Gosh complex – it was great in the above all the linkages – reviews technically to my mind are features, and synergy in using them. Seems to me reviews can be on how to use (introducing to a new audience), tea […]

@khaase interesting getting the LiSOCL2 activated.
My 2Cents is it would be good to characterize the 350mA pulse – and isolate it from the mega1284’s high impedance LiSOCL2. That could mean that for the “high impedance” (for a battery) LiSOCL2, the current draw has to be kept below a threshold, treated as a constant current source.…[Read more]

For electronics hardware – most people are used to shopping and then buying – simple transaction – however Open-Source Hardware at the board level can be different.
@ensign published https://www.envirodiy.org/tools-for-collaborative-solutions-to-water-challenges/
So, I’m interested in a discussion of how can OSH is used – Mayfly and other.…[Read more]

I ordered the cable. FWIW The folks that run Tag-Connect are very friendly!

I’ve been testing with Mayfly 1.1 and LiSOCl2 D batteries. Our package is using a Mayfly 1.1, and SD card, and a sensor on the switch power that pulls ~350 mA in pulses when its on.
I initially tried using 1S4P configuration with 95sq015 protection diodes with the intent of preventing heating from cell imbalances. That puts the Vin at about 3.4…[Read more]

Thank you for the link. I was googling for pogo pin grids, what a nifty widget.

The Mayfly v1.1RevB board uses a 6-pin Tag-Connect socket for the ICSP header: https://www.tag-connect.com/product-category/products/cables/6-pin-target
Previous versions of the Mayfly boards used standard header pins for the ICSP header, (0.5″ spacing on v1.0 and v1.1RevA, and 0.1″ spacing on v0.5 and older).

The Y511-A has a wiper motor that draws a little too much power on initial startup, so unfortunately even the newest Mayfly 1.1RevB still can’t power it directly. Our early 1.0 prototypes handled all the various 12v sensors just fine, but the voltage regulators on that prototype have been out of stock for the past 18 months, and we’ve been…[Read more]
Shannon Hicks replied to the topic Yosemitech Y511-A Wiper Problem in the forum Miscellaneous 1 years, 10 months ago
With the Y511-A sensors we have (that were purchased about a year ago), whenever you apply 12v to the power wire, the wiper spins continuously in one direction for 5 full revolutions and then “parks” the wiper blade in the home position. Then it pauses for a few seconds, then it performs the actual back-and-forth cleaning wipe motion (not full…[Read more]

Could you share ideas on how to promote open source reviews? How can journals like HardwareX be leveraged? Can you share more about Crowd Source and how that helps verify quality assurance? This is all highly […]
