Perfect

For Serial driver for large seven segment LED displays

Easy to Assemble. Quality board. Good layout with a lot of extra proto type space. Do wish the kit with parts version was still available as getting the parts takes some time and effort. Hoping the board is redone in the future with smd components. Would buy again!

solid product

For Serial 8-digit 7-segment LED display (Red, 0.56")

The hardware is top notch. I had to do a bit of digging around on his web site to find the example code.

Great little transmitter/receiver kit!

For 433MHz ASK RF transmitter/receiver kit

Dec. 28, 2021 (Update of an earlier review on Sept. 23, 2020)

The Tindie 433MHz transmitter/receiver kit is the best and most reliable one I've found. Previously I tried to use some similar components sold by other vendors, but the quality of those kits was terrible and many failed to work at all.

In contrast, the Tindie kits are better assembled and have worked well. The kit comes with a transmitter and receiver pair, both assembled on mini PCBs. Included is a coiled 1/4-wave antenna for each that helps increase the communication range.

Note: I've used about a dozen of these, all working very reliably. However, I did have a problem with one of the transmitter boards (apparently, it had a bad capacitor.) But after reporting this to the vendor, they sent a replacement kit immediately. So, a great product comes with great customer service -- the mark of a quality business. I give them my highest rating!

10/10 would recommend

For ESP8266 breadboard adapter

Packaged wonderfully with excellent care and as an added bonus the package was a beautiful purple color :^) I would definitely purchase again!!!

Great product.

For Serial 8-digit 7-segment LED display (Blue, 0.56")

First one had a small flaw, seller sent a replacement straight away, led display works perfectly....

Works well

For Easy pulse sensor based on photoplethysmography

I wanted a device so I could graph my pulse to show my doctor at the next appointment. They have taken an EKG but that was in the office. Some people have the white coat syndrome and that can affect readings in the doctors office.
This device allowed me to scope both the analog pulse and a digital pulse. The analog signal shows amplitude and a nice pulse. The digital signal shows irregular pulse better than the analog pulse. I put both signals on a dual trace scope so the relationship is very clear. A picture is then printed to take to the doctor.

H-V seven segment led display driver with spi interface

For Serial driver for large seven segment LED displays

Looks nice, but have not built on it yet, have not all components yet. Should be used for agility timing. A board for flyball timing facilities (EJS= electronic judge system) would be welcome, many in Europe could use one. I hope it will come.
Sincerely Steen Pyrmov.

Pretty damn elegant circuit

For Easy pulse sensor based on photoplethysmography

After unpacking the module I was able to get it up and running in a few minutes. At first I maintained it at factory settings and with a 4.5 Volt supply it behaved excellently. I Redesigned the PCB to a flexible SMD one for my application. I think the circuit is a pretty damn elegant example of good and esthetic design. I am impressed! My next step is to get a 20mm LCD screen to display, numerically, the pulse rate. I was able to get a digital output at 3 volt supply of three 1.5 V AA cells, but the current draw ~15mA was too much for a CR2032 cell and although it worked at first the circuit only worked for about an hour. I am thinking of powering he circuit with a LiPo 3.7 V rechargeable battery.

Solid product, does what it's supposed to do.

For EasyESP-1: A rapid development board for ESP8266

The board got here quickly. It's just a bit pricey, but you get a lot so I think it's fair. It all just works. I built a weather station with it in just a few minutes.

It's really handy to have both Grove and breadboard/headers. Makes it easy to hack together a circuit quickly with what you have on hand.

Liked it so much, I bought a 2nd one to have around.

I expected 0.36 inch digits, but i got gigantic digits

For Serial 8-digit 7-segment LED display (Green,0.56")

I expected normal 0.36 inch digits, but i got gigantic digits. So I can not use it for anything.

Works great!

For Easy Pulse Plugin: An Arduino pulse sensor

Works really well. The plastic holder holds well on the finger which makes all the difference in the data output from having only the light sensor.

Pierre | Sept. 5, 2018

Product does not work

For Easy pulse sensor based on photoplethysmography

Hi

I already have an Easy Pulse 1.1 sensor but the one I got from Tindie does not work...

what's the procedure to send it back?

Thanks

Pierre

Aristos | April 4, 2018

Works great

For 433MHz ASK RF transmitter/receiver kit

Just bought this and am using it with an Arduino. Works great! Use the "Virtual Wire" library that Arduino provides and it is really really easy to use.

Catalin | March 8, 2018

Good design, but inconsistent manufacturing

For Easy pulse sensor based on photoplethysmography

I bought two units and while trying to bring up the first one I noticed that it was not functional. Visually comparing the two units, I quickly found that the 2N3904 transistor was missing on the non-functional unit. Upon soldering the right part on the board, full functionality was achieved. Documentation could be a bit more detailed in terms of schematics and layout.
As a product, it would have certainly received 5 starts if it wouldn't waste me almost an hour to find the problem, get the part, solder on PCB, and retest.

Josh | Sept. 19, 2017

Nice bigger board to easily get to everything

For ESP32 (WiFi/BLE) Development Board

Well built and good solder. Powders right up. I am kind kicking myself for not ordering more. A great starter for iot and no doubt great for those more advanced.

Werner | July 20, 2017

Nice PC Board. Good design

For Serial driver for large seven segment LED displays

Good product, helpfull for 7 Segment high voltage application . A little bit more schematic wuld help a lot

Matthew | June 21, 2017

The product works great

For Serial 8-digit 7-segment LED display (Green,0.56")

This worked great. Though I blew up one connecting it to 5v line instead of 3.3v. It is not listed in the doc what the voltage of VCC should be.

In case any one needs to know it is 3.3v.

Response from Embedded Lab | June 21, 2017

Hi Matthew,
It works safely at both 5V and 3.3V. If you blew up one, the reason might be something different.

Thanks,
Raj

Serial 8-digit 7-segment LED display (Blue)

For Serial 8-digit 7-segment LED display (Blue, 0.56")

Very well packaged and does not feel cheap at all.

I recommend that seller 100%!

Thanks a lot!

Nice pcb, but now requires surface mounted caps & resistors

For PCB for serial 7 segment LED display

The product works extremely well. However, it appears there was a design change for surface mounted capacitors and resistors and not for discrete parts that fit through holes. This makes it difficult and ugly for hand soldering parts. The photograph shows the previous design with conventional parts mounting.

Murat | Dec. 3, 2016

excellent product, excellent service

For Easy pulse sensor based on photoplethysmography

I use this PPG sensor for a project. It is a great product with digital as well as analog o/p and works smoothly. The seller, Raj, responded very quickly to ensure I receive it asap.

Gavin | Dec. 3, 2016

great product!

For LED display module (PCB only)

This pcb is excellent and saves so much time on wiring! The stacking of LED displays are flush and no gaps, just the way I want them to look.

easy pulse

For Easy pulse sensor based on photoplethysmography

after trying to figure out the problem with my easy pulse, i e-mailed Raj and he was a great help for me, i explained the problem i had he walk me step by step what to do, my only probelm was i forgot the shunt jumper between the EN pin and VCC pin and finally i was able to make it work

These a re Great! Work perfect and easy to see / update

For Serial 8-digit 7-segment LED display (Yellow)

I'm using 3 of these on a beaglebone black with SPI and they are chained. Talking at 1 Mbps and needed to keep the DIN, Load, and CLK lines from the bone at 3.3v so I'm using a level shifter to take those lines from 3.3 to 5v and powering these with 5 volts to stay in spec with what the maxim chip wants. I'm using Red, yellow, and green to show RPMs, Torque, and Horespower calculations live for a chainsaw dynomometer I'm doing the electronics for some chainsaw enthusiasts I share that hobby with. They are doing the mechanical stuff and I'm using a hall effect sensor and magnet on a shaft to do RPMS which inputs to the eQEP encoder hardware counter in the bone in the single clock line count mode along with an A/D chip that uses i2c to talk to the bone with a load cell to read the force from a torque arm the saw will drive. Plan to save the data in RAM so I can plot graphs and such like any other car dynomometer. Very happy with the results. Here's a youtube video I made to explain my bench tests to the other guys working on my project you can see the displays in action. They are even easier to read in real life than on camera:

Excellent Quality

For ESP8266 breadboard adapter

The Board is excellent quailty, it was shipped fast and arrived nicely packaged. Made it much easier to program multipule chips. The printing on the board is very readable. I was very satisifed with the purchase.

Leo | Dec. 2, 2015

Excellent product and support

For TrH Meter Kit

The unit does not come with any instruction but can be found on their web site. Had a problem from my own doing, returned unit and was fixed fast and free. Don't see that service any more... Will definitely buy from again. Thank you for the support.

Aslak | Oct. 27, 2015

Just as described, solves the task very well.

For ESP8266 breadboard adapter

Needed to have the ESP-01 connected to a breadboard for a workshop. This thing does that quite easy.

Ordering, payment and follow up was unproblematic. Shipping was fast.

Francesco | Oct. 11, 2015

Professional, fast and excellent quality

For Serial driver for large seven segment LED displays

I've purchased two boards that he shipped immediatly, people tell me that shipment to Italy was very slow (about 1 month), but I received the boards after 10 days, with a good tracking service, and the boards were very very good, excellent quality. He was very helpful with me and if I'll need other products no doubt he was a trusted and professional seller.

Darrell | Oct. 6, 2015

Just the thing you need for the ESP8266

For ESP8266 breadboard adapter

Searched quite awhile looking for a good way to use the ESP8266 with breadboard projects. I've seen posts where they say "just build one" but it's really not that easy to do it correctly. Then I found this product ... perfect, exactly what you need to easily mount the break out pins. Quality of product is excellent, well thought out and good materials used. Recommended!

Marcel | Sept. 10, 2015

Solid and nifty

For ESP8266 breadboard adapter

Qualitiy is high. I mean, it is a solid, sturdy PCB. Letters on it is very good thinking! You need those to prevent mistakes and blowing yoru ESP's.

Rogerio | Sept. 2, 2015
