electroFUN LTD: Mini Heatbed for Play

We bring along a mini heatbed we have just develop for the Lewihe Play or the Printrbot Play. If you want to upgrade your mini printer to be able to print more demanding filaments such as ABS this accessory is for you.

All components are mounted on the bottom side of the board to make full use of the entire heat surface of the bed.

Thermistor: NTCS0805E3104FXT

The bed comes with a thermistor fitted and two convenient pads to solder a 2 lead cable to connect to your electronics.

Solder pads on the bottom side of the bed

2 LEDs will show your board's activity while heating. The LEDs are also mounted on the rear of the board and two small windows will show the light on your print surface.

We recommend that you don't print directly on the board and install a small glass over it.
If you like the heatbed, check it out on our on-line store.
Let's Play.

General description

AVR line

Our AVR line is an open-source Arduino-compatible project. We have thought of a line of small development boards that are fully compatible with the Arduino development environment. These boards are ideal for projects; with a small footprint but with the same performance as regular Arduinos.

The idea here is to make available the Eagle files you would need to make your own board variants and if you don't want to go through the hassle you can always order them from us.

We would also like to hear and see where these designs have gone into or any derivative work made from them. So please, keep us posted and we will share it with the community.

Licensing

While Arduino is a protected trademark, the name of our AVR line can be used freely and has an unrestricted license to use.

These boards have been inspired by the Creative-Commons 2.5 licensed Arduino reference design (please refer to the schematic file for attribution information). Boards are licensed for any use ( hobbyist, commercial, non-profit, etc.) under Creative Commons 3.0 Attribution-ShareAlike (CC BY-SA). None of the board names are registered, but we encourage you to use it in any case and provide credit to the source.

CC3.0 requires you to maintain attribution to the people before you on the schematic, board files and any derivative work you do with them. You don't need to give attribution on the physical proucts that you might make with these files, but we would appreciate it.
