Wake up in the middle of the night because you re too hot? Don t want to spend $3000 one one of these? Not cool with a corporation controlling your sleep with a mandatory subscription? Don t care for swamp coolers? Some other thing? This might be what you need! This project is a refrigerated mattress pad [ ]
Here s a new project I m working on a RC wheelbarrow on tracks. It s exactly what you would expect. I took some time to model all of the different parts in Solidworks the motors, tracks, casters, wheelbarrow, actuators, etc. then I arranged them in an assembly and designed the chassis that I would [ ]
Slowmo shot of cutting a keyway on a CNC EDM. Definitely overkill, but easier than broaching the keyways on a taper for these sprockets: These are for a remote control wheelbarrow project I ll share later. For setup the sprocket was put in a v-block and tilted so the taper angle was vertical. The graphite electrode [ ]
This is a batch of cider made with just blackberries, raspberries, and blueberries. The image was generated by stable diffusion. 9/10 Started with: 3 lb blueberries 6 lb blackberries 5 lb raspberries 6.5 lb sugar Water to reach 5 gallons Starting gravity: 1.060 9/11 Added yeast: Safale S-04 9/16 Fermentation was pretty slow, removed the [ ]
Unlike some other microcontrollers, the RP2040 doesn t have any EEPROM onboard. On something like the ATmega328P for example, it is easy to save the value of a variable to the EEPROM so that you can read it back on the next boot; this is handy for remembering a user setting or recalling the last state [ ]
This is another smaller batch of golden plum wine. The main difference between this and the previous one is that the skins were removed before fermentation and it was only sweetened about half as much. Fun fact: the plum on the label was drawn with stable diffusion. 8/18 Started with 16 pounds of plum goop. [ ]
This is a sort of journal for some batches of homebrew, there s a link on the label to this page hopefully just in case it turned out to be good and I want to repeat it. Compared to the following batch, leaving the plum skins on during the fermentation made it more difficult to [ ]
In this post I ll share my implementation (so far) of an approach to find the distance and direction of a beacon, with an end goal of building a human following robot. It s not an original idea here is an earlier project by Ben Heck and Jesse Robinson that does the same thing. Check the [ ]
I just scooped up a Vizy Camera for a for a robot project I have in progress. Essentially this is a Raspberry Pi 4 with an Arducam camera and a custom power board in a bespoke case. Check the reviews on tomshardware and hackaday for a little more info. My first impressions are mostly positive [ ]
This is a quick and dirty thing to get solder fumes out of my face. Uses a 120mm computer case fan, a sheet of carbon filter material from Amazon, and held together in a sandwich by zip ties. (Filter is between the two parts with the tie fighter looking grid)
