I see my vtech unit has the mini antenna also, but how do i identify the antenna pads? It looks like the antenna is soldered to two pads, how should i figure out how this should be soldered?
True that, not very clear there
Hi Andy
Thanks for the video
I am planning to do the same with my vtech
Can you please advise if I use your idea but instead of fitting antenna directly to camera I would like to extend it to outside of the building and put in in my balcony so I can reach to the end of the garden? I understand the cable can not be too long . Can you please advise where to solder the second cable . I understand one to the old antenna and second to earth ?
I do not want to break it as its new ;)
Thanks
Thanks. I don’t have a baby either but there’s no harm practicing 👍🇦🇺
I did this to a vtech unit and actually lost range. I'll be soldering back in the original antennas.
I have one I can't fix it I wonder if you now how
Does anyone know where I can get a replacecemt screen for this monitor? screen part number LZTFT350A-03
I cannot find the antenna on my Motorola Mbp855, any tips?? Tks
It might be on the PCB, look for a 1.5inch copper line on the board. Email me a picture if you want.
@@andykirby Tks will open it again and take another look inside, what is your e-mail?
I took apart my new camera today. So apparently the antenna is really embedded on the card. It's the thicker copper wire we see on this video? th-cam.com/video/zGsMKEwCqkU/w-d-xo.html
This is awesome! This is so close to my new model- but mine uses FHSS... Will this technique work for mine?
Yes it will.👍🏼
wHAT THE FLUX
i have a non Wifi baby monitor supp 2 go 1000 feet, i'm using at 200 feet and it goes out and yes.. lots of items and things it has to go thru. Can i easily improve the antenna on that or is there a "stand alone, in between antenna" I can erect betwn viewer and camera? ( you can tell I"m not a techy) Your vid was good thanks I guess all things are possible
hi andy, my battery is weak. ho do you dissamble the parent unit, to replace the battery?
and also. the original battery is 950mah, can i use 2000mah?
Just bought one cheap off ebay, pivoting aerial broken on monitor, wire aerial inside plastic casing frayed and soon snapped very close to pivot point/hole so had to get it apart. You're right, they are difficult!
Remove all screws. Beginning at the power input end gently lever with a screwdriver in the joint, working way round I broke one of the tiny moulded catches.
It is actually RP-SMA female connector right?
Is there a video to tell us how to fit the coax cable to the sma connector and then split the cable in two parts, the center piece should be fine but not sure about the outer one. Seems you got it readily available but can't seem to find this online
Looking for the full video of this. I feel like I've seen it before, but can't find it now.
Don't leave baby in the workshop.
hey fellow radio amaturer ! good job . btw . Im also in the process building a 8000watt ebike. and looked at you website for info and things to get , only have the frame for now and have many questions regarding the build which motor is best for my goals qs205 /qs273 and so on . thanks for great tube videos. oz2tkn
For the antenna cable that will go to the SMA, you solder the central pin on one end and the shielding on the other end? Anywhere on the copper cable on the board should be fine if at each extremity?
Earned my sub. Great video!
Removing the front cover of the screen is easy, it just peels off and behind are the access points to the screws. I’ve taken mine apart for this exact same reason. Great Vid!!
Where's all the vids Andy, Need to get that Ebike out soon and get some uploaded
Great video. Love hacks and things like this. You could make the cheepest drone with 4k camera or something by attaching a small battery to a cheep drone and altering the antennas and stuff to get maximum range. I know alot of people modify controllers for drones to acheve grater distance. And also drop hatches ive seen on the drone. Where you can deliver stuff and drop it at the destination. Again the only issue usualy is range. Regards bro nice vid.
Are you guys having a baby?
Great ! I wish that the monitor had outputs for a larger screen or for recording ! These are great for supplementing security camera blind spots. I use for watching chicken coop and as a deer cam.
Yeah hdmi out or an sd card recorder would be cool!
I could appreciate your help on a different subject,
What size battery would I need to suit my kit the hub is a 48v - 1000w can't get any answers where I live ( pretty please ?
Hey, I’d recommend a 16-20Ah battery. We actually sell a powerful 17Ah one in our store here: www.cloudsto.com/ebikes/batteries/lithium-battery-pack-52v-13ah-ts-detail.html
I agree with Andy, you should be able depending on your riding style be able to get 40Km worth of assist on a single charge. This depends also on temp and terrain, I could average 40 to 50Km in assist 5 with a 1500W setup and a 13Ah battery, but that was my battery maxed out. If you can go for a 20Ah having more than you need means less charging of the battery,.
Get yourself near or close to 20Ah and something that can give 15+amps continues you'll be good
Nice one Mate! Have you had a look at any of my recent vids yet? been out a bit on the bike....
Not yet, I will have a catch-up!
Bet the SWR is a mile out.
As always very interesting :)
To change the subject, here's a nice looking Twizy
th-cam.com/video/BSGyl7Ss-30/w-d-xo.html
Ah yes the Oakley design F1 replica. Looks great doesn’t it.
@@andykirby For sure, just imagine it with a bigger motor.....
Yes it needs it to match the looks! It does have a powerbox though and that makes it very quick 0-30mph. I’m still looking into ways to make it faster mid range, probably much higher voltage is needed😁
Would a 3dbi antenna already help for use inside an apartment (750 square feet) or do you believe I need something stronger? Tks!
Yes 3dbi will give you a nice bit of gain. Make sure the antenna is not on a long cable though as that will introduce other losses.
@@andykirby Thanks, will use a short cable to do the same as you did, put the antenna right outside the baby camera. I just received the antenna and cable this afternoon.
Flux, flux, flux.
That was a good one Andy cracking idea.
Cheers mate!
Hi Andy, thanks for the video. I would like to know how do I find the other spot to solder the antena plug in? On end is where the antena itself was soldered on and what about the other?
There’s usually a bit of wire about an inch long, remove it and solder the center of the coax to the same point. The ground (outer coax) goes to a ground point on the PCB. Usually there is nearby and it looks like a solid plate on the PCB, all PCBs have areas on the board which are grounds.
@@andykirby Amazing! Thanks a lot for answering my question!
where are you conecting the 2nd wire? is it ground
Yes ground
@@andykirby thank you
can someone help me please. im finding it difficult to understand how the SMA cable was split into to wires? Can someone send me a link please to the correct label as I need to do this mod myself. Thank you.
Please check this video, shows how to do that. I´m now just unsure where to solder the separate wires on my board.
th-cam.com/video/BUFsaYFX7HM/w-d-xo.html&lc=z22hwzcb0resgv0ugacdp433s1cy25j5bho5d3olkohw03c010c
The solid strand of the SMA connector goes to where the original antenna goes and the stranded wires is the shielding so that goes to a ground (the golden round pad on the board)
@@patricks5575 thank you!! So basically if I remove the insulation around the SMA cable, the part to solder to the ground it is the white shiny sheet around it and the middle cable gets soldered to where the original antenna was?
@@savitu12 thanks this was very informative!
any more ebike vids
Yes got some planned👍
I would prefer to fit the antenna on the receiver to make it more sensitive, rather than increasing the Effective Radiated Power at the transmitter end - that is, if it is to be used to monitor a baby.....
Very good point 😀 of course I don’t have a baby so for what I’m using it for it should be alright.
Actually, thinking about this more it could make it safer because you could route the point of radiation far away from your little one by using a run of low loss feeder, the antenna could be in another room.
It will be pumping more power to the antenna if the signal is weak. With a big antenna you will be good with less power.
Having a high gain antenna is good but careful it will be emitting more mw of power that could interfere with wifi, I second using a yagi antenna or parabolic antenna on the receiver to gain the collected signal. But fun to play with, bit worrying they are sold for baby monitoring as any 2.4ghz rx in range can view the image I had a reversing wireless camera on my car that had a screen in the rearview mirror and I would have random images show on it when I passed though towns and thought that they should be better secured.
Hi Andy nice to meet you mate I found your channel a few weeks ago find some your stuff very interesting but the electronics goes way over my head anyway I've bought a bike 1200 volt and I've got a battery for it that's 48 volt 17 amp hours what range should I be getting out of it I was told 50 minimum but I'm only getting 25 is that saying right
Sorry 1200 volts
Hi! 1200 watts I think you mean, 25 miles sounds about right from a 17Ah battery. You’ll probably get closer to 35 miles if you pedal hard as well but who wants to do that 😁
That was Pedley mate
And thanks for your quick reply
Range can depend on a lot of things: bike+rider weight, terrain, average speed. 25 miles doesn’t sound too bad for a 17Ah battery. If it’s getting hot though then it might not be powerful enough.
Hi Andy, I really need to know something Andy! How is the bosch battery, what's the top speed, what's the range? Please answer.
It seems to me that the instinct of the mother begins to work towards the child. It is difficult to explain, as far as I know, scientists could not explain this phenomenon. Instincts are nice, but they will not always be able to warn that the baby is not okay. I would still recommend using a baby monitor, for example, with access to a phone or tablet. So mommies will always know that everything is fine with the child and he is sleeping sweetly.
My system´s frequency is 2400MHz - 2483.5MHz with 17DBm transmission. May I use any 2.4ghz antenna on it? Thanks again!
Yes the 2.4Ghz antennas are usually good for the entire 2.4Ghz band.
Hi there. Thanks for this. I tried it out and the range seemed to have dropped significantly
Reverted to original antenna and range is even shorter.
Do you perhaps know why this may be?
Check the connections and soldering. Use a magnifier to identify tiny solder bridges.
This is actually quite helpful. I just bought a cctv setup with 4 wireless cameras from Ebay and wasn't expecting much tbh. But it's actually very good, really happy with it. The only thing is the range of the cameras which I'm planning to improve in the same way as you did. And also it's really messing with my home internet wifi. It's really quite annoying! I'm planning to move the received box to the loft and maybe play around with the wifi channels. My wifi is 2.4ghz and I have a repeater as well. I'm suspecting the cctv is also 2.4ghz. Any advice?
Hi Kris, please can you email me at andy@cloudsto.com we might be able to do some business together.
Thanks Kris, but I'm alright. Probably wouldn't work so well as a security camera :)
Sounds cool, do you have a link? It’s not good it’s messing with your WiFi though, I suspect it’s taking a massive chunk of the 2.4GHz band to run all the cameras. Do they specify the power output in the manual? Or maybe there’s a way to move channels. With a lot of 2.4GHz stuff around the band can get overloaded that’s why they started using 5Ghz but it doesn’t penetrate walls as well (and 2.4 is pretty bad to start with)
@@andykirby Yep - www.ebay.co.uk/itm/Security-Camera-System-Wireless-Outdoor-1080P-HD-8-Channel-NVR-WIFI-Night-Vision/392263057222?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
Yeah, 4 full HD cameras streaming wirelessly probably take a lot of wifi bandwidth. It's clever enough though to detect what channels are not as busy and automatically selects them... Walls is exactly the reason why I'm using a 2.4 wifi for the internet at the moment. Ideally I'd like to improve the cctv camera signals too. Do you recon I should upgrade the camera's wifi antenna or the receiver's antenna instead?
Looks like they all have external antennas, can you just unscrew them? It might be worth using directional panel antennas on the cameras so you can focus a beam of signal from the camera directly to the receiver, and then have the receiver away from your home network so you are effectively limiting the RF everywhere other than where it should be going. It might be tricky to get it all lined up but that’s what I would do. You could keep the omnidirectional antennas on the receiver or connect up an omnidirectional outdoor antenna, but keep the run of coax below a 5 meters as you lose a lot at 2.4GHz.
