  1. So i finally decided enough is enough. the charger is done. thanks to all the people for the input and the persons that wanted to take the plunge on the first 2 that made it possible to start. Dont mind the pictures... i once more dont have a complete version myself to make new pictures.... ill update them when i finish one. but enough of me rambling here the specs and such. NP50 Charger V3.0 (own circuits with converter) Features/specs Smallest form factor of all NP50 chargers on the market. (HxWxL) 4.92 x 11.4 x 6.4 cm. Charges 8
  2. Hi might be a weird question. but i dont want tot waste materials ! so this was one of my prototypes and i made 2 of them. differences is clamping force (compared to the new one) and logo. i tried to find a balance of clamping force and easy of getting a battery out, they wont let go out of the blue. but still. They are in perfectly working order. maybe someone is interested in these for a mark off ? i dont want to waste the materials. electronics are the same as the final product. this one is just even a tad smaller. just let me know, ill keep them around. Kind regar
  3. Well thank you ! might not be skill but more persistence thing there are 4 in the bin, with spring contacts that did not worked out (cheap chinese ones...it showed) Well thank god its not alumnium since i would have troubles to haha
  4. I made my first test jig. since i made these PCB's and the tolerances of the charge chips, ar a bit bigger then i want i want to test them all before i use them. its a jig that has spring loaded pins that connect to all the points on the board when fixed down in the jig. a nice method to connect everything in one simple test without soldering. nothing new this technique, but i never made one since this is my first PCB heres a video where i explain some stuff if you might be interested.
  5. hahah no if this was my work, would not buiy tghem to begin with but a nice set of DPA's Thonnman was even so nice to NOT refund they said we talked to our studio devision and they said your voice should sound less great they are made for ambient..... well little do they know
  6. T100 soldering iron. could even be fed from the cart ! i myself have a weller station. but i still want this one
  7. Small update !! i got my circuits in !,and well they work ! but i do need to replace some components. i did not expect it to be perfect from software to actually having it in your hand. so i do need to make replace a few components by hand (led brightness between green and red for instance) i got the correct values now after seeing it so. Well im working on the housing of the travel version V3 Np50 charger. i did change up the design. since previous one i posted actually had more components. and almost no one wants a 4 bay Pic 1 light guides line up test
  8. Well i thought i just rewire some Roland Roland WPM-10 Wear Pro to be used one a ZOOM, or antyhing with plugin power.... well so far so good but watch and listen what then happens... |
  9. Well thank you ! i ordered my boards a few weeks ago ! i think i got the basics nailed by now but who knows hahah i always want them in my hands to be realy sure. i might have missed the brightness of the LED's or the position .. since those are rather critical in my design. if i cant manage anymore failures i will definitely contact ! thanks in advance !! a 12 way would maybe be possible i rather not make to many of them to be honest, one reason is it is on the limit of the DC converter, as well as i dont think its a good idea to put all your eggs in one basket when on set. 2 times 8 o
  10. Hi Guys and Girls I mentioned my own circuits for a while now and i just ordered some pcb's for a 4/8 Bay Np50 charger, i designed myself, took me some time since although people are willing to help. usually it ends up doing it yourself everyone is busy So my question is this. Anyone would be interested in a 4 bay or an 8 bay Np50 charger ? My electronics are ordered due to 2 willing people to take the plunge, without me or them knowing when i can deliver it since it might take some iterations. im low on finance so this was the only way possible. (without
  11. Thanks for some info on the current drain of the SSM,i was looking for that , and it is not stated in teh manual but draining the np50 to 2.8.. is rather low. might not be a problem if without load it shoots up to 3v but 2.8 is not normal. in all my tests i always drained down to 3v. about savings. its far more interesting not to charge the battery up to 4.2 with would be the max saturation charge. while charging up to 1.18 or so would hurt duration of use by minutes (like 10-15 or so) but will increase lifespan allot. by almost 100 chargers. i need to buy one of the lectros just for
  12. Well because my previous post, i've drawn a sketch, of what the charger might look like with my own made circuits. not much of a huge win in fabrication time. but because allot of people wanted something very space efficient. this is actually the only way to go, although be it much more work. there will be an adapter for powering the thing though. both leggs that hold the battery will show a light. one leg green for no battery or charge complete and one leg red charging. in this method you can see the difference also when ur color blind. Pic 1 shows the sizes in mm other pics w
  13. Hi everyone that is lurking in the dark, i hope you all had a nice vacation etc ? and i hope you did not all pre order a Soundguys Solution charger since i am so slow The 3 pin idea is really neat, i wished i came up with it (i wont use it of course) and i do wish them all the best!! Here a small update on my project Well i am testing aloooooot of charger currents and circuits, so far the replacement circuits, charges a little under the usual suspect chargers ~ 3% less. but then again i´ve measured some voltages of charged batteries on some... well other brands and they tend to ov
  14. well i amm still testing with some circuits that might replace the old ones... still thats not the way i wan to go. but at least if they work as i intended i can get a hold of as many to be sure i can fix some (some peopleblow them up by using the wrong charger) i want to adress that to if i can but cant acount for all of well mistakes but i might be able to sell some depending on how many i can get and if they work well. still my own cicuit is what i want no more chinese dependency
  15. Well by the looks of it more and more people i have to admit i got some troubles with getting my electronics. i might have replacements but it takes some time to see how well they work. at the same time i want to make my own circuits. but for that to work i am seeking some help from third parties, this costs time and potential some money i dont have. so i did not not forget about the chargers. but it might take a bit more time then i and a few others would like. but i hope i can come up with something before everyone found something else.
