I must say I am really enjoying the sort of "show piece video" followed by "behind the scenes/details video" format. I know you have done this stuff before as a channel, but it's amped up a bit recently and I enjoy this a lot.
I had to do something similar yesterday to try and figure out which cat was peeing in one particular, somewhat hidden area of the house. I took my Pentax K5 and took apart the remote to figure out which pads activated the shutter, and in turn, hooked that up to a relay, an infrared sensor, and an Arduino Uno. That worked beautifully, but now I need to figure out how to overcome the cameras power saving features, and I think I'll just have to tell it to take a picture every 5 minutes or so, and I should have the culprit. I was incredibly surprised how easy it all was considering I'm no more than a novice. Oh, how I love this era.
You did a pretty good job doing this hack. Only real thing I noticed is that you used wire that was way bigger than needed. Next time consider using a chunk of ribbon cable or even Wire Wrap. The current needed is in Milli Amps and fatter wire just gets in the way. It is good you only had on/off functions to deal with. Analog functions could also have been dealt with by using the PWM output function from the Arduino to bias a transistor to the desired output. There are also many other methods but considering the input/output limitations on the Arduino PWM would have to be used. In industry we would have multiplexed the data stream and used 8 bit resolution. Since there are only 15 buttons a 4 bit address or 16 Byte data stream would be all that was needed.
+Mike Paquette Yea, I get that. But assuming that someone knows Chinese or what Chinese looks like, just because they look Asian, was the punchline. I get that he probably knows what Chinese looks like.
+Comeback64 The only language that comes close to looking Chinese is Japanese as Japanese ( Kanji ) has been derived from Chinese and even though I'm not able to read Japanese I sure can tell the difference between them because of the also always present and fairly easy to learn Hiragana/Katakana that is present in Japanese writing with one being the General form of writing ( think of it as handwriting ) and the other being used to "Japanify" foreign Words ( think writing a DAIMLER BENZ in capslock ). Chinese on the other hand is all that complex "Kanji". So maybe even with Norms look this might have been a totally casual question.
It is a great demo for hacking toys, I want to do the same thing, and program my toys. Would you like to share more details for me. e.g. what anduino component it needs. and circuit diagram. Thank you.
to Tested: some videos only output audio from my central speaker, that means that while i wear my headset those videos don't have any sound, just telling you because it may be something no one told u yet
Is there any way of hacking analog joystick buttons, which have potentiometer attached to their wiper?. I'm trying to control my RC helicopter with Arduino.
Usual trick with 2.4GHz stuff is to intercept the communication bus between the processor and the radio transmitter. Not sure if it would be possible here or not though.
+Brad Barlow Agreed. It actually is the most common. To anybody else, the 27 and 40MHZ is very old school. Everything is moving to, or has moved to 2.4ghz. If you see anything with 27 of 40mhz, it is at least a couple of years old.
+Brad Barlow For toys MHz is the most common radio signals, for hobby/scale RC cars 2.4GHz.. The reason it's atypical is because of a multichannel RC system like the one above you'd think they'd keep the cost down by using old technology, especially since this thing would be used at very short range so a 2.4GHz RxTx is pretty overkill/redundant.
Doesn't JPL have a duplicate rover in a room with red dirt where they actually and accurately test movements before sending commands off across space & time?
+Pritpal Desai Are you kidding? They said it 3 times in video, why he did this. It was for JPL Live show for showing how Mars rover is controlled from the Earth...
Next project: Put a camera on the tractor that sends picture back with __ seconds delay. Then go full command centre. Oh! internet controlled Tested rover!
+John Ridley You are way overthinking it. Just because the radio frequency that it transmit over is 2.4Ghz don't mean the actual communication inside the controller is that fast. Normally its I2C or a PPM based communication and both those are well supported by the arduino. Just connect the arduino between the PIC or ARM inside the transmitter and the TX module. Total cost for that would be one arduino and maybe a I2C lever shifter if its arm since arm normaly use 3.3 V and not 5 as the arduino do.
+John Ridley Would need some testing with a logic analysator to check just what it is. Most likely it uses one of the standard well documented chips such as nrf24l01 used by vltoys, hubsan and a lot more. Still it is between the controller (PIC) and ANTENNA and it's method of using a delay wich both fits of what he wanted to do.Still if you actual want to connect on the sma connector and have an antenna after re-purposing some thing as a wifi repeater would be a possible solution. Or any thing else basicly with 2 network cards. But then it would just be easier to make a he said in the video. Change the receiver inside the model and just buy any reciver that have a traine port and connect this. www.readymaderc.com/store/index.php?main_page=product_info&products_id=285
Hey , I wanted to make an rc plane, but the transmitter and reciever in just out of my budjet...so is there a way I can reuse the transmitter and reciever in my drone..for my rc , rather that throwing it into the trash..?? Could someone help me , to make an rc plane is my dream from 7th std but now am in 11th .. then and now money is the biggest problem..??🙏🙏
Meh, seems lazy for the editor of the video not to at least put an overlay with his twitter handle in there, AND they didn't put his twitter handle in the youtube description. So I'm just supposed to guess how to spell what he enunciated?
They a NEVER put any links in the descriptions. Even when they interview someone, who isn't a Tested cast member, they don't include any info on how to look at their work or contact them. They don't do it for products either. I don't get it. They were talking extensively about a product a few months back, and the way they were saying the model name/number on the pod cast, it wasn't clear and I couldn't quite make it out. I tried googling a bunch of stuff that sounded similar to what they were saying, but wasn't able to find anything until I read through the comments. Tested, please put pertinent info in the description!
+Katojana Aleksielsis Well with this principle you could put computer interfaces on any RC gear without redoing the entire RC part for something unknown.
I did something similar with lego power functions.... Because mindstorms cost is too damn high! (poor college student) I even did a 3d printable lego mount for the Arduino mega. It is on thingyverse now.
+Brad Barlow I think he meant it's not using any typical protocol that is used for rc cars. 2.4Ghz is just the frequency, you can have diffrent protocols for the same frequency. That is why you can't use a transmitter from Futaba (FASST protocl) with a reciever from spektrum (DSM protocol) but they both use the 2.4Ghz frequency band. Some of the procols have premade modules you can buy and this is what i think he was hinting at.

Any video with Jeremy talking about some electronics he has made gets a thumbs up from me!
Great video

"Does this look Chinese to you?"

+James J Who Jeremy? I don't know if it was as bad as you're making it sound. It was most likely a slip of the tongue.

can you guys plz test a kodak 360 camera and can you make a full 360 camera using 2 camera ?? can u plz make it ?
please code?

i have this RC I'm looking to make it Receiver like futaba. how would i go to make it work
2:02 *"the tractor doesn't even know that I am interfering"* Oh great tractor has ability to think and reason than :D
Run! It's slowly becoming self-aware! XD
npn, or pnp transistors?
This is fantastic but there must have been a more elegant solution. Idk, great video.
Usual trick with 2.4GHz stuff is to intercept the communication bus between the processor and the radio transmitter. Not sure if it would be possible here or not though.
+sample text Well i would assume now the system works you could make up a PCB mount it in a controller casing.
2.4hgz ... Then he says not a typical rf signal for rc cars..... I'm done (it's the most common). Tested is getting dumber by the episode
+Brad Barlow Actually the typical rf signal for a rc car is 27Mhz
+hudson holt 80% of the RTR cars on hobbyking are 2.4ghz
+Brad Barlow 27 and 40mhz are used also very often. Is "80% of Hobbyking's RC cars have 2.4ghz" your source of "Its the most common"?
+Brad Barlow Agreed. It actually is the most common.
To anybody else, the 27 and 40MHZ is very old school. Everything is moving to, or has moved to 2.4ghz. If you see anything with 27 of 40mhz, it is at least a couple of years old.

Basically you have made a Big Trak, a toy I played with in the 80's.
+Darren Turner Exactly! I actually suggested that to WIll but he wanted a tractor. They sell a remake of it on Amazon.
+Jeremy Williams LOL I know, I bought one for my kids 😂. Have to admit, I had a good play with it too.
can I get a English version of this
Sooo.. You dont control it with the arduino at all.. You are just making the arduino delay the signal. Wow.. very inpressive. Not.
Erwin Holland Why overcomplicate it
Cool vid. Now I need to make a trip to Radioshack.
*asks Asian*
"Is this Chinese?"
"WELL NO FUCKING SHIT"
More Electronic videos please!! very cool
Hey comment section: way to miss the point.
What was the point of all this? Why couldn't he just play with the digger?
+Pritpal Desai Are you kidding? They said it 3 times in video, why he did this. It was for JPL Live show for showing how Mars rover is controlled from the Earth...
Next project: Put a camera on the tractor that sends picture back with __ seconds delay. Then go full command centre. Oh! internet controlled Tested rover!
really nice and funny project, thanks!
why not just add a delay/buffer between the controller and the antenna? wouldn't that be simpler?
+John Ridley You are way overthinking it. Just because the radio frequency that it transmit over is 2.4Ghz don't mean the actual communication inside the controller is that fast. Normally its I2C or a PPM based communication and both those are well supported by the arduino. Just connect the arduino between the PIC or ARM inside the transmitter and the TX module.

LOL Jeremy was Sid from Toy Story.
Super rad
From a technical standpoint... great.
But... why?

Well with this principle you could put computer interfaces on any RC gear without redoing the entire RC part for something unknown.
Those of you in the comments, what strict definition of "hacking" do you follow?
