I’ve looked and been unsuccessful in finding household nightlights that meet my criteria: auto on/off dimmable 1800K CCT decent CRI uniform illumination no flickering power efficient The closest I found was this nightlight. I like everything about it except the 3000K CCT. I believe it’s a bit too cool for a nightlight. I ended up swapping the 3000K LEDs for 2200K LEDs. I would have preferred 1800K, but was unable to source them on Digikey. ...
This is a custom bracket for holding a pair of prescription lenses inside a scuba dive mask. The goggles here are the Atomic Frameless 2. These goggles are great quality, have a wide field-of view, and have enough clearance to fit a pair of glasses inside. I designed the bracket in Autodesk Inventor and printed it on a 3D printer. You can find my design files on Thingiverse here. If you want to customize this bracket to fit your specific glasses and mask, you can get a free copy of Autodesk Fusion 360 here. ...
This how-to is for exporting a part from Autodesk Inventor and importing to Ultimaker Cura for 3D Printing. Once you export a STL file, it can be used with programs other than Cura. Step 1 Open your part in Autodesk Inventor Step 2 Go to File->Export->CAD Format Step 3 A “Save As” box should appear. Click “Options” ...
This how-to is for correcting axis orientations or rotation issues when exporting a file from Inventor to Cura. improper orientation causes this issue in Cura Step 1 Open Inventor. Export as an STL and import into Cura (how to export a STL here) Do not rotate the model in Cura Step 2 Rotate your view in Inventor to match the Cura model. This will make the next steps more intuitive. ...
This ORS (oral rehydration solution) is 10 times cheaper than Pedialyte and contains a wider array of electrolytes. Gatorade, in comparison, is a low electrolyte, high sugar mix and has nothing on this ORS besides marketing. I wanted something to mute hangovers or to drink after a long day of sweating. But I don’t want to spend $4 on Pedialyte or drink a gallon of sugary Gatorade. This ORS closely follows the nutritional profile of Pedialyte. The ingredients are similar too, excluding Pedialyte’s additives to improve solubility and shelf life. As a powder, it is more convenient. Compared to a $4 bottle of Pedialyte, 1 liter of this ORS costs about 41 cents! ...
This is a conversion of a convection toaster oven into a SMD reflow oven. I took a standard toaster oven then added insulation, ControlLeo2 controller, temperature sensor, cooling fan, and a front panel. It has excellent thermal properties and follows a reflow profile well. I bought the ControlLeo2for the reflow controller. It features PID control and is overall good. Still has shortcomings. I had to heavily modify it to make it fit in the front panel. A different LCD (8×2 or 8×4) and a new PCB layout would make this board slim enough to fit. Additionally, I had some issues with LCD corruption and had to modify the software. I am also disappointed with the lack of PID control for the cooling fan. ...
This guide is for removing keys off a Lenovo ThinkPad T450s and should also work for the T430, T440, T450, and T460. There are fragile retaining clips on the underside of each key. Repetitive removal will surely break them. Once the clip breaks, it must be replaced. Key Removal Wedge your finger underneath the upper left and pull directly up until you hear a single click. ...
I use Neewer’s hot shoe LED lights for a variety of purposes - photography, video, and scanning negatives. The CN-160 is incredibly bright and dimmable. Unfortunately, it is designed to take 6xAA batteries. Or, if you have the right camera, you can attach your camera’s lithium battery to it. I don’t like either option. I use 18650 batteries for my headlight and I want to use them here. I added a voltage monitor so I didn’t accidentally drain the batteries. I added a DC barrel jack for connecting to a wall adapter. This was for scanning thousands of negatives - I needed full brightness for many hours. ...
This how-to concerns making an adapter to hold a flashlight on a standard gopro mount. It allows you to mount a flashlight to a helmet or anywhere else you’d need a securely mounted flashlight. There are a few 3D-printed gopro flashlight holders on thingiverse.com, but they all seem to be either bulky or fragile and all require a screwdriver for installation and removal. My design uses a gopro mount, is secure, and forgiving to abuse. It uses velcro to accommodate many different flashlight and makes removing the flashlight very quick. ...
Most dedicated film scanners don’t scan negatives as well as your camera. If you spend anywhere between $50-$200, you’ll first spend a few hours reading polarized Amazon reviews and end up with a cheap plastic scanner with a little sensor and quite average resolution. For better quality you have to jump up to $500+ to get a professional quality scanner. They are usually quite slow and designed for scanning just a few pictures then bringing them to Photoshop to touch them up. ...
