nice project but why to complicate with arduino?you could totally hack the servo and use just its motor with gear reduction, one switch to change directions and one to turn it on/off and wire external potentiometer to step down conwerter to change its speed

you could make fully encapsulated body to prevent dirt and other parts to stock on magnets

nice idea!I was thinking about to make a ring with magnets to make frictionless dinamo on my bike but there was always a problem with complexitythis use of eddy current is genius for such small load as LED lightsyou can also add little voltage regulator, bridge rectifier and supercapacitor so it can stay light up for several minutes after you stopped or slowed down(I had the same circuit on my classic dynamo and it was working great until I bought new bycicle which unfortunatelly didn't had one)

nice projectcan you upload some videos with it in action?

these LEDs are more power hungry so they will glow shorter time but it will look nice anyway :)

maybie breathilg LED effect in spider chest would look more cool

if you can remove the voltage regulator you can power it directly by 3V without power losesthen it can run efficiently on button cells

nice thank you for sharing

thanks

helloI using this 2mL tubes for SMD components and 30ml tubes for clasics resistors

code is not mine so I don't want to use it without permition

I used them only with my phone but they are common NFC chips they should work(i used Ntag215 and Ntag216)

HiI recommend to use NFC stickers they are cheap and really thin and is verry easy to hide themyou can find them on eBay 10PCS just for $1.50 (just search for NFC sticker or label)

hello i didn´t read whole instructables just intro but i didn´t saw which type of motors you usingthis guy have good working solution: he using cheap geared motors and sollar pannels from ebay it looks like idea what you was describing

thanks

10 boards from PCBway or JLCPCB cost under $10 including shipingand other componnents are pretty cheapcharging modules 10pcs around $4 (you need three)step up around $1I used 3x panaconic NCR18650B they cost around $3.50 their capacity is 3400mAhbox $1.50connectors 10pcs around $2so whole basics box is around $15+ lights ($2/piece)and solar panels 20W around $30I bought 10pcs flexibile panels for $85 (they cost $5.5 each but shipping was expensive)

Hihow accurate are final measurements ?do you have something to compare measured valuesalso i want to know what you have on display when you measuring all batteries and if is you can measure only one battery

nice idea but you should add schematic for USB (not everyone knows how to connect it)

nice technique for PCB making

i know where to find gerbers but onhers notwithout any informations where to get PCBs looks this instructable litle bit pointless for me if you have links to all componnents needed except main partdid you try to contact owner and ask him if you can add links to his page with gerbers ?

hi nice instructable bud why you didn't add gerberfiles for that PCB if it is opensource ?

do someone experience massive lag when open this instructable in chrome ?

this would be real think it is called hololens from microsoftbut nice instructable firs DIY version what i saw

many thankslightening that bunker was my favorite part of this project :)

thank you

actually it's not that risky if you have a powerful soldering iron, low melting point solder wire battery will be ok

nice idea

i had same problem :Dthis instructable help a lot :)
