The backlight can stay on permanently if used with the power adaptor which is INCLUDED. *the digital display may vary in contrast depending on room lighting. Negative LCD display with 12 hour / 24 hour setting option.Use on a dark wall or ceiling within 1-4 metres. There is a rotate and tilt option to ensure the projection is oriented correctly. Projection Feature: The continuous projection feature can ONLY be activated when the power adapter is used.Snooze / backlight function (Snooze interval is 5 minutes).esp32beans liked Roktrack - Pylon Guided Mower.( KD9VFU ) has added Joshua Ramjit as a contributor to SDR dock 1.0. deftcoyote has added a new log for Custom Intellivision Controller.Tejeev liked Bi-Generator vertical wind turbine.Michael Gardi has updated the project titled A Tile Based MacroPad.BastelBaus has updated the log for Simple 6D Space Mouse.FulanoDetail has updated the log for DIY Mech/Exoskeleton suit.Kirby on Getting Geared Up For Home Powder Coating.Anonymous on Electrostatic Generator Project Starts With Molten Sulfur.Phil Barrett on Getting Geared Up For Home Powder Coating.Steven-X on Hair-Raising Tales Of Electrostatic Generators.reg on Reviving An Old Lime-E Beta Rideshare E-Bicycle.Conor Stewart on Hackaday Prize 2023: A 3D Printed Vertical Wind Turbine.PWalsh on Getting Geared Up For Home Powder Coating.Lee on Powder Your Prints For Baby-Smoothness.The cost of the uC is irrellevant compared to the rest of the hardware / time.īutton, Button, Who’s Got The (Pico) Button? 25 Comments It is not a commercial project of which a million units are made. In post #32 there is a clear expanation of how it works, together with a bunch of screenshots from Sigrok / Pulseview.Ī hobbyist certainly will not outgrow the STM32F103 family quickly, and small projects like this are perfect for getting familiar with it. This results in a waste of time and frustration, and all for maybe trying to shave EUR 0.50 off of the BOM.Īnd all the while they do not have extra pins for debugging purposes.Įxtra I/O pins for debugging with a Logic Analsyer is an extremely helpfull while searching for software bugs. A month later the few KB of Ram or Flash they have is filled and they need to switch uC for their project. ![]() I also see lots of beginners on avrfreaks (for example) who start with a small 8pin tiny AVR and then have to add shift registers or I/O expanders because they run out of pins. Posted in Arduino Hacks, LED Hacks Tagged clock, lcd, led Post navigation I’m not sure if you would want to attach your expensive camera lenses to a home-made projector like this, but it’s good to have the option if you have a dead E-mount lens that you were going to tear apart for parts anyway. has released all of the files he created for the project, including a number of options for the case that can use C-mount and Sony E-mount lenses. His project has room to grow as well: it runs from an Arduino compatible STM32 that could handle many things other than showing the time if you were inclined to expand the project further. ![]() He does a nice job of laying out his thinking in this design, showing how he calculated the projection path and made other decisions. Cheap is the order of the day here, and succeeded admirably, creating a design that can be made with a couple of cheap PCBs, a 3D printer and the other parts mentioned above. There are plenty of cheap projection clocks available, but as points out in this project, where’s the fun in just buying something? He set out to build a cheap projection clock using a small LCD screen, a cheap LED backlight, and a cheap lens.
