BlueSCSI 1.1-a DB25
Eric Helgeson Mar 06,2022
BlueSCSI provides a convenient way to use MicroSD cards hard drives in your Vintage Macintosh or workstation.This DB25 variant plugs right into the external port of your vintage computerSimple Design – Place a file on an SD card and go. Nothing to configure or setup.Power Options – In most cases it is powered directly from the SCSI bus. If your bus can’t supply enough power it provides a berg power connector or via USB.Performance – Up to 1024KB/sec Read, 912KB/sec write.Compatibi...

3 line to 32 line output expander
Yap Mar 04,2022
This project is described at Hackaday.The minimum lines required to use this board are: GND, SER (data), SRCLK (shift), RCLK (strobe). Vcc depends on the power arrangement. You should jumper the ~OESEL (output enable select) to ground if you don't wish to disable the display by signal, or vary the output with PWM, from a controller. The ~SRCLR input is only needed for resetting the output by the controller.This board is designed with optional aspects you can choose to include or not:As mentioned...

Talking CR Timer
Donners Mar 02,2022
The StoryImagine working at the office from nine to five punching numbers in a computer the whole day...All you have to hold on to is your coffee break! Fortunatly, it is not that black and white for most people. We do have something in common though. There is a time that each and everyone of us needs to take a bathroom break. At some point, all the coffee we drink needs to leave the body, doesn't? So you are on your way to the comfort room as you where holding up every drip of coffee while fini...

Arduino MKR WiFi 1010 SPI Flash memory shield
Mischianti Mar 01,2022
Arduino SAMD (NANO 33 and MKR): SPI flash memory FAT FSI have a couple of Arduino MKR WiFi 1010, and It’s potent, but I notice a tedious lack: there isn’t a Flash memory to store data. I have already written some articles on controlling external SPI Flash memory “How to use external SPI Flash memories”, but now I’d like to simplify the process, and I create a simple PCB shield to add external SPI Flash memory in the fastest way.The PCB is straightforward, and I added some jumper soldered to sele...

Wireless Energy Transmission System only using PCBs
Arnov sharma Mar 01,2022
Hey guys how have you been!So here's yet another crazy experiment based on the work of Mr. Nikola tesla.My Edition of "WIRELESS ENERGY TRANSFERRING SETUP" was made entirely from PCBs.The only difference between Mr. Tesla's version and mine was that my setup didn't work as it should.All the joke aside, my setup does work but the problem is the efficiency.Why it's not working efficiently?Well because the design of the coil is a joke. I added many traces and didn't leave too much space at the cente...
