If you have a LitePlacer then you want this!

For TMC2209 TinyG upgrade for LitePlacer & OpenPNP.

Amazing improvement to the motor control of the LitePlacer. I don't even hear the stepper motors anymore. Gone is the ringing and buzzing when the machine is idle. I also bought this to help with the migration to using OpenPnP, since it has jumpers to swap the inputs of the Z limit switches. Assembly was very easy and the instructions are very good. Be sure to buy the PCB with the SMD components already soldered, very much worth the small extra cost.

Great Product worked exactly like I'd expected

For Resistance Decade Substitution Box Kit

It took me a couple of selectors to figure out the 'easiest' method for me to solder on the resistors.
It works great, I think I need to find new connection wires to reduce the impedance they add, as mine is at 1.6ohms zeroed out.
I like that instead of a bunch of knobs to read and add up, its a quick read for exactly what I've set the resistance to.
Everything I'm looking at doing needs mega Ohms or greater, so I don't see an immediate issue/need to resolve it.
There was no project box available when I purchased mine, so I designed one that can be 3d printed for those with that capability. You can find that over at thingiverse as thing:5260681.

Cool, thanks for posting the box on Thingiverse.
(already added to my collection!)

Great addon for a low price... just minor issues

For TMC2209 TinyG upgrade for LitePlacer & OpenPNP.

Hi,
I bought this upgrade to make my Liteplacer more silent and less hot.
WORKS!
The full set has been shipped fast to Germany.
The Wiki page helps to build it.
Good: The SMD Parts has already be soldered, so get not just the PCB, but with all parts.
Worth every cent, do not buy PCB only.

The only minor downsize: The add on board does not align to the original mount holes,
so mechanical some work (3D printing, or hot glue) is required.
But: The electrical connection are well done.

Thanks for supporting the comunity.

Hi Marko

Thanks for the kind words & glad you like it.

Regarding the mounting Holes: When designing initially for my own setup, I had envisioned using zip ties to supplement the Header mounts. In the end, I felt that additional mounting support beyond the headers was not required (for me). However, for the next rev of the PCB I will look into this further to see if it can be enhanced.

It was a pleasure purchasing from Tindie. Great product!

For 10MHz OCXO Frequency Standard Module or Kit

The Tindie OCXO module/kit is a great little 10 MHz frequency standard. I bought the fully assembled, tested, and
calibrated version. Through email Tindie helped me figure out what additional connector cables I needed to connect
to the additional four outputs. My order was shipped promptly and I received it fairly quickly considering it was an
international shipment.

Upon receiving my order I hooked it up as per the instructions. I checked all the outputs using an oscilloscope and
frequency counter and found all working as expected. I also found that one really has to pay attention to having the
50 ohm termination on the receiving end of the cables. Without the proper termination the waveforms will not look
good at all. I found that I needed to use a 10x, 5pF probe with my Tek 465 scope to see a good waveform at the end
of a 1 meter length of RG-58 having a 50 ohm termination. I also found out that the sweep on my Tek 465 definately
needs calibration!

My plan is to mount the OCXO in a small enclosure with its own power supply. I want to include several decade
dividers to provide several fixed frequency outputs. I also want to have a switch selectable output for the lower frequencies. I may also add a variable width pulse output for the lower frequencies as well.

It is really nice to be able to finally find a good affordable frequency standard. Now I may be able to calibrate some
of my test equipment so function generators, oscilloscopes, and frequency counters may actually agree with each
other.

Thank you Tindie!

Hi Kedric
Thanks for the feedback, much appreciated :)

Goes to six nines in a few minutes

For 10MHz OCXO Frequency Standard Module or Kit

Board arrived safely at USA address, in a padded bag, a week after the order.
This is a completely assembled unit with no calibration (option A2).
After a few minutes the output measured 1.000000 MHz and the board draws about 220 mA.
Everything is exactly as advertised and this is now by far the most accurate clock in the lab, to be used to calibrate or characterize other instruments.

Thanks!

Difficult extenders to find. A quality product.

For Extender/Riser boards for 5345A & similar testgear

Excellent service for a product not available any where else. Extremely satisfied with these quality products.

Worked as described

For 10MHz OCXO Frequency Standard Module or Kit

Bought 2 boards populated with everything except the OCXO. I fitted my Bliley OCXOs and the PCBs work well. Shipping was fast, and the packaging was good. Overall very happy with my oscillators. The adjustment is very sensitive, perhaps consider a larger number of turns trimmer pot for more precise adjustment.

EDIT: Thanks, I didn't even look, just assumed I had Rev C. You are correct of course, these resistors on Rev D allow me to solve the problem completely. As you correctly point out, most references will want around 2.5V, so I will probably change my pot to a 10K or 20K pot instead of the 50K pot. This also increases the number of turns per Hertz. Please note: I am being really, really picky here, mine is tuned to within 10 millihertz straight out of the packet.

Glad they are working out for you & thanks for the feedback. We will give your suggestion some consideration, for the next revision of the PCB.

Some thoughts:
- I believe you have the latest Rev_D of the PCB
- In this rev, you can get more sensitivity by replacing R1&R3 with higher value resistors. Ideally, they should have the same value, but that will depend a lot on whether the Vfc for your OCXO is close-ish to 2.5V (or nearer one of the extremes) They are in series with the POT and by increasing their values you can effectively increase the adjustment resolution, by reducing/narrowing the adjustment range. I will also email you the latest schematic directly. (let me know via PM if you need more info on this)
- FYI: In my experience with these OCXOs, including the Bliley, the adjustment sensitivity is sufficent to 'tune' within the operation range of this class of OCXO.

UPDATE: I just checked and it looks like there are pots with more turns & the same footprint available. I will order some in to evaluate with a view to offering them and an upgrade option. So not need to wait for a new PCB revision :)
Existing users, can simply desolder & replace the existing one, if required.

Great little module, perfect for prototyping

For SendIR, advanced Infrared emitter module (IR)

While you could definitely embed this in your end-project; I plan on using it for speeding up prototyping and to sort of remove a some human error. It is well built and documented. Looking forward to ReceiveIR.
Shipping to USA was fast.

Hi Josh

Many thanks for the kind words...

FYI: "ReceiveIR" is already available....but called "DetectIR" and can be configured with many IR receiver options.
(Unfortunately, it is currently only listed on our own website. When I get some spare time I will also list on Tindie along with our wider range of IR modules)

There ia also another "RecieveIR" module available, called A.IR Shield Rx. This is a dedicated shield for AnalysIR and plugs directly into platforms such as UNO or breadboards. However it can also be used for other purposes and features both a standard IR receiver & IR Learner in one very compact module. Allows signal recording & Carrier frequency measurement. Again only available via our website.

I reallly must get more of these IR modules listed on Tindie.....

Module works great, as described. Nice product.

For 10MHz OCXO Frequency Standard Module or Kit

Works great. Placed in enclosure with regulator, and will use as external reference for vintage HP frequency meter.
..tried to upload jpg of mounting in enclosure, but "Upload failed"..

HI Matthew

Thanks for the feedback.

I would be interested in seing the photo of your enclosure. If you email it to me (you should have our direct email address), I will see about getting it uploaded.

good kit

For 10MHz OCXO Frequency Standard Module or Kit

This is an excellent and inexpensive way to provide yourself with a solid 10Mhz frequency standard. I got the board populated with all the parts less the OCXO which I got from Ebay. I bought the ISOTEMP OCXO 131-100 with a date code of 2004 . Aside from the fact that the Ebay seller mislabled the pinouts on the ocxo, It worked right off the bat once I checked the spec sheet.
Clever product, well made and it did the job for me.
