Quick Thing: Case for Diamex All-AVR Programmer
The Diamex/Tremex All-AVR programmer for ATmel microcontrollers comes as “naked” populated PCB, no case, no protection against shorts or other damage. I created a case for it, with the following design criteria:
- Protection against accidental shorts as good as possible.
- Easy access to the jumpers that control the various operation modes.
- “Park position” for the jumper that de/activates the external power (since it is often in “off” position and can easily be lost).
- LED signals need to be visible.
- Uses the existing mounting holes.

Title Image Project: LED Controller
To create a lamp with adjustable color temperature and brightness, I use a warm/cold white dual LED strip, an ATtiny45 MCU with N-channel MOSFETs and two adjustable resistors. This article contains the hardware and software setup. The title image of this blog shows the project.
