Setting up sendmail for home office / workshop mail relaying

[Article updated 22 Oct, 2016]

Recently, our workshop completed some OS and software upgrades. Here we are posting some field notes on setting up an internal mail relay server, which is one of many long overdue tasks. Hopefully this will benefit anyone working on similar projects.

Why mail relay?

Here in our shop, besides regular desktop workstations which are Microsoft Outlook and Mozilla Thunderbird based, we also have quite a few “low-tech” network devices that communicate using SMTP. These devices such as UPS, Multi-Function Printers, Nagios and Security Cameras all use SMTP for alert and notifications.

Still flying Nitro? Time to Re-build your starter

Extreme Makeover of the Dynatron starter

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?

Need aluminum for a project in a rush?

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.

Prologue

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.
