Sometimes you have a novel idea but you don’t have the resources to manufacture it for real. Thanks to home 3D printing, you can at least make a version of your invention for yourself. In this video, I recreate a uni project from twenty years earlier, the Lumimate mechanic’s light.
The aim of the video is to showcase my design and problem solving process, and to inspire you to manufacture your own ideas. However, if you do want to make your own Lumimate, everything you need is on Printables: www.printables.com/model/5015...

Very nice project. One suggestion I would have is to avoid running LEDs in parallel like you have. They won't share current evenly and, worse, can thermally runaway. The LED forward voltage decreases with higher temperature, which will cause one of your LEDs to carry more current than the others and self heat itself even more. This process continues until the LED fuses, then another one will runaway, etc.

After spending 3 months on a LED DLP projector backlight (for automotive HUD application) i cringe a little when i see something like this. BUT if it get's the result he wants and if it helps him have the project finished i think it is the best thing to do :) I sometimes drop hobby projects because i know the effort/time needed to get some little electronic thing right and i just don't continue - and this is worse than having something half assed in a finished project:)

Or just do it the decent way: - Some ultra efficient, high power leds. That are 10 times brighter than those he uses now. - A led driver, that supports dimming trough a sense resistor. - A multi position switch, in order to set different brightness's. The resistor before the led's, is just inefficient and cheap...

Very impressive video. Great example of the engineering process. Some alternative suggestions for your design to think about: 1) 9:20 - Change the holes for the LEDs to a hole and a slot (not necessary here, but something to always remember as an option). Two holes over-constrain the part, don't allow from the parts to "breathe" due to temperature and humidity cycling, and warp more easily during molding. 2) 8:16 - Instead of always going for a "snug" profile fit, make the opening 1.5mm larger around and add standoff ribs, bumps or cones strategically. Especially for prototype parts, they are easy to shave down to get to the right fit. This is great to dial in alignment issues too. Another example of over-constraining the part. Please remember your datum rules: 3-2-1. The A datum is 3 contact points (surface), B datum is 2 contact points (line), C datum is 1 contact point. All parts that fit together should follow this rule (exceptions for very large or flexible parts). 3) Would this have been a good example to add a textured finish onto the part? You will be gripping it with greasy hands often. Maybe? Again, good job on your design. 👍

Overall, the design works well! Having the 3 'feet' to help with uneven surfaces is a good design choice! Just some suggestions from a hobbyist mechanic and aerospace engineer: If possible, moving the switch from under the base to the back of the lamp head would be more convenient, using a COB led array would provide more light. A row of 4 or 5 charging LED indicators progressively showing battery charge state would be a nice addition. Adding rubber seals between the joining seams would help to keep oil out from oily hands, etc.

One potential change is to connect the batteries in series with a BMS and then use a buck regulator to drive the LED's. The efficiency gain should increase the run time of the batteries as well as prevent over discharge.

I designed a torch many years ago. It was a hand torch which exploited persistence of vision to prolong battery life and mimicked motion you tend to make when negotiating dark paths (sweeping side to side or making circles and ellipses). The design got no further, due to cut backs I was told the light at the end of the tunnel was to be switched off.

First thoughts are: I would use FDM printing with a more impact resistant material (for the base, at least. I find resin prints are brittle and are not UV tolerant). If you put the magnets nearer to the surface you want to attach to, they don't need to be as big. Finally, I think a LiPo flat cell would probably allow a more streamlined design.

On top of the suggestions about how you wired the LEDs, I would think you'd also maybe prefer putting them at a different angle, like the Ikea Jansjo. Your design has you constantly turning the head of the lamp 90 degrees to where you want it, while a lamp head like the Jansjo has you pointing at the goal. ... also, I'm just realizing that they now sell the Jansjo as a USB lamp. Mine are on clamps attached to machines and desks, but plugged into the wall via a 4V 0.75A wall wart.

When making holes for screws use a square instead. The material the tread takes away gets pushed into the corners of the square and it is less likely to crack. - a great video, it’s nice you came back to the design to make it a reality, it shows how far you’ve came

I imagine there's some reason you wanted to use your resin printer (mine's certainly sat unused for a while...) so I won't critique that over the more obvious choice of ABS, but it's worth noting the absurd cost of the magnets is due to their orientation here. There's a reason commercial versions of this use exposed disc magnets, just a few mm thick; something like 20mmx4mm would probably even be overkill if they're actually pointed the right way.

Michael, how much of the electronics knowledge did you formally gain in your Industrial design training? I'm a Microelectronic engineer with specialist background in Electromagnetic Environmental Effects and find I'm having to revisit a lot of basic knowledge for projects like this. I'm now medically retired and considering formal education to learn more CAD/CAM ... I'm not sure where best to get engaged in it though. Do you have any recommendations? I trust you would have some genuine insights as a Teacher.

@TeachingTech Жыл бұрын

My meagre electronics knowledge came as a hobbyist, there was nothing including in my design degree. At uni we focused on the design process, project management, CAD, presentation with software like Photoshop and Illustrator, all with a big focus on designing for manufacturing (primarily injection molding). A lot of universities and TAFEs in Aus now have 100% online courses. I did industrial design face o face but later when I added my teaching degree as a post grad, it was all online apart from one exam. For your needs, it depends on where you want to teach and the academic requirements they have. So maybe look at where you could teach CAD, and speak to them about what qualifications you would need to be employed. Best of luck!
