New series of Friwo FOX mains adapters meets the most stringent energy regulations already now and at the same time it´s more compact than its predecessors.
DoE 2016 is a known term naming stringent regulations established by DoE (department of energy USA) valid from year 2016. Among other things it brings a requirement for a standby power consumption of small adapters to be below 0.1W. In Europe we have here a limit of 0.5W for majority of small adapters, but even here can be expected toughening in the nearest years.
That´s why German company Friwo as a long-term long-term OEM producer of power supplies and adapters comes with a new line of mains adapters named “FOX”. Besides high efficiency, these power supplies are also extraordinarily compact. Already recent series MPP and GPP are very compact, but FOX is a “step further”, as also illustrated on attached picture. System of exchangeable primary and secondary adapters (connectors) enables to use the same power supply for various applications and in various countries.
Even the FOX series meets various international requirements and obtained many approvals. a medical version will be also available soon. The FOX series is a novelty – 12W types are available upon order. Gradually also other types – FOX 18, FOX 30 a FOX 6 will be produced.
FOX series, as the only type on the market meets criteria for IP42 protection – with selected primary adapters (connectors).

Raj from Embedded Lab has designed this breadboard friendly adapter for rapid prototyping with the ESP8266 serial-to-wifi module. It receives a ESP-01 model ESP8266 transceiver through a 2×4 female header and provides easy access to those pins through two single row headers that are breadboard friendly.

My lifetime project: building an 8-bit computer using Z80 CPU. This week I had a bad flu and could not do anything useful so I decided to dig up my old plans for this project. I first re-designed many things, like power, CPU-board, IO-board and so on (my old plans were around 10 to 15 years old). After some thought I realized: When I get even the CPU-board working, I want to display some stuff! So why not build the display adapter first. Plus I planned to build the adapter in a way that it can be used separately from the computer itself. Easy thing to start with.

One, tiny Dart. Power for all your devices. Perfect for your mobile lifestyle.
The Dart is the world’s smallest, lightest laptop adapter. At a powerful 65W it is a perfect complement to today’s thin, lightweight, portable laptops. It fits in a pocket and is designed with a USB port and single outlet profile to make it easy for you to stay charged up when you’re on the road. We hope you are as excited about the Dart as we are and looking forward to finally carrying just one, tiny Dart to charge all your electronics. Join our campaign and never be stuck powerless again!

I’ve been thinking about making a temperature logger for my room and my computer, I set on using DS18S20 sensors from Maxim because they’re common, cheap and overally pretty ideal. My computer is so new that it does not have a serial port (not 100% sure, I think there might be a pinheader on the motherboard with serial port connections) so I have to use USB for interfacing. Next thing I had to do was to make an USB to 1-wire adapter so I could attach the sensors to my computer.
I browsed around for a while and set on using the DS2490 USB-to-1-wire adapter chip because the circuit for it looked pretty simple. I modded the component values a bit from the ones on the original schematic from Maxim to ones I had in hand. I used 0805 sized SMD components because I have those in store.

scasagrande shared his GPIBUSB Adapter rev3 in the dangerousprototypes’s project log forum:
This past weekend I finally finished up the third major revision of my GPIBUSB adapter board. Major hardware changes include swapping the pull-up resistors for the proper GPIB line drivers, as well as swapping the FT232RL for the newer FT230X. There is a number of software improvements from improved reliability to additional commands.

Last year I bought a Canon PowerShot SX200 on ebay. I wanted to play a bit with CHDK, the Canon Hack Development Kit to make some timelapse things. Problem was, the battery would hold only up for 2 hours or so. Even worse, the camera has no power jack to attach a power supply. The solution is to buy a battery dummy that has a jack on its back. That costs like 30 euros!

nneth Finnegan has been working on thermocouple adapter called SerialCouple – [via]
The SerialCouple line of boards are simple, easy to use single-channel thermocouple adapters, meant to be an interface between a thermocouple and a computer or other embedded system. Shown in the pictures are the model one boards, which are meant to be plugged into FTDI-like USB-to-Serial adapters, but a second model based on RS-232 is in the works.

MickM built flat cable to header converter adapters : [via]
I was using some character LCD displays and realised that the cables were impossible to plug into the displays that I actually had. My PCB was single row of 16, the LCD was 2×7, no backlight. So I made an adapter for it.
