Cheers for the update.

I got stuck in the 3v to 4v dc motor google search, then trying to find the right gears and pinions!
Minefield. I did manage to build a track timer using a puck, a few ir sensors and a poorly code html page to record history and best. Ideally the track timer could be built into a car.

HI @AdamSmith, any further updates on this project ?

I was thinking about doing something similar a while back but like most of my ideas they never make it into the psychical world.

Did I miss a post about these new boards ? @Gordon whats the news ?

https://devzone.nordicsemi.com/question/63576/how-to-launch-siri-from-nrf51/ any help ?

Also https://learn.adafruit.com/ios-switch-control-using-ble/configuring-ios-switch-control .... a different way of getting the functionality you need ? possibly.

Great news for small order size, I'd imagine these forums alone will get you well past 100 units. I vote for the small pcb as per the thread :-).

Have you any example alpha/beta designs you can share ? You might get some feedback here which will help you narrow your offerings.

Photos of your programming harness @gordon ? Its seems you're further down the line getting something released ?

Can you get a commitment from these companies before getting the new boards made ?

Selling a cheaper board bundling with other stuff they provide might be appealing.

How do companies like Adafruit and Sparkfun buy from you ? To they commit to 100, 200 ? Is it sale or return ?

A very small javascript BLE board with only the basics is exactly what I've been looking for.

I'd agree self soldering something that small would be a put off for some, including me. I've already tried with a RN4020 had 75% success rate.

Surprised a third party couldn't create these at a competitive price, have you tried http://ragworm.eu/ ? Not used them myself, but seem to be all about open hardware and in the same country.

@Gordon just watched your new silk screen video (https://www.youtube.com/watch?v=OWuIbHIiJ6k
), was that a sneak preview of you next hardware release ? tiny board + nRF52832 + espruino ?

I didn't :-)

Pins for external battery

Oh wow, that is small.

The idea of using a small/basic ble esprunino in a plug an play manner would be great, BYOB - Bring Your Own Bluetooth if you like.

Also 3.7V compatible :-)

I'd love to have an "Original" espruino in the nano2 form :-).

All you need should be in this thread http://forum.espruino.com/conversations/297514/#comment13462264

Think he means this for example

Connected to device UUID: 5D9D6DC0-8162-4DF5-97F7-544733A0B978 Named: Puck.js de81

It did cross my mind, but wasn't sure how it handled analog input so thought I'd role my own. Could also of bought a Parrot controller for £40 but there's no fun in that :-)

Thought I'd share my progress on my latest project the PuckPad. Currently a breadboard project which I'll hopefully move onto a custom PCB once I've ironed out all the issues ( and found another adafruit joypad pcb available in the UK ).

The puck will read the relevant pins every 750ms ( will be 200ms outside of testing ) and update the custom BLE characteristic.

TODO

• Add second joystick
  
• Complete IOS app - pure software controller working just need to connect to the puck and get the values.
  
• Create custom PCB - adafruit have already created a single PCB file
  
• Check battery usage
  
  

I'll hopefully post back my progress in the coming weeks :)

@OwenBrotherwood https://www.seeedstudio.com/MDBT42Q-nRF52832-based-BLE-module-p-2736.html

No idea if they can have the firmware uploaded out of the box, which I think Gordon was alluding to.

@Gordon have you thought about doing a https://www.massdrop.com/ to help carry the cost burden.

Great thanks for the replies.

I'm thinking about using a couple of these https://www.adafruit.com/products/2765 to fly a parrot minidrone ( all BLE comms). Big pipe dream with lots of coding ahead.

Someone has already done alot of the hard work https://github.com/fetherston/npm-parrot-minidrone/blob/master/lib/MiniDroneBtAdapter.js

@Gordon Is there a guide available to add a bigger battery to the puck ? Looking at making a ble joypad and thinking a 2032 will soon drain.

UPDATED: think the issue is an xcode caching issue

Yesterday I was developing an IOS app that connects to the puck and was working fine. I then hit the save issues. Now my app is getting null values when querying the services characteristics. Using Ligthblue (ble app) from OSX I can read the values fine.

console output from xcode

Puck.js de81
<CBService: 0x174261d00, isPrimary = YES, UUID = 6E400001-B5A3-F393-E0A9-E50E24DCCA9E>

<CBService: 0x17407fe00, isPrimary = YES, UUID = Battery>
<CBCharacteristic: 0x1700b66e0, UUID = 2A6E, properties = 0x2, value = (null), notifying = NO>

I believe the issue started when playing with notify: true with the characteristics on the puck side of things, but with the save issue and this bug I lost track a little. So I was going to wait for 1.92 before I fully looked into the issue.

Also is there a function to list the pucks current services/characteristics ? without using external software ? something like NRF.getServices() ?

@Gordon do you have an ETA on 1.92 ? I've hit another issue which I'm hoping 1.92 fixes.
