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

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.

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.

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.

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

The product works great

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

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)

Very well packaged and does not feel cheap at all.

I recommend that seller 100%!

Thanks a lot!

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.

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

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.

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:

Thanks for making these and making them so easy to get!
Pleasure dealing with embedded-lab.com and Tindie.

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

Very nice

For ESP8266 breadboard adapter

Very nice and usefull adapter for usign 8266.
It fits the protoboard perfectly and reduces the number of wires/jumpers and clutter.

Søren | Aug. 5, 2015

Sure its good, but didn't recieve it...

For ESP8266 breadboard adapter

I'm sure your product is very good, but I just didn't recieve it ;-)

Hope that we can figure out what went wrong..

Sujay | July 15, 2015

great ESP8266 adapter. note the orientation of the board

For ESP8266 breadboard adapter

A simple esp8266 breadboard adapter. Make sure you note the orientation of the esp8266 board with respect to the adapter.

George | July 15, 2015

Works as expected - satisfied.

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

Ordered from tinde on-line and all arrived in a couple of days.
Purchased LED units 2 in green and 2 in yellow. Both types operated with no issues.
Noted that when these are placed next to the green identical units that the yellow is much brighter.
Can adjust with the intensity command as desired.
Using an Ardunio Mega via a serial link.
No documentation is supplied (one star) - not an issue.

Pierce | June 11, 2015

ESP8266 breadboard adapter works well with clear pin labels

For ESP8266 breadboard adapter

In addition to making the EXP-01 breadboard compatible, the pin labels are very easy to read. So, no more looking back at documentation just to connect to GPIO or flash firmware. The power supply filter capacitor is nice to have as well. No documentation needed

Abraham | May 20, 2015

Amazing

For ESP8266 breadboard adapter

This little board has one job and it is fantastic at doing it! I love it when engineers remain feature simple. It's perfect! Recommending to everyone I know!

Spencer | May 8, 2015

Works perfectly for breadboard prototyping

For ESP8266 breadboard adapter

I've used a few of these to connect the ESP8266 to Arduino for super reliable communication. With the recent Arduino IDE compatibility, I've started making 3V native sensors using the ESP8266, this adapter, and DHT22s to log temp and humidity throughout my house. This just works great.

Daniel | May 4, 2015

Nature & Embedded Lab love simplicity - a great product!

For ESP8266 breadboard adapter

A simple elegant solution - the intent was to make the ESP8266 easy to use and it does that well without inflicting fatal damage to your maker budget. A quality product and shipped quickly - what's not to like?

Andrew | April 21, 2015

Flat out awesome, great support

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

I bought 5 displays and absolutely love them. They're very easy to use and look great. The seller was great to work with and supremely helpful in resolving issues. One of my displays was mounted at a slight angle and he fixed it for me. I also requested one of the dual-row displays in a color which wasn't listed and he was happy to accommodate. The only negative thing I have to say is that the double row display is a slightly different color than the rest due to lot differences in the display modules — not something that will impact most orders, but something to be aware of if you are ordering custom items.

Russ | April 9, 2015

Works well

For Easy pulse sensor based on photoplethysmography

I added an external "threshold" potentiometer in parallel with the on-board potentiometer, so I could have the entire board enclosed and a large knob to set the cutoff.

One problem, though: the fingertip sensor makes my fingertip go numb after 10 minutes. I am running experiments which can last up to an hour, and for which I need both hands, so I need a sensor which can (for example) be attached with a velcro strap around the wrist. Is there a way to use the TCRT1000 reflective optical sensor, which is used in version 1 of the board? Do I need to get that version of the board in order to use the reflective sensor?

John | April 4, 2015

Easy to use and worked first time

For ESP8266 breadboard adapter

The standard version of the ESP8266 is difficult to use with a Breadboard. This adapter makes the ESP8266 easy to use and it worked first time - what more can you ask?

Shipping was also exceptionally fast.

Todd | March 25, 2015

Great product

For General purpose experimenter board for beginners

The easiest way to bread board an arduino project. I bought four, and they've been "borrowed" already by other members of the team.
