@ECEtek14 күн бұрын
With mine the securing points for the springs that formed part of the walking action had broken away from the chassis of the toy. There was no reasonable way to fix them. Glue wasn't going to cut it. I was lucky in that I had two items with different issues, so I was cannibalise one to fix the other. It isn't hard to get the legs off to have a look If it is unrepairable you are probably only going to put it in the WEE waste anyway. Worth having a look - should only take 10-15 mins. If it isn't fixable - at least you know! Thanks for watching the video.

@ECEtekАй бұрын
You can either use another Matthew Walker (as these tend to 'walk' toward the loose ends it is useful to make the braid a little 'tighter' just before it finishes so you can then take up any slack that the knot introduces) OR you can 'whip it'. See my earlier videos ET#28 and ET#34. These introduce whipping the transitions and stripping out the inner strands from the paracord. Thanks for watching.

Good to find these two videos about this battery. I had bought a pattern battery and before even trying this replacement I went to "jump" the old battery by connecting negative to negative and positive to positive in the hope that the little extra voltage would was all that was needed to get the battery charging, being hopefully above the threshold for the requirements of the charger. I screwed up and connected negatives to positives and fried the brand new battery. So much for me saving and repairing, I ruined one. I have seen new boards for sale from eBay. Do you think that maybe replacing the blown resistor on your battery BMS would have fixed the fault or is a known fault code response? Many thanks and keep trying.
@ECEtek2 ай бұрын
Ouch, an expensive mistake there mate! Easy to do though. Might be worth stripping the batteries to see what the issues were. Make a video and let me know when you post it - I'll watch it to see what went on. You might be able to make a good one from the two - or at least salvage the LiPos. Unfortunately I didn't know the history of the battery I had - so I don't really know what caused the resistor to blow in the first place. We can assume it was a pretty big current surge that would cause that amount of damage. Unless it was possible to identify what went wrong it would be hit and miss on whether replacing the damaged component would fix it. If the underlying root cause was unknown, it could just blow again in exactly the same way - or it might work fine. I could have opened up the good battery and hoped that the same BMS had been used and so identify the correct component for replacement purposes. We don't know what other issues may have been caused. The blown component may have acted like a fuse and saved everything further downstream - or not. My need for a spare wasn't urgent, so, for me, not worth the effort or time to replace it (and the tracks etc that had also gone). Thanks for your interest and time taken to comment!

What's the knot surrounding the fingerknot (with the green string)? I'm currently learning to make these, am on my third, and I have started weaving my pouch strings into the sling as well like you talk about. My reasoning is just that it makes the pouch and down strand heavier (figure better to sling with) and possibly more secure. With my first sling didn't though; am currently unsure how big of a difference it makes so will keep experimenting). I have innards of threads from making the adjustable finger loop design of Blind Squirrel so will be trying your whip cracker design. 👍 How do you feel slinging with an open/loose loop works? I have seen a few people do this whereas I so far have only used aforementioned double-loop singed up really hard. Edit: also learned the MW-knot but was told by another guy that it was difficult to get it close to the braid (would leave loose string). The knot was easier than people made it out to be butt still haven't tried it. Difficult to get close to the braid without leaving "open" string? Edit 2: I have so far only made 4 strand versions (2.5 complete ones with a few failures and am getting the hang of it) with smaller pouches, because in the future I would like to hunt rabbits with them stealthily using clay ammo, but am now thinking of a tennis ball version 6 strand one for dogs (have seen a 5 version). Thoughts on that? Too thick or still flexible enough to throw well? 4 strand "good enough" for a dog fetching (a terrier or some other "don't quit" breed)? Edit 3: ah this is a round braid, I only made flat ones, advantages with this?
@ECEtek3 ай бұрын
They are mainly Matthew Walker knots, but there is a Turks Head there so you can make a slight adjustment to the cord length. Does it make a difference? I'm not good enough with them to really comment, but it seemed like an interesting thing to try. If your ammo is heavy enough I don't see why you might want a heavy pouch? Personal preference is everything and what others like/don't like is up to them - and if you don't try - you won't know! So keep experimenting! I did try a single loose loop on a single strand sling. It worked, but I wasn't a fan. I haven't tried all the options yet, so I guess the answer is to try it and see. If you make the loop big enough and don't like it loose, put a Turks Head on and tighten it up. If you don't like that, slide the Turks Head of the end and convert it back to a double finger loop! (Or leave the Turks head to aid in tightening the finger loops)! Matthew Walker knots - I did comment that I found they tended to 'walk' so you really need to be careful with these. Have you watched my other video about 'whipped' slings? Worth a look - let me know how you get on if you try it! I think you are right - more strands = greater stiffness, so less whip effect. Those crackers may not work! I built a 4" pouch for golf balls. Not too good for tennis balls - stick with 6". I also had a fair size stone 'stick' in the smaller pouch (gripped by the cord during the swing, presumably the cords stretched and contracted on release) another reason to go bigger and stay with 6". Round braid - looks pretty! Cracker - I suggest you consider making it at least 6" long. Mine 'crack' but not very loudly, so longer may be better! I have another sling video out soon, so keep an eye out for that one. Thank you for your interest and taking the time to comment.

Rather than using the Turk's head on this one, still going to try it (hope you're fine with me asking for advice if I don't get it right), used the double loop I've used on the others, from blind squirrel, but just doubled it up to a single and singde it up the same way; it seems easier to throw for me personally having more of the fingers free.

I just bought a BMS I thought might be suitable from AliExpress and have made some inroads into getting it fitted. I just need time - life gets in the way. It will probably work at charging the batteries. It may not work when on the vacuum because two of the inner connectors on the battery pack are marked rx and tx. This implies some comms from the battery to whatever it might be plugged into. There are a couple of LEDs on the charger unit that indicate battery state (i.e. good bad etc.). It would be great to think that the charger did some form of battery analysis - but that would be economically stupid. I suspect the original BMS is sending some form of signal out that something cheap and cheerful in the charger interprets and operates the LEDs accordingly. If I was Vax, I'd use that same system to signal to the device the battery is plugged into, what the state of the battery is. I strongly suspect that because this substitute BMS won't do that, the device I'm trying to power (a hand held vacuum cleaner in my case) is going to just refuse to work - because it isn't getting the required signal. This is just a guess from a world weary and cynical engineer though! I'll try and get something done this weekend!

You could do it with this project if you wanted, but it wouldn't be particularly efficient. You'd need to boost the voltage from the USB from 5V to about 9 or 10V, then you'd need to feed that to a 1P2S BMS board. I considered it, but binned the idea. You could fit the circuitry in the 'spare' space in the belly plate. If you used a USB C with a 'spoof' circuit to fool the charger into supplying a higher voltage, that would probably be more effective. As I said in the video - it probably isn't a good idea to charge a LiPo in situ in the toy - especially if you weren't also going to do any temperature monitoring. I have seen a Roboraptor with an arduino mod to improve the walking algorithm. Making one that could jump, with realistic skin and autonomous action.....might be a few years before we see one of those! Thanks for commenting.

@@ECEtek I have heard tail the LiPo batteries have habits of Spontaneous Combustion. specially when it comes to overcharging and of course temperature. however i have a Alpha Training Blue(robot Velociraptor) which does use a LiPo battery 6.6v only difference there is that it uses a 3 pin connector/specialized charger which has a light when its charged only takes about 30mins per charge sometimes less with about a 2 to 4 hour life span give or take. though i have no experience in robotics or electrical. however its been a massive interest. i would say that the Jumping and Autonomous action would be possible looking at Atlas from Boston Dynamics. the skin has been done before the problem would be touch sensors and making it last as Latex does not last long. they exist but yes putting them together with technology that would have to be invented for the project would take decades. the biggest problem is making them ultra realistic. Synthetic Pneumatic muscle, Liquid joints. and using hard plastic, Silicon, and perhaps. faux leather something. Liquid Cooling. etc. to make the thing feel less robotic and more organic. a Synthetic Organism. leaning more into science fiction at this point. kind of push the boundaries of what would count as a toy. more companion than toy. think robot as intelligent as a dog. than input output like roboraptor.

Can i use 5v voltage adapter
@ECEtek9 ай бұрын
What do you want to use it for? The regulators on this board are low voltage dropout regulators, so this means that they need the supply voltage to be slightly higher than the voltage you want out from them. The extra voltage is used to make the regulators work and any surplus is dissipated as heat. If you want to supply the whole board with 5V this probably isn't going to work because: 1. The 5V regulator supply voltage will not be high enough. 2. The 3V3 regulator is supplied by the 5V regulator - and if this isn't working because the supply voltage is too low, then the 3V3 regulator won't have a supply voltage and won't work either. BUT You can still run this board from 5V if you are prepared to do a bit of fiddling. You can either wire your 5V power supply onto the output of the 5V regulator - This will put 5V on the output pins and so you'll have the 5V from the supply to power your 5V applications and the 3V3 regulator will also receive a supply and so will out put 3V3 for your 3.3Volt applications. The easiest way to do this is either by powering in via the USB OR wiring the 5V supply on to the board via the 5V and Ground pins. It is a bit Heath Robinson and I probably wouldn't advise this for longer term use! It would be a lot easier to use a 7V, 9V or 12V supply - although the higher the voltage of the input the hotter the regulators will run (as @robc8468 correctly points out above). Hot regulators will degrade faster. Just be aware that if you follow the 5V route I mention above that some PSUs have a very rough and ready output with a fair bit of tolerance for output voltage with load and they can also be pretty noisy. This may mess up whatever you are powering. The input and output capacitors on the regulators usually deal with anything coming via the regulators. I hope that helps.

Using the 3 volt regulatior directly on the 6-12 volt would generate a lot of heat and wasted power So knocking the voltage input to 5 volts first before sending it to the 3 volt regulator makes a lot of sense to me.
@ECEtek Жыл бұрын
A fair comment. I normally use a 7V supply on these to limit those losses and the heat stresses (although when I blew this one I was using an adjustable supply - clearly not the best idea!). This arrangement does limit the current you can draw from both regulators though, as the output of the 5V regulator is going into the 3.3V, so whatever the 3.3V regulator is supplying, plus losses through the 1.7V voltage drop need to be subtracted from the 5V potential output of 1A. I agree with you though and for anything remotely power hungry it would be far better to use a Buck regulator circuit (or two!). I really appreciate your input and interest, so thanks for commenting.

That is a tad odd as I'm reasonably sure the pins on the outer ends (that would go into your breadboard) are just fed straight off the regulators via their respective jumper. Have you got the jumpers correctly placed? If your jumpers are in the correct place then I'd try disconnecting power from the MB102 and tracing the tracks for continuity. Rather than trying to contact a track just check at the pins. Have you got continuity between all the 0v pins? Have you got continuity between the 5V pins (including the USB output). You can also input on the USB port if you were of a mind to. All pins of a specific voltage should be common to each other.

Sonoff = v poor reliability, had 5 which have all failed now, wont connect to WiFi. interesting video on the fault-finding /repair. Which other make is a better option I wonder
@ECEtek2 жыл бұрын
Thanks for watching the video and commenting. I usually flash all my Sonoffs with Tasmota and never had a problem with them thereafter. I have an S26 plug/socket, factory fresh with native Sonoff software that will NOT connect to any wifi. I'll flash it with Tasmota and let you know how it gets on. I've put Tasmota on many ESP 8266 devices, including ESP01, ESP07 etc and it works great. There are other firmware versions available that probably work well too. Might be worth giving it a go. With Tasmota I've not had much luck initially flashing OTA and always use a hard ware connection method for the initial flash.

Just a quick follow up on this one (I know it has been a while). The Sonoff S26 mentioned above I flashed with Tasmota, but it still wouldn't connect up to my network. I tried all sorts but couldn't get anywhere. It was visible and connectable using it's own WiFi but not visible on my network. I changed my router as a result of a new broadband package and up it popped no problems and worked as it should. Must have been a limitation in the older router.

hello brother I use the same board as yours. and i got a problem at the 5 volt power regulator and i am ordering the 5 volt power controller (ams1117 5.0v) from the online store I would like to ask if I can replace it and replace it with a new one. Will it solve the problem? Or do you have any good advice for me? I'm sorry, I'm not very good at your language. so i use google translate
@ECEtek2 жыл бұрын
You can replace the 5V regulator with the one you have identified. I replaced both the 3.3V and 5V on my board and that worked OK - but I also had a problem with the conductive track from the diode to the input pin of the regulator. Do some continuity checks and make sure the tracks are good. What caused your problem? Make sure you eliminate that first or you will burn out the new regulator. I would remove all the jumpers from the board until I knew that it was working - check the voltage at the regulators. It would be easy to short out the regulator with carelessly placed jumpers if you were not careful. :0) Google translate worked ok! ;0)

I have tried using a few of these. Had 2 of them burn out at the 5v regulator, it will output the same voltage as the input voltage. The recommended input voltage is writen as 7-12v. I am trying on the old repurposed power supply (between 7-12v), I am not sure if this is the cause of burning it out. Can you give me some advices to avoid damaged this regulators
@ECEtek2 жыл бұрын
It may be that you have a problem 'downstream' of the 5V regulator i.e. on the output of the regulator. These chips are rated at 1Amp max. If you have a short on your regulator output then that might cause a massive current demand that then burns out the regulator. Take the regulator chip off and then see if you have any shorts on the output circuit. If you do i.e. if the 3.3V regulator has an issue, then fix that before replacing the 5V regulator chip. Your power supply may also be an issue. 'Re-purposed' suggests a home made or home modified unit. It depends on what you've done/used. Old PC power supplies can be great if modified correctly (lots of KZbin videos on how to do that).Try powering the board from something with a known voltage e.g. a 12v car battery or even a 9v battery like a PP3 or something. At least then you know your supply voltage is relatively stable. Then check your output voltage and make sure it is being regulated as you expect. Hope that helps.

@ECEtek3 жыл бұрын
Is it the same model of relay board? Some pins have to be in a particular state for the ESP01 to start up correctly and you may have an relay pin connected to one of those. There is a useful instructable here that may be of value to you. www.instructables.com/Definitive-Guide-to-Setting-Up-Your-New-ESP01-Modu/

I haven't experienced this issue with any of my relay units that I can remember. It seems to be linked to the need to set particular pins in particular ways at certain times i.e. at boot up. I suspect you are having the same issue as is being discussed on the ESP8266 community forum. They have a solution there that may be of value to you. Have a look at this and hopefully it will help you. It will need a bit of a 'fudge' with your circuit though. The community forum is filled with lots of people with a wide range of knowledge and perhaps someone else may be able to help you further. I do hope this is of value: www.esp8266.com/viewtopic.php?p=75082 I also found this thread which confirms the initial spike is related to start up mode of the ESP01. www.edaboard.com/threads/why-on-startup-led1-connceted-at-gpio-0-once-g

What's the app and where to download?
@ECEtek3 жыл бұрын
There is no native app for this device. It is designed so that it hosts an esp8266 chip on an ESP01 board (the little black board in the picture). You can flash that with Tasmota which will respond to your Echo devices in an emulated mode, or you could use TasmoAdmin, or you can enable MQTT and use applications such as Node Red etc. to control it. There are other programs like ESPHome that you can use too. Thanks for your interest.

Nice investigation! Worth mentioning to be very gentle with removing the daughter board. I lifted pads before due to overheating it's a mess to fix after :)
@ECEtek3 жыл бұрын
Thanks. A good point about the daughter board. I always used to use a desoldering pump, but it wasn't always the best at removing all the solder. I picked up a nice tip off Big Clive's channel and dip my soldering braid in flux before attempting to remove solder it works like a charm! Never liked braid before, now I use it all the time. It makes good contacts for Scalextric cars too!

I got that same exact stainless steel type as yours .. Which sight do you like to use more, the square or the round type ? i cant decide which sight to use.
@ECEtek3 жыл бұрын
I don't use the sights as I tried them but don't like them. I prefer guesstimation! If you are consistent with your setup (brands/taper/ammo/range) then they are probably really useful but I'm still playing with mine to see what I like. If I had to choose I'd go for the circular ones as they hide less of the target. Thanks for your interest.

If it is any consolation: it wasn't just you mate. Lots of negative observations on the earlier versions on various forums. Some fixes too. No issues with this one. Just be aware of the poor HV isolation as others have pointed out.
