In this brand new month of January of 2012, BTF is all about reading on electronics and prototyping. Ever since our last minute power supply blog, we are hooked in electronics. During the holidays, we did some old hardware tear down (Yep, we will write a blog on Gyro tear down soon).
In this blog, we talk about a recent photography project turned into a power supply building frenzy.
New to us, the project involved some product photography work. With no experience, the team scrambled to assemble light box, staff brought in their own camera from home. While we thought we have everything ready, we noticed nowadays digital cameras do not come with AC power supply. This is absurd!
We have this starter for about 8+ years, it is a great product and the motor is running very strong. Originally converted it to NiCd cordless (15.6V) system but during years of usage, the NiCd have passed their life span and no longer take/hold charge well. Starting helicopter has becoming more and more a frustration process. Emmm… Time for a new design.
Here is the current setup.
Sullivan Dynatron S603 Super Power Starter
Custom plexiglass bracket battery holder
Multiple no-name NiCd batteries are from the nineties ( 2 x 7.2 in parallel) + (2 x 8.4 in parallel) in serial

Worth mentioning was the plexiglass mount , loved the design and fabrication. The K&S rubber battery holder mount underneath it securely. Anyhow, it is now retired. Did I mention there were a couple of times the switch blade arc welded itself together?
Home Depot, Rona and Canadian Tire store do carry some stock for emergency use. Caution, they are not cheap.
Generally speaking, they are not bare stock for milling purposes. All aluminum material are already anodized in good finish. The sticker indicates material are imported by H. Paulin & Company Limited and stock originated from China and Taiwan.
Using computer, Computer Aided Design (CAD) and modeling software; Not only we can visualize our design, we now can test, assemble and see how the parts fit before we start making them. Dramatically reduce error and bad design as a result. In this blog, we want to assist beginners by sharing our views on using these technologies, knowing the basics and transitioning your design from screen to a real part.
Following a successful Part 1, we will show you more measuring tools, followed by some milling and lathe operations.
Note that our post is written as a general intro for our hobby community, we are using our own tools from Binary Taskforce R&D lab for simplicity reason. Hope our write up can provide assistance to you in the future for your RC modeling and hobby needs. Please visit our Flickr page for larger photos.
The bench top milling machine we used in R&D is a Harbor Freight Two-Speed Variable Bench Mill/Drill Machine, purchased many years ago and went through many customization throughout the years of usage.
