OK rhe white stuff around the capacitors n other components is only being a rubber caulking so to hold the components being that if dropped it now will not break as it has in the past on such things declared as dumpy today lol. If you cover a board completely u can even throw it like a football and play catch with it. That's a joke but not about the caulking, it's only that alone and nothing more. Great video by t he way
i have installed it in mu ubuntu 18.04 but cant find how to open it, please help, where can i find this open sankore after intalling it on ubuntu 18.04
Why you are demonstrating the items that you used. Should simply show how the batteries should be connected using the items easily could be available to every one.
Thanks Pal. DIY MEANS YOU DIY. thanks, that you didn't say: "Just buy a "'MODULE' [for how to make things....] (In lieu of the REAL NON STUPID PEOPLE.....[that don't say: "If you want to make a charge just buy a module" ETC...and THE GITA MOVEMENT :O). Appreciation
Yeah that is glue and it's on there to absorb vibrations so the board operates quietly when the inductor coil is humming at 60hz and the speakers are shaking the board.
WTF, I can't for the life of me figure out how I'm supposed to share my whiteboard with another user in Open-Sankore. This being the definition of the phrase "virtual whiteboard" I am very confused. If it really is just a single user application, it is not a "virtual whiteboard" it's a sketchpad. As it is, this thing seems entirely useless and redundant as I might as well just use Corel Draw or Inkscape.
For the white board, I used Open-sankore, but openboard is identical which you can download here github.com/OpenBoard-org/OpenBoard/releases/tag/v1.3.5 The recording software was RecordMyDesktop which is in the Ubuntu repository (software center). Editing was done with KDenlive available for Linux and windows. Transcoding, I used handbrake.
Wait a few second for the caps lol. Short the caps out with a 5 W resistor. Replace all the caps on the power supply with high rated ones. This guy has no idea about connectors. He is no tech. But I enjoy it.
Nice battery pack and a simpler construction that many others. I had a similar idea but with spring plates top and bottom to make connections a little more reliable and easier between different batteries. It seems like those China eBay sellers could sell spring loaded DIY kits that would be perfect for the average home DIYer.
I wish that uyou had touched on the spring portion of the design, like where you got them, and where you got the strip solder that you used. Also, where did you obtain that flat copper stock that you used. This is a great design, I would love some links to the items that you used.
dunno if you guys gives a damn but if you're bored like me during the covid times you can watch all the latest movies on InstaFlixxer. Been binge watching with my girlfriend for the last months =)
Love this video. He is the only guy who planned and executed an original design with spring loaded pack. Only pack I have seen, where you can pull out one battery at a time. My only concern is, over time, oxidization of the connection. I wonder if you could gold plate the terminals so there is always a good connection.
Thanks! I was thinking about gold plating them before, or using some parts recycled from old PCs that are gold plated already. My next pack is definitely going to have some improvements, even though I did not run into any problems.
Hi David, Aqua regina can dissolve gold from your PC boards, but is highly explosive. Dangerous around organic solvents. Years ago, you could buy gold plating solutions which were not too expensive, but the price of gold in the 80's was low. Typically, companies here would gold plate a small circuit board for $2.50 US. Tesla, appears to be using tin, or tin plated metal and punched out the battery design with a space for their @6 amp fuse, I wonder if its possible to send the design to a pc circuit design company to make 2 prototypes for testing. I seen video where these 6 amp fuses were hand soldered ( hundreds ). Seems, too flak tome. A copper bus bar would be needed to carry all the current. I do not like the idea of a BMS, I know nothing about charging $1,000 US in batteries. I like your design because you can remove 1 cell at a time to make sure it is properly charged.
well done buddy have you thought of getting this pack in production and put on sale. You Have been very thoughtful all through the build, I was totally engroused and enjoyed every bit of it - ALAN. Sheffield, England, UK
Hi David, I love your design so much that I'm going to copy it, but with a twist. I'm going to avoid BMS and balance charging by using interchangeable 18650 batteries. The batteries will be charged individually then placed in the box. When my ebike (a Sondors Thin 36v) tells me the batteries need charging I will replace them with other pre-charged 18650's. By using this second batch of 'ready' batteries I should be able to make the changeover in less than five minutes and this should give me a range of over 100 miles or 160 KM. My batteries are all reclaimed from laptop batteries. All of the cells I use will be over 2KmAh, most in the 2600 to 2300 range. When I get the box built and installed I will upload the finished product. For now you can see my first attempts on my channel. Many thanks for a great idea.
Hi. Thanks for the video. If you take the screen apart like this, do you risk increasing the chance of the screen undergoing EMI interference and such? Does the wood and the tape insulate such interference?
I did not notice any Electromagnetic Interference (EMI) at all. Wood,when dry is a very good electric insulator, though it should not protect from EMIs nor cause them.
Lots of magnetic fields are happening but none are being an interference nor will any magnetic power ever be one in electronics in this way being it's a separate signal let alone a completely different type of signal. If it was a hz and u were adding another board with a crystal oscaltor/Bluetooth component then a interference is 100% gonna be especially if not in sync yet.
Hi can you tell me how many lithium batteries I would need if I was drawing 12v 300 Watts for two and a half hours . Excellent video by the way thanks Jason
Nice pack design wonder the cost of these pexiglass design battery holder. He is in Germany, so there is many companies doing this work. Canada has few such companies.
Great ingenuity , BUT I see a serious concern....there should be fused protection for each cell, like you see in the tesla s, or most all electric vehicles, if just a single cell shorts and doesnt separate itself from the pack you just created a hell of a fire bomb...... the thermal runaway would be insane
Nah, it's a flicker of the backlight - you see it clearer the second time round - it's just because the caps are gone, and the backlight can't start... it uses the caps to kickstart....
