I've been looking for a project with a real use case for a while now, but most ideas I came up with didn't really make it far. A couple weeks ago it came to my mind that that room, which still has that makeshift lighting I installed years ago, could...
Disassembly procedures Read some of the directions in Maintenance a MTD Yard Machine Lawn Tractor and perform SECTION G STEPS #01 - #15 contained therein. Only when fully completed proceed with those steps shown below. Step 1: Remove the fuel line hose...

Here's a video of the hexapod with its newly working eyes.I used pre-existing "objects" (Propeller version of libraries) for the servo pulse generation (produced by one cog). I also used the super awesome "F32" floating point object. This object runs...
If you look at Morse code, alphabetic characters are represented by one to four units, each of which can be either a "dit" or a "dah". In traditional telegraphy with a single key, "dits" are made by short taps, and "dahs" by longer ones. ...
Nice things:The nice thing about a humidity sensor is, that only two Parameters are given out: Temperature (In fact a voltage measurement of a Silicon bandgap...)..Relative Humidity (In fact it´s a capacity which is measured physically...).But several...
I bought an Alula a few years ago. It was everything that Dream Flight said it would be, but my old damaged elbow joints did not tolerate the process of throwing the Alula repeatedly. The Alula is a DLG (discus launched glider) from DreamFlight. I bought...
Working Principle The ATtiny814 controls the electronic dummy load with its internal digital to analog converter (DAC). All of its 5 internal reference voltages are being used in order to get the maximum accuracy and resolution of the DAC. The DAC is...
I had absolutely no intention of posting this on Hackday. It's a small one-day hack (well, two-day, if you count the time waiting for the epoxy to dry) that piggybacks on all the other blinkylight fun I've had. New code? Nope; I'd already abstracted...
This tutorial uses the Hexabitz modular hardware system to create an all-in-one plant monitoring and watering system. Automate your way to happy plants 😀🪴 Hardware: Load Cell Sensor (H26R0x): H26R0x is a load cell (strain gauge) sensor...
The SuperCapacitor UPS All the UPS functions are performed by the LTC4041, which include a supercapacitor charger and a boost converter, plus all the ancillary circuits to make it a complete solution. The circuit is quite similar to the application note,...
It started when I looked at an integrated LED display in my junk^Wspares box. This came from an old 386/486 era PC and could display the clock frequency up to 99 MHz. As installed it displayed only two speeds, normal and turbo, selected by a push button...
Introduction The main idea of this project is when any human, animals or any object come in the range of PIR motion sensor, the buzzer must beep automatically. This circuit can also be implemented any where like staircase or front gate etc., and when...
I needed a way of remotely monitoring the temperature and relative humidity in a greenhouse used by my local garden club. We grow and graft tomato plants for our annual plant sale. Careful control of the T and RH is helpful to insuring the success of...
INS-1 / ИНC-1 Fortunately, these single dot tubes are still easy to find in large quantity and rather cheap. Made by Gazotron, it seems they buildup a large stock at that time. The INS-1 has the advantage to be small and produce a nice dot due...
