News - Modkit Micro
about 5 years ago
Yep - you’ll get the desktop copy in July, no additional payments needed. Thanks for being patient! :)
Thanks for the encouragement! We will be anticipating projects from your dad…
The short answer is that we originally did a Kickstarter campaign to fund initial development, whereas our current campaign is to actually launch the product resulting from that development.
For more info, we posted an update for supporters of the original campaign explaining how the two Kickstarters are related. We also have a FAQ on our current Kickstarter page for more clarification. If you have any more questions, the best way to reach us is by sending us a message on Kickstarter or by posting a comment on the update we mentioned above.
Thanks so much!

Thanks for pointing out the compatibility. If you go that route, it would be great if you posted an example sketch here. That is an advanced use though and even with the Sparkfun redesign (they switched from a PIC to the atmega328) most beginners would not have an ISP programmer so milage may vary.
1) Not sure. It looks like the light sensor is currently this one: http://www.sparkfun.com/products/8348
2) The original Scratch board was designed to work with a mono plug (TRS). When connecting the mono plug to a stereo jack, the sleeve and ring will be shorted.
You’re right that the schematic looks strange. I would expect the sleeve and ring to be connected, not the tip and sleeve. I have seen come across some Eagle libraries that have these backwards (or maybe they are for a different part with a different pin-out) and it is possible that this is what happened here.
The best thing would be to get one in your hands to complete your evaluation.

It’s not ready for public release. But if you email info at modk.it we can get you a copy of the Modkit Widget with Scratch integration.
There is an LCD example in the above downloads that you can use with the Arduino editor. There are also many LCD tutorials on the web if you want to do something different.
For the motors, you can follow this tutorial: http://www.sparkfun.com/tutorials/195. The Modkit MotoProto shield is connected to different pins than the ArduMoto so you will have to swap out the following lines:
int pwm_a = 3; //PWM control for motor outputs 1 and 2 is on digital pin 10
int pwm_b = 5; //PWM control for motor outputs 3 and 4 is on digital pin 11
int dir_a = 2; //direction control for motor outputs 1 and 2 is on digital pin 12
int dir_b = 4; //direction control for motor outputs 3 and 4 is on digital pin 13
There are no pde files since these were not designed to be programmed from the Arduino environment. If you want something similar that is Arduino compatible, you should check out the Modkit MotoProto Shield. It can be programmed in Arduino, Modkit, and soon Scratch as well.
Yes this will work with Scratch.
Why it looks different requires a little history. The Scratch Sensor Board was originally designed (with others including Robbie Berg) as part of Amon Millner’s master’s thesis work in the MIT Media Lab’s Lifelong Kindergarten Group (creators of the Scratch project). These were originally produced with the help of the Playful Invention Company (makers of PICO Cricket). The first few thousand were sold for cost and shipped from Amon’s desk at the Media Lab. This was unsustainable so the Playful Invention Company started selling them from their site. They have finally now found a permanent home at Sparkfun with a brand new red makeover.
News - Meet the Minibloq

I think the more options for getting kids involved in programming the better. It is then up to the parent or teacher to decide which is the best way to introduce things.
If programming was like riding a bike, I see the Minibloq environment as the “big wheels” approach (google: big wheels if unfamiliar). Hand it over with no guidance and she can play around and figure out how to make it go. This can be a wonderful approach.
Modkit’s blocks are like training wheels. Just an add on to the actual bike (C-code in Modkit’s case). With a little guidance the kid can get going quickly. The training wheels can be taken off at any time (switch to code view), but in most cases they are taken off when they get in the way.
Teaching text code may require a lot of hand-holding just like it would take to teach a kid to ride a bike without training wheels. If you have the time (and programming experience) to hold handlebars, this is just as valid as the other approaches.
No public wish lists :(
