameras?
Can you create a Gameboy on steroids at 1Ghz?
(Maybe an HD or 4k gameboy)
Very COoL. And I though a potato was just a potato. Add the Chip and.. :)
It woukd have been interesting if you told us how to thworitically make that iammer. Would be so educative. Because its simply from a cheap 74ic. Pls condider
- Hey, let's buy some Potato's chips?
- Great! I'm hungry!
- No... Not THAT kind of potatoes...
Thought from the title , potato chips (lays, etc) were conducting
What signal is it generating?
Try receiving it with an sdr
Conclusion: Blowing over hot potato chips make them faster!! 😂😂😂
I'd really love some potato chips rn..... (to solder)
I clicked on the video thinking you were going to power a computer with hot cheetos or something
I dont know why I found that so funny when you blew on the chip and raised its output freq LOL just blow to get your freq on... I'll see myself out now.
Oh wow
title made me hungry
How bright will it burn on 50V?
I thought this video was going to be about actual potatoes used to generate energy.
Welp I'm off to jam a bunch of people devices around town xD
If someone steals one of these chips, does it become a hot potato?
i would like a bag of potato chips
motherboard hack, using that chip to boost cpu performance (overclocking)
Can i eat them? Are they with less-fat so they are more healthy???
pls tell me how to do bluetooth jammer! :D
For everyone else on planet earth, CRISPS
Can it run cpm or unix
that ending tho.
I would love to see your newest video because it would probably answer so many questions about caps in switching DC-DC PSUs but its unavailable in my country, i would pay to see it, in fact, i turn off adblock when i watch your videos because I've learned so much from them, this just sucks...
Check your youtube private messages
now the joke 'atleast /i/ can overclock my potato' is a fucking reality
Legal saber que ate batata e mais poderosa que meu nootbook!!
Is this the company that also makes all the CMOS sensors for really bad cameras?
