Budget Surgical/Dental Headlamp for rural hospital in Bangladesh

Hello everyone. I am going to update the plans in the following month. I am aiming at a 60usd cost including batteries. I will post the plans online and I can also probably manufacture some for anyone on base cost (60 usd) if I have some time.- constantine_a_f

Isn't 120 Lumens a bit too much? I mean, I use a lower lumens led and when I accidentaly flash it on someone (thankfully not my patients, as they wear protective glasses) the are extremely annoyed by it. I can see everything with it, without burning out the detail or making it unconfortable...- constantine_a_f

I have not had the time to upgrade it with a new lower consuption led and a new power source as mentioned. I made some of them last year for 8 students here at my...- constantine_a_f

I guess (I am not an expert by any means) that a smaller f lens would allow you to put your objective lens closer (inside the focal length of the small lens). I am not sure if this is how it works. Maybe something form edmund scientific or a less expensive one from ebay. I chose the luxeon...- constantine_a_f

Very nice indeed. I suppose you are going to use a headband for your system (I would If I had the parts you managed to find). I used a carclo 9 degrees TIR because of the led I chose. I wanted a high cri, high lumens led, so I designed from inside to outside. Led first, then optics, then the...- constantine_a_f

I will use a standard usb cable with the Kensington battery pack so there is no need for a connector. But I like them so maybe I will go and ask for something like that as a b option. Thanks for the comment (euxaristw poly!!!)- constantine_a_f

I thought of connecting the driver beneath the body, but it was to bulky. I understand I am wasting power but it is ok. I also received a 350 mA, 100 Lumens 90 CRI rebel today and I will connect it as well to see what happens. I just want to use the usb battery as a trial (the micropuck will...- constantine_a_f

Hello ergotelis, I used 20 awg wire to feed the led. The driver is 1.2 m away. I emailed luxeonstar about this and they said that under 2m it is ok. I am happy with the result. I powered the led for 24 hours at 30% (where I am going to use it) and the batteries still held strong. I will...- constantine_a_f

I am waiting for the electronics to arrive. I also started practicing soldering and bought some 23 ga wire. I thinking of annodizing the body. The heat sink was pressed inside the tube, so no glue or paste was used. There are no obvious gaps. Also, what do you think about this...- constantine_a_f
