This page is going to be heavily in progress for the next few days. When I have time I will update with photos and more information. 8/4/2017.
Biolapse Dragonframe Interface Unit
The BDIU is the interface bridge between the Dragonframe software and the Motors on your hardware. It is a PCB with all the connections that allows you to control up to 6 small stepper motors (about 1 amp per motor max) with the Dragonframe software. This is currently at the heart of Lil’ Wayne, and will be the control for Project3 as well.
This is a great interface system for stop motion and timelapse via dragonframe. This setup will NOT be able to perform real time moves.
The BDIU consists of several main components
- Arduino Mega or clone. Generally I try to use the real deal, but sometimes the clones work just as well for 25% the cost.
- Biolapse Dragonframe Arduino Shield. This is my own custom designed PCB that make all of this super easy to connect.
- a4988 Stepper Drivers. These are used in a LOT of devices. They are great at controlling small stepper motors for this type of work. They are extremely available online, and dirt cheap.
- 12v Power supply. I recommend at least a 5amp 12v power supply. You might be able to run off battery if it has enough current output. However my uses are all in the studio so I use a power supply similar to this one on Amazon. Attach a lamp cord with a plug and you have a good AC connection to provide 12v power to the BDIU.
I would be willing to build a BDIU complete and ready for $250. I know, that is a lot more than it costs to build one, if you know my history with The Chronos Project, you might already know this but Kyle and I really got burned out on manufacturing and selling rigs and that is why we stopped. I am a busy person, the cost is what it would take to motivate me do build and ship. If it makes you feel better, I would only use real Arduino MEGA’s and would be using quality a4988’s from Polulu, not the cheap stuff on ebay. I don’t think there is anything out there where you can spend $250 and have the ability to control 6 axis with a simple USB connection to Dragonframe. Keep in mind, this is not for large systems with heavy motors.
I might be willing to part with a single PCB board if you want to do all your own soldering / assembly for less.
If you are interested, email me at Chris@Biolapse.com and we can work something out.
