SMD August – Cooking SMD Stars

For SMD August we’re breaking out the toaster oven and controller to cook some SMD stars.  Participants are likely to end up with a working product but they’re more likely to end up more knowledgable about the electronics fabrication process. Apparently real SMD hackers only use solder paste and toaster ovens so we’re here to […]

MakeyMakey Bootloader programming over ICSP

I’ve been asked about how I programmed the bootloader so I’m putting the doco here. For all my AVR work I use a bus pirate v3 with the stk500 firmware. I have a cable I made that adapts the bus pirate to the 6 pin AVR ICSP connector. For MakeyMakey I made an adapter cable […]

SMD July – Build MakeyMakey on July 24th at VHS

When Kickstarter came to VHS to talk about launching campaigns they showed MaKeyMaKey as an example. They chose well. This has to be close to the most fun you can find in a circuit. You can find out lots about it online, it is even more fun than it looks! MaKeyMaKey is open hardware, all the […]

LED Wall of awesome nearly funded!

by Dan Royer Several weeks ago our wonderful wall of LEDs returned to it’s Burning Man owners. It was 10×42 pixels and loved by all. To replace it I’m running my third VHS funding drive. (The first was an 3D printer filament group buy, the second was the group quadcopter buy with Jon G.) Every […]

SMD Soldering Beginner Workshop

This is a beginners SMD workshop. You’ll be taken through a technique for solder smd components and then get a chance to build the board shown in the photo.  The price is the cost of the parts including battery. People should have some soldering experience – the focus will be on SMD soldering, not soldering […]

SMD May – programming jig

  This week we’re building Logic Pirate open hardware logic analysers at VHS in our SMD workshops.  The ICSP header is 0.05″ pitch so I came up with a top and bottom programming jig to load the initial firmware.  Tickets are closed, if there is demand we’ll re-run the workshop later this year. The LP […]

SMD May PCBs arrive just in time

The circuit boards from dirty pcbs for SMD May are here just in time. The Logic Pirate is a nice cheap compact logic analyser design by Markus Gritsch. More at Dirty PCBs and Dangerous Prototypes.  

SMD May – Logic Pirate

      The dangerous prototypes logic pirate is a new 8 channel logic analyser design from the home of the bus pirate.  It uses the open SUMP protocol supported by the ols java client software (Mac, Windows, Linux). This project is of similar difficulty to the internet of things arduino, except none of the chips are […]

SMD April – USB Isolator overview

You can see from looking at the block diagram above that the isolation is transformer based, it’s quite remarkable that they can fit 5 transformers in such a small package.  If you can’t attend the workshop the pcb files can be found on github and all the parts at Newark/Element14. Newark/Element14 have an excellent video […]

SMD April – USB Isolator

In one of the earlier SMD workshops I managed to temporarily kill my new macbook pro when I plugged in a prototype.  I revived it by removing the battery all the time chanting to myself, must get a usb isolator, must get a usb isolator, must get a usb isolator….. This is a nice simple […]
