by Krzysztof Foltman After the initial success with LPC810, I was ready to work on something with more memory and more I/O. Searching the Farnell catalogue for simple, low-cost and hobbyist-friendly MCUs, I found the tiny STM32F030F4P6 microcontroller made by ST Microelectronics. The microcontroller The chip is based on an Read more
by Krzysztof Foltman This is my first successful attempt to do something with a 32-bit microprocessor in a circuit of my own making, instead of relying on commercially-available development boards. After some prior unsuccessful tries using STM32F051 and TQFP64 to DIP breakout boards, I decided to start over with something easier. Something that Read more
It has been quite a while since I had a chance to work on the tool – I have been too busy validating the output and playing with the microgameboy, but finally I’ve had the time to incorporate some bugfixes. The biggest one on the list has been the import Read more
The recent DirtyPCBs.com paneling experiment resulted in a nice new addition to our prototyping toolbox: the yellow panel. The yellow panel contains: Wolfsom SMT microphone breakout with small amplifier QFN24-to-dip adapter Freescale K20 TFT backpack (enhanced Teensy3.1 without the bootloaderchip) Freescale KL02Z DIP breakout with microphone USB-testpoint board in USBstick form Read more
DirtyPCB seems to be the first small-prototyping-service that allows you to build panels with breaktabs. I had to try this! Soon after this thought I stumbled upon the great question of “how” – here I had all these folders full of gerberfiles for boards.. but the tools to panelize them Read more
The Goldfish v4 user-interface board has been ordered! The new big protoboards too! A batch of tiny protoboards too! And a set of LED badges for the summer festivals where we shall be jumping around! Goldfish v4 UI board: Festival LED badge: Small Protoboard: Large protoboard:
Krzysztof Foltman writes: “Another PCB sent to manufacturing. This time, it’s a universal 5x5cm protoboard. If you’re a beginner at electronics and want to try making a simple electronic circuit using standard through-the-hole components, it’s probably going to save you a lot of time. It’s compatible with DIL chips but also Read more
After using our V1 prototyping boards for a while we decided to design some improved versions to make future experiments easier. This new board is focussed on mostly analog setups: It features a switchable supply between USB and external power and an area for SOIC MCU’s and CODECs. This board Read more
