I ordered 2 green and 2 yellow kits for delivery to United States. Was notified of shipment on mar 25th, items arrived today (apr 12th), so 14 days total, which is pretty good in my opinion.
So on to the review:
Product: 5 stars Build quality is great, circuit board is a bit thin but is fine for the purposes. All solder joints are good, no dead leds or cold joints even after flexing the board a bit. Drop test from 3 meters, still works fine; shit it out of a paintball gun with some wadding towards a wall 5 meters away, plugged it in, works fine. Before anyone thinks these are unrealistic tests, I plan on printing a back plate and diffuser for these and using them on backpacks for search and rescue + night hiking use.
Shipping: 5 stars Free shipping, arrived in 14 days from the time I was notified it shipped. Better than most of my aliexpress orders, so am definitely no complaining.
Documentation: 5 stars Absolutely no documentation. 5vdc model has a usb port, if you need documentation to figure out where to apply power... well... documentation probably won't help you, you have bigger issues.
Communication: 5 stars I was notified of shipping, it arrived, I ordered more. I am 90% sure if I had an issue, it would be resolved quickly, as ordering and notifications were handled quickly.
In conclusion: The leds are bright, timing on the movement is perfect, and these will work perfect for my needs. I went ahead and ordered 4 more in red (2x 5v, 2x variable voltage) for later use. Will probably install one as a third brake light in my jeep, and use the others for markers and such. Great product, great price, good shipping times. Dude makes a great product.
I've made two 3D-print mounts for this Larson scanner and uploaded them at Thingiverse. One with Molle mount and one for textile. You'll find the stl files here: https://www.thingiverse.com/thing:3399338
I made the mounts to use for visibility and recognition as someone walking in the dark.
If you use these light on you, the sinusodial motion of the Larson scanner will be superimposed on your walking motion and hopefully, you will be more easily recognized as someone walking. This would be in the principle of addition of waveforms and the Larson scanner will give you an additional variation of 13 cm to your natural motion. Thats plenty.
While i was very happy with the previous design (three in use) this iteration looks even better. the electrical properties have been improved, too - while the price kept the same. this is how i like tindie!
Besides working as advertised and looking well made it's an interesting device to show to friends. i also like the ecological aspect - using up old batteries is a good thing to do if you can not avoid using them. example use: one of these got attached with neodym magnets to a fire extinguisher in my lab, so it's easier to grab it in the case of an electrical failure.
Put on the side of a 19" rack holding computer equipment not only every nerd will notice it - the LEDs are bright and of rich color. did glue some small neodym-magnets to the backside to make it stick professionally :)
These are handy little lights, great as a night light for camping...as they're not too bright. I've stuck a tiny magnet on them so they can be stuck anywhere. I have also found a single full AA to last for many days, very efficient indeed!
I bought these to use in an area with poor lighting, not really knowing what to expect. They are a delight. Basically they switch on one the light from other sources dims. They definitely are a good way to use up batteries that otherwise apart spent. I have one light going for 3 days on what seemed to be a dead battery. The light is quite bright but not too bright. Great little items
This shield is fantastic... it allowed me to recover 7 busted ATTiny85 ICs with mangled fuses... the shield is really easy to use and handles both the 5V and 12V required to reset the fuses, all via the 5V input.
Also on top of that, Christos seems like he is just a really nice guy, very responsive and genuinely cares about the quality and usability of the products he makes!
Great little modules. Perfect, does exactly what I needed it to. Received in the UK in under 1 week! Amazing service and communication from the seller. Full and detailed documentation received in 30 minutes of purchasing. Cannot fault, will be buying more!
