Open Bench Logic Sniffer / Change Flash
some time ago I tried flashing my OpenBench Logic Sniffer since than I do have trouble using it. In particular it doesn't give back any metadata. From time to time I can make use of the ols-client software but most of the time I can't use it. Same happens with sigrok-cli and pulseview doesn't work at all since it checks metadata ids.
Flashing PIC-firmware works, but unfortunately I can not get bit-files uploaded.
I do not want to throw it away I liked it the days it worked, I suggest it is the onboard winbond flash. Could this be damaged for any reason? Unfortunately I couldn't get the flash chip on digikey/mouser. Has anyone a sourcing hint for me, or any other idea what I could do to make sure the device is not waste at all?

Ever since I found a source for inexpensive Stainless stencils ($20 for unframed, $40 for framed) I rarely hand solder prototypes unless there are only a few components.
would you like to share your source for stainless stencils?

Tools of the trade / Re: Controlling Hot Plates
Actually the only reason I want to use temperatur regulated reflow soldering is because of the WS2812B. I've successfuly soldered with a 5mm aluminium plate on our home ceramic oven 4 layer pcb's even with qfn's - also with skillet and an aluminium plate inside, where I removed the pcb once the solderpaste starts melting. This way I mostly had my soldering under control untill I wanted to have these nice WS2812B. Some of them get damaged whenever I do it that way. Soldering with a normal soldering station works without problems. Obviously these leds are too sensitive in terms of temperature.

Tools of the trade / Re: Controlling Hot Plates
thank you very much for your answer. I've seen Wills reflow oven which looks really nice. Indeed it might be a much better solution but since lack of space in my tiny lab I had the idea with the hot plate.
Do you think the results with a toaster oven would be better?

Tools of the trade / Controlling Hot Plates
I've seen Ian using one of these small hot plates in a video http://www.aliexpress.com/item/Free-shi ... 26294.html
Since I can not place a large pizza oven into my work room I was planning to get a hot plate. Does someone know if these can be manipulated easily in order to add controlling temperature abilities to the device?
Is someone using one of them and how satisfied is he reflowing his boards?
Thank you very much in advance,

Breakout boards / Re: FT2232 free PCB - not working, help requested
If you ask me Dereks board is not that bad. Actually it is a matter of balancing with flux. I saw on one of Ian's videos "Beers in Akiba’s Workshop" talking about a Kester flux. Unfortunately I can't get it in Germany, but it did sound very promissing.
Altough I could make use of several DP-Boards It gets boring adding comments there without success.

Breakout boards / Re: FT2232 free PCB - not working, help requested
I was fed up waiting for a coupon in the free PCB drawer where I took part several times in order to get a breakout board. I ordered the pcb on oshpark and build that ft2232h breakout myself since I had most of the parts at home.
attached is an image where I communicate with my phone through the board.
I've on pcb left, if yours is damaged I could provide you one.
