The Scientific Engineer presents a series of articles that show our attempt at creating popular DIY engineering tools. Every engineer or scientist loves to have a go at building that project that they have seen on Youtube or read about in an electronic hobbyist magazine. It could be the design of a SMT Reflow (Toaster) Oven or PCB Etch Tank to aid in DIY PCB projects to mention a few.

Like others we too like to "have a go".  The series of articles presented here are usually presented  in a blog style as the projects are being undertaken and results, which are sometimes surprising, are discovered and presetned.


 

  • Article Count: 3 SMT Reflow (Toaster) Oven

    Summary

    The SMT reflow (toaster) oven project introduces a series of articles that demonstrates the conversion of an off-the-shelf, commercially available, compact,  electric oven (popularly known as a toaster oven) into a surface mount technology (SMT) reflow oven. A hobbyist reflow oven is extremely useful for soldering, extremely small, surface mounted parts. It is an invaluable addition to any hobbyists collection of to-do projects! 


  • Article Count: 4 DIY PCB Etch Tank

    Summary

    0000211aThe series of articles presented in this category investigate developing hobbyist Printed Circuit Boards (PCBs) using off-the-shelf home aquarium equipment. The series investigates the effectiveness of the DIY PCB etch tank by measuring the temperature profile of a typical PCB etching process. It also demonstrated etching single and double sided FR4 PCBs.


     

  • Article Count: 1 DIY PCB Development

    Summary

    0000493The series of articles presented in this category exemplify rapidly designing  a PCB using the typical homebrew design flow. The articles will demonstrate how we have utilised the toner transfer method with a commonly available, modified laminator, a DIY PCB etch tank and standard soldering and drilling tools to rapidly develop PCBs for our projects. This method allows us to test our ideas and concepts without the PCB development consuming a large slice of our R&D budget.
    Once the concept has been successfully demonstrated, using the prototype, more professional PCB design services are employed to fabriacte our final prototype models.
