An article recently published on MOONGIFT, a Japanese developer site, has showcased RasDash! The article is entirely in Japanese and Google Translate won't accept the URL as it has special characters but YANDEX does. Below are some links and a basic...
Morning update: April 13, 89 PDAfter a long night of fighting with 123D make and my 3d printer, we have our first put together. To see very bad pictures of the Main Power/Data Bus (MPDB) look at step 2 of the instructions. After getting put together,...
Mid-day update: April 20, 89 PDWhile over 75% of the internal parts are finished printing, but there is still too much to do. We have started wiring up the reactor with LEDs but it is slow going (25% done). We have not even started on the code to drive...
I haven't putzed about with the v0.1 base at all, but I think I've got a motor mount design that I like. It's got the split bolt setup for securing the motor (including a cutout for holding a 2-56 nut), and the legs are cool lofted dealies. Lots of radii...
It's been a minute but there is an exciting new update on Dodo! The original Dodo Playground is a bit long in the tooth and sadly Chrome Applications had been deprecated so there was no longer a good way to flash Dodo games directly from the browser. ...
Reading this Japanese article on a kit sold in Japan to build a Z80-MCB, I realized the presence of a possible bug seeing this two images: As you can see, there is a Z80-MCB without any Virtual Disk or RTC attached and in the resulting screenshot the...
Pleased to discover there are ready to use, non-emulation SD card mux devices available! These are great for 99% of the use cases folks message me about. https://wiki.tizen.org/SDWire SD Wire https://www.tindie.com/products/badgerdnl/sdwire-usb-c-sd-card-reader-sd-mux/...
Size: about 50x50mm (size of condoms I have, could be a little larger if required)Layers: preferrably a single 2-layer PCB, for easier ordering at the usual suspects in ChinaConnections: debug UARTMicroUSB for charging the batterytemperature sensor connectortwo...
I made a 5V, 5W buck derivative that is smaller than the flybuck design but uses the same input/output filter design for low noise/ripple applications. The inductor core is a Magnetics MPP C055048A2. with 38 turns of 24 AWG. Peak efficiency with...
The PCB arrived and they look perfect, not that I had any doubt when ordering at a big Chinese manufacturer. And of course there are mistakes :/ The voltage regulator for USB power to the GPS chip U5 has the wrong footprint. I used a SOT-89-3 foot...
Hey all!This is another project log to update the latest developments of OWL (Just in case you forgot, we call it OWL because, well, Open Indirect Ophthalmoscope, OIO).So, since the last time I made a log, we’ve been working on--making an elegant GUI...
Requirements Easily found when misplacedBig enough to hold easily but not too big that it's cumbersomeShould have a battery compartment so that unskilled personnel can replace batteries without having to open up the housingRoom enough for the necessary...
I decided that once I get this project working well, that I might make several for family and friends that might need something like this. To that end I placed an order for some HC-SR04 (Ultrasonic Ranging Module) and the HC-SR501 (PIR Sensor) modules...
FlexSEA-Plan is an embedded computer used for high-level computing. It boasts a powerful processor and can run an operating system such as Linux. Developing code on this platform is similar to the regular (i.e. non-embedded) software development process....
I modified Android application and Control Unit firmware so that front lights can also be controlled (brightness, blinking mode) via Bluetooth. Previously only rear lights settings were being sent from the phone. Now Control Unit receives all the settings...
