Actually I rather meant the indicator setup you designed
The dect stuff. It's very cool butt rather niche as you say
Oh! I did wonder.
Well here's goes the indicator lights story..
I bought a set off eBay (an integrated brake light and two amber indicators, with a wired handlebar switch, and it runs off ultrabright LED's and 3xAA).
At < 5 quid I wasn't expecting much. And like many things from China, it was shockingly bad, not only were the lights very dim and unsuitable for indicator lights in daylight, but the whole thing fell apart.
HOWEVER, the housing matched and fit the end of my eMezzo rack perfectly and it looks great. So I thought, why not strip the insides out, source some 12v LED's use a voltage stepper and a 555 timer chip (even the indicator lights flashed too quick on the original circuit).
So basically that's what I'm building! I have everything now. I got some mega bright 12v LED's but I'm still not convinced they will be bright enough in daylight. We'll see. I may have to build some better reflective background.
As soon as I get time I will happily share my project and post pics and videos along the way.. In fact, I might do some now of the device before I strip it out, like a 'before and after'
The other thing is.. I don't like the idea of adding more wire over the bike/switches on the handlebar. I was thinking of perhaps doing a Bluetooth option and making a simple app (I have a Bluetooth wrist watch and also a holder for mounting a smart phone on the bike itself). Bluetooth might not be safe though/reliable enough and would require a lot of testing.
But surely, anything is better than sticking your arm out on an electric bike! It's not ideal or very safe really is it, when moving under power? Especially if using a throttle!
I'd welcome any other ideas on different approaches re automating or making the indicator lights wireless? The brake light is actually wireless (to an extent) it uses a crappy little switch which is near the device and intended to be attached to the rear brake lever at back of the bike, when you squeeze the brake it closes and the big red light in the middle comes on. The lights are intended to be mounted on the seat post I think.
Picture of the device..
At the bottom is a breadboard with a 555 timer chip on it, and just above that two of the 12v
LED's I sourced from China (notice how they're flat with FOUR LEDs on each panel. I powered
one up from a 12v DC battery I have, they're very bright indeed and very cheap, only about a quid for a pack of 4 I think.
At the very top is the rear brake light switch, and the handlebar switch is at the bottom which is 3-way for indicators, and an electronic horn that is also built into the device (actually plays 7 silly melodies so clearly this is more of a toy, aimed at the kiddie market than a serious indicator light).
Upper right is my little key-ring camera. I thought perhaps this (or something like the wireless fob switches used to open garage doors) could be used to turn the indicator lights on/off using radio frequency.
