Hi there, A followup to this mail from a couple months ago. I started with your USBtinyISP design and ended up with this. It’s not recognizably based on your circuit anymore, and it has a few more big features (dual power supply, JTAG programming, USB-TTL serial, rescue clock). But a little bit of the USBtiny’s soul is still
there! You can follow along with the development on my blog: http://www.sowbug.com/
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

[Disclosure: I laid out that board.]
Although this is a really capable little programmer, my favorite feature is a really low-tech one: The silkscreen on the back, with the map of the six pin ISP header. For some reason, I always end up needing to know the pinout at an inopportune moment, and that saves me a trip back to my computer.
