Hello, congrats for your design, and thank you very mush for sharing it !It looks really interesting, at last to have a good working and efficient solar charger.I don't know so much of battery and electricity, so I have a few questions about your device.First I see few feedbacks,in spite of the deep relevance of the MPPT design. Do you have some new observation, did you fix the issue raised by Marbo ?Does the charger work well for you ?I'd like to use a charger for AGM or "deep discharge"-able battery, will it work properly with this kind of battery ?

Hello, that sounds like a really nice project !(may be too complex for a lot people however,mixing it with the design of an arduino from scratch may not help, it does not help me at least).I am not so good at coding, but really interested in both monitoring and telling which kind of battery is being used. I did not understand my glance at your program, put in words rather that in code, how do you test check if a battery is of one kind or another ?And anbother question, does your sensor work if the battery has just been used or charged a bit ? Do you have any accurate tension measure in spite of that ?I ask because I just realize as for car batteries, ie Acid lead starter batteries, the tension is decreasing a lot in the minutes and even hours following the charge. My goal is to make a ...

Do you have any accurate tension measure in spite of that ?I ask because I just realize as for car batteries, ie Acid lead starter batteries, the tension is decreasing a lot in the minutes and even hours following the charge. My goal is to make a "coupleur-séparateur" no idea as for translation in English, the idea is a device that puts both a van starter battery and a living-off-the-grid-in-a-van battery in parralel just when the motor battery is full or almost, in order to recharge the other battery, and cuts their link when the car alternator is off. (With a relay under ATtiny or arduino control)I want to monitor the achievement of charge of the accessory battery, to prevent it from overcharging. But i don'tknow how to ensure the measure is accurate while it is being charged.Any help in that scope would be very helpful.And congrats once again.

It's been a while I "favorited" your foldable bike, and I am still planning to do the same some day. The idea is really nice. The only other solution I found is thescaffold angle attach system(https://www.instructables.com/id/Folding-Fixie-without-welding/), which looks fine too.Just a suggestion, don't you thin about grinding the corners of your hinge ? They are useless for the solidity of your bike, make more weight, and you could cut them out in a smoothie / round way so that hitting your hinge would hurt less.

Did you not have to change the position of your rear brakes to fit the new wheel size ? In this case, how did you do ?

Thanks for your advices !

don't use tabs and pills unless the doc asks you. carry no cream, just a tiny soap and few shampoo. Why the hell so many stuffs ? do you nerd them ?

Excellent ! Beau travail, pour une noble cause !
