Few hours fiddling with code this afternoon.Have dropped brightness to 1/32 of full power! Doesn't leave a lot of room for going dimmer.Deciding how to actually display the time is quite tricky in itself. I have an inner ring with 12 leds and outer with...
So just after presidents day we came back into the office and found that the FLED was dead! Turned it on and nothing happened. After eliminating the ATX PSU from the equation it became clear we would need to pull the display down and open it up to find...
The boards arrived on Saturday. I finally had time to sit down Monday night and begin populating one. Full disclosure, this was my first time doing and fine pitch or SMT work. I began by doing a full electrical test on one of the boards, which it passed....
This log includes major upgrades included in the current system.Till now we had been using an older OS incompatible with RPi 3 since the display could have only worked with that image. Additionally it caused the trouble where the onboard or external...
I have had nothing but trouble getting the hub to connect and stay connected to my wireless router. I recently figured out the cause. I had placed my hub about ~5 ft from my router, and evidently that was close enough to saturate the hub's wifi radio....
As the first step of this project, kinematic model of the robot manipulator is derived. Then using the inverse kinematic equations, a given trajectory (shown by the red line) is followed while the camera (represented by the blue arrow) tracks the object....
I've been having some trouble with the first Megsy / Teensy 3.2 / Teensy Audio Board stack, and thought perhaps it would be a good time to try to solder together a 2nd Megsy board. Originally, I had intended to try to hand apply solder paste, and apply...
This is just a brief discussion of some of the choices that were made in the design of this project.First and foremost, everything was designed to be fabricated and assembled by me, "in house" so to speak. That meant that any chips had to be hand-solderable,...
Having done a bit of SMD work with this device now it's worth passing a few comments. First of all it makes an amazing amount of difference to SMD soldering in general. I find myself no longer using the magnifier because the component is securely held...
Hey all!This is another project log to update the latest developments of OWL (Just in case you forgot, we call it OWL because, well, Open Indirect Ophthalmoscope, OIO).So, since the last time I made a log, we’ve been working on--making an elegant GUI...
Around the end of October, I finished up the design of all the plastic components which would house the electronics of a 200W x-ray system. It was now time to design those electronics!Back in September, I had an idea of how I should go about doing this....
Earlier version of the device was reconsidered in terms of following aspects:• Accommodating for different refractive errors • Aesthetics • Ergonomics • Weight distribution OIO ASSEMBLY EXPLODED ASSEMBLY1. ACCOMMODATING FOR DIFFERENT REFRACTIVE ERRORS...
This project was underway before I actually was on Hackaday.io, so a quick summary of where things stand:-The PCB seems to be functional. It milled just fine and there weren't any assembly issues.-The software is at a rough prototype stage. It has a...
My strings of GE Color Effects are quite old - purchased in 2010. Evidently in the past couple of years, they have changed the lights to a style which is not hackable. The new lights have 2 wires per bulb/pixel (one in, one out), which provides...
