    Interesting and useful facts:
    1) If you only purchase 5 boards (instead of 10), the shipping cost is lower.
    2) If you use "Panel by EasyEDA", you can fit more boards in one panel (2x5 panel in this case)
    This results in 100 boards (2x5x10) at the price of 2$ !!!

      @@JS7457 I think the price is fixed depending on max board size, e.g. 5x5 or 10x10 cm. If you actual board is much smaller, then it can be "duplicated" on the 5x5 or 10x10 cm "panel". In that case you would get more boards for the same price.

    A big thing that helped me building buck/boost converters is knowing the ideal values of the inductor without needing to reference the datasheet each time (especially with general purpose switch controllers that might not have the specifics for inductors). I found an equation online for estimating the required value of the coil in a buck/boost converter, I then plugged this equation into a spreadsheet so if I need to build anything all I need is the input voltage, output voltage, frequency, and max current. This helps save space on the board and money in your pocket rather than going straight for the largest reasonable value. Not a huge savings unless you make a lot of boards but it's still helpful for making good buck/boosts. The value in henrys is L=((vin-vout)*vout)/(vin*Imax*hz*0.35). Thanks again for yet another awesome video Great Scott!

    As someone who knows how painful it can be to design, layout, and manufacture PCBs, you made it look really easy! Their software looks very much like Altium only web-based, and a few thousand dollars less too!
    A few tips for soldering SMT components:
    Make sure your Gerber files do not have a solder paste layer if you intend to hand-solder the components rather than a pick and place machine. This will mean your boards are (mostly) flat and free of excess solder which makes it much easier. If there is extra solder from the solder paste or HASL finish, then use solder braid/wick to remove it.
    Soldering SMT capacitors and resistors, apply solder to the PCB on one of the pads of the component and keep the iron on that pad. Using steel needle nose tweezers, slide the component onto the solder pad. Remove the iron and let the solder joint cool. To make sure it is flat to the PCB, rest the tweezers on the top side of the component with very light force and briefly touch the iron to the pad. Then simply solder the other pad.
    ICs are pretty much the same. Apply solder to one pin on the PCB, slide the IC into place with tweezers making sure the other pins line up correctly, remove the iron and let the joint cool. Make sure it is flat against the PCB, then solder the other pins starting with the pin most opposite.
    I find this method more reliable and produces less thermal stress than heat reflow with a hot air gun.
    If you are going to heat reflow after soldering for presentation, try using flux jelly in a syringe from the usual suppliers. It helps for faster reflow and a nice shiny finish. Makes soldering a lot easier for me!
    Hope this helps! Keep up the great work with the entertaining and informative vids :)

      His SMD soldering ain't that good at all. Try to hold a resistor/capacitor with tweezers in place and then solder one end of it - and you can easily solder another one after that. Same with ICs in QFP, SOT23 and other packages with leads - solder one of them by holding IC in place with tweezers - and you can finish other ones easily. Watching resistor flipping up during soldering in this video is a pain.

    I just ordered a batch of boards and parts!
    Looking at the layout, I noticed the ground/thermal pad on the TP4056. This would be tough to connect with plain hand soldering (I also noticed in the how-to-solder video you just attached the leads of this chip and seemed not to solder the pad underneth)
    If i run in to heat issues with the TP4056 I might make another batch of boards with some vias on that pad and a larger copper region added on the back layer as a heatsink. I saw in some other tuturials (Including one by Dave /EEVblog) that you can use this technique to solder the pad from the underside, wicking solder through the vias with the help of some flux gel.
    Never made PCBs or used Easyeda but in 20 minutes or so I was able to cobble together the changes I mentioned above. This is fun!

      Yes. If you order your parts through LCSC, then they even ship them with the PCBs and you can save shipping costs. It is really convenient.

    Very educational! If advertisement was always done this way I wouldn't mind it. I just created an account there and will be ordering my next PCB from there. Very convenient! Thank you!

    Can this be used on 18650 cells too?

    • @greatscottlab
      @greatscottlab  7 лет назад +16

      +HellFireno88 Yes

    • @HellFireno88
      @HellFireno88 7 лет назад

      I know. But saying 18650 is a quick way to say li-ion 3.7v cells.

    • @GGigabiteM
      @GGigabiteM 7 лет назад

      NiMh batteries should not be charged with a LiPo battery charger as the method of charging is different.

    • @GGigabiteM
      @GGigabiteM 7 лет назад +1

      It's probably worth a look into NiMH batteries because a good NiMH battery can come very close to a lower capacity LiPo in power density. For what you lose in capacity you gain in safety, as NiMH batteries don't have violent failure modes like LiPo batteries do. They can vent and leak, but they won't explode or catch fire.
      The reason a LiPo charger won't work on a NiMH is because as a NiMH battery is charged to near maximum capacity, its voltage will drop slightly, which can confuse a LiPo charger into thinking the battery needs more current.

    • @GGigabiteM
      @GGigabiteM 7 лет назад

      I do the same with old battery packs to get 18650 cells (and occasionally some weird flat cells), but I'm too lazy to match the capacities of the used cells and usually just end up using them individually or in pairs. Some crap battery packs use crap batteries from the start, or have really bad balancing which ruins the cells.
      I have a pile of dubious 18650s which have nearly no capacity from some of the cheap Chinese battery packs. About the only thing they're good for is using in single cell battery banks with one of those LED USB flashlight things.

    @MCsCreations 7 лет назад +2

    One problem I've been facing with TP4056 with protection board - and that is present in your circuit as well - is the 1A limitation. It's great for smaller projects, but for projects where you need more current it let you down. Power banks, for stance, smartphones demand up to 2a. So what I end up using is the unprotected board in conjunction with a small BMS (the model depends on what I need). So, it would be a good idea to create one unprotected as well, for your future projects. ;)

    Hi GreatScott, can you explain what the problem was with the first version of the board? In my last video I made a mini boost converter by putting an MT3608 on an SMD adapter board (see ruclips.net/video/K7Lv5FWTX9Y/видео.html ). The output current I measured seemed to be quite limited and in my case the capacitors are too small. I also think the small 22uH coil I use is too light for higher loads. Thank you for making your videos. They help me a lot to understand things! +1

  • @Music_Engineering

    Aren't Li-Po batteries damaged if their voltage decreases below 3.2 V, meaning that your over discharge protection circuit isn't harch enough? :)

    • @chrisakaschulbus4903
      @chrisakaschulbus4903 6 лет назад

      as far as i know if you don't drain it too long the battery will recover a little... but the opinions, like everywhere, go from "never discharge it below 3,7" to "i discharged the battery to 0 volts and i can still recharge it without problems"... what i've learned is: since it's a bag full of chemicals, you can only test what works best for you and what you are comfortable with

    • @0x8badf00d
      @0x8badf00d 6 лет назад

      Bigclive has a video on it. If you discharge it to 0 V, it'll still work but it won't be as happy anymore. You'd have to reverse charge it to a negative voltage before it shorts internally.
      When you have cells in series, you need to be careful. That's when cells can be reverse charged and cause mayhem when the pack is recharged.

  • @ABaumstumpf
    @ABaumstumpf 7 лет назад

    Not too long ago i helped a friend designing a circuit board. 2.4x2.3 cm, ~30 connection-pads to diferent boards, 2 connectors, voltage regulator, 9axis sensor, infrared sensor, molex connector - and a freaking 40 pin chip.
    took us 2 days to get all the traces on the tiny board.
    When we finally managed to squeeze in all the connections we enlarged the power-traces. The datatraces were 0.154 mm, power was 1.5 mm :P better overkill than sorry.
    And darn - all those wires.... we had to skip layers so often to fit in all the traces that we had something like 150 holes on that little board.

    I wish I could do things like this. I am trying to reach my self or learn as much as I can. I'm a little old for school. but I use Google and RUclips. my goals are to build a inverter to power my off grid home. and some big DC motor controllers. and a battery charger for a electric vehicle conversion. some reason I don't like to buy anything. I want to make it myself . someday I may reach my goal. it may not be how I want to. but maybe I will get the projects done. but there is a lot of other things that I'd like to build. I have learned a lot in the last year and 9 months. that's when I really got into electronics. the DC motor controller is what got me started. I have worked in electrical for years. home and auto. so I have a little knowledge to start. your video's are a great help. you explain things well. and at a pace I can keep up with. I haven't gotten in to the smd things yet. still tinkering with through hole devices . but hope to improve my work station. and buy better tools. a good temp controlled solder iron. and supply's. maybe try etching PCBs. great video as usual. thanks ...

  • @pault6533
    @pault6533 2 месяца назад

    The TP4056 has a solder pad on the bottom side to reject resistive heat. As a good thermal management practice, there should be multiple PTH connected to the bottom layer and a large continuous plane on the bottom layer to act as a radiation plate. Also, if the W*h of the lithium cell used is less than 4 NiMH cells, there is nothing to gain in run time, only lower weight and convenience, if appropriate.
