content: Convert your audio DATs to digital format on a PC. This laptop will read, write and play audio DATs. Unlike using SPDIF, there is no copy protection. Unlike analog methods, there is no conversion loss. What is on your tapes is what you get.This is a custom built system for transferring audio DATs to a computer as lossless WAV files. You can later convert them to MP3, FLAC or other formats if you wish. I built two similar systems for a major symphony orchestra, to convert their library of over 5000 DATs. I built this one for me, but just don't need it any more. When it's gone, I'll be done messing around with DATs.System consists of:Dell Latitude D830 with Windows XP* 4 GB RAM* 220 GB solid state driveAdaptec SCSI interface for DAT driveSeagate SCSI DAT drive with special audio firmwareSCSI cable and terminatorCharger for Dell laptop, and power cord for DAT driveSoftware to read, write and play audio DATs (read/write is x2 normal speed, play is real time)The software will support two DAT drives simultaneously, but only one drive is included. I do have a spare programmed circuit board if you can get another DAT drive of the correct model (untested, but should be OK).$1800 and I'll ship for free (in the US). If you want insurance, you pay extra.

content: Quote from: mojoe on May 30, 2025, 05:50:28 amNeat system. Double-speed transfers must be a godsend to people doing this!Honest question: why would SPDIF be lossy? It’s absolutely capable of carrying DAT’s native sampling rates and sample format. The ability to make bit-perfect copies over SPDIF is the entire reason the RIAA forced Sony to add SCMS to DAT.

content: The speed is actually 2.1 times, due to the workings of the drive in data mode. The two systems I built for that symphony orchestra had two drives each, so they could convert four tapes at once. It still is going to take them a long time.As for the SPDIF, I was mistaken in my wording. I was thinking of the copy protection. I'll edit my post.

content: I have a spare DC Bias board and matching Extender Board that I made which I want to sell as it's surplus to my needs as I made a couple of them at once.It is designed as a 100% drop in replacement with better specs than original (I used better parts than specified by HP where able).It is an almost 1:1 reproduction of the original part and is tested and calibrated as fully working (You might need to give it a little tweak in your unit to compensate for variations etc).All you'll need to do is drill two small holes in the existing rear blanking plate to attach to the standoffs on the PCB, plug it in, set the rear DC Bias switch to 'INT' and you are good to go.I'll provide a drilling template so you can get it spot-on.Asking US$55 via paypal, including shipping anywhere in the world.

The factory installed card 1 and the option 1944 card 2 are identical.Either a broken or a working one is OK. I'd rather not like to buy and rip appart a fully working instrument just for the card even though I know that they can be had cheaply sometimes.

I agree with thm_w, if these are for a job/production and/or you need them right away I'd just get some aliexpress ones. Only exception would be if you need a weird tip type. I've seen for the C245 they only appear to come in 3 varieties from China, so with the cheap ones you're stuck with those

timestamp: May 27, 2025, 08:57:32 am
content: This welder offers precision control of welding pulses from 10A to 1000A, including programmable ramp up/down times which can reduce spattering. There is a cap bank of 4x 0.56F at 16V which discharge through 40 paralleled FETs on a fan cooled heatsink, and an 80uOhm current shunt. The FETs are operating in the linear region, controlled by a PID loop targeting either the programmed weld current, head voltage or weld power. Can be single or dual pulse, where for example the first is specified by current, and the second pulse specified by power. The battery materials I've been welding work fine with current control. Apparently power control can be good for surfaces with some surface corrosion. So quite a well featured resistance welder.

It can observe and measure currents in PCB tracks and other conductors where conventional current probes can’t be used. This includes captive wires into components, the legs of integrated circuits, and PCB ground planes. The I-Prober 520 uses positional H-field measurement. By placing the insulated tip of the probe onto a PCB track, the current flowing in the track can be observed and measured. The I-Prober 520 is supplied with a clip-on toroid assembly which converts it into a closed magnetic circuit probe for measuring current within a wire.Current measurement from isolated probing of conductorDynamic range of 10mA to 20A peak to peakWide bandwidth of DC to 5MHzLow noise equivalent to less than 6mA rms at full bandwidthSafety rated to 300V Cat II (600V Cat I)Suitable for connection to any oscilloscopeHigh accuracy general purpose H-field probeConverts to standard "closed magnetic circuit" current probe------8<-----Currently (ha ha) for sale in the UK, including shipping: £500.Farnell flogs this for £706plusVAT, and not seen used for even close to £500 Nevertheless, this could be yours for only £450£400.Export might be possible given sufficient incentive, perhaps.

content: They are scavenging on local gumtree/fb marketplace. Not the first time I'm selling to movie studios on Gold Coast. The people who come and pick up are same, they just work for different studios. It looks 100% legit - they even fill out an ATO form that is used for buying movie props. Last time I sold a box of old dial up modems and vintage keyboards, it was a pretty good deal. That was used for a different movie set though. I think it is not a bad path for old equipment; after they've done with the movie, it ends up sitting at their warehouse waiting for another movie. Much better than ending up in someone's garage collecting dust or even worse, rubbish tip.

content: Up for sale are this two instruments from Advantest.The R6581T 8.5 digit multimeter doesn't have any serious blemish on the outside. All is in good shape, the only "problem" is a lightly faded VFD.On the TR6143 source measurement unit, the only parts missing are the rubber feet on the side and two of the rear feet, as I assume it was used on a rack. It works perfectly, and produces up to ±110V ±0.5A and ±32V ±2A. The unit is locked at 110V, but I include a small 500VA toroidal transformer, more than enough for the up to 340VA it can consume.I'm asking for 1200€ plus shipping for the R6581T, and 300€ plus shipping for the TR6143.Here are some photos in high resolution and the TR6143 datasheet:

content: Hey all,We're looking to sell our current pick and place line (Australia, NSW). It's been running smoothly for over 3 years and has pumped out thousands of boards reliably.There are 2x PnP machines: Neoden K1830 (8 feeders, full vision, new version), and an XY SMT660 (which is a HWGC machine with a different sticker, 6 heads, individual cameras for each nozzle). The K1830 comes with a full compliment of feeders including plenty of 8mm, 12mm, and 16mm electric feeders, and 12, 16mm, 24mm, 32mm, and a 54mm pneumatic feeders. These are Yamaha CL style feeders which can be used for the K1830 and SMT660.There's a semi-automatic YS350 solder paste printer which is fantastic for medium scale manufacturing.A 1 Metre Neoden electric conveyor, and an IN6 reflow oven which has never missed a beat.All the gear has been very well cared for in a clean environment. Located in NSW, Australia (will provide more details privately if you're interested).I would prefer to sell as a whole lot, but I'm open to selling individual machines separately.

content: You're funny, you come to this forum and post several messages within an hour to sell your stuff, then proceed to offer a 'deal' for a partner were the partner takes all the risks including the legal risks as your deal would circumvent taxes and tariffs. There is nothing that stops you from selling on Ebay yourself. Ebay is swamped by offerings from China.Btw, the prices you offer in those other messages are pretty on par with what is found locally in Europe or in the USA. Many prices on Ebay are only the seller's dream, so don't take them as a reference all too much. For the more expensive stuff it is important to be able to verify the equipement prior to the purchase and to show relevant documentation such as continued maintenance contracts and traceability of calibration, else the sales value is diminishing very rapidly.If you're serious and have trustable equipment for a good price, then PM your credentials and the list you have for sale. We buy entire lots, rarely single units. If you offer is worth it, I'll send someone over to your place.
