Cable making service?

Hi all --

Does anyone know someone who can make high quality cables?

I need to make an adapter from a JST-PH 2-pin male connector to a two pin 0.1" female header connector.

To hack up something like this would be trivial, but I need them for a situation where they should look near perfect - for this I came up with:

public DelegatingCookieConfig(CookieConfig config) {
this.delegate = config;
}

BLE Nano and the nRF51822 SDK

If you've tried using the nRF51822 SDK with the BLE Nano (after following the RedBearLab guide) you may have come to a dead end.

Even the simplest examples didn't work for me. I assumed I had a dead Nano (despite the upload process seeming to work fine).

The reason turned out to be that the latest SDK versions assume you have a nRF51822 chip with 32KB of RAM rather than the 16KB that the nRF51822 on the Nano has.

James Willcox explains this in a post to the RedBearLab BLE Nano support forum.
