Board Designed, Reworked and Off To OSHPark
Log from Solare: Solar Lithium Battery Chargers
So yesterday evening I banged out the schematic and PCB for the BQ24210 of the Solare boards. After spending the day doing other designs I came back to it and reworked it significantly. I feel the newly revised design is superior to my initial pass....

Trig accuracy issues (and a possible solution)
Log from Arduino Graphics Card
The cube I had been rendering did not calculate for camera pitch/yaw, so if it was a 3d game you would only be able to look in the +X direction. I added some math to fix that, but then I got another problem.I wasn't using floating point numbers,...

It's over 9000
Log from Game Boy Cartridge plus Programmer
Too. Much. Overkill. what started as a basic teensy++ 2.0 based cartridge reader/writer is now a full blown project with a nokia 5110 LCD display with rgb backlight, 3D printed, vintage looking case, pcb for an at90usb1286. At least in my head. Please....

The meassurement of the Load cells inside the body scale is performed through a HX711 ADC/PGA module from Aliexpress. It is capable to directly output 24Bit of the actual value.To display the value there is a HD44780 display. I fitted the display in...

complex shape coil
Log from (re)Mangetizing neodymium magnets
Yay! I just had success with impriting a more-or-less complex pattern into the magnet.Making the coil wasn't fun though.I 3d-printed a plate with a channel for the coil. Then I wound a coil of right length between two screws, and packed it into the channel....

Life goes on
Log from 1Kb Space Invaders
Just a quick update now that the dust has settled after the judges results are out. I´m still working on this even if the hope of a nifty 3D Printer or any other price is now officially crushed. No hard feelings, there was some serious competition,...

Previous Work: A Wearable Posture Monitor
Log from HeadUp 2
Another on of my posture monitor projects again involves an Attiny85. While my previous sensors were either fixed to a chair or desk, this time I wanted to create a wearable version, that would allow for free movement. An ADXL335 is used to measure the...
