Nice little tester

Mine had some dry joints for the battery holder and it had popped off during transport. But a bit of solder fixed that and it works well especially for all the tiny surface mount LED's I wanted to experiment with.

Hi Eric,
I so sorry to hear that. This never happened with any of the testers I sold. Happy to know that you fixed it. Let me know if you need any part.
Regards

Excellent led tester!

Does its job. Shipped quickly. Well made. Conveniently sized. Now I'm adding sentences to get over 100 characters. Thank you.

Very simple device, but perfect for my requirement

I just needed something resilient to test a large selection of LEDs and I could not be bothered to make something myself. This product helped me to sort through the plethora of devices I needed to assess, which was very helpful.

If the creator is thinking of any upgrades, I would suggest a switchable constant current source and a larger battery voltage to test LEDs with larger forward voltages, but that shouldn't detract against this product.

Hi Carl,
I'm glad you found it useful. Next version will for sure have a constant current source and a variable voltage because a lot of customers asked for the possibility to test high power LEDs. Also going to add the possibility to test serial LEDs like Neopixel and ws2812b like LEDs (I enumerated 5 variants right now).
Thanks for your support.

Super handy little board!

I love stuff like this, handy little boards that just make life easier. Now it's super easy to quickly check out LEDs. Thanks for making this!

Great little boards

Nothing better than a simple well-made device that works to make your workflow go smoother. Do you need an LED tester? No, it's not hard to test an LED, but this small board will easily cut your time when troubleshooting or working on several things at once. Less time fiddling means getting more done, and this small unobtrusive board will definitely be a welcome addition to any toolbox or bench. Shipping to the USA during the pandemic was reasonably quick, but of course this is extremely conditional these days.

You'r welcome. Glad you find it useful. As for the delays, unfortunately they are completely out ouf my control.
Thanks for your support.

Nifty little LED tester!!

It really helps identify polarity and color of loose LED parts I have laying around on my bench. I like that I can hook up external power for higher voltage LEDs as well! I'll probably order a few more to keep on my other lab as well!

The shipping took 6 weeks but I don't complain. I fully understand we are in the midst of a pandemic, so I'm grateful it arrived at all!!

Thanks, Thanos

Thank you for the review. I'm glad you'r happy with it. So sorry for the delivery delay, it's out of my control. It was used to take only 3 or 4 days, with the pandemic, I'm really unable to provide any precise guess. Only thing I can control is to send the product as soon as the order is recorded. Delivery all over the world is chaotic. Sorry.

Must Have!

I ordered two of these, the seller was very helpful, they arrived very quickly and have been really useful.

I've used mine loads in the short time I've had them, it's especially useful for getting the SMD device polarity correct, nothing worse than checking the base of the LED for the polarity then it pinging out of the tweezers!

If you've got a 3D printer you can print yourself a base to mount it on (sorry blatant self plug, it's something I designed) https://www.thingiverse.com/thing:3098120 to help organize your LEDs as you test them and it makes the through hole tester a little easier to use.

The only improvements I'd like to see would be holes for M3 machine screws rather than M2's as M3s are more commonly to hand and/or some stick on feet, perhaps the LED symbol on the silk screen to reinforce the + / current flow direction, but otherwise, it's perfect for the job and incredibly handy to have.

Hi Stephen,
Glad that you received your LED testers. Thank you for these nice words. It's very encouraging.

Very nice work with the 3D printed base. Really nice work, congrat!!!

I'll take into consideration the holes dimension remark.
Thank you for your feedback.
