What new module(s) for Gadgeteer?

Triac/Optocoupler Dimmer - Project Guidance - Arduino Forum

Is this targeted the phase controlled modulator module I suggested?
I quick glimpse over the schematics does not show zero point synchronization which is absolutely necessary for motors.

@ Reinhard Ostermeier - Zero crossing detection is done in the opto coupler (MOC3041)

[Architect]

@ Reinhard Ostermeier - Would the “zero volt on” solid state relays help to solve the problem?

Now I see it.

Never heard of such a thing !?

I just received one of these laser rangefinders, I will post a code snippet for it soon. be aware that its range is only 20> range >240 cm.

Looks like a nice one. However, I want something that I can safely point towards people.

Then you should attach a laser glasses thrower to it

btw. Class 3 or 3M is safe according to the specs, because the eye closing reflex is fast enough. This module is 3a, not sure what’s special about a.

Personally I wouldn’t point it against people anyway.

Yea, I’m pretty sure that excuse wouldn’t hold up in court

I like the idea of @ njbuch. A simpler version is just a coin battery holder for a RTC battery to connect to the proper socket, that would make it easier to use the RTC, without having to figure out how to get a breakout board, solder up or mount a coin cell, etc. Does not seem a driver would be needed…

@Blue Hair Bob

I second the idea of a simple Coin Cell plug. This is a clear need. I will pre-order several.

Do we have the same idea ?

How about a replacement for the power supply board with built in lithium battery, charger and gas gauge.

That supports solar charge and interface to read all stats. And supports several types and sizes of batteries.

Like these?

I recently bought one of these Thermal Array Sensors…

http://www.futureelectronics.com/en/technologies/semiconductors/analog/sensors/temperature/Pages/5020660-MLX90620ESF-BAB-000-TU.aspx

For $60 you get a high-resolution 16x4 thermal array and a simple I2C interface. I can share my driver for it.

(This works with a supply voltage of 3.3v and consumes 9mA)

Please share, and a module for this would be cool.

I will, along with the full build instructions for my project. My goal with this project is to land on HackADay’s front page again and link people back to GHI and NETMF. …To grow the community.

@mhectorgato

Are you thinking of the GHI US3 modules? Or the other non-gadgeteer ones?

if non-GHI, what type of connectors- JST? Screw Terms? Something else?

if GHI, any reason the attached board wouldn’t do the trick? I didn’t label them - x1 = mainboard input, x2 x3 and x4 go to the sensors.

Non US3 modules as those have a resolution about 1cm and I’d prefer 1mm. I was thinking hookup would be via a JST connector and I was thinking of these types of sensors
https://www.sparkfun.com/products/11307 and the idea is you can attach whatever sensor works for you needs beam width etc.

If you are looking for a reliable pH Sensor check out Atlas Scientific’s pH Sensor. I have been using one in my Pool Monitor for a while now. It is reliable and has a simple Serial Interface.

I am using this with a Cerb 40 II in pure NetMF. It works great. They are not cheap ($105 for a pH Kit).

I have written a NetMF Driver for the module that I created. They have a whole line of sensors as well.

Living close the manufacturing plant, I have had the opportunity to visit. The Tech support is top notch as well.

I’ve always been impressed by the Atlas stuff and at $600 for a full kit https://www.atlas-scientific.com/product_pages/kits/sds-kit.html your module sounds very interesting.

They have some cool stuff like this water sensor http://www.cooking-hacks.com/shop/new-products/water-leakage-liquid-detection-sensor-line , but for me its got to have a Gadgeteer socket on it

[Duke_Nukem]

Of course bio-medical is always nice, like a An electromyogram (EMG) measures the electrical activity of muscles at rest and during contraction or The electrocardiogram (ECG or EKG) is a diagnostic tool that is routinely used to assess the electrical and muscular functions of the heart and a nasal airflow sensor and galvanic skin response sensor would be nice for when we are trying to scare the crap out of the monkeys eg http://www.cooking-hacks.com/shop/sensors/airflow-sensor-breathing-ehealth-medical

No, the lipo-rider-pro is like a black box, the code cannot control or read charging etc. in a real setting this is a requirement. Furthermore, only lipo batteries supported.

Good point, but you can read the current charge on the Energy Shield (A0 Pin). I’d love to see GHI do a battery (with LiPo support) module.
