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.

Gameduino connects your Arduino to a VGA monitor and speakers, so anyone who can write an Arduino sketch can create video games. It’s packed full of 8-bit game goodness: hundreds of sprites, smooth scrolling, multi-channel stereo sound.
