I bought the 2018 Calendar and am very satisfied with it. I definitely recommend purchasing the 9/12 volt USB power cord when purchasing the Calendar. They go perfect together. I will definitely be buying more of these calendars. One just isn't enough for home, office and workshop!!!

Well-built and useful, a real time-saver

For Pogo Pin ICSP SPI Programmer Adapter

This pogo adapter is handy and ideal for development work or production programming in situations where a regular 2x3 pin header may not be fitted yet, or at all. As well as fitting an unpopulated pin header footprint on a board, this adapter also works well on plain test pads on the board.

Exactly what it looks like.

For Pogo Pin ICSP SPI Programmer Adapter

This works a charm. Product shipped quickly and without any issues.
0.1" pogo pin spacing confirmed by the product developer. Couldn't find the specification detailed on the page, but seller answered questions quickly.
Thanks for the work!

Perfect little tool to get rid of some old power bricks !

For USB912

...and put USB ports to more of the good use. 9V/12V for me is the most reasonable since most of the devices operate on this range. Totally recommended!

Does what is says on the box

For USB912

Drives my WiFi router, but not my small PC speakers.
Can't deliver much power, but that is not the products fault, it's a USB limitation.

Great and compact little board!

For ESP8266 FTDI and breadboard adapter with 3.3V reg.

When I first saw this product I knew I needed to try it out, and I am glad I did.
Once I added a separate switch for enabling "Programming Mode" these beauties really show their value.

Originally, I built my own little board to program and for use with a DHT temp/humidity monitor and I knew there had to be another way.
That's where these came into my collection, and with the accompanying FTDI boards they make a great pair.

I wish there was some more documentation, but the other reviewers seemed to fill in some of the gaps they I needed to know.

I will order these gain, should I need something like these again.

Very convenient adaptor

For ESP8266 FTDI and breadboard adapter with 3.3V reg.

I just aquired the "ESP8266 FTDI and breadboard adapter with 3.3V reg." together with an FTDI-adaptor. So now I am up and running with the ESP8266,
Thanks to that adaptor, I avoid soldering ( an own adaptor) and saved a lot fuzz with wires, components and bad conncetions on the breadboard, I can concentrate on the in less then a weel it arrived from USA to Madrid, Spain. I asked for some additional info ( ie. internal diagram) and recieved it promptly. so at least in my case I recieved excellent support.

Nice set of tools for working with the ESP8266

For ESP8266 FTDI and breadboard adapter with 3.3V reg.

I bought the set of all three boards - breadboard adapter, FTDI and ESP8266, so I had the breadboard adapter made with female pins for the FTDI port to match. Everything arrived quickly in separate anti-static bags inside a nice little box.

The combination works very well on my Mac; I plugged it onto a mini-B USB cable and was immediately able to connect to the ESP. The only issue I've found was that the FTDI adapter isn't happy on my Linux machines, likely a driver problem.

This kit makes for a handy way to play around with the ESP8266 or incorporate it into a breadboard; it's also a reasonably convenient setup for re-flashing, you just need to add a jumper to hold GPIO0 low (to ground) while hitting reset in order to put the chip in programming mode.

Great little device to support testing and prototyping

For Pogo Pin Adapter Row of 2 to 30 pins

I have ordered Pogo-pins from Femtocow in the past and immediately requested more configurations. By offering pogo pins in 1x3 and 1x6 factors, I can test my breakout boards without having to solder on headers or play that little game where you place a 1x6 header into the breadboard and torque / push the breakout in hopes of making a solid connection on all pins. Very well built and reasonably priced.

One more thing, I had an issue with the post office's delivery to my apartment complex. Femtocow did a great job communicating with me and he completely addressed my issue. It is great to know that this Tindie seller not only makes a great product but also delivers great customer service. Highly recommended.

Simple but Awesome Implementation for ICSP

For Pogo Pin ICSP SPI Programmer Adapter

This device solves a simple problem. I need to program my boards with raw ATMEGA chips using an ICSP socket on the board. But I only need to do this one as I can use the FTDI connector for subsequent programming. With this device, I don't have to solder a socket onto the board for a single use. Brilliant!

Great!

For Printrlight for Printrbot Simple Makers Kit 1405

This gadget solves 2 major issues with the Printrbot Simple: bed area lighting and extruder cooling.

The all-metal extruder is very prone to overheating on long (<3 hour) prints. This happens because the extruder motor overheats and conducts heat into the extruder assembly, which inevitably ends with the hobbed bolt overheating, melting the filament too early, and ending up with filament wrapped around the hobbed bolt and a failed print. The Printrboard lets you mount a 60mm fan (I used a 50mm fan and it still mounted just fine) that blows directly into the extruder, which keeps it perfectly cool for any print duration.

The LEDs that light the bed area are nice - especially if you're printing with dark filament in a dark room. I find the LEDs a bit bright and don't necessarily light the build "attractively", but they more than serve their intended purpose (it's a wood 3d printer kit, not an Apple product after all).

I wish Printrbot would just purchase a gross of these and bundle them with future kits. It's that essential.
