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 […]

Do you like candy? I like candy.

Here’s a very brief overview of the thought process for building something to amuse and frighten your neighbours. I originally wrote this up on May 31st and posted it elsewhere, but I thought I’d give the VHS regulars time to explore it on their own before I ruined the surprise. Some of the readers may […]

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 […]

Schlage BE365 deadbolt hacking

We have a keypad dead bolt on the front door that has been slated for adaption to rfid for ages.  About 6 months ago we dismantled the lock and tapped the wiring to the solenoid.  The solenoid is tiny, it doesn’t open the lock, just engages the knob so human power can open the lock […]

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 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 […]

SMD March – Internet of things board

For SMD March we’ll be building an Internet of things board. This is the heart of an arduino uno coupled with an ethernet interface to let you control leds, relays etc, plus read switch positions, temperature etc. all over Ethernet. Like a uno, it has a usb interface for programming with the Arduino GUI and […]

Fun with lasers!

Although, I guess “fun” is always implied when lasers are involved. I shouldn’t have even bothered.   Here are some things lasers are good for:   1) Organizing your kitchen.   2.) Clamping stuff   3) Holding worm gears   4) Showing up 16th century engravers   Anyway. I hope you’ve found this post informative, […]
