Module Interest


#1

I have a little extra laying around to invest in Skewworks and I wanted to see what kind of module interest there is out there.

The GPS units are almost fully populated (we’re expecting China to deliver the last piece within a week or so).

The 6 button module is cheap, fast and easy to produce if there’s interest. I could also do a 4 button module which would be great for direction pads or an A/B/C/D game pad.

We’ve also got a I-Socket 1-to-3 hub (you can actually connect whatever you like to it).

Or perhaps there’s another module you’d really like to see run? (We have a LiPo design but I’m not sure a decent run is within reach for the budget).

That would be nice but I don’t think that’s in the cards for this run. :wink:

NFC Module


#4

Some interests :

  • A keypad Module (0-9 + * AND # at least)
  • A GSM-3G/4G SIM Module
  • As Ianlee an NFC Module

I +1’d ian’s NFC idea. Plenty of good OSHW hardware designs available to start from, but not much in the way of full featured software drivers. For example, Adafruit has a great board with a well tuned antenna (https://www.adafruit.com/products/364) based on the PN532 IC, but only implemented the barest of RFID functionality in code. There is an open source effort at http://open-nfc.org/wp/ that supports a lot of the bells and whistles on this chip…

I"m also keen on a LiPo module. Something I could plug a good sized RC battery into that also has a charging circuit (for solar :). I do realize that would be more than trivial and fairly pricey, though.


#6

YES defiantly.

#7

I was going to +1 earlier on the LiPo battery module, but decided I wouldn’t. Personally, LiPo is not what I need, but a battery based solution is.

But what I have been thinking about is probably a non-Gadgeteer solution (in fact it may be a dumb uC-less module), but similar to @ Ransomhall’s solar comments. I need an autonomous solar powered battery charge/discharge module to run some LEDs at night and charge during the day. I think I would prefer a more tolerant battery type (thinking 18650 Li-Ion?). Hmm, time to look at @ ladyada’s solar charger design again in more detail I think…


#8

Looks like maybe I need to look into NFC.

I’m also looking into created an all-in-one board based on the Cerb40 for educational use. OLED, Buttons, SD, BatteryPack, RTC battery, possibly minimal sound and mating connectors to link them together.


#9

Another vote the educational board.


#10

whats about a Ultrasound or infrared rangefinders.
Maybe with a DaisyLink so its easyer to connetct several Modules.


#11

OK, here’s what I’m sending off for the Educational Device. Let me know if you see anything needs adding/changed. I’m not putting in USB host just because I need to keep the references LOW to have enough RAM to keep a 128x128 image + font.

#12

Here’s a look at the design.

About 6" x 3.2"


#13

16bit, 16 inputs ADC


#14

not living in the US I don’t know much about this, but there is a defacto standard education board, the BOE and boebot etc, that parallax have created/expanded (don’t know the history), which is also an evolution of the device Fez Mini got its footprint from. So while I don’t want to dissuade you, it might be worth thinking about if you can get coexistence / compatibility with that format?


#15

Yes, I really love an updated version of th FEZ mini for my TV remote LCD touchscreen i build some time ago. Now the Cerb processor is much smaller i think an accu connection and an onboard charger would be really cool to have. Sadly im not that advanced as you guys are otherwise i already made one myself.


#16

I’m not super concerned with BOE. :slight_smile:

I may look at doing a similar footprint in the future but for now this is roughly the design I’ll be going with.


#17

Yeah, the concern would be if you try to out-place them and there’s a raft of equipment already held by schools, the last thing they will want is to replace it - as long as you’re cool with that ! :slight_smile:


#18

Educational and hobby doesn’t have to mean in every school. I know my kids schools don’t have any equipment at all. And my board would be less that comparable. Plus mine will have some support no one else can claim. :wink:

Yeah I took teasing lessons from Gus.
