I found a Smith Corona electric typewriter with everything intact yesterday, and he (I named him Eniac, by the way) took me through a demonstration of his skills. I love it when electronics are anthropomorphized and use terms like "me" and "I". Makes...
This weekend I managed to complete the single-minutes stage of the clock. After testing the flip-flop's and building the decoder I could finally connect everything together. The completed seven segment display has been sitting on my bench for months,...
I started printing the case yesterday and because it was almost 10h print, it should end in about 3 in the morning. Everything was going smoothly until midnight, when really bad cry of motors wake me up. The filament unrolled from spoon and get tangled...
Jan 15th: Project costs is something I am always trying to always reduce. Currently I have not found UL1015 wire in short lengths and only in 100' spools. Also having wires in different colors always make wiring the project easier is not a requirement....
Found some time this evening to hook up the Mega-One-8-One for testing. The Mega-One-8-One is a gate level accurate replicate of the classic 74181 Arithmetic-Logic Unit(ALU) for educational purposes. With the exception of one LED not being soldered...
The redesigned PCB came in today!Quickly assembled it and everything seems to be in working order.I will do some more thorough testing, but if everything checks out, this will be the PCB used for the first production run of DIY kits. In the mean...
Last weekend I have been testing what it's seems to be the first fully working prototype and fixing some bugs. Now SAMI is alive and fully capable of what I promise. In the next weeks I am going to do more test and after I have confirmed everything is...
I don't think there's anything more I can add, so I've started double-checking the connections and passive component values to make sure everything's right. It's good that I did, too; there were a few misplaced connections, and I'd especially screwed...
Two things: I've improved the speed and size of the Display library by switching to TinyWireM instead of SoftwareWire. It's just a much smaller library. Instead of 40% of your code being the display library, it's now only like 25% or something.I...
To be able to control the laser dot I need to create a drive mechanic that would fit the lamp hole of a earth globe. My 300mm earth globe have a 38mm hole in the bottom that everything need to fit through. I started with making a CAD model of what space...
Log no.1: Open Light Switch V1.2 Prototype What I've done? I received the V1.2 PCB, soldered everything, and tested the circuit. Images: The Assembled PCB This might be the worst quality you've ever seen for a PCB Results: Well, everything worked...
The code is coming along nicely! Everything but the Ping sensor stuff is basically done! It should be complete by beginning of next week! Talk about cutting it close! The box should also be done by early next week. Then...
As each piece of the electronics were tested individually, it was finally time to mount everything in the electronics bay. The IMU was mounted in the front so that it picks up even the smallest changes in rocket orientation. The rocket electronics went...
Finally finished all of the testing and development.Aside from a hick-up caused by an incorrect Eagle footprint everything tested as designed.Launched a Goldilocks Analogue - Kickstarter Project to encourage others to dive into the audio and analogue...
A decent amount of craft and prototyping,hacking went to fabricating square matrix of LEDsfirmly attached to massive passive planar square heatsink.Two hacked boost power supplies are tuned,CC power supply frame-heatsink construction under way.all savings...
