I purchased the Lumenfix FF500 for my Proxxon BFB 2000 drill stand, it was delivered on time and works perfectly. I made a wooden plate to fix it to the drill stand and I am very pleased with the result, it lights the work area perfectly and I can highly recommend this product!

Works like a charm!

For Flex NodeMCU programmer BE (for ESP-12, 08 and 07)

Works as expected.
Some I/O pins are fitted with an LED, which is very convenient for quick testing purposes.
Only point of critic is that the soldering quality is messy.
A tip for a future version, also breakout the bottom pins for the ESP12E and F.

Great product!

Always love smd's stuff

For Flex Red Devil ESP8266 Programmer

I first got introduced to smd's goodies back when I found a posting about one of his older (red) esp12/esp07 programmers and promptly ordered one. I was having fits getting it to work and thought I must be doing something wrong. I contacted him and he quickly helped me remedy the problem. I've teased him ever since that he should make something to program 03's and in my most recent taunting I said if he was really smart he'd put an 01 programmer on it too while he was at it. He just sent me the link back to this bugger and I ordered one right away! It's nice to have one platform where I can talk to 5 different types of my bare-bones devices and two more if I ever decide to try playing with a 4 or an 8.
Great stuff, highly recommend and try to help him promote as much as I can. I haven't seen anything as versatile as this platform out there. I especially love how he makes the power a no brainer with a rectifier so you can't even hook it up backwards. My only complaint is the pending documentation. But he covers the basics in the description and is quick to answer any questions so I'll still give him a few stars on it there

Great bit of kit!

For Flexible NodeMCU ESP12, 08 and 07 programmer

I had made about 4 different jigs to program the ESP8266 ESP-12 modules. All of them were a bit hit and miss, with different problems. Finally, I decided to wasting time and money and I bought this.

It works great! Exactly what I need to program a bunch of ESP-12 modules. Totally worth the money, it's saved me many hours already! I just wish I'd gone down this route months ago.

Documentation is a bit sparse, and I it would be nice if it could all be powered from the USB connection, but, otherwise, it's perfect!

This thing is awesome!

For EMP sensor, detect lightning and other phenomena !

Bought a couple of these to detect lightning for a camera shutter control build. Seller answered several questions within a day of asking and answered well. I would suggest adding the tips he provided to the information for this sensor.

The sensor has both digital and analog output, if using digital out, breadboarding a circuit using an LED and an NPN transistor as a relay powdering an LED and a clicking an electronic lighter next to the sensor is how I tested to see if it were working. The circuit was based on the seller's reply when I asked how was I to test the sensor - it's not like I can wait around for a lightning storm in November.

If using analog just write a script to read the signal and use the electronic lighter for the test.
