GPS clock in Sweden

For GPS Clock

My clock works fine. I bought a new GPS antenna to receive extra satellites (e.g GLONASS). In northern Sweden we often find that it is good to have GPS antenna with ability to capacity to catch many satellites. Otherwise I am very pleased.

Response from Geppetto Electronics | May 9, 2021

Unfortunately, the SkyTraq timing module does not support GLONASS or any other non-GPS satellites (it does support GPS WAAS systems, where they are available).

GPS does not work

For GPS Disciplined OCXO

I ordered two of these units. Both loose every 5 - 10 min the GPS lock, which makes it impossible for the VCOCXO to lock to the GPS. I had some nice but not very helpful conversation with the developer about it. Other GPS controlled oscillators (Signalhound SM200, L Bodnars GPS clock, uBlox LEA-M8F) had no such problem at the same spot with the 4 (!) different active antennas tested.
The build-in OCXO is pretty precise and if no absolute precision is required the frequency change over time is minimal.

Great little clock, interesting circuit

For GPS Clock

I would imagine this could be combined with the broadcast time signal to automate daylight savings as well. In any case my only gripe was the need to run back to the web to get instructions. Even a slip of paper or a mark on the rear containing a link to a PDF manual would be appreciated.

Response from Geppetto Electronics | June 29, 2019

The firmware will do DST correction with the current rules from the EU, USA, Australia and New Zealand. If any of those rules change in the future, then it is possible to perform a field firmware update.

Good experience

For Raspberry Pi Zero Clock

Not connected yet to Raspberry Pi Zero W. No problems to solder except by mistake I mounted one display upside down.

Works Great

For GPS Clock

It displays time if it locks to GPS signal. However when no GPS signal is present, it does not display time but a "No GPS" message. It would have been better to continue to display time with a note that there is no GPS.

This concept is called “holdover” and I wrote a project log about it on the project page: https://hackaday.io/project/18501-gps-clock/log/70091-whither-holdover

Good product

For Toast-R-Reflow Controller

Love the end result. The package with the two kits (power and controller boards) came with no paper document. I searched and found the assembly instructions on-line but it would have been nice to get an internet address.

I used a Black and Decker oven (TRO490BC - 1200W) and it works like a charm.

Good product - no documentation.

For AVR ISP Pogo Adapter kit

The pogo adapter works as designed to connect and program ATMEL chips. The product did not come with any documentation. One had to review pictures on the tindie website and carefully read the markings on the PC boards to derive the assembly of the components.

Response from Geppetto Electronics | Nov. 6, 2017

There is documentation available, including assembly instructions under the “Documentation” link on the product page here on Tindie.

GPS Clock - a GREAT addition to my amateur radio shack

For GPS Clock

All of the controlled clocks in my home are of the Atomic clock variety that receive a signal from WWVB on 60 kHz from Fort Collins, Colorado: https://www.nist.gov/pml/time-and-frequency-division/radio-stations/wwvb . I live in SC, so the only way I can reliably sync them is to move them to the Western side of my house near a window at night, which I do weekly. It is wonderful to have a clock where I just need to place the GPS puck outside my window, and be assured of the 100 ms accuracy every split-second of the day. I purchased the clock fully assembled. It's options allow customization of the clock in terms of LED intensity, Time Zone, Daylight Savings Time, 12 vs 24 hr, display of the tenth's of seconds display, and more. There is no significant documentation provided in the package, but it is on the Tindie website. Setup is fairly intuitive, though. No communication was necessary between me and the seller. Shipping was very prompt, and packaging was good. I realize that this began as a very simple project, but it definitely has a permanent place in my ham shack. - 73 de JIM N2ZZ

Response from Geppetto Electronics | June 1, 2017

Thank you for your kind words!

I do have to point out that I've had to revise the specifications of the clock's accuracy down to 200 µs instead of 100 µs. The code in the interrupt handler for the PPS took longer than I had estimated, but the 200 µs figure is the worst-case accuracy measurement.

Neat clock!

For Crazy Clock

With the increasing interest in Mars exploration I thought a clock that keep Mars time would be neat to own. I made up a clock using a photo of the planet on a acrylic base and would like to report it's keeping outstanding Coordinated Mars Time! I'm appreciative that a colck like this is available and at a very reasonable price. I'm very happy with the quality and the shipping time was excellent. Thank you!

Good product, did the job.

For Pi Power

No complaints with the product, did what expected and allowed me to power my Pi from a AC adapter rather than USB. Two suggestions: one include a note in the documentation that states the minimum pins that need to be connected or soldered to connect the Pi Power and Pi (yes it can be worked out from the schematic but for the sake of an extra sentence doubt could be eliminated); the second suggestion would be to provide two pins to allow easy access to the input voltage, in my case I wanted to also power a 12v relay, I soldered two wires to the bottom of the Pi Power but easy access pins would be nicer.

Response from Geppetto Electronics | Sept. 20, 2016

The list of most important pins to solder a good idea. I've added that note to the user guide page.

Jay | Feb. 18, 2016

Fine product.

For USB µISP

The USB uISP programmer is a good product at a good price, and it was delivered quickly. And once I got it configured, it worked.

However, I had never seen or used an ISP programmer before, so for me it was a little difficult to find the necessary documentation and software. If the vendor would just include a little slip of paper with URL's of appropriate resources, it would be a perfect product.

Great product.

For EVSE Tester

Works as intended. Shipped to Denmark with fast handling and in mint condition on arrival.
Any chance we get to see a 3d printable case?

Response from Geppetto Electronics | Nov. 30, 2015

Unfortunately, I don't really have any 3D modeling skills. However, the display is a standard 80x36 mm one that ought to be well understood by this point. The rest should fall out in a pretty straightforward way, I would think.

The Whole kit Works a Treat [although could do with more]

For Toast-R-Reflow Power board kit

The Whole kit Works a Treat although it really could do with the ability to store multiple profiles and ideally lean a profile. I did have a number of issues with thermocouple however i believe that was more to do with the probe then the kit its self. Either way. it does what its meant to, SMD reflow solder and it does it well.

Response from Geppetto Electronics | March 27, 2015

Thanks for your review!

The model II controller has multiple profiles, though at present the only way to add more is to edit the firmware source.

Some other profile provisioning mechanism for model II is TBD. The model I controller, however, doesn't have enough free space.

An 85% solution

For Magic Trackpad Plugger

The Magic Trackpad plugger could be considered an 85% solution. By that I mean that it works about 85% of the time. It often disconnects and then reconnects. It is nice not to be dependent on batteries.

Response from Geppetto Electronics | Dec. 1, 2014

I've had better luck with mine, but I agree the current iteration is incomplete. What the kit needs is a replacement for Apple's plug that has a hole in the middle to accommodate the wire. That, unfortunately, is TBD (I have zero 3D modeling skills).
