Every one of these first gen timelapsers was a labor of love, taking countless hours to complete. They were deployed by the dozens. The alarm clock buzzer is wired to an optoisolator which lets the tiny current activate an input to the ATOM microcontroller. The chip turns on a relay to turn off the alarm and reset for the next day then another relay shorts across the cameras power switch, it waits for powerup then another relay shorts across the shutter button contacts. After another short delay, the cam power relay turns it off to wait for the alarm again
This is the model R/C tank I am designing on a gearbox + Tracks & wheels from Tamiya. The radio is Hitec and two receiver servo outputs feed my microcontroller-based Pulse Position Modulation output into Pulse Width Modulated power output to the two motors.

Lissajous figures are interesting curves that occur in systems where oscillation happens in more than one direction, for example when a pendulum hanging from a string moves in the plane.
These pictures are from an easy persistence of vision approach to playing with Lissajous figures. Read more about this project here.
ESP32-S3 TFT Feather knockoff. Bought this one from AliExpress. Running CircuitPython and wanted to see what how showing an actual photo looked. In person it looked better than shown here and looked pretty good for a 1.14" 240x135 screen.

Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, today announced its first instrumentation amplifier, the MCP6N11. The new instrumentation amp features Microchip’s unique mCal technology, which is an on-chip calibration circuit that enables low initial offset voltage and a means to control offset drift, which results in higher accuracy across time and temperature. The MCP6N11’s low-power CMOS process technology enables low power, while providing a gain bandwidth product of 500 kHz, and it features a hardware shutdown pin for even more power savings. The device’s low, 1.8V operation allows two 1.5V batteries to be drained beyond typical use, and its rail-to-rail input and output operation enables full-range use, even in low-supply conditions.
Talks and performances by people doing strange things with electricity
Fri 23 March 2012, 6.30-10pm with interval at the Showroom Cinema, Sheffield.
Dorkbot is a meeting of people interested in electric/electronic art in the broadest sense; robotics, kinetic art, microcontrollers, interactive art, algorithmic music, net.art... The only real conditions are that it is a bit strange and involves electricity in some way. It is really defined by whoever turns up, be it engineers who want to be artists, artists who want to be engineers, or the otherwise confused.
This MEGADORK event features a cabaret of talks and performances from among the UK's dorkiest, to entertain and amaze:
Paul Granjon - A strange performance from the world renowned self-styled robot artist.
Patrick Tresset - Talks about his drawing robot Paul (on show as part of the Alan Turing: Intuition and Ingenuity exhibition).
Daniel Jones and James Bulley - talking about generating live music from patterns of weather.
www.variable4.org.uk/about/intro
Sarah and Jenny Angliss - playing robot music from past futures.

The first solar timelapser on four inch PVC pipe. There is four feet of that pipe buried in the ground. That solar panel is nowhere near big enough
Have you ever thought that most of our perception about the robot is based on the Hollywood movie! The well-known 3CPO and R2D2 from Star Wars until the little cute garbage compacting robot named WALL-E; all of these machines are example of our dreams or should I say our quest to what we all think about the robot should be. Although the robot that we are going to build here is still far away from the technologies shown on those movies but at least it will give you an introductory to the robotics world. for more information please visit www.ermicro.com/blog/?p=983
First 32-bit- microcontroller-based, open-source development platform that is 100% Arduino compatible.
Yay once more, for I have installed the microcontroller in the clock's mainboard, connected it to the driver / tubes board and successfully burned the controller using the Development Environment of Kings.
It's still not quite a clock; the program it's running just steps the display through all 24 hours at roughly half a second per minute. Hooking up the clock chip is the next step.
Update 9/4/07: OK, now it's a clock. The controller and the clock chip chatter like old buddies. The battery backup works, though I had to put a penny in the battery holder along with the battery because I goofed and bought a 2-battery holder and only use one. I chose a 1925 wheat-back penny I found while clearing enough space in my very cluttered office to make room for the D. E. o'Kings, and it conducts electricity as though mad, apparently. You can set the time and it seems to be rock-solid, though I haven't tested it over more than a few hours yet. All that remain are a couple of finishing touches to the software, and the guts are done done daddy done done.
Next up: The enclosure! Time to go from crudely-sawn wood and hot glue gun glue to a nice wooden Art Decoey thing made of sightly (but not endangered) hardwoods. May take awhile, because I'm even more of a beginner with woodwork than with electronics - but I'm signing up for a woodworking evening class at the local high school so I can get access to the big power tools that won't fit in my basement or budget.
As the electronics hobbyist one of knowledge that we have to be familiar with is how to make our own printed circuit board (PCB).

A pwb course exercise. I had to lay out a circuit in Orcad, I wanted to try a certain clock generator and I've been thinking of putting some of the 8515's on a board. So I threw something together. Two sided board, plated vias, milled with some machine. Kind of tricky to solder. Larger pads and holes would have been welcome in hindsight.
