This post brings you a nice alternative if you need a usb programmer and don´t want to spend the huge amount brands charge nor buy a cheap one from China and wait for the long shipping. Or, in other words, if you just want to build it yourself and have fun.
It´s a very simple approach to build your own USB Blaster Programmer, using a PIC 18F2550 (same as in the original design), apart from the micro, you will only need some passive elements. This design is for a 3.3 V level. You can easily get around this by adding some level shifters. The Eagle files for the PCB are available here.
Finally, you might be wondering why I said the original design. This USB Blaster Programmer design belongs to a Japanese guy who published it some time ago (yes in Japanese). You can check the original tutorial, for which you will need the help of Google, if you can´t read Japanese. It´s necessary to read it as you will find the part list, circuit diagrams and some helpful tips (you will need to read more than one time as it´s a machine translation…).
Hey gadgetheads! Just a quick note: we recently added a couple of new products to the Gadget Factory Store. The first is a killer USB battery pack that you can use to juice your Papilio when you’re on the move. We just got these in, and we’ve got them very reasonably priced at $26.99 – yeah, just for you. Zap over to this little guy in the store here.
- Uses 4 AAA alkaline batteries or 4 AAA Ni-MH batteries to power your Papilio and other devices
- You can also recharge 4 AAA Ni-MH batteries from the USB port
- Input: DC5V/400mA
- Output: DC5V/400mA
- Interfaces: USB+USB 5pin
- Comes with USB charging cable
- Batteries not included
The next newcomer to the store is something you’ll need for the Retrocade Synth, or any other audio hardware for that matter. Our new audio adapters are female 1/8″ TRS to male 1/4″ TRS and are gold-plated for optimal audio quality. It’s always good to have a few of these on hand, so make sure you are equipped! These guys are only $3.99 for a pair. Zap over to this one in the store here.
So that’s the long and short of it. Stay tuned to the blog, as we are adding a grip of new products to the storefront in the weeks and months to come.
If you still haven’t seen our new storefront, you can check out the store’s main page here.
Papilio user Magnusk made a very interesting FPGA board that he calls Pipistrello, in the past he used some different papilio boards and he like them but he wanted a board with HDMI interface, lots of RAM for buffering, high-speed USB for data streaming and SD-card for data storage.
So the only option left was to make my own board – basically merging the fpga and LPDDR from the LX9-Microboard with the formfactor, wing interface and tool-set from Papilio, then adding all the needed interfaces on-board (and then some more to make it more interesting).

Here is an interesting project we found over at jayakody2000lk.blogspot.com the project is called Kidogo, it is an 8 channel USB Digital Signal Injector. Definitely worth a look:
“Kidogo system consists with Signal Editor and USB interface module. Kidogo Player is the Signal Editor of the Kidogo system and it can support up to 512 time slots (each range between 1ms to 1s) with 8 channels.”
The Kidogo Player is designed for Microsoft Windows OS and it has many features, we can list some of them here:
- Save waveforms and settings as binary file or export waveform as a text file
- Playback controls such as “Play to segment”, “Play from segment”, “Step back”, “Step next” and “Clear”
- Shifting and rotating waveforms
- Invert, Reset, Clocking and Binary Generator functions
- Mute function to each individual channel
- Launch without any installation or configuration
Kidogo is an open hardware project and the original article is complete with full source code and PCB designs.

Feel free to discuss this project in the comments thread.
