c) I got 4 of the D1 foam frame blocks. Not quite sure why.
Because as a commercial entity they will have to pay for disposal of unsold products? If they send 4 blocks to each D2 customer the can reduce (or remove) there stock and thus save on disposal costs.

making pins more robust would be a good idea. something in the shape of tabs of son dynohub perhaps? otherwise a nice little unit!

It does look neat. USB-C connector is an interesting innovation. I think I'll order one when stock is available.

Seems ok so far, will attach to bike, shame there wasn't an option to have a plugged power option as in the D1 so rather unplumb all the existing wiring for my D1 I've knocked up a plugged lead sacrifice of a capacitor unit I had unused f I'm my D1.

I've got some USB C leads arriving tomorrow, a C-A socket and a C-Micro B lead suspect I'll stick with the C-A as I can then easily replace the end cable if it breaks.

No idea where I'll mount it, suspect I'll silicon the usb port and hang from the aerobars with a couple of cable ties when I'm happy with it.

Hmmm that didn't last long...   anyone else using theirs yet, can you confirm if there is supposed to be an LED on or not when it is working, mine worked and now doesnt work.  Cables all 'bell out ok' so pretty sure it's the D2.  Glad I didn't take the D1 off the bike whilst I was trying this!

Working - steady LED
Working, no or small USB power consumption - steady with off-blip
Initialise/warm up - flashing
Disabled due to dynamo lights - brief flash, then unlit

The manual also says
Quote
When the bicycle begins to move the Igaro D2 assesses whether dynamo lights are connected. For this reason it is important to only turn your dynamo lights on when at a stop as doing otherwise could result in dim dynamo lights
Could be irritating with a sensomatic light, having to stop to get proper lights at dusk, or when entering a tunnel.

The newer B&M lights just use the sensor to switch between daytime visibility and illumination mode.  I think they're following some DRL regulation or guideline or something?  I preferred the old senso behaviour.

Ta - I've been in touch with Andrew and I'm shipping my D2 back to him to investigate.

Hi All,

We had a few issues with the pre-release units (jiberjaber got caught with one of them) and they've now all been replaced.

As production has stabilised we can offer a 12% discount for anyone willing to write a review here on yacf. As before, write anything you want  :thumbsup:. The code is YACF201910 and can be used on our website for at least a month from now. Apologies we can't offer a larger discount but the electronics in the D2 are far more costly than the D1 and ultimately limits it.

Someone asked about the power pins. This was a trade-off, as there's NO room at all (to put it into perspective the D2 has the most condensed circuitry of any product of this genre including two stacked PCB's and three types of capacitors in the tiny casing). The only option was a wire coming out or the two pins. With the D1 we found users would accidentally forget to leave cable flex for handlebar rotation and rip the wires out so the pins avoid that. Although they're small we've used the best quality ones we could find, purchased here in the UK.

The production units (not pre-release which have all been replaced) reverses the decision to switch off with lights. Success will vary (speed, light wattage etc) but the unit will attempt to power share.

Also waiting on my D2 MII after it turned to ice cream in my top tube bag. Hope springs eternal and all is well with this next one.

Very interested in replacing my D1 with this unit especially now the no power while lights are on has been removed (i use power on at night to dip my bright light briefly for traffic)

igarocom: I am concerned about the USB-C connectors, I was following the development of your products on Facebook closely and at one point you publicly stated that you had modified some circuit boards as you found that USB-C tracks over with moisture far too easily. As you have made this unit very small I feel you have now used this more vulnerable connector regardless due to size constraints.
I understand the D2 does not require any air flow for cooling so i guess these are designed/recommended for internal storage now.

There's no such thing as a waterproof USB port. The smaller and closer the positive & ground track the greater electrolysis will occur when a bridging liquid (i.e water) is present. For this reason, as you say, USB-C is more likely to corrode when powered and wet. The simple answer, which applies for all USB ports, is not to get them wet when they are supplying power. This is why stem cap solutions don't work in the real world. USB-C was chosen for it's size, although the pins are more reliable than USB-A in terms of insertion count.

The D2 produces no heat so placing inside a bag is fine.

Really liking the look of the D2 (and would probably buy one if I didn't have a perfectly functional e-Werk), though I'm not sure about the power pins:

Given that it's going inside luggage because the USB port isn't waterproof, why optimise the form-factor and power input for handlebar-mounting?  Seems like the power pins are going to be vulnerable if it's rattling around in a bag, potentially with the cable disconnected, and a slightly larger case with a female power connector would be better.  (Or alternatively, given that it's going on the handlebars, why use a USB connector rather than some more 0.1" headers for the output?)

I'm not sure how I'd optimise this, other than with two different products.  Fair point about captive cables getting damaged; I don't like them either.
Careful, Kim. Your sarcasm's showing...

It is a fair comment, true and valid, but design has to have a commercial aspect. A popular design chosen by several of our competitors is the top cap design and some of these competitors are touting the design as waterproof. This is plainly ridiculous as with a USB inserted not only will water enter when power is on but it will sit in the connector and electrolysis between the pins will occur. However it looks small, neat and unobtrusive - so increases commercial success. More sales, a one year warranty and a higher initial cost mitigates failures. We're giving a 5 year warranty which is 3 years more than the next competitor - just look after the pins and USB port. (if you feel you can't, take out insurance!).

Yet again, this device has failed. This is the second D2 I have had. Further upthread, the first one melted in my top tube bag. I have written a 'not fit for purpose' letter to Igaro, giving them the opportunity to amicably resolve the situation. I won't disclose exact details yet on here, as I wish to give Igaro a chance to fix this disappointing issue.

I saw darren franks on instagram use a 'sacrificial' USB adapter which he silicon'd in-place creating a watertight seal. Obviously not really ideal...

I have to be honest as an aspiring dynamo owner I'm minded to just get a light with a USB output and call it a day.

Yup. My tourer has a B&M light with USB option. It works seamlessly. I'm pretty fed up TBH. With Igaro, I also think those tiny little prongs and the fact the customer needs to make adaptations themselves with silicone and waterproof bags etc just seems like you are buying a half completed product.

There are 105 components inside a D2 Pro, but with increased complexity increases the risk of later discovering a component that varies too far from manufacturer specification. It only takes one to cascade into a critical fault. We replaced one component around September last year (when all orders were replaced) and failures settled, but a second component was identified as potentially having too much variance under edge conditions around December and your unit has suffered from it. It is regrettable and annoying but understandable from an electrical point of view.

Our warranty procedure is first-class - it's rare that a company will offer to replace a failed product without requiring a return, not to mention potentially dispatching a replacement on the same day.

If you're choosing to silicon up the USB port that's because you've heeded our advice about USB ports in general. The D2 is identical to similar devices and dynamo lights in that if you get water in the port it will eventually fail. An alternative for rain protection is https://www.thingiverse.com/thing:3965039

The two power prongs are a size limitation. We pointed out about looking after them (like the USB port) so they will last. To date (about 6 months of D2 sales) no power prongs have failed.

I've come to the conclusion that I don't really need dynamo charging.  After several years of (thorough a combination of injuries, poor fitness and other commitments) not really doing more than a few days of touring in a row, battery packs have got better and intermittent access to mains power have been more than sufficient for my needs.  I think my E-werk has come out to play about 3 times, though I've made more use of solar charging when loitering within tent.

I'm still a staunch believer in the advantages of dynamo powered lighting: It's fit and forget, and always ready when plans or conditions change.  Adding complexity to that is a bit of an own-goal.

(Which isn't to say there aren't situations where dynamo charging is still useful.  If you're doing epic off-grid expeditions, sure.  If you bought a GPS receiver with an inadequate internal battery, not so much.)

Yes if I'm honest I don't really foresee needing much in the way of dynamo charging. It's more a 'nice to have' than an 'urgent requirement' for me. And on the other plus side it often means you can power a lamp using a battery pack for a while if you want some visibility for fixing a flat or whatever.

I went through a period of USB charging on bike (2013-2018) but also came to the conclusion I didn’t need it. The GPS runs on AA and the phone I switch off apart when using. I have some lipstick battery packs totalling 6,000mAH I got in 2013 which is enough to top up phone should it run low. I will probably get a higher capacity battery pack when they stop working.

Is the new one repairable, usb and input port or cables. Just found out my original one is goosed, can't repair if a cable comes out of the main unit. My revolution usb unit has been faultless the usb socket is a high quality plated one, igaro is aluminium on the old units,  changed them with sockets out of old pc cards as the always felt loose. Going to buy another revolution usb charger for Julie's bike if i find out its not user repairable.
