2018-12 FDA performace testing
14-hour runs on FDA S/N 16 from Aivon LTD now in Aders’ blog: http://www.anderswallin.net/2018/11/distribution-amp-s-n-16/ The conclusion is that it is quite hard to measure the performance of the amplifier, because the instrument noise-floor usually dominates!

2018-12 Narrow version of FDA-board
Here’s a modification of the FDA PCB design to fit in an enclosure that takes a 160mm wide board: http://www.anderswallin.net/2018/12/compact-frequency-distribution-amplifier/ design-files to be added here.
Compact Universal Timing Endpoint Based on White Rabbit with Dual Ports Cute-WR-DP
Cute-WR-DP Cascade mode ready for release
The cascade mode can support daisy chain connections of multiple dual-port WR node like the Cute-WR-DP which can greatly simplify certain applications. The released firmware can easily be ported to other WR nodes which has multiple SFP ports.
WRS Fan-less hardware
Over 100 WRS-FL produced!
Over 100 WRS-FL has been produced, many of them will be installed at Daocheng, The LHAASO site.
RF Multiplexer 8ch 1GHz
2018.11 design update
migrate to kicad5 symbols and footprints. only minor changes to pcb-design. new PDF hardcopies of 2018.11 PCB, SCH, and BOM.
Radiation Tolerant LED Luminaire
New schematics added
For those who can’t or do not wish to download LTSpice to review the project schematics and simulations, we have now made available all 3 design variants in PDF form, so that they can be more easily viewed on any computer.
White Rabbit
15-11-2018: EC Webinar 5 Dec: OSHW for science & beyond...
Webinar: How to foster open source hardware for science and beyond: the WR project Javier Serrano (CERN) and the Open Science Monitor Consortium will share the lessons learnt from White Rabbit case and discuss on how to foster open source scientific hardware in Europe.

2018 September: Arduino MKR Zero controller and revised PCB
Revised PCB with 10-pin IDC/ribbon-cable for powersupplies and SPI-control. Control by Arduino MKR Zero with Ethernet shield. This arduino will be easier to integrate into a 1U enclosure, and removing the voltage-regulators for the mux-PCB simplifies the board.
